As with rensonii, seed yields are limited in the first year, but increase with age and size of the trees. The nutritious pods attract insect attack. At maturity, the pods turn brown and split, discharging their seeds. It is important to harvest pods before the discharge of seeds. As with rensonii, pods should be harvested by hand-stripping cutting branches will decrease subsequent seed crops.
Branches are small, soft and damage easily.
During harvesting operations, care must be maintained to avoid damaging the plants. Flemingia can produce two seed crops per year. Harvested pods are sun dried for 2 days. Once dry, put pods in a sack and gently pound with a stick. This process will detach the seeds from the pods.
