Crabapples have diverse growth habits or tree shapes. The shapes consist of weeping (pendulous), rounded, spreading (horizontal), upright (columnar), vase-shaped, and pyramidal. Flowering crabapples vary greatly in size. At maturity, certain cultivars will only attain a height of eight feet, while others will tower to heights greater than 40 feet. However, most flowering crabapples reach mature heights of 15 to 25 feet.
Due to their versatility, crabapples make excellent choices for use around homes, schools, parks, public and commercial buildings, and in highway plantings. Tree health and vigor depends upon proper site selection and preparation. Before planting, have the soil tested to assure proper pH and nutrient levels. If necessary, make any adjustments to the soil before planting.
Every effort should be made to keep roots or the root ball from drying out before planting. For bare root trees, the planting hole should be dug wide and deep enough to allow for the natural extension of the root system. None of the roots should be cramped or bent to fit into the hole. This can result in girdling (strangling) roots that will slowly kill the tree. Damaged roots should be pruned just above the break or damaged area prior to planting.
