Scutellaria ovata/Heartleaf Skullcap and its subspecies
Family:  Lamiaceae/Mint  

The delicate blue flowers of Heartleaf Skullcap provide a refreshing sight in late spring and into summer. Their bloom time compliments well in the landscape with other wildflowers that stop blooming sooner, and this overlap helps to provide food for pollinators throughout the summer.  When happy, these reliable perennial herbs spread quickly into large stands through their rhizomes, like many other species in the mint family. They are easy to propagate by digging and replanting the roots, and though they can spread into large clumps, they are not particularly aggressive when growing with other plants. Heartleaf Skullcap is one of various Scutellari species that grow in Texas, and prefers slightly more moisture, soil, and shade than the average hill country plant to truly thrive.

Yet, they are still very hardy and can survive a drought even in poor/shallow soil once established, though their growth will be reduced in those conditions. In deeper soils, Heartleaf Skullcap can more easily thrive in full sun, and it often prefers well-draining soils over heavy clays. 
This wonderful woodland edge plant follows a cool season life cycle, and in fall it will begin growing out many different stalks from its roots, which then maintain themselves as a low groundcover over the winter. This growing habit is very useful to incorporate with warm season plants that go dormant in the winter, so that both groundcover and photosynthesis/feeding of soil microbes can be maintained over the winter.

Heartleaf Skullcap starts to grow its stalks out in early spring, reaching anywhere from 1-3 feet in height before they bloom, depending on their growing conditions. Depending on latitude, light, and moisture conditions, they usually begin to bloom anywhere from April to May, continuing into summer, and will continue blooming longer with wetter conditions. Heartleaf Skullcap loves the cool weather, and typically goes dormant as the summer heat settles in, unless prolonged by cooler weather and periodic rains, or if growing in a cooler and moist microclimate.

Scutellaria ovata is becoming more common in nurseries thanks to its various beneficial qualities and growing habits. The beautiful silvery-blue-green, fuzzy foliage and soft blue blooms create a pleasant visual contrast in the landscape. Like many other Scutellaria species, Heartleaf Skullcap also possesses useful medicinal compounds, and can be used similarly to Scutellaria lateriflora, though they have their differences.

Penstemon/Beardtongue species
Pictured: Penstemon cobaea, Penstemon triflorus, Penstemon baccharifolius, Penstemon tenuis
Family: Plantaginaceae (Plantain) 

The Penstemon genus features many different species of small perennial herbs with a great variety of striking flower colors and shapes. These are typically perennial plants that send out a 1-2 foot stalk when they bloom in the spring or summer, and remain a small, unimposing rosette for much of the rest of the year.
Their dense growth of trumpet-shaped flowers makes them an excellent early spring food source for hummingbirds, and a delight for all who long to be drawn out of the dull colors of winter. Many species re-seed easily, and though they are not aggressive, they can spread into large vibrant patches when allowed. Extra moisture and afternoon shade will help extend the bloom time of these fleeting flowers, but western species must have good drainage.

There are multiple Penstemons that love to grow in every ecoregion and habitat condition across Texas, from dry western canyons to eastern and gulf coast marshes and swamps. They are adapted to a wide variety of difficult Texas soil types, and one species, Penstemon triflorus, is endemic to the Edwards Plateau and its surrounding areas.
When we grow and propagate increasingly uncommon native plants like these, we help restore genetic diversity and mitigate the current fragmentation of their populations, some of which are very isolated. Thankfully, in recent years Beardtongue species have become easier to find in the nursery trade, especially at specialty native plant sales.

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.

                       How to run a permablitz?

                       Permablitz on Costa’s Garden Odyssey, 2009

                       Plug In TV – Permablitz

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.

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.

Photos from our September 2018 Permablitz at Proffitt Ranch in Marble Falls, TX

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.  

Explosive abundance!

April 2019 – Crop of the Month
Peach – Scientific Name: Prunus persica
Family: Rosaceae
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.

Variety Selection

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.

Planting Tips

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.

Pruning Tips

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.

Pest Management

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.


About Jim

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.

March 2019 – Native Plant of the Month

Tinantia anomala – False Dayflower
Family: Commelinaceae

False Dayflower is a delicate perennial herb native to central Texas that loves to grow in the forest understory, in woodland meadows, slopes and edges, and in riparian areas and their margins. It grows very well in the rich soils made by the leaf litter of trees but is hardy and adapted to the various kinds of rocky limestone soils common in central Texas. They like to have some extra shade and moisture, but are also highly drought tolerant once established in a suitable spot.

Tinantia anomala will grow out its fine, grass-like leaves from fall through winter, eventually sending out stalks that can reach a height of up 1-2 feet, and then the small purple blooms begin to brighten the forest floor, usually starting around mid-March. This herb prefers growing during the cool season and will often go dormant once summer heat sets in. Tinantia’s cool season growth habit complements that of the warm season plants that emerge later, helping to maintain photosynthesizing plants and their roots in contact with the soil for longer.

While the most common flower colors seen are the varying shades of purple, they also occur in white and blue. Their soft flowers sprinkle the awakening forest floor with a soothing display, along with the blooms of many other small herbs of similar habit that Tinantia is fond of growing with, such as: Baby Blue Eyes/Nemophila phacelioides, Golden Groundsel/Packera obovata, Heartleaf Nettle/Urtica chamaedryoides, and the related Spiderworts/Tradescantia and Dayflowers/Commelina species.

Tinantia makes a wonderful groundcover, quickly spreading through its rhizomes to send out new shoots. One small transplant can easily spread over a foot or more in one year without any nurturing beyond choosing a good spot. At the same time, it is a gentle plant that does not tend to overtake gardens, and is easily pruned if overgrown. It grows easily from seeds as well. False Dayflower is an excellent choice for habitat restoration projects where hardy plants that can reliably succeed from transplant without extra care are able to be utilized.

The finer, fibrous part of their root systems interweaves gracefully with the varied root structures of other plants to create greater structural complexity in the soil. Tinantia‘s roots, though delicate, are still wonderful at holding soil together and spreading to stabilize loose soils. Tinantia anomala is another wonderful native plant we can easily incorporate into landscapes to increase biodiversity and provide early season pollinator and wildlife forage.

Apple – Scientific Name: Malus pumila
Family: Rosaceae
Written by: Kirby Fry

A favorite fruit for many people is the apple.  It is a firm, crisp fruit that is delicious when eaten raw, it stores well, and it can be cooked into many of our favorite deserts.  Not only are apples tasty but they are also good for us.  I remember my grandmother repeating the common phrase “an apple a day keeps the doctor away.”  Apples are high in vitamin C and fiber, and low in calories and sodium.  Eating an apple before going to bed is also a good way to clean your teeth.

Apple trees should be purchased in January or February as 1-year-old bare root whips that are 2 to 3 feet tall.  They should be planted in late winter or early spring.  Buying a younger tree with a healthier root system is a much safer bet for growing a healthy tree than buying a 2 or 3-year-old tree with a poorly developed root system. 

Apple trees, like other fruit trees in the Rosaceae family (peaches and plums in particular), require a higher degree of feeding, pruning, and plague prevention.  So, if you want a healthy productive apple tree then be prepared to do more pruning, bud thinning, fertilizing, and plague prevention than you would otherwise need to perform for fig, loquat, and mulberry.

Planting Requirements

Choose an area for your apple trees that has well drained soil, has some protection from strong winds, and gets at least a half day of full sunshine as the fruit needs sunshine to ripen – afternoon shade is best if the tree is not in full sun.  Apples are cold hardy and need different amounts of chilling hours to produce their fruit.  The more chilling hours a region has the greater variety of apples we can choose from.

Choose the proper varieties for your region.  The further south we are in Texas, the fewer chilling hours we have and so the number of apple varieties that do well in these low chill areas are few – the Dorsett Gold and Anna varieties are recommended for the Gulf Coast and Rio Grande Valley areas.  Apples need at least 2 varieties to be planted close together for cross pollination, so at least one Dorsett Gold and one Anna should be planted together.

Varieties that do well in Central Texas are Jersey Mac, Adina, Gala, Mollie’s Delicious, Starkrimson Red Delicious, Braeburn, Granny Smith, Pink Lady, Anna, and Dorsett Gold.  Harvest fruit early to mid-June.

Varieties that do well north of Central Texas are Jersey Mac, Adina, Gala, Mollie’s Delicious, Ozark Gold, Starkrimson Red Delicious, Golden Delicious, Braeburn, Fuji, Granny Smith, and Pink Lady.

The apples requiring fewer chilling hours will ripen first in early to mid-June, and the apples requiring the more chilling hours will ripen as late as late September to early October.

Dig a 3’ wide 3’ deep hole for your apple trees to be planted in.  Plant the tree to a depth just below lowest graft.  Soak the trees in water for at least 1 hour before planting.  Set the tree into your hole and then add alternating 2” layers of soil and compost into the hole.  Before filling the hole completely, flood it with water to eliminate all air pockets.

Fertilization and Maintenance

Spread a 2” layer of compost around the tree after it has been planted, then once a month for 3 months add 1 cup of a high nitrogen organic fertilizer such as alfalfa meal.  The next year add 2 cups of fertilizer once a month for 3 months beginning in the early spring, and during the third year add 3 cups of fertilizer once a month for 3 months.  Once the tree is established add 1 pound of fertilizer for every 1” in diameter of the tree, once in the early spring and then once again in May.

Your apple trees will need 1” of water on them every 4 to 5 days for the first month after they are planted, watering should then occur with frequencies further and further apart until the trees need just one good watering every 2 weeks through the summer.

Pruning an apple tree during its first 4 years of growth is important.  Many planting guides recommend pruning in the middle of winter while a few others recommend pruning mid-summer.  Experiment and observe, and be ready to act if and when you notice a blackening around pruned areas.  When pruning, leave the healthiest looking branches that are spaced out evenly, then trim back those branches to a quarter of their original length.  Do not over prune in any single year as it exposes too much of the vascular system to infection and a loss of sap pressure, be moderate and consistent.

As the tree begins to set buds, remove all but one bud per cluster of buds, with the remaining buds being spaced out about 6” apart.

There are quite a few apple diseases that we need to be on the lookout for including scab, cedar apple rust, fireblight, blotch, and bitter rot.  Possible insect plagues include spider mites, plum curculio, aphids, and coddling moth.

A paragraph about each one of these plagues could be written.  Good garden hygiene is important – like removing fallen apples and infected leaves from under your trees and keeping the tree’s canopy open to air and sunlight.  Maintaining the soil’s health under the tree is also helpful in resisting plagues.  A couple of products that I have heard recommended by organic growers are neem oils that can be sprayed on apple trees to resist fungal blights and kaolin clays that can be sprayed to help resist insect damage.

Harvest your apples as they become fully ripe and they will taste better and store longer.  Share them with friends, take them to market, and brush up on how to preserve and store them.  Explosive abundance!

Read our 2015 post on Festival Beach here

Three years after the design and installation of the Festival Beach Food Forest in Austin, Texas, Woody Welch and I had the pleasure of revisiting this amazing parkland food forest.  The trees and plants were doing exceptionally well, a wheel chair accessible decomposed granite walkway has since been added, along with several other mulched paths and park benches.  Woody got his drone in the air and was able to take some amazing shots of the site showing just how close the food forest is to the center of Austin, Texas.

  1. In late October of 2015, Earth Repair Corps partnered with Festival Beach Food Forest and Tree Folks to assist with the installation of a food forest in a public, highly-visible green space just north of Lady Bird Lake and east of Interstate Highway 35 right in the heart of growing Austin, Texas.

  1. The Festival Beach Food Forest team, Pete VanDyck, and I spent days surveying this site with laser levels and landscaping flags. First, we found the lowest spot on the site and then marked contour lines every 6” and up from there in elevation. What was revealed by that survey was that the park is shaped like a shallow bowl with a large drain passing through the middle of it that drains almost all of the water from Festival Beach Community Gardens and the apartment complex parking lot adjacent to the community gardens.

  1. Three conservation terraces were installed above and out of the way of the drainage system, 2 on the north side of the food forest and 1 on the south side. A tree boomerang / berm was built up with Geo Grower’s “berm builder” soil around one of the prominent live oaks, and 2 large berms were built up with the same material along the park’s perimeter that would eventually shield the site when planted from the automobile traffic along IH 35.

  1. Here is a good aerial shot of the Festival Beach Food Forest. Festival Beach Community Garden is right next door to the food forest.

  1. During this most recent visit, I thought that one of the most successful design elements was the hedge row planted on the perimeter berms. The Arizona cypress trees, and sable palms (both evergreens) had at least tripled in their size, and in just three years were doing a really great job of sheltering the park from the interstate highway.

  1. Another one of my favorite elements is the fruiting calendar that was planted on the longest terrace on the south east side of the park. If you’re standing in the center of the food forest and looking at the terrace, from left to right you will see – loquat, mulberry, peach, plum, apple, pear, pomegranate, and Asian persimmon. That is the same order that they will fruit throughout the calendar year.

  1. A new addition to the food forest since the original planting, olive trees.

  1. Underneath the live oak tree with the tree boomerang below it, I noticed a lot of beautiful native Texas plants had been established. Here is a shot of one of my favorites, sweet almond verbena.

  1. Also in full bloom, not too far from the sweet almond verbena were several loquat trees. I don’t think that I’ve ever really experienced the fragrance of loquat flowers before, they smelled wonderful. The loquats’ flowers had sure gotten the attention of the honey bees on this warm sunny winter day.

  1. The visual rock stars of the food forest were the arroyo sweet wood trees which were still holding on to their fall leaves.

Elymus/Wildrye genus  – Prairie/Canada Wildrye and Virginia Wildrye – Elymus canadensis and Elymus virginicus, etc.
Family: Poaceae

Elymus is an agriculturally and ecologically important genus of mid-size cool season perennial bunchgrasses, and many different species are found in a variety of habitats throughout Texas. Cool season grasses grow starting in fall and winter, when the warm season grasses are beginning to go dormant. Elymus canadensis (featured in the pictures) and Elymus virginicus are two of the most common species that are fairly widespread across the state. While these two species are generally distinguished by their drooping (canadensis) vs upright (virginicus) seed culms, Elymus species may also have multiple varieties that occur within them (as with canadensis), have been found to hybridize, or have been said to be simply different forms within the same species (Guide to Texas Grasses – Robert B. Shaw).

In Central Texas, the versatile Wildryes are frequently found growing in shade or sun along lowland and upland riparian areas, woodland edges, meadows, prairies, forests, etc., with quite a bit of variability between all the species as to preferred moisture and sun conditions. Though they love to grow in the moist and deep soils and creek banks, they aren’t actually too picky when planted elsewhere. Even within one species, such as Prairie Wildrye/Elymus canadensis, some stands are happy in full sun when they have enough soil and moisture, and many others love to grow in the shaded understory of large trees, especially if they are in shallower soils or further from water.

Elymus species are very hardy grasses that are still common and somewhat abundant in the wild compared to many other native cool season forage plants. Their habit is to go dormant in dry summers unless they are in a moist area, but these grasses will otherwise have green growth for much of the year. Cool and moist conditions at the end of spring will prolong their growth into summer before going dormant.

They are important forage grasses that reliably provide food for wildlife, livestock, and soil microorganisms during winter when green forage is otherwise scarce. These grasses are generally grazed in rotational systems from fall through spring, but then avoided after their long seed culms go to seed at the start of summer, as these seed culms are said to be potentially problematic to livestock due to possible fungal growth. But while the livestock avoid it, the thatch and seeds they produce will be used by wildlife for nesting material and food.

This clump of Elymus canadensis is being grazed by wildlife in December.

Wildryes are also an excellent grass to use for pasture re-vegetation and habitat restoration projects, since their seeds are easy to find, collect, and germinate, even in poor soils. Their seeds establish exceptionally well and quickly compared to many other native grasses, and love shade or sun. Elymus stands can be very prolific in combination with deciduous forests that protect them in summer and then let the sunlight through in winter. Wildrye species are all-around great for improving degraded habitat conditions by revitalizing disturbed soils and bridging the temporal fragmentation of food sources that is exacerbated by low species diversity.

January 2019 – Crop of the Month
Mulberry – Scientific Name: Morus rubra
Family: Moraceae
Written by: Kirby Fry

Winter is upon us here in Central Texas and most of our favorite nurseries are now getting in their bare root, fruit tree stock.  These trees are cultivated and grown in loose sandy soils on larger farms and then removed from that soil and shipped out to our local plant nurseries with no soil around their roots and no containers.  At the local nurseries they are “banked” in a pile of sand until they are purchased and taken home by customers.  They are usually then wrapped in wet paper and kept out of direct sunlight until they are planted in the ground.

Not having to grow out these fruit trees at the nurseries themselves lowers their cost, usually by half, but the time window of their availability is narrow (from early January to late February) and often you need to order these trees in October to secure them because when they arrive at the nurseries they sell out quickly or in many cases have already been pre-sold.  Many tree farms will direct ship to your home as well.  So get your orders in early, or be ready to act quickly and buy them up as soon as they arrive at a local nursery.

This winter we will be featuring three fruit trees that are available as bare root stock – mulberry, apple, and peach.  Grape, blackberry, and asparagus are also available as root stock this time of year.  So get your gardening game on!

– Planting Tips – 

Let’s begin with the mulberry tree.  It produces a small reddish purple ¾” to 1 ¼” long fruit.  If you enjoy watching birds, mulberries are a real treat.  When the trees are fruiting in the spring there is no need to go out bird watching because all of the local birds will be coming to your mulberry trees.  Every spring I get to observe the latest families of wood pecker and tufted titmouse pass through my small mulberry orchard almost on an hourly basis for several weeks.

There is a variety of mulberry tree, Morus rubra, which is native to the Eastern United States.  Many mulberry varieties can become invasive because birds love them so much and spread their seeds, so in this blog we will stick with a variety that is native.  Mulberries are very fast growing for the first 10 or 15 years of their life and then slow down as they mature.  They may serve as an effective means of erosion control, and wind break.  Most mulberries grow to a height of about 30 feet, but the native red mulberry in the right conditions can get up to 70 feet tall, though I’ve never seen one this tall.

They prefer rich well drained soil and full sun, but will thrive in partly shaded areas as well.  Mulberry trees should be planted no closer than 15 feet apart.  Choose a location for your mulberries that is well away from sidewalks and driveways, as this fruit tree makes a lot of fruit and attracts many birds and can be quite messy below its canopy.  Like most fruit trees, when we plant them, the hole we dig should be at least twice the size of the root ball.  Since we are talking about bare root stock, there is no container nor any other soil that we need to address.

A slow release organic fertilizer and minerals should be put into the hole before the tree is set down into it.  I like Bio-tone’s plant starter mix that has a mycorrhiza fungal inoculate in it as well as organic fertilizers.  I also like to add ag lime (Ca), pelletized Sulfur (S), green sand (K, Mg), soft rock phosphate (P), and trace minerals.  This mix of fertilizer and minerals should also be added to and stirred into the soil that is going back into the hole, as well as put into the bottom of the hole before planting.

Mulberries require minimal pruning, but pruning should start when the tree is small and the branches are less than 2 inches in diameter.  Pruning is used to establish a set of main lateral branches and prevent the crossing and rubbing of branches, to manage the tree’s height and make harvesting easier.

The mulberry tree is extremely tough and does exceptionally well in our climate requiring very little watering and pest management.  An annual mulching of the ground beneath the tree’s canopy might be all you ever need to do to keep this tree thriving.

Visit your local nursery this week and check out their incoming supply of bare root fruit trees!
