Pruning Tips
While Washington hawthorns require minimal pruning, proper training is essential to prevent them from developing into thickets. If pruning is necessary, it is best to do so after blooming or in the fall after the leaves drop. Consider consulting a licensed arborist for pruning thorny hawthorn trees.
