Please let me know what the deficiency might be. My drumstick tree is not fruiting despite profuse flowering.
Tree Not Fruiting Despite Profuse Flowering
Certified GKH Gardening Expert
If your drumstick tree (Moringa) is less than 2 to 4 years old, it may be too young to produce fruit. It should produce fruit in the next few years. Also, if you harvest leaves from the tree, it may not have enough energy to produce fruit.
Another possibility is that it needs potassium. Adding a potassium-containing fertilizer might help.
