Seedling/Young Tree
1-2 yearsSmall tree with emerging compound leaves, developing main trunk and primary branches
Keep soil consistently moist during first growing season; provide mulch layer 2-3 inches deep; protect from extreme heat and wind stress; stake if necessary for stability
Vegetative Growth
5-15 yearsRapid height and width development; vigorous leafy growth during growing season; strong branch formation
Water during drought periods; prune for shape and structure; thin crowded branches to improve air circulation and light penetration; fertilize lightly if needed
Flowering & Seed Production
Spring flowering; seed maturation by September-OctoberSmall purple flowers appear on branches in spring before or as leaves emerge; flowers develop into winged seed pods (samaras) by late summer/fall
No special care needed; allow natural seed development if tree self-seeding is desired; deadhead seeds if volunteer seedlings are unwanted
Mature Tree
20+ yearsFully developed 45-55 foot tall tree with broad canopy; established root system; regular annual flowering and fruiting cycle
Minimal watering once established except during severe drought; occasional pruning to remove dead or crossing branches; monitor for diseases; provide adequate spacing from structures and utilities
