Seedling
2-3 monthsGerminated seed develops first true leaves and establishes root system; very young plants are fragile and small
Keep soil consistently moist; provide bright indirect light; protect from direct sun and wind; use well-draining seedling mix
Vegetative Growth
2-4 years from seed (much shorter from grafted stock)Young tree develops stem and foliage; gradual height and branch development; no flowering yet
Water regularly; gradually increase sun exposure; apply balanced fertilizer monthly; stake for support if needed; mulch around base
Maturation
1-2 yearsTree reaches productive size with full canopy; branches thicken and extend
Maintain consistent watering; reduce nitrogen fertilizer to encourage flowering; prune for shape and air circulation; continue mulching
Flowering
Several weeks, multiple flushes possibleSmall white or pale pink fragrant flowers appear on branch tips; flowers are followed by fruit set
Ensure adequate moisture during bloom; reduce disturbance; monitor for pests during flowering; light fertilizer with higher phosphorus promotes fruiting
Fruiting & Harvest
4-8 weeks per crop; may produce multiple crops annuallySmall reddish-purple fruits develop over several weeks; fruits mature and soften; ready for harvest when slightly yielding to pressure
Maintain consistent watering during fruit development; thin crowded fruit if desired for larger fruits; harvest ripe fruits promptly; support heavy-laden branches

Ripe fruits can be stored refrigerated for a few days. In Hawaii, peak harvest typically occurs in late summer through fall, though trees may produce multiple crops.
