Establishment
First 1-2 yearsYoung sapling with developing root system and initial branching structure
Water regularly to establish roots. Apply 2-3 inches of mulch around base, keeping it away from the trunk. Stake if necessary in windy locations. Avoid fertilizing excessively
Juvenile Growth
2-4 yearsTree develops stronger branching pattern and increases in height and canopy width. May begin flowering sporadically
Continue consistent watering. Prune only to remove crossing or damaged branches. Maintain mulch layer. Allow natural form to develop
Flowering
2-3 weeks in springIn spring (March-April in most zones), abundant pendulous white bell-shaped flowers appear on branches before leaves emerge
No pruning during bloom. Ensure adequate moisture as flowers develop. Do not remove spent flowers unless necessary for appearance. Support weaker branches if flower load is heavy
Fruiting & Summer Growth
4-5 monthsAfter flowers fade, distinctive four-winged fruits develop and mature throughout summer. Foliage is lush and green
Water during any drought. Monitor for pests and diseases. Minimal pruning needed. Fruits add late-season interest and provide food for wildlife
Fall & Dormancy
2-3 monthsFoliage turns golden yellow before dropping. Tree enters dormancy in winter with visible branching structure and persistent dried fruits
Reduce watering after leaf drop. Mulch heavily if in colder zones for winter protection. No pruning in fall; prune in late winter if needed before spring growth
