Choose Your Spawn

We offer:

• Fresh made to order sawdust spawn
• Plug spawn for easy log inoculation

Both are produced from our working farm cultures.

Start With the Right Logs

Chestnut mushrooms prefer fresh hardwood.

• Cut healthy hardwood logs
• Let them rest about 2 weeks after cutting so natural antifungal compounds break down
• Avoid old or dried logs
• 4 to 6 inch diameter is the sweet spot

Older logs dry out quickly and native fungi move in fast. Fresh logs win.

Sawdust Spawn Method

You will need:

• An inoculation tool
• Wax to seal holes

Drill, fill, seal.

If you want a low tech method, you can:

• Make a chainsaw cut and pack it with spawn
• Use the totem method
• Or for small batches, place logs in a closed trash bag at room temperature for a couple months

The bag traps moisture and often replaces the need for waxing. Just do not forget to remove them.

⸻

Plug Spawn Method

Great for beginners.

• Use an 8.5mm or 5/16 inch drill bit
• Drill 1 inch deep holes (a stop collar helps)
• Hammer in plug spawn
• Seal with wax to prevent drying

You can also use the trash bag method during early colonization to hold moisture and speed growth.

⸻

The Waiting Period

Chestnut mushrooms take patience.

Logs typically need 6 months to a year to fully colonize in a shady, moist location.

They are alive and vulnerable during this time. If you experience drought conditions, water them like you would a plant.

When you start seeing mushrooms naturally forming on the inoculated set, that is your signal the log is fully colonized and mature.

⸻

Fruiting

Chestnuts fruit in warm conditions.

When nighttime temperatures stay above about 60°F, you can:

• Soak logs fully submerged for 24 hours
• Expect harvest about a week later

Or let nature handle it during extended warm rain events.

⸻

Long Term Production

Logs can produce for 3 to 6 years or longer.

A rough rule:

About 1 inch of log diameter equals roughly 1 year of production.

Thicker logs last longer but colonize slower.

In our experience, 4 to 6 inches is the sweet spot.
