Crabapples are among the most popular spring flowering trees. They’re adaptable to a range of soil types. Buds for the next season will set in mid-summer, so prune in early June if needed. Suckers should be removed and pruning the center of the plant to encourage air movement can help prevent disease problems. Selkirk is especially winter hardy, resistant to damage from late spring frosts. Single to semi-double rose red flowers. 4/5 inch glossy purple-red fruit. Foliage emerges reddish-green.
