Germination Information
Pre-treatment: Seeds are placed in cold moist stratification for 17 to 28 days or soaked in fresh water overnight, cleaned, and then placed in a plastic freezer bag with an equal amount of dry perlite. Keep in refrigerator at 15C for 1 month.
Establishment: Seeds are collected between September 1st and December 15th. Mature acorns are brown. Collect when the base of the acorn turns brown and is easily pulled from the cup. The protocols provide two different pre-treatment methods, one involving cold moist stratification and the other soaking in water and refrigeration.
