Establishment
First 12 monthsYoung sapling with developing root system and initial branch structure
Water deeply and frequently (2-3 times weekly). Apply 2-3 inches of mulch around base. Avoid fertilizing in first year; let roots establish. Support with stake if needed in windy locations.
Juvenile Growth
Years 2-5Tree growing taller and wider, developing multiple branches and denser foliage
Continue regular watering. Prune only to remove dead/crossing branches or establish structure. Apply balanced slow-release fertilizer in early spring. Maintain 2-3 inch mulch layer.
Pre-flowering
Years 5-8Tree approaching maturity with fuller canopy and thickening branches
Reduce watering frequency as root system deepens. Prune lightly to shape. First flowers may appear; these are normal and should not be forced.
Flowering
2-3 weeks in springAbundant deep purple-pink flowers bloom on bare branches in early spring (March-April), followed by leaf emergence
Do not prune during or immediately after flowering. Light pruning only after flowering if needed. Avoid fertilizing right before bloom to prevent excessive leaf growth at expense of flowers.
Mature
Year 10+ ongoingFully formed tree with excellent branching structure, dense dark green summer foliage, and consistent heavy flowering each spring
Water during established drought conditions. Minimal pruning needed; remove dead wood or improve shape. Apply thin layer of mulch if needed. Once established, requires minimal maintenance.
