ERC Permablitz Garden Monitoring and Maintenance Program
2015.08.17 | Report by Michelle Hernandez
The gardens are doing well and producing in this summer heat.
Irrigation System: 2 separate systems of drip line on timers, run for 1 hour every other day early in the morning. The 2 systems run in alternating days. As a very rough estimate of water usage, we use 461 gallons of water to run all the berms. (length of berms x # of drip lines x distance of emitters on drip lines x emitter rate/hour). Read More
Purpose: To create a perennial food storage system for human/poultry/bee forage.
Private or Public land: Private (Residential)
Original Installation Date: 2015.03.14,15
Original Budget: $1350
Funding Provided By: Property owners
Site Liaison(s): Michelle Hernandez (property owner)
Volunteer Information: Approximately 34 volunteers helped with this permablitz.
How long did the install take?: 9-5, two days
What has worked well:
- Having drip irrigation on a scheduled basis. We had to replace one of the drip irrigation timers for failure for unknown reason. Otherwise, the drip irrigation has worked well.
- Using plenty of compost and plenty of mulch.
- Densely planting cover crops and other smaller plants.
- Regularly visiting the earthworks and harvesting crops (and just enjoying observing nature). Also pulling weeds when they are small.
What hasn’t worked so well and presents learning opportunities:
- Weed growth, especially on one specific berm. I think the issue was the mulch and compost was thinner on that berm in area 13. Less cover crops came in, and weeds moved in. The soil will need to be improved over time.
- Loss of trees. The section below will outline what trees were lost where. They primarily were lost on the berm in area 13 and also were primarily red buds, although there were some other nitrogen fixers lost. Some of these red buds had been in pots for multiple months, but the pots were “staggered” (?) pots. (I don’t know what they are called.)
- The “invisible” deer fencing. The bottom fishing line has been unraveled multiple times (maybe by my dogs). Deer or other wildlife eats plants that aren’t either large enough or are deer resistant. My strategy will be to plant deer resistant plants.
What needs to happen to keep the garden vital and productive:
- Feeding the soil
- Consistent water, compost, and mulch monitoring and replenishment when needed
- Variety of plants with different functions and nutrient profiles
|Irrigation||How is the Garden Getting Water?||Two separate systems of drip line on timers, run for one hour every other day in the morning. The two systems run in alternating days.|
|Estimated Water Use||As a very rough estimate, we use 461 gallons of water to run all the berms (length of berm x # of drip lines x distanve of emitters on drip lines x emitter rate/hour)|
|Earthworks||Soil Type/Composition||Soil type/compositions – mix heavy clay soil (black gumbo clay) + berm builder + soil from existing raised wooden beds in garden.|
|Soil Depth||1 foot above ground created by Permablitz|
|Number of Berms/Swales Installed||5 (in 3 different areas: “area 3”, “area 12”-shaded, and “area 13”)|
|Length/Width of Berms and Swales in Linear Feet||Total: 173 linear feet of berm, 173 linear feet of swaleBerm/Swale 3c: 6’x27’
Berm/Swale 3b: 6’x22’
Berm/Swale 3a: 6’x19’
Berm/Swale area 12 (in shade): 8’x50’
Berm/Swale area 13: 8’x55’
|Was Soil Imported? If So, How Much?||6 yards (could have gotten away with 5)|
|Was Mulch Imported? If So, How Much?||Mulch was imported, I guess. It came from neighbor’s wood-chipped dead oaks (sat for over 1 year) + tree trimming service for public utilities. All free. Don’t know quantity.|
|Plants||Number of Trees Planted||24|
|Species/Spacing Between Trees||Berm 3c trees: Common Persimmon, Red Mulberry, Texas Persimmon, PomegranateBerm 3b trees: Loquat, Anna Apple, Kidneywood, Blushing Delight Apple, Moringa
