Sprinkle the spores onto the compost and slightly compact them in by pressing firmly on the surface - I didn't say to squash them , I just said press firmly. Sprinkle some peat moss or more compost over the surface after you've laid your spores, about 1 1/2 inches will suffice.
Regardless of the season you should always keep the bed moist and well watered. Within a month your first mushrooms should be ready to harvest. Allow some mushrooms to stay in the bed , open their caps and spread more spores to ensure future harvests.
You'll find them popping up wherever conditions are conducive to their growth. When the initial bed is exhausted and has ceased to produce, add a 1 inch layer of fresh wood chips or shredded yard leaves, add some more spore and it will produce again.
Wine cap mushrooms are wine-colored when young, they turn a yellowish-brown when mature. They are best harvested before they turn colors.
