Nursery days
Planting: Plant at onset of rains or irrigate; use healthy seedlings/grafts; incorporate compost and starter P.
Transplanting: Stake young trees; mulch; protect from wind; maintain weed-free basins.
Irrigation: Keep evenly moist, especially from flowering to fruit fill; avoid drought to limit fruit drop.
Fertigation: Split N into light feeds; supply K and Ca during fruiting; adjust via soil/leaf tests.
Pest scouting: Scout for fruit flies, mealybugs/scales, anthracnose; prune to open canopy; sanitize fallen fruit.
Pruning/Training: Form an open center or modified leader; remove crossing and shaded interior wood.
Harvest: Harvest when spines flatten and fruit turns dull green; handle carefully; climacteric—ripens off tree.
Postharvest: Cool promptly; short shelf life (3–5 days at ambient); store 10–15 °C at high RH; minimize bruising.

Fruit flies (Tephritidae) pest Stings; larval tunnels; fruit drop Protein baiting, field sanitation, fruit bagging, timely harvest
Mealybugs & scales pest Honeydew; sooty mold; twig decline Prune for airflow; control ants; oils/soft insecticides; conserve predators
Anthracnose (Colletotrichum) disease Leaf/fruit lesions; postharvest decay Open canopy; protectants in wet periods; careful handling
Phytophthora root/collar rot disease Cankers; wilting; tree decline Excellent drainage; avoid trunk wetting; phosphonates if needed
Fruit borers (Lepidoptera) pest Bored fruit; frass Field sanitation; bagging; targeted control
