Crabapples are versatile, small, ornamental trees used in
the urban landscape. Crabapples bloom in spring, usually in
May, bearing flowers that vary a great deal in color, size,
fragrance ,and visual appeal. It is common for flower buds
to be red, opening to pink or white flowers. The fruit
ripens between July and November, and varies in size from ¼
to 2 inches long or wide. Crabapples thrive in full sun and grow best in well drained, slightly acidic soils (pH 5.5-6.5); however, they will grow well in many soil types. Most crabapple selections tolerate the cold winters and hot, dry summers prevalent in the Midwest. For many years, crabapple cultivars have been selected on the basis of their flowers, but with some cultivars, undesirable features, such as disease problems and early fruit drop, outweigh their short-lived spring beauty. No single cultivar can fulfill every landscaping need. Consider the following information when choosing a crabapple cultivar for your landscape. [3] |

Dolgo crabapple requires very little
pruning but any that is needed should be completed before
late spring, to ensure dormant flower buds are not removed.
Trees used as street trees should be trained to develop a
central trunk and should be occasionally thinned to
eliminate water sprouts or crossed-branches, and to open up
the crown. This allows for better air circulation through
the crown and helps reduce disease. |
