Difficulty: Moderately Easy

Instructions

Things You'll Need:

• Flowering Crab Apple Tree
• Shovel
• Knife or garden shears
• Water
• Mulch or other organic material

1. Choose a planting location. Crab apples thrive in full sun locations with well-drained slightly acidic soil. Eight to 12 hours of direct sun light is recommended for optimal flower and fruit formation.

2. Prepare the tree for planting. Remove any twine or wire and cut burlap away from at least half of the root ball. Containerized specimens should be removed carefully by laying the container on its side, gently tapping with a shovel to help release it, and easing the tree out of the pot.

3. Dig the planting hole at a depth equal to that of the root ball and four times as wide.

4. Position the crab apple in the planting. Backfill several shovels of soil into the bottom of the planting hole to keep the tree straight. Fill the planting hole with water and allow the soil and root ball to absorb. Backfill the remaining soil and water again deeply.

5. Spread a layer of mulch at least 2 to 4 inches deep around the tree. Be careful to mound the mulch too high on the trunk. Wet mulch can cause damage to the trunk bark.

Tips & Warnings

• The flowering crab apple is a deciduous tree or shrub that is hardy in zones four to eight. Some cultivars may be hardier so check the plant's tag for the suggested USDA Hardiness Zone of your chosen plant.
• Flowering crab trees benefit from a weekly watering of 1 to 1 1/2 inches and fertilization in early November. This is particularly important during the first 10 years of planting.
• Crab apples frequently sprout stems called "suckers" at the base of the trunk. Cut them back to the ground at any time during the growing season to keep your tree looking neat.
• If purchasing a bare root specimen, plant in early spring to avoid stress on the tree. Most flowering crab apples, however, are purchased balled and burlapped or in containers. These can be planted almost any time during the growing season but at least three weeks before the ground freezes in the fall. Be sure to give the plant a good soaking in late fall.
• Pick a specimen appropriate for your planting site. Flowering crab apples are available in a wide variety of heights and growing habits. At maturity, the tree ranges in height from eight to 40 feet, but most are from 15 to 25 feet high.
