The seed is sown at approximately 150 seeds per metre and covered to a depth two to three times the diameter of the seed with fine sand or soil. After sowing, shading is required and the seedbed should be kept moist until germination occurs. Seedlings are usually left in the seedbed for two years before being transplanted to a larger area. Deciduous seed can be sown in rows or broadcast. Seeds are generally sown at a rate of 90 seeds per metre and to a depth approximately three times the seed diameter.
Irrigation stimulates germination and hastens growth.
The seedlings usually reach sufficient size for planting in a permanent location in two years. The preceding provides a brief introduction to growing trees and shrubs from seeds.
