| Spacing | 8–12 meters between trees |
| Irrigation Method | Basin irrigation; minimal once established |
| Water Requirement | Low to moderate; drought-tolerant once established |
| Can it Grow in Pots? | Young grafted trees in large pots (50+ liters); not ideal long-term |
🌾 Cultivation & Care
| Fertilizer Schedule | 2–3 times per year; pre-monsoon and post-harvest |
| Recommended Organic Fertilizers | FYM, vermicompost, neem cake, bone meal |
| Pesticide Frequency | Minimal; generally pest-resistant |
| Recommended Organic Pesticides | Neem oil for leaf miner; fruit fly traps |
| Mulching Practice | Organic mulch around base |
| Training System | Modified central leader; natural form |
| Pruning Time | After harvest (August–September) |
| How to Prune | Remove dead and crossing branches; thin canopy for light |

🌱 Pollination & Propagation
| Pollination Details | Insect-pollinated; fragrant flowers attract bees and flies |
| Propagation by Seeds | Seeds may not produce true white-fruited plants; grafting preferred |
| Propagation by Cuttings | Difficult; air layering possible but slow |
