Teaching Garden Update: Caterpillar Strikes Gold

4/29/2021

Comments

 
Picture
I captured this caterpillar chilling on golden oysters growing at Zilker Botanical Garden in our strawberry and asparagus, mushroom garden bed.

I did a quick iNaturalist search to learn it is a Salt Marsh Moth, Estigmene acrea. This app is a great tool for researching and identifying good and bad insects. You can see multiple pictures of insects at their various stages of life, and descriptions from Wikipedia. It even gives you a breakdown of where else insects have been observed in your area on a map.
The caterpillar is beautiful as a moth, and as a growing caterpillar clearly had an appetite for nitrogen rich vegetables. They were also devouring the leaves of the fava beans that were nearby. We contemplated why one of the caterpillars was a fungivore. Definitely has good tastes. This lucky caterpillar struck gold in finding an even more appetizing meal. We decided to allow these caterpillars to continue to enjoy their meal.

Learn more about how to grow mushrooms in the garden here.

From Texas A&M:
Despite the name, salt marsh caterpillars can show up in many different habitats other than salt marshes. They eat a wide variety of plants and are found all across the United States. In some places, like southwest United States, these caterpillars can damage crops. Salt marsh caterpillars skeletonize the plants they feed on, leaving only the main leaf veins. Older caterpillars eat large holes in the leaves and become more solitary. They can go great distances in search for food and can sometimes travel in large numbers.

Salt marsh caterpillars do not bite and are not poisonous.

We just passed the Full Pink Super Moon, theSprouting Grass Moon, the Egg Moon, the Fish Moon, the Paschal Moon, Hanuman Jayanti, Bak Poya, and a Supermoon. So many interpretations of the full moon around the world.

We are now going into a waning period of the Moon—from the day after it is full to the day before it is new again. As the moonlight decreases night by night, plants are encouraged to grow roots, tubers, and bulbs. It’s always best to try to plant with the coming rains which are in the forecast. 
Click on the links to get growing information and best varieties from Texas A&M Extension and other sources. 
ROOT CROPS
Sweet Potatoes (Slips)


GROW YOUR OWN 

You can plant sweet potato slips through June so you still have a little time to grow your own slips at home. See our blog post on two ways to do this at home. The method that produced the most slips was the “soil method.”  There were approximately 25 slips created from one sweet potato.

SLIP GIVEAWAY
We have so many purple sweet potato slips left over from the soil method that we decided to do a give-away. The first person to respond to our email by April 28, 2021, with the correct answer to the following question wins!
What family is the Sweet Potato in?
Pick-up is in Central East Austin (78702).

WHERE TO BUY

If you haven’t grown your own slips you can buy them at local nurseries such as The Natural Gardener and Tillery Plant Company. You can even plant small organic sweet potatoes directly in the soil.

Unwanted Visitor at the Teaching Beds at Zilker Botanical Garden

4/26/2021

Comments

 
Picture
This past Saturday we found a green, spotted caterpillar that was devouring one of our sungold tomatoes at the teaching gardens Zilker Botanical Garden. 

Caterpillars like this and the tomato hornworm, can be a major pest in gardens.They also feed on other plants in the Solanaceae (nightshade) family: eggplants, peppers, tobacco, and potatoes. They blend in quite easily with the green foliage and feed non-stop, creating spotty and chewed leaves and fruit

HOW TO GET RID OF TOMATO WORMS
👌Handpicking - The caterpillars can neither sting nor bite. If you are squeamish about crushing these large insects, drop them into soapy water instead (or feed them to your chickens.)

🧼Insecticidal soaps will also kill hornworms, but the pests need to come into direct contact with the substance.

🌻Increase Plant Diversity: Plant crops that attract natural predators of caterpillars such as wasps, lacewings, birds, lady bug beetles, and spiders. Plant things like sunflowers, marigolds, buckwheat and mulch with straw or leaf mulch to give a home for these insects in your garden.

🐛Insecticides should be a last resort. You can use the organic pesticide Bt (Bacillus thuringiensis), which is a bacterium that acts as a stomach poison on some larval insects (but doesn’t harm other plants or animals). Bt must be ingested by the caterpillars to be effective, and it must be reapplied to plant foliage after rain.

We just passed the first quarter and the moon is now in waxing gibbous going into a full moon. Now is also a time to seed-in plants that fruit and seed like beans, corn, cucumbers, watermelon, cantaloupe, pumpkins, squash, okra, and southern peas. Their is still time for transplants of strawberries, eggplants, tomatillos, tomatoes and peppers. Also time to plant nut and fruit trees including citrus, and berry bushes and grape vines. It’s always best to try to transplant and seed-in with the coming rains. Which is coming this week.

DIRECT SEED
  • Beans (Pole, Snap and Lima)
  • Cantaloupe
  • Corn
  • Cucumbers
  • Okra
  • Peas (Southern)
  • Pumpkin
  • Squash (Summer & Winter)
  • Watermelon
Many of the varieties of seeds are associated with the three sisters or milpa agriculture system we learned about in March with our special guest Sam Dixza Rugs & Organic Farm from Oaxaca, Mexico.

This is your last chance to plant corn until late summer.

For this year's three sisters at Zilker Botanical Garden, we planted heirloom, glass gem corn with Royal Burgundy pole beans, and tatume squash. The squash will start to vine out and protect the soil as the heat increases. Around the perimeter we planted Oaxaca Red Epazote (thanks for the donation Danielle), Habanero Lemon peppers (thanks
Sunshine Community Gardens), Hopi Black Dye Sunflowers and Mexican Marigolds.

TRANSPLANT
  • Eggplant
  • Ground Cherries
  • Peppers
  • Tomatoes

Refreshing Raised Bed Soils Using Sunshine Community Garden’s Custom Recipe

4/19/2021

Comments

 
Picture
In this video Charlotte from the SCG Education Team gives a breakdown of Sunshine Community Garden’s custom recipe for refreshing raised bed soil that has been depleted or sitting without proper protection from the Texas heat. This volunteer project by members of the Sunshine Community Gardens was at the Texas School for the Blind and Visually Impaired Garden which is also located at Sunshine. This soil refresh recipe is perfect for school or community garden beds, container gardens, or any raised beds that have been sitting unused for a period of time. Many of these tips apply to all soil amending in central Texas, even for in ground beds. 
​
PLANNING
  1. All stages of this work require a dust mask and gloves for all workers.
  2. Think in terms of the volume of “spent” old soil mix to new mix. Aiming for a ratio of 50:50 is a good rule of thumb but you can vary this by your situation and budget. Try for at least 2/3rd of the old soil mix to 1/3rd amended mix.
  3. A good portion of the renewal mix should be a good quality compost, whether purchased or homemade, since this is the best resource for the new “living” components of your renewal mix. The kelp meal we use in this recipe provides food for our renewed soil’s living community.
  4. If worms are encountered at any time during the process, carefully set them aside in a good amount of moist soil to protect them from the “mixing” steps. Gently reintroduce them to the refreshed bedding mix after it has been returned to the box or raised bed.
  5. A bed that is going to rest for a season is built slightly differently than one that you are going to use right away. You do not want excessive compost activity to compete for nitrogen during your plant’s growth stage, especially the green growth prior to the fruit setting stage, so you may need to add your favorite more immediately available amendments near new plants so that they neither compete, nor wait, for slower releasing components. 
  6. Prior to mycorrhizal reformation in the soil, which will take some weeks, your transplants may need more water too since these networks must form to extend your plant root’s “water reach” and improve drought tolerance.
  7. These mycorrhizal networks are part of your “soil food web” which needs time to establish following all of the mixing disturbance of this refresh method. These networks will regenerate and establish their symbiotic relationship with your plant roots becoming their nutrient and water “help mates.”  
  8. Refreshing raised beds is also possible using “lasagna” (or similar) no till methods by adding refreshed layers regularly each season. This will be covered in a future video.

RECIPE
The following is Sunshines Community Garden’s custom soil refresher recipe. It does not require precision and the amounts are approximate.

Major components
6 – 10 parts        spent (previous/old) old bedding mix
4 - 5 parts            compost
1 part            rice hulls (premoistened)
1 part            shredded coconut coir (premoistened overnight if possible)
½ part             kelp meal (i.e., use ½ to all of a 5lb box from Down To Earth)
½ part             perlite (optional, i.e., use ½ to all of an 8-quart bag) 
½ part            diatomaceous earth (optional)

Mineral Amendments
Add by the cup or by the handful. Use product packaging or the internet for reference:
  • Green sand – very slow release micro mineral
  • Azomite – very slow release micro mineral (or get the powder for faster release)
  • Sulfur pellets – slow release acidifier
  • Magnesium Sulfate (Epsom Salt) – rapid release – makes calcium available 

Optional Amendments 
Best added on top of refreshed soil for more immediate availability:
  • Worm castings
  • Seaweed spray
  • Fish emulsion spray
  • A balanced, gentle “N-P-K” meal or granules: Down to Earth or Jobe’s 

BREAKDOWN IN STEPS
STEP 1:
On a tarp, remove old soil from beds into piles of around one-fourth cubic yard each (30-40 gallons) to make mixing easier. In the video we give a suggestion for cases when it is not possible to amend all of the old soil by inserting the compostable layer (normally at the bottom of a raised bed) above any soil that will not be amended. Amend 100% of shallow beds but 50-70% of deeper beds is fine if you have time or budget limitations.

STEP 2: Next to the pile of old bedding mix, start with a separate pile, with compost, close to the same size (20-30 gallons.) Any type of organic compost works and we chose to use turkey compost. 

STEP 3: Add a significant amount of nitrogen-rich structural amendments that will break down more QUICKLY (in 1-2 seasons.) These types of organic matter are often agricultural by-products and can be free or inexpensive. Follow our recipe, product packaging or internet to determine the amount to add.

While certain amendments (like rice hulls, coconut coir or diatomaceous earth) are best pre-moistened before adding them, it is easier to mix your piles if everything is drier. 
  • RICE HULLS – A combination of structure (temporary in hot climates) & nutrients including silica. Silica strengthens cell walls, guards against environmental stress, improves the uptake of water and minerals and adds an extra level of protection against diseases like powdery mildew.
  • COTTONSEED MEAL  –  Cottonseed meal feeds nitrogen, potash, phosphorus, and other micronutrients over a period of time, eliminating runoff, and promoting vigorous growth
  • DIATOMACEOUS EARTH (DE)  –  Water retention and reduces amendment leeching. (See section at the end on amendments that can be confusing.)
  • SPENT MUSHROOM BLOCKS  – A waste product from growing culinary mushrooms. The blocks, composed of sawdust and grains, are colonized with mycelium which is high in nitrogen, carbon, phosphorus and trace minerals. It will increase the water-holding capacity of the soil. To get mushroom compost blocks for your garden, sign up here.
  • COFFEE CHAFF  –  A waste product of the coffee bean roasting process. Coffee chaff wards off harmful slugs and snails. Coffee chaff adds helpful nutrients, like nitrogen. On the other hand, brewed coffee grounds require nitrogen to breakdown in the soil so do not use brewed grounds as a structural element in refreshing soil. (See section at the end on amendments that can be confusing.)
  • KELP MEAL – Seaweed or Kelp Meal adds potassium (K), trace minerals, salts, alkalinizing the soil. It's an excellent bioactivator, waking the microbes in the soil to help break down organic matter. Add kelp meal at this “significant volume” but quicker break down stage, if using:

STEP 4: Add a significant amount of structural amendments that break down SLOWLY such as coco coir, peat moss, perlite and vermiculite. Follow our recipe, product packaging or internet to determine the amount to add. 
  • COCO COIR – Coconut Coir is a natural fibre extracted from the outer husk of coconut and has a neutral pH range of 5.2–6.8. 
  • PEAT MOSS – Peat takes millennia to generate, and bogs store 10 times more carbon than forests. Coco coir is more sustainable but needs to be shipped from a distance.
  • PERLITE & VERMICULITE - Extremely slow breakdown near zero. Commonly used in commercial potting and bedding mix formulations with coir or peat. These are used to  improve aeration of the soil, promote consistent release of added fertilizer and improve moisture retention. 

STEP 5: Add minerals & silica for nutrition and cell structure. Follow our recipe, product packaging or internet to determine the amount to add. 
  • TEXAS GREEN SAND – slow-release trace minerals. Texas greensand (Glauconite) is an iron potassium, silicate that is green in color due to the minerals it contains. Greensand is a marine deposit that contains traces of many if not all of the elements which are in seawater. It has been used successfully for enriching soils for over 100 years. 
  • AZOMITE, EXCELERITE – Azomite is a natural volcanic mineral which is mined from the Utah desert and contains trace minerals. It has been reported to improve root systems, yields and general plant vigor in a variety of applications; from field crops and orchards to lawn and garden use. 
  • EPSOM SALT – Magnesium sulfate allows plants to take in these valuable nutrients including calcium, nitrogen and phosphorus. Ratio Ca 7-8 : Mg 1
  • SULFUR PELLETS – Sulfur, when converted by bacteria to sulfuric acid, lowers soil pH (acidifies), increasing plant-root access to many nutrients. Sulfur plays a critical role in the formation of plant tissue proteins and vitamin formation and is essential to the flavor of onions, garlic and other alums. For most garden annuals, vegetables and perennials, your goal is to create neutral-to-slightly-acid soil, with a pH of 6.5 to 7.0 . 

STEP 6: Mix enriched pile of amendments until all components are uniformly distributed. 

STEP 7: Combine old soil with enriched amendment pile. As you return your refreshed bedding mix to your box or containers, moisten each layer as you go so that your final result is moist enough to form a loose but distinct clump when squeezed in your hand.
 
STEP 8: Add cardboard on bottom of the bed or on top of left-over soil. This prevents weeds and adds more worm food. 

STEP 9: Add leaves or other brown and green debris (carbon) and coffee (attracts worms) on top of cardboard. Water this layer.

STEP 10: Fill bed with half of the renewed bedding mix, followed by a watering, and then fill with remainder with another watering.

STEP 11: Top mulch the bed with any of the following types of mulch to help retain moisture. Some of these will continue to add nutrients to the soil:
  • ALFALFA HAY - High in nitrogen and long lasting.
  • LEAVES -  Collect them in the fall and the more decomposed or “moldy” the better for your garden. 
  • WHEAT STRAW - Make sure not to use hay because it contains seeds.
  • PINE NEEDLES -  Helps create a more acidic soil.
  • HARDWOOD MULCH - Avoid cedar mulch. The oils from the cedar are antimicrobial / antifungal which you don’t want to disrupt in the soil
  • WOOD CHIPS - Do not mix into the soil because the decomposition process requires nutrients and will steal them from your plants.

MORE ORGANIC AMENDMENTS 
SEAWEED OR KELP MEAL
– Seaweed or Kelp Meal adds potassium (K), trace minerals, salts, alkalinizing the soil. It's an excellent bioactivator, waking the microbes in the soil to help break down organic matter.
SEAWEED SPRAY (alkalinizing) Alternatively, mix in a few handfuls of dried kelp meal.  Supposedly helps with heat tolerance but cannot find a reference for that yet. NOTE:  Excessive potassium or potash will decrease the soil's acidity so use it in a balanced way.)
FISH EMULSION  –  A fast-acting, organic liquid fertilizer made from the byproducts of the fishing industry. It is rich in nitrogen, phosphorus and potassium, plus trace elements such as calcium, magnesium, sulfur, chlorine, and sodium.
SHRIMP MEAL –  nitrogen, phosphorus, calcium, and chitin
CRAB MEAL, OYSTER OR LOBSTER  – nitrogen, phosphorus, calcium, and chitin
BONE MEAL – phosphorus “roots and fruits”
BLOOD MEAL – nitrogen “greening the giant”
ORGANIC N-P-K SLOW-RELEASE GRANULES  –  Down to Earth or Jobe’s 
WORMS
WORM CASTINGS
INSECT FRASS  –  Mealworm castings, cricket frass, is simply the feces of the insect. 
ROCK DUST (and/or regular sand) – very slow-release minerals and SOME water retention. (Less sophisticated than Azomite, Excelerite or Green Sand)
LIME - Generally not needed in central Texas because it is too alkalinizing

AMENDMENTS THAT CAN BE CONFUSING
Biochar (alkalinizing) “potash”–  If you're adding potassium to decrease the soil's acidity, use 1 to 2 pounds of hardwood ash per 100 square feet of soil. Other ways to add potassium are: add cut up banana peels and bury them 1 to 2 inches down in the soil or mix in a few handfuls of dried kelp meal or spray the soil with a liquid seaweed spray.

Coffee grounds – Brewed grounds are pH neutral but they do consume nitrogen as they decompose and compete with growing crops…but worms are mad for them. Some gardeners drop into vertical “wells” so worms can visit without significant contact with growing plant roots. ONLY UNBREWED COFFEE GROUNDS ARE ACIDIC.

More Epsom Salt for tomatoes, peppers or calcium loving plants at the time of transplant and for maintenance

Food Grade Diatomaceous Earth (FG-DE) is derived from fossilized remains of algae-like, single-cell plants called diatoms. Diatoms are some of the oldest plants in the world. They date back millions of years. These plants left behind chalky deposits called diatomite which is ground into a powder and purified for the consumer market. Chemically speaking, diatomaceous earth is 84% silica, and contains some 20 trace minerals, including small percentages of magnesium, sodium, iron and a good dose of calcium in the right ratio with magnesium for good utilization in building structures such as cell walls for healthy leaves and stems. In humans and animals, silica is essential for the building of healthy bones and teeth, skin, hair, and nails.

FG-DE is often used in the garden as a natural pest control substance. However, it can harm bees, other pollinators and ladybugs so use proper precautions as needed to reduce the chances of harm such as only using when needed for a specific pest, not over applying and avoiding use on vegetables and pollinator plants that are flowering.

Many studies have also been conducted to analyze the effect that FG-DE has as a soil amendment. These studies have shown promising results, suggesting that diatomaceous earth may significantly enhance nutrient retention and moisture retention in soil. https://www.absorbentproductsltd.com/food-grade-diatomaceous-earth-as-a-soil-amendment/ 
So far the conclusion is that diatomaceous earth doesn’t harm most beneficial microorganisms in the soil. Worms, for example, are not affected by the microscopic edges in diatomaceous earth particles.

Teaching Garden Update: Winter Cover Crops Chopped, Summer Cover Crops Seeded In

4/17/2021

Comments

 
​This past Saturday we said goodbye to our winter cover crop. It was beautiful to see the blooms of the hairy vetch and peas attract beneficial insects like ladybugs and then the mustards and radishes trapped pests like aphids and provided food for the ladybugs as they mated. 

We planted the cover crop mix of winter rye, peas, mustards and daikon radishes in a compacted and depleted area that was once a path. 
​

Before everything went fully to seed, we cut the stems at the base and then, trench composted the "green manure."  Never, uproot any of you crops because you don't want to upset the soil ecosystem or pull up the organic matter and nitrogen nodules that are in the roots of the plants. 

To keep the soil protected as the weather warms, we planted a summer cover crop blend of buckwheat, sorghum and millet. See our previous post to get cover crop ideas for your garden.

To learn about the benefits of cover crops, watch this episode from he fall video series.

Teaching Garden Update from Zilker Botanical Garden

4/14/2021

Comments

 
We transplated glass gem corn and tatume squash in our milpa mounds (also known as Three Sisters) this past Saturday. In a few weeks we will plant an heirloom variety of purple pole beans. The pole beans will climb the corn and help support it. The squash will start to vine out and protect the soil as the heat increases. Around the perimeter we planted Oaxaca Red Epazote (thanks for the donation thanks Danielle), Habanero Lemon peppers (thanks Sunshine Community Gardens ), Hopi Black Dye Sunflowers and Mexican Marigolds.

We will water weekly with fish emulsion fertilizer to encourage green growth. It is rich in nitrogen, phosphorus and potassium, plus trace elements such as calcium, magnesium, sulfur, chlorine, and sodium.

As things warm up, we will use seaweed kelp to help de-stress. Liquid kelp fertilizer appears to be a miracle product when used on almost any plant:
🌊 Many fruits become sweeter
🦞 Veggies are less prone to softening and often grow larger
🐙 Increases flower production on flowering plants
🐠 Increases overall plant resilience to disease
🦑 Cut flowers stay fresh longer
🐚 Encourages root growth, both in rate and root massma
🍤Fruits and vegetables survive longer post-harvest if treated with seaweed fertilizer pre-harvest

This garden is inspired by our special guest from March, Sam
Dixza Rugs & Organic Farm and the cloud people from central valley in Oaxaca, Mexico. The native people have been using this crop-growing system used throughout Mesoamerica for 10,000 years. If you missed Sam's talk last month, you can watch it here.

Seed In or Transplant Leafy Greens, Cereals, and Herbs
​We just passed the New Moon phase and are now approaching the First Quarter and are in Waxing Crescent. It’s a good time to plant leafy greens, cereal grains, and herbs that do well in heat. During the waxing of the moon (the period extending from the day the moon is new to the day it reaches its fullest point), the moon pulls moisture upwards. Seeds do well during this time because moisture is available at the surface of the soil. It’s always best to try to transplant and seed-in with the coming rains. Keep dancing for the rain that is in the forecast. As things cool back down this week, it will be a great time to plant these warm season greens, cereal grains, and herbs.

Seed-in or Transplant Warm Season Greens
  • Amaranth
  • Chard
  • Collards
  • Endive (Radicchio)
  • Egyptian Spinach (Molokhia)
  • Lamb’s Quarter 
  • Longevity Spinach
  • Malabar Spinach
  • Mustards
Texas A&M Agrilife Extension Leafy Greens Growing Guide.

Seed in Cereal Grains & Cover Crops
For the health of your soil, moisture retention, and to prevent weeds, keep your soil covered at all times with cover crops, compost and mulch. Bare soil invites weeds. Consider planting summer cover crops, such as buckwheat or black-eyed peas, or flax. Add compost, then mulch, to other bare soil areas. An inch or two of compost, and then two or three inches of mulch. 
  • Buckwheat
  • Flax Seed
  • Pigeon Peas (We found Northern Adapted Pigeon Peas this year. Thanks Rooted in Melanin for the tip.)
  • Sorghum
  • Southern Peas/Black Eyed Peas​
Transplant or Seed-in Herbs
A lot of herbs were damaged in the snow storm. If yours are not showing signs of life, here are some warm season herbs that can be transplanted.
  • Basil
  • Bay Laurel
  • Borage
  • Catnip
  • Comfrey
  • Fennel
  • Feverfew
  • Horseradish
  • Lemongrass
  • Lemon Balm
  • Lemon Verbena
  • Marigold
  • Oregano
  • Peppermint
  • Rosemary
  • Shiso
