Saving seeds from last year’s crop

Seeds are pretty inexpensive, and you can find just about any variety of anything in the world online. But this year we selected seeds from some of our best organic plants that were left in the garden to fully mature and produce seeds well into Autumn.

I take small brown paper bags, place the seeds in them, label them with the variety and date and allow them to fully dry for a couple weeks. Since warm temps and humidity can ruin your seeds, place them in small airtight jars and then store in a cool place like your fridge.

Fermenting Seed: This year I went a step further with my tomato seeds by fermenting them. This removes the seed’s gel which contains a germination inhibitor and other potential disease. The entire process take about 5 days, but the steps are pretty easy.

 

Take a 1/4 to 1/2 cup of filtered water and place the freshly harvested tomato seeds in the water and sit in a cupboard for 3-5 days. Over time, the seeds will float and then sink. A film or mold will develop over the top and the water will become a little cloudy. It will also smell really bad. This is normal.

Close to the 5th day, or when all the seeds have sunk to the bottom, carefully remove the top film and then add water. What you are wanting to do is stir up the pulp and other sediment to slowly pour off until you can put the seeds in a sieve and rinse. Set them aside on a paper plate (seeds will stick to napkins) to dry. You should have fuzzy seeds ready to plant next year!

Searching for wild ‘Hen of the Woods’ mushrooms in Tennessee

As you enjoy the beautiful colors of Fall this year you may notice several varieties of wild mushrooms growing at the base of some large hardwood trees in Tennessee. One mushroom in particular we need your help finding is called “Hen of the Woods,” or Maitake (Grifola Frondosa).

If you find one of these beautiful native mushrooms, and you live within about 75-100 miles of our organic farm in Woodbury, TN, we’d love to come visit and take tissue samples to replicate in our farm’s mushroom lab.

What to look for: The huge 9 lbs. Maitake pictured here was found on our property October 22, 2012 at the base of a large oak tree. You can find them either at the base of oaks and other hardwoods or running along large surface roots fanning out from the tree. They usually return year after year (learn more).

What we’ll do: we will bring a small lab kit to sample the tissue, replicate the mycelium in a petri dish and then spawn the culture samples into various growth mediums including sawdust and pegs for logs. If you find one, call us at 615-469-7778. We will only positively identify this variety of mushroom in person, but close-up photos emailed to us can help us decide whether to make the trip.

If you are interested in growing your own Shiitake or Maitake mushrooms on logs at home, send us a short message to receive future notifications on scheduled workshops or availability of spawn pegs and inoculated logs from Half Hill Farm.

Read more: Paul Stammets has a nice article that includes excellent research on Maitake mushrooms and its medicinal value, in particular for Type 2 Diabetes. Below is the nutritional value of Maitake mushrooms excerpted from the article.

  • 377 calories per 100 grams dry weight
  • 25 percent protein
  • 3-4 percent fats (1 percent polyunsaturated fat; 2 percent total unsaturated fat; 0.3 percent saturated fat)
  • ≈60 percent carbohydrates (41 percent are complex carbohydrates)
  • ≈28 percent fiber
  • 0 percent cholesterol
  • B vitamins (mg/100 g): niacin (64.8); riboflavin (2.6 mg); and pantheonic acid (4.4 mg)
  • High concentration of potassium: 2,300 mg/100 g (or 2.3 percent of dry mass!)

Organic mushroom production begins at Half Hill Farm

Today is the first day of Fall and the official start of our organic Shiitake and Maitake mushroom production at Half Hill Farm!

This Summer we began working with a couple of local mills to source high quality organic wheat bran and hardwood sawdust for our indoor mushroom grow operation. Maitake jars (Hen of the Woods) and Shiitake blocks start in the Shroomery this weekend. Yesterday, we inoculated about 60 white oak logs we got when Mr. Logan had to take an old tree down after a bad storm.

Everything about growing mushrooms feels right. While producing a food with near magical health benefits, we are also sequestering larger volumes of carbon from felled trees into our soil through compost creating a multi-threaded sustainable loop that increases the health of our soil, our food and ultimately our planet.

Availability: It will take a few weeks before the first mushrooms appear, and you know we’ll post results along the way on Facebook like doting parents.

Our organic mushrooms will be available fresh by the pound to individuals or local restaurants or dry by the ounce online. Starting next year, we’ll host workshops and make fully inoculated logs, blocks and jars for folks wanting to grow their own mushrooms at home.

RECIPE: Garlic Scape Pesto

Around the end of May through mid June, some of our organic Western Rose garlic (and most any hard-neck garlic) send up flowering shoots called scapes. This usually means the bulbs are forming and that harvest is not too far behind.

We cut the scapes off to force the plant to send its energy to the bulb, remove the flowering top and use them much like chives in food. They have an amazing fresh flavor that isn’t as strong as garlic.

Here’s a very simple recipe for garlic scape pesto we enjoyed (pictured above). If local growers have them, they’ll be at your farmer’s market right now. We hope to have more next year.

1/2 cup garlic scapes
1/4 cup grated parmesan cheese
1/4 cup pine nuts
3/4 cup basil
1/2 tsp kosher salt
1 tsp fresh lemon juice
3 tbsp extra virgin olive oil

Toast pine nuts in a skillet. Blend toasted pine nuts with garlic scapes, cheese, basil, and lemon juice in a food processor adding olive oil until smooth. Salt to taste.

Using mycorrhizal fungi in organic farming

One of the most important organic cultural practices I use on the farm is inoculating crops with mycorrhizal fungi. The photo above shows an application on one of 100 organic hop rhizomes we just planted. The symbiotic relationship between this fungus and plant roots is essential for healthy soil and plants. It’s also the secret that all of the current world record pumpkin growers don’t want you to know.

There are a couple types of mycorrhizal fungi. Endomycorrhiza work with certain plants by attaching to the root intracellularly while ectomycorrhiza work extracelluarly. Here is a good resource to find out which mycorrhiza you need for various plants and trees.

How it works: The fungi is naturally occurring in healthy soil all over the world. The largest living organism on the planet is a 2,400 year old 2,200 acre mycelial mat discovered in August 2000 in Oregon’s Malheur National Forest. Mycorrhizae are the very life of our planet’s soil creating a network of microbial life that naturally mitigates disease, nutrition and water concerns in the cultivation of crops. Mycorrhizae reduce the use of tilling, irrigation and chemical inputs in aggriculture. It also helps sequester carbon and is a key environmental relationship in our survival on the planet. Many organic farmers who use mycorrhizal fungi never have to water their crops even during drought. You can see several of these side-by-side comparisons pictured here online that illustrate exactly why.

Conventional farming methods using chemical fertilizers, pesticides and tilling are slowly destroying this natural relationship in favor of predictable short-term outcomes from dependence on expensive inputs that often hide destructive and unsustainable results.

Perfect design: Mycorrhizae are basically a mushroom (mycelium) that feeds off the plant’s sugars through its root system. What the fungus does in return for plants is truely amazing: it takes nutrients and water from the soil and feeds the plant by becoming a huge network of extended roots. The fungi is also what breaks down rocks and minerals for plants. It also makes plants more drought resistant as their access to soil moisture is more than ten times that of non-inoculated plants. One application to roots during transplanting or seeding lasts the entire life of the plant, and the results are indisputable.

There is a lot of simple research showing plants do much better using mycorrhizae than using conventional fertilizers. Here is a 6th grader’s science fair project using Fungi Perfecti’s MycoGrow (what we use at Half hill Farm) to show you how simple this is to understand.

Certified organic hops taking root in Tennessee

Two things I’m very excited about arrived at the farm this week. First is the endomycorrhizal fungi I’ll tell you more about later. The second are the first of our Cascade and Centennial hop rhizomes! They’ll go in our freshly cut beds as soon as the weather permits.

Half Hill Farm is the only farm in Tennessee providing a local source of USDA certified organic hops (certifying April 2013). The Tennessee Department of Agriculture stopped keeping records of Tennessee’s hop production sometime before Prohibition when machine harvesting began concentrating the nation’s hop production in other states. The USDA could find no records of commercial production in Tennessee.

Half Hill Farm is proud to serve the needs of a growing craft beer culture in Tennessee that celebrates an American craft spirit of community, ingenuity, and sustainability. If you are a local craft brewer and want to visit our farm, get in touch, and grow with us!

First organic seed starts for Half Hill Farm

Vince got our very first organic seed starts going in the greenhouse this weekend as the last of the snow melted. This first batch is:

  • Organic tomatoes: Roma, Lemon Drop, Kellogg’s Breakfast, and Giant Beef Steak
  • Organic peppers: Jalapeno, Peperoncini, Orange Bell, California Bell, and Sweet Pickle Peppers

After finding the temporary greenhouse temperature dropping below freezing, we decided to use this germination pad. It will keep the soil between 70-80 F degrees. We ordered a much larger 2ft x 4 ft pad for more starts we’ll plant later this week as well as for re-potted plants.

The soil we’re using consists of an OMRI-listed peat, soil from our orchard field and garden compost. We’re also using Jiffy peat cups for transfers.
