It is important to practice thorough weed control until trees are well established. Once established, rensonii will dominate most weed vegetation. Seven months after establishment plants will produce seed, however quantity and quality of this first crop are low. Plants will be in full seed production by the second year. Seed yields will increase as the plants become larger.
Seed is mature when pods turn brown.
Green pods produce inferior seed. Harvest by hand stripping brown pods from branches. Use the least force necessary to remove mature pods. Green pods should remain on the branch to mature for subsequent harvest. Hand harvesting allows four seed crops per year.
