| Recommended Organic Fertilizers | FYM (25–50 kg/tree/year), neem cake, vermicompost |
| Pesticide Frequency | Minimal; generally pest-resistant |
| Recommended Organic Pesticides | Neem oil for leaf miner; fruit fly traps during fruiting |
| Mulching Practice | Organic mulch around base; leaf litter provides natural mulch |
| Training System | Modified central leader; natural form for mature trees |
| Pruning Time | After harvest (August–September) |
| How to Prune | Remove dead and crossing branches; thin canopy for light and air |
