Establishment
1-2 yearsYoung tree is small with thin trunk and initial branch development; tree focuses on root system establishment
Water regularly to keep soil moist; provide light staking for support; avoid heavy fertilization in first year; prune out damaged branches
Vegetative Growth
2-4 yearsTree rapidly increases in height and canopy spread; develops characteristic compound leaves and dense foliage; no flowering occurs
Maintain consistent watering; apply balanced fertilizer every 3-4 months; prune to shape canopy; remove crossing or crowded branches; mulch around base
Maturation
Ongoing after year 4Tree reaches full size (25-40 feet); canopy becomes dense and full; begins producing small flower panicles
Reduce nitrogen to encourage flowering; ensure good drainage during monsoon season; prune selectively to maintain shape; continue regular fertilization with balanced NPK
Flowering
4-8 weeksSmall greenish-yellow flowers appear in terminal panicles in spring (February-April in Northern Hemisphere); flowers are fragrant and attract pollinators
Reduce watering slightly to promote flower set; avoid heavy fertilization during flowering; monitor for pests; provide pollinator habitat; do not prune during this stage
Fruiting & Harvest
3-4 months from flowering to harvestSmall round fruits develop, progressing from green to yellow-brown to red-brown when ripe; fruit develops distinctive bumpy texture; flesh becomes translucent and sweet
Thin fruit clusters if desired for larger individual fruits; maintain consistent watering; support heavy branches; harvest when fruit shows red-brown coloring and skin texture develops
