Establishment (Years 1-2)
2 yearsYoung tree develops root system and main scaffold branches; minimal flowering
Water regularly, mulch well, prune to shape framework, avoid heavy fertilizing that encourages vegetative growth over roots
Juvenile (Years 2-3)
1-2 yearsTree reaches 6-10 feet; flowering begins but fruits are typically removed to strengthen tree
Allow some flowering; pinch off most developing fruits to redirect energy to growth; continue shaping; apply balanced fertilizer monthly
Flowering
2-4 weeksTerminal panicles of small yellowish-white flowers appear in late winter to early spring; light, fragrant blooms
Ensure adequate potassium; avoid excessive nitrogen; reduce water slightly to encourage flowering; protect from frost if temperatures drop below 32°F
Fruiting & Development
3-5 monthsMarble-sized fruits develop and enlarge over 3-4 months; skin color transitions from green to golden-yellow when ripe
Thin fruits to 1 every 6 inches for larger specimens; maintain consistent watering; apply zinc foliar spray if yellowing appears; monitor for pests
Harvest
2-4 weeksFruits reach 10-16 oz, golden color, and emit sweet fragrance; flesh yields slightly to pressure
Harvest when skin color is predominantly golden and fruit detaches easily with gentle twist; place in paper bag to finish ripening if picked slightly early

Harvest Tips
Mangoes mature 3-5 months after flowering. Harvest when fruit develops full golden color and yields slightly to gentle pressure; a sweet fragrance at the stem indicates ripeness. Twist gently or cut with pruning shears, leaving 1-inch stem attached. Handle carefully to avoid bruising. Fruits will continue ripening off-tree and store 1-2 weeks at room temperature or 2-3 weeks refrigerated. Peak harvest occurs June-August in most U.S. growing regions.
