Hen of the Woods (Maitake)

Hen of the woods is mostly wild-foraged around mature oaks, although specialist prepared hardwood blocks can offer a home-growing route. Start with a labeled Grifola frondosa kit and follow its exact instructions: wood-based nutrition, humid air, fresh-air exchange, and a suitable temperature shift are more important than fertilizer.

Sun

Shade or indirect light; species-specific fruiting conditions

Water

Keep substrate moist, not waterlogged; provide humidity and fresh air

Substrate

Mostly wild-foraged wood-decay fungus at oak bases and occasionally other hardwoods; specialist cultivation uses prepared hardwood sawdust blocks.

First harvest

Supplier-dependent; no fixed date

Tips

• Choose a reputable Grifola frondosa kit rather than expecting purchased spores to establish near a tree.
• Keep the block humid but not saturated and provide the supplier’s prescribed ventilation.
• Do not fertilize blocks or inoculate healthy landscape trees, and discard contaminated kits.
• Harvest expanding clusters while fronds are tender, before margins toughen or discolor.
• Use labeled edible spawn or a food-grade kit; never eat mushrooms based on this app or where they happen to grow. Have wild specimens confirmed by a qualified local expert and cook thoroughly.

Start with labeled species-specific spawn or a specialist kit only when you can maintain the supplier’s required colonization and fruiting conditions.
