The following is based on studies conducted in Nicaragua:
With Irrigation and Fertilization
A spacing of 10 X 10 centimeters (4" X 4") has been recommended when growing Moringa intensively as a crop. Moringa green tops can be harvested every 35 days. Dividing the field into 35 parts, and planting one part a day for 35 consecutive days, would allow daily harvesting on a 35 day cycle.
The Moringa tree grows mainly in semi-arid tropical and sub-tropical areas. It grows best between 25 and 35 C (77 to 95 F), but will tolerate 48 C (118 F) in the shade and can survive a light frost. Altitudes below 600 m (1,970') are optimal, but it has been known to grow at altitudes as high as 1200 m (3940') in the tropics.
