Wood-chip garden beds

What it is

Wine caps grow in wood chips or straw¹. The Brooklyn Botanic Garden guide builds a bed in layers of one to two inches of chips, sprinkling grain spawn between them, to about six inches deep in total, in partial shade¹.

Cornell waters a chip bed at inoculation and once a week for a month, and notes that a shaded bed of chips four inches or deeper holds its moisture². A bed keeps producing for about three years if you add fresh chips on top each year¹.

A University of Missouri trial found that straw beds produced more wine caps than wood-chip beds in its first experiment³, so a mix is worth trying.

What it suits

Wine cap (Stropharia rugosoannulata), also called king stropharia²¹.

Species notes are on the species page; for the mushrooms themselves, see Ohio Gourmet Mushrooms.

Equipment

• Wine cap grain or sawdust spawn
• Fresh hardwood chips, and straw if you like
• A shady or partly shady spot
• A hose or watering can

Time to first harvest

About 2–6 months. The Brooklyn Botanic Garden expects mushrooms within two to six months¹. Missouri’s beds began fruiting 44 to 58 days after inoculation³. Cornell gives a wider incubation range of 2 to 12 months for wood chips².

Contamination and other risks

• The bed drying out in sun or wind².
• Slugs and wildlife, which favour wine cap fruit⁴.
• Other mushrooms appearing in the bed. This site does not give identification advice; only eat what you are certain you planted, and if in doubt, do not eat it.

Steps, in overview

1. Pick a spot. Partial shade, near a hose¹.
2. Layer. Spread 1–2 inches of chips, sprinkle spawn, repeat to about 6 inches¹.
3. Water. Soak it at the start and weekly for the first month².
4. Wait. Keep it damp but not soggy¹.
5. Harvest. Pick young, before spores drop; dark dust on the stem means they have¹.
6. Feed it. Add fresh chips each year¹.

Common mistakes

• A thin layer of chips in full sun².
• Letting mushrooms get old in the bed before picking¹.
• Planting after the first fall frost; the Brooklyn guide plants from the last spring frost to a few weeks before the first fall frost¹.
