Culture Notes This large shrub or small tree tends to leaf out early, so it may be injured by spring frosts. Protect them from drying winds and direct sun by providing exposure to partial or filtered shade and well-drained, acid soil with plenty of organic matter, particularly in the southern part of its range. Leaves often scorch in hot summer weather in USDA hardiness zones 7b and 8, unless they are in some shade or irrigated during dry weather. More direct sun can be tolerated in the northern part of the range. Be sure drainage is maintained and never allow water to stand around the roots. Grows fine on clay soils as long as the ground is sloped so water does not accumulate in the soil. Responds well to several inches of mulch placed beneath the canopy. Holds red foliage color well in summer in the south.

Prune early in the life of the tree to develop several major branches well-spaced along a central trunk. This will improve the durability of the tree compared to trees with many upright and spreading branches originating from one point on the trunk.

Pests and Diseases Aphids, scales and borers can be found on the Maples. Scorch occurs during periods of high temperatures accompanied by wind. Verticillium wilt can kill plants.
