Your garden selection can become much richer with these 3 types of mushrooms which any “urban farmer” can grow even with limited space.
Yes, if you want to expand beyond the usual tomatoes and herbs, why not try growing mushrooms?
Gourmet mushrooms can be pricey and sometimes real hard to find at your local farmers’ market, so growing them yourself can be a great alternative to looking for them.
Mushroom cultivation needs the same basic supplies, no matter what type of mushroom you will be growing. The two main requirements are spawn and substrate.
Spawn: Spawn for mushrooms is similar to the seeds for vegetables: it carries the mushroom mycelium and “plants” it wherever you want it to grow. For beginner growers, the spawn is usually purchased from a reputable supplier, typically online or via catalog. (Some larger cities have mushroom-supply shops, as well.)
Substrate: The spawn is then planted in some sort of substrate, such as logs, straw or wood chips. The mycelium will take over and spread until it has enough momentum for the mushrooms to fruit. Mushrooms often fruit several times from the same substrate, but when the mushrooms have thoroughly broken down your growing medium, it makes a great supplement to your garden compost.
The next step: Choose your mushrooms
When choosing your mushroom, keep in mind the amount of space and shade you have where you live.
Here we suggest 3 nutritious and delicious mushrooms which any dedicated person can easily grow:
- Oyster mushrooms
Anybody experienced with mushrooms will tell you that oyster mushrooms are one of the simplest mushrooms to grow. Oyster mycelium is very vigorous and can quickly overtake a substrate. There are a variety of ways to grow oysters, but here is a quick and simple one for urban farmers.
This is how you do it:
- Visit your local coffee shop and get a bag of used coffee grounds. These always make a great medium for growing mushrooms because the heat of the coffee-making process essentially pasteurizes the grounds and kills off any other organisms that might compete with the mushroom mycelium. Mix the grounds with your oyster spawn in a bucket or storage tub (any size will do the job), and drill some air holes for better circulation. You can store the bucket in your apartment, wherever you have spare, dark space—a closet works great. It’s important to keep the coffee grounds moist by misting them with water occasionally.
- After about a month or so, you should be able to see the white mycelium that has overtaken the coffee grounds. Move the bucket to a spot where it will receive some sunlight, such as on your countertop or near a sunny window. Continue to mist the coffee grounds each day to ensure adequate moisture levels.
- In about a week, you should begin to see your oyster mushrooms fruiting. After the first harvesting, you can add some additional coffee grounds and hope for another harvest by repeating the process again.
- Shiitake mushrooms
Shiitake mushrooms have a rich, earthy flavor that is very different from a typical grocery store button mushroom. You can cultivate them in your backyard by inoculating small (about 4 to 8 inches in diameter), freshly-cut logs or branches.
Start them like this:
- The inoculating process requires drilling holes in the logs, filling them with spawn and sealing the holes with hot wax. The completed logs simply need a shady area to wait for the mycelium to take over. So, consider using a shade tree or space under a porch. The process takes around 6 months on average. If you don’t have a suitable shady spot in your nice urban yard, consider building a small awning for your mushrooms logs by using a tarp.
- After six or so months, you should be able to see mycelium in the form of white spots on the ends of the logs, which means the shiitakes are ready to fruit. You can wait for them to fruit naturally, or you can force them to fruit by soaking them in water for 24 hours. Shiitake logs will fruit several more times over the course of many years depending on the size of the log.
- Wine Cap (Stropharia) mushrooms
Again, if you don’t have enough room for a stand of shiitake logs in your city yard, consider growing wine cap stropharia, “garden giant”, burgundy mushroom or king stropharia (Japanese: saketsubatake). This delicious type of mushrooms can be planted right in your perennial garden beds or landscape areas.
Start them like this:
- In the spring, choose an area that is about 16 square feet, and cover it with fresh hardwood wood chips, mixing in your wine-cap spawn—a 5 pound bag of spawn is ideal for this size project. Soak the area through and through. By fall, your wine caps will have sprouted up right among your garden plants. The mycelium also helps keep the soil healthy for your plants, so wine caps are a win-win!
- Be sure to clearly identify your wine caps before eating them, as other mushrooms may sprout in your wood chips, as well. Check a mushroom identification guide or look online for more info.
Wine cap mushrooms are wine-colored (reddish-brown) when they are young, with dark gills and a fibrous stem (hence the name), and fade from tan to yellowish-brown as they mature.
How to harvest and store your “urban” mushrooms
It is recommended you harvest your mushrooms regularly in order to avoid damage from insects, and prevent them from drying out. Ideally, mushrooms should not be washed in water, but simply wiped clean with a paper towel.
Mushrooms are best when used fresh for cooking and make a great addition to a great variety of meals, including omelets and stir-fry dishes. You can also store them in the refrigerator to extend their shelf life for a couple of days.
If your harvest outpaces the demand for mushrooms in your kitchen, try drying the excess fungi in a food dehydrator or oven set to 150 degrees Fahrenheit for a couple of hours, turning them occasionally.
Dried mushrooms can be rehydrated later on for instant use in different stews and soups. I don’t know about you, but I simply cannot imagine a good home-made soup without a bunch of mushrooms in it.
To sum up, if you are ready to take your home gardening to the next level, this is the right thing to be done!
