Ever wonder how to grow Oak trees from acorns? It’s easy! Late Fall is the perfect time of year to collect acorns to start growing new Oak trees over the Winter. Late dropping acorns (October and November) are typically healthiest. A healthy acorn specimen suitable for growing an Oak tree is one that is plump with a cap that is loose and/or easily removed. A naturally split or cracked acorn is fine, but do not collect damaged or crushed acorns.
How To Grow Oak Trees From Acorns:
- After inspecting the collected acorns, place them in a mixture of 1/2 peat and 1/2 loose barley in a clear zip-lock plastic food storage bag. Do not crowd the acorns. They should be loose in the mixture and the bag should not be more than half-full.
- Seal the bag and store it in the refrigerator throughout the Winter. Periodically check the moisture level -it should be damp, but not wet. At some point during the winter, the acorns should split open and white sprouts should begin to appear and grow.
When To Plant Acorns:
- In early Spring (late March to early April), fill individual plant pots with clean potting soil. Place the sprouted acorns horizontally in the soil about 1 1/2 inches deep and water. Place the pots in a south-facing window or under an artificial light source and keep the soil moist.
- During the next few weeks, the acorns will sprout into a sapling, with a few tiny, yet visible Oak leaves. As the trees grow, transplant them into larger containers. Do not allow the trees to become root bound, or dried out.
- You may keep your trees in plant pots indefinitely, or until they have reached a desired size to plant outside. Before planting them in the ground, introduce the trees slowly to the outdoors by placing them in cooler areas such as on a porch, or in a shed or garage for a few days at a time. Transplant them outside in the early Fall before danger of frost.
