September 2019 – Native Plant of the Month
Written by Guest Contributor: Elenore Goode
Goldenrod/Solidago spp., Solidago canadensis/Tall Goldenrod
Late summer in Texas is a tough time for a plant to begin to flower, and the many perennial species of Solidago that grow across the state are some of the most dependable plants for wildlife to find blooms on at this time, despite any heat and drought. Growing everywhere from wetlands and prairies to drylands and cliff faces, Goldenrods are a very adaptable and diverse genus of plants that have much to offer humans and wildlife. The different species also have a variety of growth habits, from small clumping species, to some that will spread quickly through their roots, and go as far as they can reach.
Their bright yellow hues are a welcome sight for pollinators at the end of a tough summer. Goldenrods can be counted on to tough out the worst and still show their best colors. Solidago blooms are often super loaded with a great variety of pollinator species buzzing around them, since they provide a vital surge of rich pollinator forage at a time when many insects and other plants may be trying to recover from a harsh summer before winter.
Goldenrod’s flowers and leaves have also long been recognized as having useful medicinal qualities, and remain popular as a hardy wild remedy plant in many pollinator gardens.
The drought endurance, ability to grow in poor conditions, and rapid-spreading habit of some species may also make them too vigorous for companion planting in vegetable and herb gardens. However, these same qualities make those species ideal for re-vegetating ecologically-degraded areas with beneficial plants for wildlife, and are a great choice for areas with poor soils and low species density. Even in gardens, they can be carefully introduced (especially in more depleted soils that need organic matter) and used to suppress other plants like Bermuda grass, or to provide just enough shade for herbs and veggies in late summer, when not allowed to smother them.
These hardy but aggressive species of Goldenrod are great as support plants, and excel in wildflower borders, hedges, and tall grass prairie settings. They do best when they are allowed to grow in dense colonies, or with other tallgrass prairie plants for structural support.

Pecan – Scientific Name: Carya illinoinensis
Written by: Kirby Fry
The pecan tree is iconic. It is a tall, beautiful and agriculturally productive native tree.
The pecan tree is also the state tree of Texas.
Since the 1880’s the United States of America has become a major producer of pecan nuts, which are actually drupes or stone fruits, harvesting 264.2 million pounds of pecans annually as of 2014. Mexico and the US of A account for 93% ton of the world’s pecan production.
Growing up in Houston, Texas, my second story bedroom was perched over our neighbor’s single story house which had a metal roof on it. I remember hearing pecans falling from their pecan tree and hitting that roof all throughout the fall. During those fall and winter months there was also a wooden bowl that sat out in our dining room which was full of pecans. Nearby was an assortment of tools used for cracking open the shells and picking out the delicious fruit inside, we had contests to see who could “shell” the most intact pecans.
Right around the fall equinox, pecans are ripening here in Texas. This is a really good time to start thinking about planting your very own pecan trees.
The pecan tree can be planted from late December through early March and will do well in every county of Texas. They are typically sold as bare root stock with a 24” to 32” long intact tap root.
The roots of a pecan tree should be kept moist from the time of purchase to the time of planting.
At least 2 or 3 different varieties should be selected and purchased for cross pollination.
Cultivar pecan trees are grafted and chosen for the sweetness of their fruit, the thinness of their shell, and the alternating years that they produce. Pecan tree growers are careful to select trees that yield pecans during alternating years, as a pecan tree will produce one year and then possibly skip 1 or 2 years of production.
Several varieties of pecan trees are recommended for Central Texas. These varieties include – Sioux, Choctaw, Wichita, Cheyenne, Pawnee, Forkert, Cape Fear, Kiowa, and Caddo. They have all adapted to river and creek bottoms, preferring deep well drained sandy and loamy soils, though I have also seen them do well in clayey soils that have good drainage.
Select a site to plant your pecan trees that is at least 20’ away from your house, and away from driveways where cars will be parked. Pecans are large trees that tend to start dropping large branches after 20 or 30 years of growth. If planted close to your home, they will need careful pruning later on in their life cycle.
Pecan trees should be planted 35’ apart from one another in order to give their massive root systems plenty of room to develop.
The hole you dig for them should be as deep as the tap root is long (sometimes 32” to 48” deep), with the objective being to replant the tree as deeply as it was planted at the nursery. The soil line on bare root trees can be determined by the color of the bark.
Because the hole you will need to dig for a pecan tree will be deeper and larger than most fruiting trees, the tap root should sit firmly against the bottom of the hole you dig to avoid undesirable settling. The hole should be carefully back-filled and watered in, in order to prevent branching roots from settling or sinking too much as well.
The tree should be watered in with at least 5 gallons of water per tree immediately after planting.
The time needed for the tree to begin production takes close to 8 years, after which the tree will begin to yield 10 pounds of pecans per year and up.
Tree Fertilization and Maintenance
A nitrogen fertilizer should be the only soil-applied amendment that your pecans need. Alfalfa meal, feather meal, bone meal, and/or blood meal should be applied in small amounts throughout the growing season. These are low or moderate sources of nitrogen and you could easily double the amount applied when compared to high nitrogen fertilizers.
About 1 pound of high nitrogen fertilizer (21-0-0) per inch of trunk diameter should be applied each year. Keep high nitrogen fertilizers away from the base of the trunk in order to prevent tissue scalding.
As the trees mature into their 7th or 8th years of growth, avoid applying high nitrogen fertilizers after June in order to prevent a flush of new growth getting frozen back in the fall.
During the first 7 years of growth, a zinc nitrate solution should be applied in a liquid form to the surface of the leaves, 2 to 4 teaspoons per gallon of water or 1 to 2 quarts per 100 gallons of water. Pecan trees deficient in zinc will have smaller, weaker leaves and leaf stems and in extreme zinc deficiencies the trees will experience a higher rate of die back during harsh summer and winter conditions. This zinc emulsion should be sprayed on the trees every 2 weeks or so during the growing season.
Water your pecan trees from March through September for the first couple of years after you plant them. During the summer time your young pecan trees may need 2” of water per square foot of growing area, one time per week.
Low emerging braches (a.k.a. trashy trunk) should be pruned back each winter, and care should be taken to select and preserve a central leader for the top of the tree. Try to avoid allowing a “V” to form in the tree’s trunk as pecans grow to be large and somewhat brittle, and a forked trunk will often crack and split.
Maintain the area under your pecan trees and keep it free of brush and tall grasses during the fall so that the fallen pecans can be more easily harvested. Once your pecan trees are established after 8 years or so, fertilize and water only as needed.
Harvesting pecans is a great way to supplement your fall and winter diet. Pecans also have a high market value and can be used to feed pigs during fall and winter months.
Take a look at your property, and find a good place to plant a few pecan trees.
Our PDC Grad Interview Series is back!
Our hope is to convey what a life-changing opportunity the Permaculture Design Course can be, while learning more about what first attracted these former students to sustainable design and how they have applied those principles since taking a PDC.
We’re continuing this series with small-business owner Michael Wolfert of Symbiosis Regenerative Systems – read more below.
1) How did you become interested in sustainable design? Please describe to us any moments in your life that piqued your interest in sustainable, regenerative, and holistic systems.
I had a deep feeling of despair in my late teenage years and early twenties. At the time I was mostly seeking ways to reduce my footprint and be an activist for policy change and reform. One day a friend of mine, Joshua Adair, called me up and said that there was a potential scholarship for a permaculture design course. I said, “what the heck is permaculture.” He said “It’s like gardening, natural building, community building and learning to live more sustainably!” and proceeded to give the details of the event. I said I would have to think about it. We hung up. I thought about it for literally 1 minute, called him back and let him know I was really excited to learn about this and incredibly grateful that there was a scholarship because I would not have been able to afford it at the time. I started to do some research and prepare for the PDC, though I still had no idea the rabbit hole I was about to enter.
2) What were you looking to learn when you signed up for a permaculture design course?
I didn’t have many expectations, having just stumbled upon the concept with very little time to consider the implications and the impact they could have on my outlook and life.

3) Who taught your permaculture design course and when? What did you appreciate about that course, and what would you have liked to have learned more about?
Kirby Fry, Gary Freeborg, Jenny Nazak and Ted Norris.
This course was a real turning point for me. Kirby led the majority of class time and he did a great job introducing me to the idea that we might actually strive to have a positive footprint instead of just trying to eliminate our negative footprint, and that in this practice we could aim to set up positive feedback loops, modeling our designs after ecosystems.
From that point forward, I knew what my driving focus would be. I would try my best to become a mutually beneficial symbiote with my ecosystem. An agent for making connections between the correlating outputs and needed inputs of the systems around me. Nudging ecological succession forward. Taking more responsibility for my family’s needs, consumption, and outputs. Striving to leave a legacy of regeneration in my wake. It’s a lifelong pursuit that I hope future generations will be able to carry forward.
4) What other courses, if any, have you participated in that have helped you to learn more about and implement sustainable design systems?
Working at Morning Glory Farm with Gracie Brousard and Richard Lindley was my first real-world continuing education. These folks were real eco-pioneers and all-around fantastic mentors. I was very lucky to find them and to be allowed to study farming with them. I worked there for nearly 2 years as a farmhand. During this time I lived primarily in a school bus with no running water or power. The meals Gracey would make from the produce they grew and goods they traded other farmers for really opened my eyes to what eating fresh and seasonal produce would be like. they were both extremely patient and kind. I learned a ton about gardening, farming, community building, and being a mentee.
Cypress Valley Farms was my second continuing education course where I worked as a co-farm manager in an attempt to start a profitable regenerative farm. I learned so much from this experience and the property owners that it’s hard to summarize. Some of the main takeaways were to focus equally on the business and marketing of your farm as you do on the growing of produce. Make clear agreements with all decision-makers – 1 hour of energy input here on the front end could easily save 10 + hours of confusion on the back end. Establish a healthy work-life balance and don’t let being a business owner consume and burn you out.
Hill Country Natives was my third continued education course. Here, I worked with Mitch Mitchamore to cultivate an intensive food forest in Leander, Texas starting with 6 inches of topsoil sitting on hundreds of feet of rock shelf. Mitch runs a fantastic nursery for natives and fruiting adapted plants but often says the main yield of his business is education, conversation, and connection. He takes as much time as needed to work with each client personally. He gave me a lot of freedom and trust to come up with experiments and implement them on the grounds at Hill Country Natives. Some days, we would be working at the potting trailer for many hours having wide-ranging discussions and being eaten alive by mosquitoes. I learned a lot about leadership and problem solving from Mitch and a lot about food forests and native plants from the work we did together.
I worked for Paige Hill-Oliverio of Urban Patchwork as I was just getting my business started, doing landscaping installation and maintenance gigs in Austin. I learned about being a contractor, spreadsheets, and integrating art into a functional design. Paige does great work and I still enjoy collaborating with her on projects to this day.
Teaching a food forest workshop with Caroline Riley-Carberry, Food Forests For All, three years in a row was a powerful learning experience. We taught people the basics of food forest design and the underlying principles, lead them through a design process, and implemented the design over the course of three days. Some of the results are on display at the Whole Life Learning Center, where a field has been transformed into a thriving food forest that is managed by Caroline with help from the whole life-learners. Seeing the iterations and receiving critical feedback from the systems this course worked to design and install furthered my understanding of food forestry and permaculture in general. Caroline taught me a lot about facilitation and design. I believe some of the initial collaborators that started the permablitzes and eventually Earth Repair Corps first began putting heads together at FFFA 1. I love seeing a ripple effect of positive actions after good people get together and get inspired by a common goal.
I traveled to Michigan to learn from Mark Shepard with Pete VanDyck. I learned from Mark that the economics of large scale permaculture farming are tricky and that you have to be creative and strategic to make your way in this space. I learned that small farmers can leverage their power as co-ops to compete against big ag and revitalize agricultural communities. I learned about designing systems that can be managed by machines at scale in order to compete against big ag without compromising the regenerative metrics of success we strive to meet. I also hosted Mark to teach a workshop at our homestead when we had just started renovating the place and learned not to host workshops until your infrastructure is in good shape. The workshop was a success and I learned more from Mark about his philosophy, and made wonderful connections with local like-minded folks.
I was a participant in TexRex with Darren Doherty, where we learned the Regrarians method of property design. This was Darren’s adaptation of the Keyline Scale of Permanence, based on years of experience designing large scale regenerative properties. This method has been a huge help in systematizing my design process and presenting information to my clients in a clear, digestible package. I learned a lot about rotational grazing, mapping, keyline design and much much more. This is one of the best workshops I’ve ever attended in that I took home more practical advice and methodology than any other, had a lot of fun between classes, and the food was delicious! I gained a ton of inspiration from Darren, Lisa, and the other participants.
I’ve learned from the Permablitzes, and seeing the updates from those systems installed has helped me to have more iterative feedback to improve the designs that I create.
I’ve been running my own permaculture/regenerative design and installation business for nearly 6 years now. We have worked on over 100 individual projects, and being able to monitor these systems gives me even more data to draw on for improving the design, installation, and maintenance methods we use for all things regenerative.
I’ve been living on my own homestead for nearly 4 years and am constantly learning from observing ecosystem succession in outer zones as well as the inner zone experiments and systems we’re running out here. One standard question I have to ask myself when installing a new system is: will I be able to maintain this with my 3 kids in tow or even better get them to help me with it? How can I make this accessible and fun for our family flow? That’s a pretty fun design lense to look through.
5) Have you been able to apply what you learned from a permaculture design course to your life, and business endeavors? If so, please elaborate.
Yes! As you can probably tell from my list above, I dove in headfirst and never looked back.
I’ve been doing permaculture professionally for nearly 6 years. We have 8 full-time employees including myself and a great network of independent contractors we can call on for collaboration. We’ve continued to gain momentum and improve our methods each year. Although it is a marathon of hard work, I love it. The projects we work on, the team we work with and the clients who have chosen to lead the charge in this effort keep me constantly inspired, learning, and growing.
For the last 4 years, I’ve been living on a 25-acre homestead with my family. Even though I grew up in cities and suburbs, as I got older I never really felt like I could relax when I lived in the city. The frenetic energy, constant background noise, light pollution, air pollution, the heat island effect, it all just got under my skin and made me uncomfortable. I didn’t want to raise my kids in a place where we were so reliant on seemingly fragile systems. I wanted them to grow up with the freedom to roam in the woods, get muddy, grow food and see the magic of nature unfold over many years. I don’t know if they’ll thank me for it, but I wouldn’t have it any other way and the turning point was my PDC. Each year we are more self-sufficient as we find our place within this context and ecosystem.
6) Have you had the opportunity to teach, mentor, and/or pass on information about sustainable design to friends, family, or employees?
Yes, I’ve worked with hundreds of clients, taught at least 100 students in workshops, have taught some co-workers, and worn out my mom with my ecovangelism. I’ve also learned a lot from these interactions and continue to meet really cool folks from all walks of life who all agree that sustainable design is a good idea.

July 2019 – Crop of the Month
Tomato – Scientific Name: Solanum lycopersicum
Written by Guest Contributor: Jennifer Goode
Tomatoes are the most popular garden vegetable crop in Texas, likely due to the relative ease with which they can be grown. Tomato season can easily last from April until October in most parts of the state, or even longer if there isn’t an early freeze. In Dripping Springs, we currently have a plot of 6 tomato plants that has been producing dozens on a weekly basis since June.
If you missed the opportunity to plant tomatoes during the spring, you can plant transplants through July and take extra care of them until they’re ready to produce in the fall. Tomatoes grow well in most Texas areas if planted in nutritious soil that drains well. They generally need at least 6 hours of sunlight each day, but the mid-summer sun in Texas can be too extreme. It is recommended to devise a way to shade the plants from the western sun during this time of year.
Texas gardeners can grow a variety of small and large fruit tomatoes, including Cherry Grande, Juliet, Red Cherry, Small Fry, Big Beef, Big Box, Celebrity, Homestead, among many others. The first thing to determine is how much space you have for your plants.
Tomatoes come in Determinate and Indeterminate varieties. Determinate varieties usually put out a large crop at a time and are ideal for container planters, or for gardeners who have the ability to preserve their harvest. Indeterminate tomato vines continue to grow and fruit over a long period of time. They require larger, sturdy cages and are not suited for container planting.
Soils with a significant amount of organic matter are best for tomatoes. It’s recommended to spread 2 to 3 inches of organic matter, such as compost or leaves, over the planting area and then mix the material into the top 4 or so inches of soil.
Most tomatoes will need to be planted at least 3 feet apart, but some varieties may require more space depending on their vine size. Proper airflow between the plants is important to prevent mildew.
You will want to plant each transplant slightly deeper than it was previously growing. Make sure the soil is loosely packed around the base of the plant, and that you leave a “donut” around the plant base to help hold water. Adding mycorrhizal inoculants will benefit the plants’ ability to absorb and retain water and nutrients.
Fertilize the plants every 3-4 weeks with one to two tablespoons of fertilizer. Once the plants begin to flower, add one to two inches of compost to the plant base for extra nutrients to help the plant develop its fruit. Liquid seaweed is also recommended during this time.
Tomatoes are susceptible to a variety of pests, and there are a variety of methods to address these ranging from seaweed extract, molasses, cornmeal, neem oil, garlic, and more.
Usually, you can find capital letters on tomato plant labels that note which diseases that particular variety is resistant to. Some of these notes include:
- A – Resistance to alternaria leaf spot
- F – Resistance to fusarium wilt
- FF – Resistance to race 1 and race 2 fusarium
- L – Resistance to septoria leaf spot
- N – Resistance to nematodes
- T – Resistance to tobacco mosaic virus
- V – Resistance to verticillium wilt

Inland Sea Oats/River Oats/Wood Oats, etc – Chasmanthium latifolium
Family: Poaceae (Grass)
Chasmanthium latifolium, like many native plants, has been severely reduced from its historical range by centuries of overgrazing due to its high palatability.
Dense mats of Inland Sea Oats can slow and infiltrate large volumes of water, and will catch and build soil in places that were previously eroding away.
Earth Repair Corps Teaches 2nd PDC at Texastopia Farm in Blanco, Texas
January through June, 2019
Written by: Kirby Fry
All Images © Woody Welch 2019
This past winter and spring of 2019 Earth Repair Corps had the privilege and honor to teach its second permaculture design course at Texastopia near the headwaters of the Blanco River. The design course consists of 72 hours of classroom instruction, group activities after lunch, individual and group design projects which are presented to the class, and a talent show on the last evening of class.
The classroom provided to Earth Repair Corps by Texastopia offers a great learning environment for both teachers and students. There’s comfortable seating and tables, a 4’ tall by 16’ wide dry erase board, a “close throw” projector with a pull down movie screen, surround sound, dimmable lights, and a fabulous air conditioning system. ERC couldn’t ask for more.
The course curricula covers the first 9 chapters of Bill Mollison’s book, Permaculture: A Designer’s Manual, and then goes over specific design systems for the home moving outward from there to the areas closest to the house and then out into the broader landscape.
One distinction of this spring PDC is that we have been making an effort to emphasize the difference between design methodologies and design systems, and so along with methods of permaculture design, Earth Repair Corps has also been teaching Yeomans’ Scale of Permanence 1 and Savory’s Holistic Decision Making Process 2 .
This spring, thanks to the speaking and recruitment efforts of Pete VanDyck, we had 3 members of the Edwards Aquifer Authority (EAA) attend the PDC. Carol Patterson, Mark Hamilton, and Thomas Marsalia all attended representing EAA’s board, upper management, and field technicians. EAA has tens of thousands of acres on the Edwards Plateau in conservation easements that it oversees and is looking to implement soil and water conservation methods that were discussed during class on a model site. Their design project was phenomenal.
Along with many other great students were two of ERC’s partners, Randie Piscitello with Goodwater Montessori Public Charter School, and Jennifer Goode with Texastopia and ERC attended the course and earned their PDC certification.
Class Curriculum & Activities
Our guest teachers included Shelley Belinko who taught about design principles and methods of design, Heather King who taught about annual vegetable gardening, Travis Krause who taught about running a family farm and animal systems, and Peggy Sechrist who taught about Holistic Management and intensive cell grazing.
One of the activities that the class participated in was using the radial laser level to layout two conservation terraces and a level sill spillway above Texastopia’s road leading to the Blanco River. Then, by the time the class resumed the following month, Pete VanDyck and Texastopia had installed the terraces, planted them with native trees, and mulched them with straw. It was a great design process for the class to be a part of.
About a quarter of the way through the course, day 3 or so, the students begin their design projects. This spring PDC we allowed a wide range of projects including group and individual projects, as well as onsite and offsite projects. This gives students the opportunity to work on designs for their own properties, and or work together as a team on site if they do not have land of their own. I was especially impressed with the design project that the EAA team presented for a piece of land that may soon become a lab and working model for soil and water conservation methods on the Edwards Plateau. All students are encouraged to make use of Yeoman’s Scale of Permanence and Google Earth Pro for their presentations.
The evening before the last day of class we held a talent show. Bill Mollison always had a talent show during his PDC’s and joked that if you don’t perform in the talent show you wouldn’t graduate. What I usually experience is students being surprised and a little uncomfortable before the talent show, but really opening up and having a fantastic time during the talent show. Not only did we have several musical performances, but people sharing with us what they are good at, and giving us “how to” demonstrations.
The spring 2019 PDC covered a wide range of topics and hopefully opened doors for its graduates to further pursue those topics. One of the main objectives of the course is that the graduates become better designers and hopefully better teachers of sustainable design. Those of us teaching the class get to make new friends, and support others in their efforts to create abundance through good design.

Pineapple Guava – Scientific Name: Feijoa sellowiana, Acca sellowiana
Written by: Kirby Fry
The pineapple guava is native to the tropics of South America but has naturalized in subtropical and sub temperate regions all around the world. It is a well shaped, evergreen bush or small tree with attractive flowers that grows 10 to 15 wide and just as tall. It can be used ornamentally and even be pruned into more formal appearing hedgerows.
A mature pineapple guava can tolerate freezes as low as 12 degrees Fahrenheit, but plants 3 years and younger can die back during freezing temperatures and should be protected with frost cloth for their first few years. The pineapple guava does very well in Central Texas cities where there is a “heat island” effect and along the Gulf Coast.
There are a few different varieties that are available such as ruby (red fleshed fruit), supreme (white fleshed fruit), Indonesian seedless, and crunchy white. These varieties are not always available in local nurseries though, and may need to be ordered from a catalogue or online.
The fruit varies in size and sweetness, and grows to be anywhere from an inch in length up to 3 or 4 inches in length. A young pineapple guava tree will produce half a bushel of fruit (4 gallons of dry fruit) by its third year. A mature tree will produce 3 or more bushels per year, or 24 gallons of dry weight fruit or more.
In Central Texas a pineapple guava will probably not achieve its full size and so can be planted 10 to 12 feet apart. It should be planted out of the way of freezing north western winds, and be given western shade. It likes well drained sandy loam soils with a little bit of clay in them.
Dig a hole twice the size of the container that it comes in and water it in well after planting. It needs a little extra water in the hottest time of the summer, usually two slow and deep waterings per week will suffice. Fertilize your pineapple guava with an organic form of nitrogen such as alfalfa meal during mid summer and early fall when it begins to flower. The fruit will begin to ripen mid fall.
Gradually prune your pineapple guava, removing branches growing straight out from the trunk less than 1 foot off of the ground. To shape it into a small tree remove the lower one third of the branches to encourage vertical growth. It can be pruned into a more formal hedgerow but more aggressive pruning will set back fruit production the following fruiting season.
The main pest for pineapple guava in Texas, mostly in the Rio Grande Valley, are root-knot nematodes, which can be addressed by adding organic matter fine mulch such as grass clippings) and compost over the plant’s roots.

A permablitz is an event where a group of volunteers works together to install a permaculture (permanent + agriculture) garden for a friend, a neighbor, a school, and/or a community garden. The garden can be an annual garden made for annual vegetables, or it can be a perennial garden made for fruit trees and other perennial food crops such as asparagus, brambles, and grapes.
A permablitz can also include installing a rainwater collection system, a gray water harvesting system, and/or building a chicken coop, trellis, or espalier.
How did we find out about permablitzes, and when did permablitzes get started here in Central Texas?
The permaculture community in Texas may have first learned about permablitzes from Dilek Wise, a graduate from a Permaculture Design Course that I helped teach with the Austin Permaculture Guild in 2011 or so. Dilek found out about an organization called Permablitz Melbourne, in Australia, that was helping their community to install permaculture gardens. Permablitz Melbourne had by then installed scores of gardens, and did a great job of documenting their work. They’ve also made some very helpful videos about how to run your own permablitz – a few are linked below.
When I learned about Permablitz Melbourne’s community effort working together to conserve soils and grow food locally, it reminded me of the work I had done as a US Peace Corps Volunteer in Guatemala. In the Highlands of Guatemala, north of Huehuetenango, we built and kept up 5 tree nurseries (each in a different village), implemented soil conservation methods, and planted woodlot trees in those villages, as well as 2 others. After getting out of the Peace Corps, it always seemed to me that we could and should be doing that kind of work here in Central Texas. Permablitz Melbourne demonstrated that indeed such a community effort was possible.
Then, during the winter of 2011, while I was helping to teach a class called Food Forests for All, at The Whole Life Learning Center, I shared with the students of that class what Permablitz Melbourne was up to. The students were enthusiastic and we had our first permablitz at Austin Ecoschool that very next January of 2012. Many of the people in that class have since had multiple permablitzes at their homesteads, and at community gardens that they were associated with.
Photos from our January 2019 Permablitz at the Multicultural Refugee Coalition’s New Leaf Farm
Since 2012 we have had well over 50 permablitzes, averaging about 9 per year, being held from September through May. In 2015 Earth Repair Corps was incorporated, in part, to help promote and run the permablitzes. If we have learned anything over the past 7 years, it is that we are not just building gardens, but communities that garden.
Since I was leading many of these events and heavily invested in them, there were at least six design elements that I tried to include in each and every permablitz.
- Soil and Water Conservation. As I’ve said during many of my talks and classes, soil and water conservation is the cornerstone of permaculture design – that which all else is built upon. Usually, whether we are planting trees or making annual gardens, we build some sort of earthworks on contour such as conservation terraces or raised annual garden beds. These earthworks serve to slow, spread, and sink surface water running off the garden site, make that water available to the plants in the garden, and catch any soil sediments and detritus that might also be running off of the site.
- Perennial Food Crops. Perennial food plants are the key stone of permaculture design – that which holds it up over time. A perennial food crop yields fruit, nuts, and berries year after year, unlike annual food crops that produce for 1 or 2 seasons and then have to be replanted. In Texas we have been planting mulberry, pomegranate, Asian persimmon, fig, apple, peach, plum, pear, pecan, pineapple guava asparagus, artichoke, grape vines, and blackberry brambles.
- Support Species of Plants. Another aspect of permaculture design that distinguishes it from organic farming is that we are creating agriculturally productive ecosystems, so not every plant we establish in a permaculture garden is a food crop. We use cover crops extensively, like clover, winter pea, rye grass, buck wheat, black eye pea, and millet to improve soils, and help vegetate bare soils. Farmers trees like black locust, acacia, golden ball lead tree, Eve’s necklace, and arroyo sweetwood are all native leguminous trees that offer dappled shade, have deep root systems that bring up minerals from subsoils, and many of which fix Nitrogen into soils. Lastly, deep-rooted herbs like comfrey, sorrel, and dock are added to some of our gardens for their soil-enhancing properties.
- Soil Amendments. Many of our soils in Texas have been eroded and do not have the available mineral content nor the organic matter in them available for agricultural crops to flourish. Bill Mollison was an advocate of adding soft rock minerals to soils to provide crops with needed elements, including soft rock phosphate, agricultural lime for calcium, pelletized sulfur, green sand for potassium and magnesium, and trace minerals. We also add a slow release organic fertilizer in the hole of every tree we plant which is inoculated with mycorrhizal fungi, and beneficial to the roots of most plants.
- Drip Irrigation. Fruit trees in Texas need supplemental water if they are going to flourish and be productive, even when they are perched on a berm just below a swale. The most efficient way to deliver this supplemental water is with drip irrigation. I have become a huge fan of Ewing Irrigation here in Central Texas. Each fruit tree needs about 4 gallons of supplemental water delivered to it every other day from May through early October, or for about 5 months.
- Mulch. At the base of each tree a heavy mulch should be applied annually. Wood chips from trees seems to be what is most readily available for us here in Texas, though if you look around to the north of Austin, from late spring through the summer, wheat straw is available. A good mulch cover will help to keep soil temperatures cooler than the ambient air temperature, suppress weeds, and slow down the evaporation of soil moisture which can be significant under the Texas sun and winds.

The costs for a permablitz can range anywhere from $700 to $4,000 and is usually paid for by the host site. A commitment from the host site is also needed to finish up any tasks that were not completed during the permablitz – finishing up the irrigation system seems to commonly be one of these tasks. The host site is also expected to provide volunteers with lunch during the work days.
Participating in a permablitz is a great way to meet like-minded people, learn more about sustainable design, and (after attending 3 permablitzes) have a permablitz at your home.
The permablitz schedule is announced on our calendar.
April 2019 – Crop of the Month
Peach – Scientific Name: Prunus persica
Written by: Kirby Fry
The peach is arguably the sweetest and tastiest fruit that can be grown here in Central Texas.
I have fond memories of preserving peaches with my cousins and aunts. We would blanche the peaches in boiling water for a minute or so, peel the skin off of the fruit, cut the peaches in half, remove the seed or pit, and then store the peach halves in quart sized Ball jars. Wonderful tasting peaches were on the menu for the rest of the year. At a birthday party, my favorite dessert is still peach cobbler.
The peach tree here in Central Texas, however, needs a little bit of extra care.
My first suggestion when cultivating peach trees is to not plant too many. It’s better to have half a dozen well-tended peach trees than it is to have a dozen poorly-tended trees. When we purchase and plant peach trees, we should keep in mind that this tree crop needs the attention that we give to annual vegetable gardens, not pecan groves.
My second suggestion is to be ready to replace and replant varieties that did not thrive. Peaches are a relatively short lived tree crop. We can expect 7 to 14 years of production from them. We can also expect quite a bit of pruning, and limb loss. Be prepared to replace some of the peach trees you originally planted with better varieties for your region that you later discover and learn about.
With a moderate amount of annual upkeep, though, peach trees can have high yields and are exceptionally rewarding. Some of the best peaches in North America are grown right here in Central Texas just west of the Balcones Escarpment in places like Fredericksburg and Stonewall.
Peach trees are available mid-winter in plant nurseries as bare root stock. The earlier they are planted the better – aim for late December to early January, as that gives them some extra time to establish their root systems. After purchase, they should be planted within 1 day or so upon arriving at your homestead. Avoid exposing the roots to air and sunlight by keeping them moist and wrapped in paper, or submerged in moist sand, and soak the roots in a bucket of water for at least an hour right before planting them.
Choosing the right variety of peach tree for your region is very important. Specific varieties of peach trees require a different number of chill hours in order for them to break their winter dormancy. Chill hours, are the number of hours per winter that the tree spends below 45 degrees Fahrenheit.
In the Dallas / Fort Worth area, there are between 900 to 1,000 chill hours, at the latitude of Austin there are around 600 chill hours, San Antonio may have 400 chill hours, and the Gulf Coast may have as few as 200 chill hours. So make sure that when you buy peach trees at your local nursery, the variety you are buying corresponds to the number of chill hours where you will be planting them. Texas A & M recommends Junegold, Juneprince and Southern Pearl for medium chill hour regions – 450 to 700 chill hours.
Select a site for your peach trees that is on sandy or loamy soils at least 18” deep, that is well drained, and which has good air circulation in order to reduce molds and fungi. The trees should be planted about 18 feet apart, and the rows they are planted in should be 24 feet apart from one another.
When planting a peach tree, dig your hole a few inches deeper than the root ball of the tree, and twice as wide. Add a slow release organic fertilizer with a mycorrhizal inoculant into the hole, and mix the same fertilizer into the soil that you will be using to back fill the hole with. Flood the hole with water before it is completely full of soil and make sure to get rid of all air pockets around the roots of the trees.
Cover a 2-foot radius area around your trees with 4 to 6 inches of mulch after planting them. Six weeks after planting the trees fertilize them with a 10-10-10 organic fertilizer.
Drip irrigation will be necessary from April through October depending on seasonal rainfall. Expect your peach trees to start making fruit around their 4th year.
Peaches make fruit on second year woody growth, so if you never prune a peach tree eventually the fruit will bear beyond your reach. It is recommended to initially prune the newly planted tree back to a single trunk, 2 to 3-feet above the ground.
The next winter prune the tree again, leaving only 3 to 5 of the healthiest branches that are evenly spaced out around its trunk.
Each year after that, 40 to 60 percent of new growth should be pruned back, leaving the center of the tree open. The tree should be sculpted it into the shape of a wine glass for good air circulation and exposure to sunlight.
Fruit buds need to also be removed in the early spring, establishing a spacing of 6 to 8-inches between fruit. A mature peach tree might put on 5,000 flowers and buds, when we actually want 500 or less fruiting buds.
There are a lot of insects and vermin out there that will want to eat your peaches. Deer-proof and rabbit-proof fencing are a good start for any orchard. Proper spacing and pruning will also go a long way towards keeping your peaches mold and fungus free.
Garden hygiene is always important as well. Manage weeds beneath your peach trees, keep a 2 to 4-foot radius around the trees mulched, and remove any fallen peaches quickly and compost them or feed them to livestock well away from your orchard.
The simplest treatment that I’ve come across for fighting insect infestation is the spraying of dormant oil on the peaches in mid to late January. It’s very important to completely cover the surface of each bud. Dormant oil is a horticultural oil with baking soda and dish soap in it that suppresses insect eggs from hatching by either smothering them or dissolving the waxy surface of the insect eggs. Once insects have begun hatching and sucking on the peaches the fruit becomes much more susceptible to fungal infection which can be spread from wound to wound by the insects. It’s an uphill battle after that.
Finally, late freezes may be what kills the most of your peaches. You can expect this at least every 6 or 7 years, and in some cases a late freeze might damage your peach crop 2 or 3 years in a row.
Be patient and observant. Buy a farmer’s almanac and start learning more about the chill hours in your region and what to expect each winter.
All of that said, I look forward to the late spring and summer harvest of peaches which is coming up in the next couple of months. I remember well my daughters and I stopping at the peach stands in Elgin where they were selling peaches from Fredericksburg, such sweet memories.
Earth Repair Corps is publishing a series of interviews with Permaculture Design Course graduates who have used the education & resources they gained from the course to further their careers in the world of sustainability.
Our hope is to convey what a life-changing opportunity the Permaculture Design Course can be, while learning more about what first attracted these former students to sustainable design and how they have applied those principles since taking a PDC. Learn More about the Permaculture Design Course and check out our upcoming Fall 2019 PDC.
We’re continuing this series with Jim O’Donnell of The City of Austin’s Wildland Conservation Division – read more below.
My degree is in education from The University of Texas. I was a teacher in Dripping Springs for 28 years. During the summer, I worked monitoring endangered species for different contractors. The Vireo Preserve in the 1980’s was home to the largest breeding population of Black-capped Vireos in Travis County. I was able to get the 214 acres of the Preserve set aside in 1989. So, we manage Vireo as endangered species habitat that also includes the addition of rare and unusual plant species.
For the past 10 years, I have been working for the city’s Wildland Conservation Division which manages 13,000+ acres to protect habitat for endangered species. I continue to monitor endangered species, but now with the addition of lots of restoration work. Volunteers are the key to our work and success. I love working with people who come out to Vireo to learn how to manage their land in a more regenerative way!
1. How did you become interested in sustainable design?
I grew up in the Bull Creek watershed in northwest Austin. As a teenager, I was able to hunt, fish, and camp in our Ashe juniper-oak woodlands. Even though the landscape had been dramatically altered by a history of clearcutting and overgrazing, there was still incredible beauty in this recovering system.
Observing our Hill Country landscape for over 50 years now, it is clear that some areas are so degraded that only a thoughtful and knowledgeable design can bring them back. Most land managers use fire and herbicide with the mistaken belief that the land requires such techniques.
Our approach on the City of Austin’s Vireo Preserve is to demonstrate that real regeneration begins with soil health, rehydrating hillsides, and adding diversity at all levels of the system.
We have been successful enough that we are beginning to apply our designs and techniques on to other properties within the City of Austin’s Balcones Canyonlands Preserve.
2. What were you looking to learn when you signed up for a permaculture design class?
Over the years, I have witnessed numerous re-vegetation projects that usually end in failure. I was intrigued with the permaculture design system that incorporated a holistic approach to interacting with the landscape to promote sustainability.
3. Who taught you your permaculture design course and when?
I finished my permaculture design course in 2014 at the Whole Life Learning Center. The instructors were Kirby Fry, Caroline Riley, and Taelor Monroe. I was very impressed with the instructors’ knowledge and commitment to earth repair and sustainability.
4. What other courses, if any, have you participated in to help you learn more about and implement sustainable design systems?
I have taken Elaine Ingham’s classes on soil biology.
5. Have you been able to apply what you have learned to your life and business?
I have been heavily influenced by the work of Dr. Elaine Ingham on how to build healthy soils. I am also collaborating with colleagues Dr. Brian Pickles and Monika Gorzelak, former graduate students of Dr. Suzanne Simard (University of British Columbia), to investigate the role of fungal networks in distributing resources among plants within forest ecosystems (“world wood web”). I am also supporting research by Dr. Moriah Sandy (University of Texas at Austin) on potential medicinal and ecological properties of endophytes on Ashe junipers. All of this research supports further knowledge on how to build regenerative ecosystems.

6. Have you had the opportunity to teach, mentor, or pass on information about sustainable design?
I have had the opportunity to work closely with several area Master Naturalist chapters to teach about design. The Capital Area Master Naturalists have been extremely helpful in recruiting volunteers for our project and giving us a platform to speak at presentations. I’ve also been a guest speaker at St. Edwards University and recently at the University of Texas. I am very excited to be a speaker at the Global Earth Repair Symposium in Port Townsend, Washington, in May. And finally, I want to express my deep appreciation to the local permaculture groups for all the knowledge that they impart, their good work, and dedication to community.
