Culture
Best grown in medium moisture, well-drained, acidic loams in full sun. Adapts to a wide range of soils. Established trees have some drought tolerance. Although some flowers may be lost, it is best to prune this tree as needed in late winter. Spring pruning should be avoided as it produces fresh, open cuts where fireblight bacterium can enter.
Noteworthy Characteristics
Malus is a genus of about 35 species of deciduous trees and shrubs from Europe, Asia and North America.
Genus name from Latin is an ancient name for apple.
'Snowdrift' is a rounded, deciduous tree which typically grows 15-20' tall (infrequently to 25') with a similar spread. Red buds open to slightly fragrant, single white flowers (1 3/4" diameter) in spring. Flowers are followed by masses of small, orange-red crabapples (to 3/8" diameter) which mature in the fall. The fruits are persistent and attractive to birds. Ovate, glossy, dark green leaves.
Problems
The main diseases of crabapple are scab, fire blight, rusts, leaf spot and powdery mildew. Potential insect pests are of lesser concern and include tent caterpillars, aphids, Japanese beetles, borers and scale. Spider mites may occur.
'Snowdrift' reportedly has some susceptibility to both fireblight and scab.
Uses
Plant as a specimen/accent or in small groups. General landscape use.
