Planting & Care

Choose a sunny or partially shaded spot and amend the planting hole with compost and general-purpose fertilizer, then mulch the base to retain moisture. Water only when weekly rainfall falls below one inch, as overwatering can cause yellowing leaves. Apply general-purpose fertilizer each spring to support vigorous growth and abundant flowering. Light pruning in early spring helps shape the tree or control its size; remember that taller specimens naturally produce smaller blooms. Once established, this tree requires minimal attention and rewards you with spectacular color season after season.
