🌾 Cultivation & Care
| Fertilizer Schedule | 2–3 times per year; pre-flowering and post-harvest |
| Recommended Organic Fertilizers | FYM (15–30 kg/tree/year), compost, bone meal, vermicompost |
| Pesticide Frequency | Minimal; generally pest-resistant |
| Recommended Organic Pesticides | Neem oil for occasional aphids or scale; fruit fly traps during fruiting |
| Mulching Practice | Organic mulch around base; leaf litter recycling |
| Training System | Central leader or open center; minimal training needed |
| Pruning Time | After fruiting; shape as needed |
| How to Prune | Remove dead and crossing branches; thin canopy for air circulation; manage spread |
| Common Pests | Fruit fly, aphids, scale insects, Caribbean fruit fly |
| Common Diseases | Rust (Puccinia psidii), anthracnose, leaf spot |
| Disease Prevention & Remedies | Good air circulation, copper fungicides, remove infected leaves, avoid overhead watering |
🌸 Flowering & Fruiting

| Days to Harvest | 60–90 days from flowering |
| Harvest Indicators | Fruit turns pale yellow, strong rose fragrance, slight give when pressed |
| Average Yield per Plant | 200–400 fruits per tree (mature); consistent bearer |
| Pollination Type | Self-fertile; cross-pollination by bees improves yield |
