Quick Answer
Evaluate log quality before inoculation by checking moisture levels (40-60%), bark integrity, and signs of pests or diseases, and by cutting the log into sections with a saw to assess the sapwood and heartwood.
Assessing Log Moisture
When evaluating log quality, it is essential to check the moisture levels. You want the log to be moist but not waterlogged. Aim for a moisture level between 40-60%, as this will allow for optimal mycelium growth. If the log is too dry, the mycelium may not grow, while a log that is too wet is more susceptible to mold and rot.
Inspecting Log Bark and Interior
Next, inspect the bark and interior of the log for any signs of pests or diseases. Check for cracks, crevices, or soft spots that can harbor insects or fungi. When cutting the log into sections, use a saw to assess the sapwood and heartwood. Sapwood is the lighter-colored, outer layer of the log, while heartwood is the darker, inner layer. You want to avoid logs with signs of decay or rot in the heartwood, as this can be difficult to treat and may affect mycelium growth.
Cutting and Sectioning Logs
To evaluate log quality, cut the log into sections of 1-2 inches (2.5-5 cm) in diameter and 6-8 inches (15-20 cm) in length. This will allow you to assess the sapwood and heartwood without compromising the entire log. As you cut the log, inspect the interior for any signs of decay or rot. Check for the presence of insects, such as beetles or ants, and any fungal growth. If you find any issues, it’s best to discard the log and select a new one.
