How to Successfully Cultivate Mushrooms on Straw Bales

Cultivating on straw bales requires minimal effort. However, only certain types of mushrooms can be grown on straw. The best results are achieved with different types of oyster mushrooms (winter and summer oyster mushrooms, pink and golden oyster mushrooms) as well as wine cap mushrooms (Stropharia). Herb mushrooms can also be cultivated this way, but they tend to grow less reliably. The straw bale should ideally be placed in a moist, shady part of your garden.

Materials & Equipment:

• Straw bale
• Mushroom spawn: Grain spawn or sawdust spawn

Steps:

1. The straw bale is soaked in water for a day or thoroughly watered with a garden hose for several minutes. Depending on the density of the bale, a shorter or longer time may be required.
2. The spawn is then introduced into the straw bale. This can be done by making holes with a metal rod and inserting the mushroom spawn. Sawdust spawn can also be sprinkled over the straw bale. However, grain spawn might be picked up by birds if scattered.
3. After adding the spawn, the straw bale is watered again thoroughly.
4. After 3 to 6 months, the straw bale will be fully colonised by the mushroom mycelium, and the mushrooms will begin to fruit. Since mushrooms are also highly sought after by snails, it is advisable to take protective measures against snails around the straw bale. Depending on the size and location of the straw bale, mushrooms can be harvested periodically over the next months or even years.
