Conseils de culture
Use fresh neem seeds for planting as viability drops rapidly; seeds lose germination capacity within 2-3 weeks of collection.
Trees begin fruiting from year 3-5; full production reached at 10 years with yields increasing annually.
Collect fallen fruits promptly and depulp immediately; delayed processing reduces azadirachtin content in seed kernels.
