Crabapple trees are small ornamental apple trees known for colorful blossoms, tiny fruits, and attractive foliage. They are popular in gardens because they bloom beautifully in spring and support pollinators like bees. Crab apples are usually tart but can be used for jelly, cider, and preserves. To grow them successfully, plant them in well-drained soil with full sunlight and enough airflow to reduce disease problems. Water young trees regularly, mulch around the base, and prune dead or crowded branches during dormancy. Most crab apple trees grow best in temperate climates and benefit from seasonal fertilization and occasional pest management.
