Mushrooms are an uncommon but very worthwhile crop to grow in your garden. Some mushrooms cannot be cultivated and can only be found in the wild, but plenty of varieties are easy to grow and a great addition to your yearly produce haul. Growing wine cap mushrooms is very easy and rewarding, as long as you provide them with the right conditions. Keep reading to learn more about how to grow wine cap mushrooms and wine cap mushroom cultivation.

How to Grow Wine Cap Mushrooms

Wine cap mushroom cultivation works best if you buy a kit of material that’s been inoculated with mushroom spores. Start in the spring to ensure a harvest sometime during the growing season.

Wine cap mushrooms (Stropharia rugosoannulata) grow best outdoors in a sunny location. To create a raised mushroom bed, lay out a border at least 10 inches high made of cinder blocks, brick or wood. You want about 3 square feet per pound of inoculated material.

Fill the space inside with 6 to 8 inches of a mix of half compost and half fresh wood chips. Spread your spore inoculate over the area and cover it up with 2 inches of compost. Water it thoroughly, and continue to keep the area moist.

Caring for Wine Caps

After a few weeks, a white layer of fungus should appear on top of the compost. This is called mycelium, and it’s the basis for your mushrooms. Eventually, mushroom stalks should appear and open up their caps. Harvest them when they’re young, and be ABSOLUTELY SURE you can identify them as wine cap mushrooms before eating them.

It’s possible for the spores of other mushrooms to take hold in your mushroom bed, and many wild mushrooms are poisonous. Consult a mushroom guide and always make a 100% positive identification before eating any mushroom.

If you let some of your mushrooms keep growing, they’ll deposit their spores in your garden, and you’ll be finding mushrooms in all kinds of places next year. It’s up to you whether or not you want this. At the end of the summer, cover your mushroom bed with 2-4 inches of fresh wood chips – the mushrooms should return in the spring.
