|Pruning||Judicious pruning should be done during the dry season. Start pruning when the plants is 1.5 m tall. Then cut surfaces should be applied with copper fungicides. Decapitate the apical shoot to a height of 1 m to induce formation of secondary stems and bend the stems outward to promote good branching.|
|Fertilization||Organic fertilizer is recommended at the rate of 40 kg/tree/year applied once at the onset of the rainy season. Complete fertilizer (15-15-15) is applied twice a year at the beginning and at the end of the rainy season. The fertilizer is divided into four split application and broadcast around the plants every three months. Inorganic fertilizer is supplemented with organic fertilizer like decayed chicken dung at the rate of 5-10 kg/year split into two application. Fertilize with an application of a granular 6-6-6 fertilizer every four months to promote healthy foliage and fruit development.|
|Propagation||By air-layers, cuttings, or by graft. Seeds must be planted immediately yet a grown tree can take in excess of 15 years to bear fruit. 4-5" cuttings can be taken during active growth, and rooted in near 100% humidity with fair success, however air-layered and cutting grown trees tend to have weak root systems.|
|The fruit contains riboflavin and thiamine, vitamin B-2 and B-1 respectively. Riboflavin supports body growth and red blood cell production. Additionally, riboflavin helps your body to release energy from carbohydrates. Your body uses thiamine to break down sugars.
