When should I plant my Plant and Grow block?

Different mushrooms fruit within different temperature ranges. That fruiting range is your starting point for “when,” because it tells you in which part of the season the mushroom naturally wants to perform. The three groups are cold, moderate, and warm fruiting species:

Cold fruiting species (about 40 to 65 F)

Cold group examples: Snow Oyster, Black King, Nameko, Chestnut, Blewit, Hen of the Woods, Enoki.

Moderate fruiting species (about 55 to 75 F)

Moderate group examples: Shiitake, Blue Oyster, Reishi (both varieties), Pioppino, Italian Oyster, Wine Cap, Chicken of the Woods.

Warm fruiting species (about 65 to 90 F)

Warm group examples: Pink Oyster, Almond Agaricus.

Critical timing note: Almond Agaricus should not be planted until all danger of frost has passed. These species may not survive harsh winters.
