Oyster Cultivation Update

Checked on the oysters growing on cornstalks, and was excited to see mushrooms forming.

There is a couple of clumps forming and the mycelium has spread throughout. The mass may grow pretty fast now that that the fruiting has started! The timing might workout pretty well since the temperatures are almost stable enough to set the tub outside.

It is good to see this working because I didn’t have to put much work into it.There is not much much money invested either. The cornstalks were just broken up enough to fit in the tub and soaked in water. Since it is very low tech and low cost it has real possibilities for farmers, both those farming for a hopeful profit and those farming to provide food to  survive.

The cornstalks could have been bagged up and sent to the landfill, and instead will be turned into food. I will keep you updated on this project.

Mushroom Growing Kits

Mushroom kits are a great way to get started growing mushrooms.

Mushroom growing kits can be purchased online. They come in quite a variety of mushrooms. They produce fairly well and don’t take up much space. The different types usually involve sawdust and grain of some sort. The bag is complete with the growing substrate and spawn. The only thing left to do is to water them and put them in the right place to incubate. The directions vary but are usually detailed and clear.

Shiitakes take from 2 to 4 weeks to start flushing, and might flush for up to 16 weeks after. They need a temperature between 50 and 80 degrees.The kits are similar to how production mushrooms are grown. Most of them are grown on blocks kind of  like the kits, for fast production.

Lions Mane

The selection has become incredible in the last few years.You can find just about anything from Lions mane to Reishi. These kits would be a good start for beginners, and when done flushing, can be put to use in a mulch pile or outdoor experiments.

Reishi

Mushroom growing kits can be found online at Garden City Fungi and Fungi Perfecti, links on the homepage. Some stores carry the kits so watch for them.

Shiitakes for Food and Medicine

Shiitakes are a great way to eat your medicine.

ShiitakeShiitake mushrooms have proven to be an all around healthy food. The medicinal properties are almost as good as the Reishi, which is tasty but difficult to eat in volume.Western society has finally realized what eastern society has known for centuries. Mushrooms are good for you and have incredible healing properties for our ailing society.

Shiitake

It only stands to reason that you would want the shiitake to be organic. There is only a few places in the country to purchase them. Garden City Fungi, outside of Missoula, grows and sells organic mushrooms. The owners are serious about organics and I trust them for a safe local product. Stamets, of Fungi Perfecti,  is a champion of the organic mushroom movement, and I trust them for mailorder.

Lincs to both websites are on the Home Page. They are both certified organic. Support responsible growers and get to know your farmers.

Organic Mushroom Cultivation

Organic Mushroom Cultivation is critical for health and safety.

Most mushrooms concentrate, whether it is nutrients, minerals or toxins. They will grow on varied substrates so it becomes very important how and where your mushrooms grow. When using them for food it is important, but when using them for medicine, it seems crazy to put poison in your body when trying to heal! Organic is a good start, but it can be cheated, and I like to know exactly what my mushrooms have been exposed to.

Growing on trees and stumps seems organic and in most cases can be called organic, but it is necessary to know where these trees grow. Trees growing by busy roadways absorb toxins from exhaust as well as tires and brakes. Mushrooms then concentrate these toxins, and release them to the consumer. Substrates whether from farms or forest need to be scrutinized for contaminates.

Organic is a buzz word right now and I am glad people have been awaken to this worthy cause. Large agriculture and big business is in it for the money. They will grow on whatever is economically feasible, within our weak, and vague organic rules, to turn a buck. This should not be confused with what you or I consider to be organic, and safe.

The only safe way to know what you are eating, is to grow or pick it yourself. The only other way is to know your farmer, support them, and pay them well!

Article on Shiitake Cultivation

From an article at Chelsea Green; http://www.chelseagreen.com

The following is an excerpt from Fresh Food from Small Spaces:The Square-Inch Gardener’s Guide to Year-Round Growing, Fermenting, and Sprouting by R. J. Ruppenthal. It has been adapted for the web. Preview the book here.

Some of the most expensive and delicious gourmet mushrooms on the market are shiitakes, which also are credited in Asia with healthful properties such as lowering cholesterol and improving immunity to cancer. They are simple to grow in logs and take about 6 to 18 months to emerge. They can fruit in a wide range of temperatures, from just above freezing to nearly 90 degrees F. To grow shiitake mushrooms on logs, the process is as follows. You will need some hardwood logs (such as oak or beech) about 4 to 6 inches in diameter, a strong drill, shiitake spawn (preferably a strain that is suitable for your growing area; check with the supplier for more info), a hammer, and some hot wax (such as cheese wax or candle wax) that can be melted to seal in the spawn.

  1. Obtain hardwood logs. Logs that were cut recently are best, but let fresh wood sit at least six weeks before using. Leave the bark on if possible.
  2. Drill rings of holes in the log 1 inch deep. Space the holes about 6 inches apart and space the rings about 1½ to 2 inches apart. If possible, alternate the holes in equal spaces and with a zigzag pattern.
  3. Into these holes, insert the shiitake spawn. You can order this from suppliers in three forms: inoculated wooden
  4. dowels, loose sawdust, or pressurized sawdust pellets. If you get them in dowel form, pound these into the drilled holes with a hammer. Otherwise, insert the sawdust spawn into the holes.
  5. Most people like to seal in the spawn with hot wax, which provides a sterilized outer edge and prevents insects or animals from interfering during the incubation period.
  6. The mycelium typically will take 6 to 18 months to grow out through the wood. During this time, you can store the logs in a plastic bag in the garage or on the ground outside, covered loosely with a plastic tarp. Make sure to punch a few holes in any plastic covering you use to allow for adequate airflow.
  7. Keep the log moist by watering when necessary with nonchlorinated water. Under ideal conditions, the plastic will help maintain humidity, but during dry spells, you should water gently as often as twice per week. Other types of log-raised mushrooms need direct contact with soil (via a partially buried log), but shiitakes do not.
  8. The shiitakes will continue to bloom regularly for 4 to 5 years from the same logs. They will appear on their own schedule, but always remember to keep the logs a little moist. One secret to triggering a bloom (after the first bloom cycle) is to soak the log in ice water every two months or so. Mushrooms will appear within a week or so following the ice water treatment. You may want to alternate which log you soak so that they do not all bloom at once.

I believe anyone can be successful with mushroom cultivating at a basic level, but if you want to grow specialty varieties or turn this into a commercial pursuit, then you have a lot more to learn. Like any complex undertaking, you will need to research it well, read some books, network with a local group of mushroom enthusiasts, and learn through your own experimentation.
