Tools Used

• Companion Planting Spacing
  Primary

  Calculate spawn plug spacing in diamond pattern around log circumference.

• Seed-to-Harvest Timer
  Primary

  Track colonization timeline from inoculation to first fruiting.

• Mulch Depth Coverage
  Supporting

  Calculate mulch coverage around log stack for moisture retention.

• Hydroponic Yield Estimator
  Reference

  Estimate shiitake yield per log per season after colonization.

Reference Materials

• Fresh Logs Only

  Logs cut more than a month ago may harbor wild fungi that outcompete shiitake spawn.

• Wax Every Hole

  Unsealed drill holes invite Trichoderma — wax every plug immediately after insertion.

• Free Wood Source

  Contact arborists or utility companies for fresh hardwood logs — often free after tree removal.
