The Siberian crabapple (Malus baccata) is a deciduous, cold-hardy tree. Homeowners plant the tree for its graceful, rounded canopy and the fragrant blossoms that appear in the spring. The red or yellow pea-sized fruit makes tasty preserves. The Siberian crabapple generally grows to a height of 25 feet, with an equal spread, in its USDA hardiness zones, 2a through 7b. Give your Siberian crabapple tree moist soil and lots of sunshine. Plant the tree in the early spring to allow it to become acclimated prior to summer's heat.
Choose a location in which to plant the Siberian crabapple tree, keeping in mind that the fallen fruit can leave a mess. Planting near a driveway, sidewalk or patio may not be a good idea.
Dig a planting hole. It should be 3 times the width of the container in which the tree is growing, and the same depth. Use a gardening fork to poke around inside the hole, scraping the sides and bottom to make it easier for the roots to penetrate the soil.
Remove the Siberian crabapple tree from the pot. If the tree was pot-bound (the roots are wound around and the rootball is compacted), use your fingers to gently loosen them and spread them out.
Place the roots of the Siberian crabapple tree into the planting hole and backfill with the soil you removed. Tamp the area around the base of the plant, using your hands.
Water the tree slowly but deeply, allowing the water to puddle. When the water drains, apply a 3-inch layer of mulch around the tree, keeping it at least 2 inches away from the trunk. This will help to conserve moisture and discourage weeds.
