Establishment
1-2 yearsYoung tree focuses on root and branch development with minimal flowering
Plant in spring or fall; mulch around base; water regularly; protect from harsh winds; stake if necessary
Vegetative Growth
1-3 yearsTree develops strong scaffold branches and canopy structure; leaf growth is vigorous
Prune to establish open-center or central leader form; thin competing branches; maintain consistent watering; apply balanced fertilizer in spring
Flowering
2-4 weeks in springFragrant white flowers appear in clusters in spring before or with leaf emergence
Flowers are self-fertile but benefit from cross-pollination; thin excessive flower buds if over-flowering; protect from late frosts
Fruit Development
8-12 weeksSmall green fruits develop and gradually enlarge; ripen to golden-yellow in late summer
Thin fruits to 4-6 inches apart for larger fruits; maintain consistent watering during fruit set; reduce nitrogen fertilizer to avoid excessive vegetative growth
Harvest & Dormancy
Variable; dormancy 3-4 monthsFruits mature to full color; tree enters dormancy after leaf drop in autumn
Harvest when fully colored; prune in late winter while dormant; minimal watering in winter; remove dead wood

Harvest Tips
Harvest in late August through September when fruits are fully golden-yellow and slightly soft to gentle pressure. Pick fruits by hand or allow to drop into collection cloths. Fruits continue to ripen slightly after picking. Store in cool conditions (32-40°F) for extended shelf life. Young trees may produce fewer fruits; yields increase with maturity.
