Oaks are most often propagated from seed. No pretreatment is necessary. Plant immediately – outdoors or in deep containers to accomodate long initial taproot. Many oaks require cold temperatures to initiate shoot
development. Protect outdoor beds with Seed Collection:
Best quality acorns are picked or shaken from the tree. Collect when color has changed to brown. Best if sown immediately as acorns lose viability quickly in storage. Short-term storage in moist, shaded saw dust or sand. Acorns to be sown immediately can be soaked in hot water for 15 min. to prevent weevil infestation. Seed Treatment:
Stored seed should be fumigated with methyl bromide. Commercially Avail:
