Woody plant seeds can have different dormancy requirements. Identify the species before choosing soaking, chilling or another pre-sowing treatment.
Woody seeds have different dormancy requirements
A tree or shrub seed may need a particular seasonal sequence before it germinates. Identify the species and check propagation guidance before choosing a treatment. A general list of soaking methods is not a substitute for that information.
Record the source and treatment
Keep the collection or supplier name, sowing date and any treatment record with the container. That makes it possible to assess a batch later without guessing how it was handled. Separate differently named plants into labeled containers.
Give germination time
A slow result does not mean every seed needs more heat or water. Check species-specific expectations and inspect the growing medium for suitable moisture. Avoid repeatedly digging up seeds that may still be completing their dormancy cycle.
