Cultivation and Care

Propagation from Seed: Seed is best sown as soon as it is ripe in a cold frame. It is important to protect the seeds from mice or any seed-eating creatures. Seeds can be slow to germinate. One way to reduce the waiting time is to harvest seeds just before it is fully ripe, when the embryo has fully developed but before the seedcoat hardens and sow it immediately in a cold frame. If you are growing large quantities of plants, it is best to sow them directly outdoors in a seedbed until they are large enough to out-plant. If growing small quantities, pot the seedlings as soon as they are large enough to handle and grow them in individual pots for the first year. Plant them in the late spring into nursery beds or their final positions.

General Upkeep and Control

Trees should be bought and planted when they are no more than eight feet in height. The best time to plant is in the fall or spring. Ball and burlap trees should be planted in the early spring. Pruning should be done in the winter or very early spring. CRBE2"Seedlings develop taproot, thus should not be kept in seedbeds longer than one year. If transplanted in autumn, amend soil, fertilize, water thoroughly, mulch adequately and avoid winter salt spray. Pruning should be done in the winter or early spring in order to maintain a clear shoot leader on young trees and/or remove the weakest branches to allow more light to pass through. Suckers or stems arising from the roots should be removed when they become noticeable.
