| Recommended Organic Fertilizers | FYM, compost, neem cake, bone meal |
| Pesticide Frequency | Minimal; generally pest-resistant |
| Recommended Organic Pesticides | Neem oil for occasional caterpillar or scale infestations |
| Mulching Practice | Organic mulch around base; leaf litter serves as natural mulch |
| Training System | Central leader or natural form |
| Pruning Time | After harvest or during dormancy |
| How to Prune | Remove dead and crossing branches; thin canopy for light penetration |
