Establishment
Year 1-2Young tree with thin, upright branches gradually beginning to weep; sparse foliage; small pink or white flower buds appear in early spring
Water regularly to establish deep root system. Apply 2-3 inches of mulch around base. Stake if necessary to support drooping growth. Prune minimally.
Branch Development
Year 2-4Branches elongate and weeping habit becomes more pronounced; fuller canopy emerges; annual spring flowering becomes more abundant
Continue consistent watering. Shape canopy by removing crossing or damaged branches. Thin crowded interior branches to improve air circulation. Fertilize lightly in early spring.
Flowering
2-3 weeks in springProfuse double pink or white blossoms cover branch tips in mid to late spring; flowers open before or as leaves emerge
Maintain consistent moisture. Do not prune during flowering. Enjoy display for 2-3 weeks. Deadheading spent flowers improves appearance but is not essential.
Foliage & Growth
Late spring through early fallDense green foliage on drooping branches; tree reaches full weeping form; occasional secondary flowering may occur in fall
Water during dry periods. Monitor for pests and diseases. Prune only to remove dead wood or shape canopy. Apply balanced fertilizer in early spring if needed.
Dormancy
Late fall through early springLeaves turn yellow to reddish-brown and drop; bare weeping branches create sculptural winter silhouette; buds form for next season
Reduce watering significantly but do not allow root ball to dry completely. No fertilizing. Inspect for winter damage or pests. Prune dead or diseased wood in late winter before growth resumes.
