Plant ornamental pear trees in your yard for their lovely spring flowers and relatively easy maintenance. While they do not bear fruit, they do have attractive fall foliage. Ornamental pear trees are also hardier than fruiting pear trees, so they can grow in a wider variety of climates. Some ornamental pear trees are hardy between USDA hardiness zones 3 and 6. Ornamental pear trees are medium-sized trees, growing about 45 feet tall with a 20-foot spread.
Choose a spot in your yard to plant the ornamental pear trees. They like full sun and moist, well-drained soil. Ornamental pear trees can tolerate clay soil as long as it is well drained. They also like slightly acidic soil. If your soil is too alkaline, add sulfur, at a rate of 1 lb. to every 30 square feet, and work it into the soil to a depth of 3 to 4 feet.
Plant ornamental pear trees in the spring after the last frost.
Dig a hole for the ornamental pear trees. Dig the hole 2 inches shallower than the root ball and about 2 to 3 times as wide. Space trees at least 50 feet apart.
Place the ornamental pear trees in the holes. Make sure their root balls are elevated above the soil by 2 inches.
Fill the holes with soil and pat it down firmly. Water the ornamental pear trees for five to 10 minutes.
