Pink Spires 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.

Crabapples are also useful as median trees where the fruit will fall away from pedestrians. Placed in the lawn area as an accent so they receive occasional irrigation, Crabapple will give you years of wonderful flowers and showy fruit. It is best to locate them away from a patio or other hard surface so the fruits will not cause a mess. Set it back just far enough so the crown will not overhang the walk, but close enough so the flowers and fruit can be enjoyed. Pink Spires grows in moist, well-drained, acid soil in full sun locations for best flowering. They are not recommended for sandy soil due to their inability to tolerate drought, but any other soil is suitable, including clay.  [1]
