Sow seed 1/8" deep, tamp the soil, keep moist, mulch the seed bed, remove mulch upon germination, cover seedbed with some shade.
It can also be sown in early spring, though it might not germinate until after the next winter. If there is sufficient seed, an outdoor sowing can be made in spring.
Pot-grown seedlings are best potted up into individual pots once they are large enough to handle - grow them on in a cold frame and plant them out in early summer of the following year. Trees transplant well when they are up to 80 cm tall, but they are best put in their final positions when they are about 30 - 45 cm or less tall, this is usually when they are about 5 - 8 years old.
Larger trees will check badly and hardly put on any growth for several years. This also badly affects root development and wind resistance. (info source: pfaf.org)
