Culture Notes
This crabapple grows best and is most disease resistant in full sun. It will adapt to varying soils including sandy sites and clay as long as the location does not have standing water during the winter. Once established it is drought tolerant. This selection was chosen for its superior disease resistance in the maritime Pacific Northwest. Prune young trees for good branch structure. Older trees should have limited pruning only to remove dead, broken or poorly formed branches. Pruning this tree can be tricky for the beginner so consult an experienced pruner or take local classes before attempting to prune.
