Propagation
Stratify seeds for 2 to 3 months during winter in peat at a temperature of 1.1º to 5º C. (34º to 41º F). Sow seeds in pots then place them in a cold frame to germinate. Seedlings should be grown on in individual pots are at least one year with winter protection.

Note:
Care should be taken when selecting a sight as the tree has vigorous roots that can lift concrete and block drains.
