🌾 Cultivation & Care
| Fertilizer Schedule | Monthly; high potassium and nitrogen; 3 major applications |
| Recommended Organic Fertilizers | FYM, vermicompost, neem cake, wood ash, banana peel compost |
| Pesticide Frequency | Monthly preventive; treat immediately if pests appear |
| Recommended Organic Pesticides | Neem oil for aphids and thrips; Trichoderma for Fusarium wilt |
| Mulching Practice | Heavy organic mulch to retain moisture and suppress weeds |
| Training System | Desuckering — keep 1 mother plant + 1 follower sucker |
| Pruning Time | Remove dry leaves regularly; cut pseudostem after harvest |
| How to Prune | Cut pseudostem at ground level after harvest; remove dry leaves; desuck regularly |
| Common Pests | Banana weevil, thrips, aphids, nematodes |
| Common Diseases | Panama wilt (Fusarium), Sigatoka leaf spot, bunchy top virus |
