How to Propagate White Oak?
Acorn (Seed) Propagation
Plant acorns as soon as possible after collection since they lose viability quickly if allowed to dry out; protect young seedlings from rodents and deer.
- 1 Collect fresh, mature acorns in autumn as soon as they drop, discarding any with holes or that float in water.
- 2 Cold-stratify the acorns by storing them in slightly moist sand or peat in a refrigerator (around 1-4C) for 60-90 days.
- 3 In late fall or early spring, plant the stratified acorns about 2.5 cm deep in well-drained soil or deep nursery pots.
- 4 Keep the soil consistently moist but not waterlogged until germination occurs, which can take several weeks.
- 5 Transplant seedlings to their permanent location once they have a sturdy taproot, ideally while still young, since white oak resents transplanting.
