Troubleshooting
Khirni problems — and how to fix them
Khirni (Manilkara hexandra) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Very slow growth and long juvenile phase
Trees grown from seed take 7+ years to produce economic fruit yields. This is expected — not a sign of poor health. Grafting onto vigorous seedling rootstocks can reduce the juvenile period somewhat.
Scale insects and mealybugs
Common sap-sucking pests in tropical conditions. Monitor stem axils and leaf undersides; treat with neem oil or horticultural oil at the first sign of infestation. Heavy infestations weaken flowering and fruiting.
Fruit-piercing moths
Nocturnal fruit-piercing moths (Eudocima spp.) can damage ripening fruit in tropical regions, leading to secondary fungal infection. Net fruiting trees or harvest slightly early in areas with known moth pressure.

Most khirni issues are care-mismatch, not bad luck. Dial in the basics:
