Crabapples are a popular small tree for urban and suburban landscapes. Flowers, produced in early spring, are white, pink or red. The purple leaved Crabapple produces color best in full sun. Fruit varies in size and color and may cling to twigs in winter to provide food for
wildlife. If you’re looking for just the aesthetics there are non-fruit bearing verities of the Crabapple. It is important to take into consideration, these trees can also be host to many insects and pests, including caterpillars, aphids, scale insects and spider mites.
The key to successful pest and disease management is a plant healthcare program in early (mid-April to late May).

resistant varieties are available and should be used to reduce the impact.
