| Soil Type | Deep, fertile, well-drained loamy to clay-loam soil |
| Soil pH Preference | 5.5–7.0 |
| Sun Requirement | Full sun to partial shade (6+ hours daily) |
| Spacing | 6–8 meters between trees |
| Irrigation Method | Basin or drip irrigation; regular watering during dry spells |
| Water Requirement | High; thrives near water sources and in humid environments |
| Can it Grow in Pots? | Yes, dwarf varieties in large containers (40+ liters) |
🌾 Cultivation & Care
| Fertilizer Schedule | 3–4 times per year; increase before flowering season |
| Recommended Organic Fertilizers | Well-rotted FYM, vermicompost, bone meal, fish emulsion |
| Pesticide Frequency | As needed; monitor during fruiting season |
| Recommended Organic Pesticides | Neem oil, garlic-chili spray, sticky traps for fruit flies |
| Mulching Practice | Thick organic mulch around base to retain moisture; keep away from trunk |
| Training System | Open centre system; allow natural spreading habit |
| Pruning Time | After harvest; remove dead and crossing branches |
| How to Prune | Light pruning to maintain shape; thin interior for air circulation |
| Common Pests | Fruit fly, aphids, scale insects, leaf miners |
| Common Diseases | Anthracnose, sooty mold, root rot, leaf spot |
| Disease Prevention & Remedies | Good drainage, avoid waterlogging, copper-based fungicides, remove fallen fruit |
🌸 Flowering & Fruiting
| Flowering Months | March–May and September–November (twice yearly in tropics) |
| Fruiting Season | May–July and November–January; 30–45 days after flowering |
| Days to Harvest | 30–45 days from fruit set |
| Harvest Indicators | Fruit develops full size, waxy sheen appears, slight give when pressed |
| Average Yield per Plant | 50–100 kg per tree per year (mature tree) |
| Pollination Type | Self-pollination and insect pollination |
| Pollination Notes | Bees and other insects are primary pollinators; wind assists |
🌱 Pollination & Propagation
| Pollination Details | Flowers attract bees with nectar; self-fertile but cross-pollination improves yield |
| Propagation by Seeds | Seeds germinate in 2–4 weeks; seedlings take 5–7 years to fruit |
| Propagation by Cuttings | Air layering (marcotting) is the preferred vegetative method; roots in 6–8 weeks |
| Propagation by Grafting | Approach grafting and budding on Syzygium rootstock for early fruiting |
💧 Environmental Impact & Sustainability
