Getting the most from your Shiitake mushroom log

Shiitake mushroom logs in the woods at half Hill Farm

Last night looks like the last of forecasted freezing temperatures for early Spring here in Middle Tennessee. If you have one of our Shiitake mushroom logs marked SP15 (Spring 2015) or earlier, now is the time to prep your log for an early Spring flush.

Shocking logs: Get a five gallon bucket and fill it with rain water or water from a nearby creek and then soak your log for 24 hours. Place the log in a wooded area with roughly 80% shade. You can place it under a bush near your house’s North side if you do not have woods. If you have more than one log, use a larger tub like the one pictured above. The water should not be chlorinated tap water and should be very cold. This hard soak and cold temperature followed by the gradual warming of outdoor Spring temps will “shock” the mycelium into “pinning,” the beginning stages of mushrooms.

Pinning: Each pin that forms pushes through the bark as you see pictured above and will develop into the beginnings of a mushroom within 2-3 days followed by a rapidly growing mushroom over a five day period. Depending on the weather throughout Spring, you could experience 2-3 natural cycles of mushrooms with roughly two week resting periods between each flush.

Harvest: Once you start to see the mushrooms unfurl their outer edge (typically tucked under the mushroom cap), it is time to pick mushrooms. At this point, the mushroom is in the early phase of releasing its spore. Simply cut them off at the log, brush off any debris and either eat them fresh, store them in the fridge for up to two weeks, or dry them to use for months to come.

How to purchase: Each Shiitake mushroom log from Half Hill Farm produces up to 90% of the log’s dry weight in mushrooms over a 3-5 year period. You can purchase your own inoculated logs from 15 lbs. one foot logs up to 50+ lbs. four feet logs at our farm here in Woodbury, TN. Just give us a call and let us know you’re coming!

RECIPE: Shiitake mushroom soup

Once your Shiitake logs from Half Hill Farm start producing mushrooms, you can dry them, store some in the fridge for a couple weeks, or eat them! That’s exactly what we did using the following recipe and an unexpected January harvest.

There’s a lot you can do with your Shiitake mushrooms and a lot of good stuff it will do for you. One recent study, for example, shows medicinal compounds in Shiitake mushrooms can eradicate HPV, a virus that causes 99% of all cervical cancer, 95% of anal cancer, 60% of oropharyngeal cancer, 65% of vaginal cancer, 50% of vulvar cancer, and 35% of penile cancer. Here’s more research on this and other mushrooms we grow, and here’s our recipe for how to make some Pho-tastic Shiitake mushroom soup.

Shiitake Mushroom Soup

  • 2 cups chopped Shiitake mushrooms
  • cubed tofu
  • 4 cloves of garlic
  • 4 tbsps of fresh grated ginger
  • chives
  • cilantro
  • 4 cups chopped Napa cabbage
  • rice noodles (or rice & quinoa)
  • 8 cups of chicken or vegetable broth
  • soy sauce (or Bragg’s) & lemon to flavor

You can use either rice noodles or a little rice and quinoa. Either way, cook these first and set them aside. You won’t need much – about a total of half a cup if using rice/quinoa.

Put a little olive oil in the soup pot you plan to use and cook your cubed tofu. When complete, stir-fry the chopped garlic cloves and ginger with the cooked tofu. This takes a couple minutes. Now add the broth, mushrooms and either noodles or rice/quinoa. Let this simmer for 20 minutes and then add the Napa cabbage and let simmer for five more minutes before serving.

Place a little chopped cilantro and chives in a bowl and fill the bowl with soup. Add a generous squirt of soy sauce or Bragg’s and a squeeze of a couple lemon wedges and enjoy!

How to get more vitamin D from your Shiitake mushroom harvest

If you purchased a Shiitake mushroom log from Half Hill Farm that is tagged “F14,” now is the time to follow your soaking / shocking steps to get your first edible mushrooms within a week.

Once your Shiitake mushroom log starts producing mushrooms, there’s a simple technique that dramatically increases their vitamin D before you either eat them or dehydrate them for long term storage.

Mycologist Paul Stamets details this simple process and science here, but the basic steps are pretty simple:

  1. Remove stems and slice into roughly half inch slices.
  2. Spread slices evenly on drying racks (anything that allows air flow) in the sunshine with the gills facing up for 6 peak hours avoiding early morning dew and evening moisture.
  3. Bring the mushrooms indoors overnight to avoid humidity, then repeat 6 hours of sun exposure the next day to achieve 12 total peak hours of UV exposure.
  4. Finish completely drying your Shiitake mushrooms in a dehydrator, and store them in sealed jars. To enjoy anytime, simply soak them for an hour and follow most any recipe for fresh mushrooms.

According to Stamets, Shiitake mushrooms that are not exposed to sun may have less than 40 IU/100g of vitamin D. With the steps above, you can expect 46,000 IU/100g of vitamin D, D2, D3, and D4!

To achieve healthy serum levels of vitamin D exclusively from your dried Shiitake mushrooms, you will need to eat no more than 10 grams a day which is roughly equivalent to 100 grams of fresh Shiitake (3.6 ounces).

Purchase your own mushroom log: Our one foot Shiitake mushroom logs are available for scheduled pick up on our farm in Woodbury, TN. They are $22 and will produce 15-20 lbs. of mushrooms over a 3-5 year period. Here is how to get yours.

Make your own mushroom log: Schedule your own private 2-3 hour mushroom log workshop for groups of up to four people on our farm, take home the log you make, and start turning your own logs into a sustainable food source. Here’s how to schedule your workshop.

Grow your own mushrooms with our inoculated logs

What better way to celebrate the first full day of Spring than inoculating some locally harvested oak with medicinal and edible mushrooms! These one foot Red Reishi, Shiitake and Turkey Tail mushroom logs from Half Hill Farm are available for local pick up ($22) or ordering online if you live outside the area. We accept most major credit cards. Call 615-469-7778 for pick up.

Each log comes with instructions on how to care for your log to ensure it produces for many years to come. You can expect between 50% – 90% of the log’s weight in mushrooms over the years depending on the variety and proper care.

We also offer spawn pegs in 100 count units to inoculate your own logs. These are $12 per unit (100 will inoculate roughly three 4 feet logs) and are created from our cultivated spawn in the farm’s Shroomery lab. 500 or more are $10 per unit. These also come with basic instructions. Check out our other products for the more advanced mushroom grower.

Workshops: We do Spring and Fall workshops for small groups up to four people by appointment. You’ll learn all the basics in a quiet rural farm setting 12 miles East of Murfreesboro, TN and take home the log you inoculate.

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.
