Weeping cherry trees can add a graceful elegance to a landscape. These ornamentals burst with white or pink blossoms in the spring, followed by dark-green foliage in late spring through the fall. Weeping cherry trees grow best in zones 4 to 8. They can grow 20 to 40 feet tall with an overall spread of 15 to 30 feet. Weeping cherry trees are deciduous; they loose their leaves in the late fall, leaving a distinctive winter silhouette.
Plant the weeping cherry in an area that enjoys full sun and moist, well-draining soil. Plant the weeping cherry near the water for its reflective and moisture values, if you have a pond, lake or other areas of water on your property.
Dig a hole in early spring that's as deep as the weeping cherry tree growing container and twice as wide. Add a 1-inch layer of ornamental tree fertilizer to the bottom of the hole. Fill in around the tree with potting soil or backfill it with the removed soil if it is good quality.
Create a 3-inch deep organic mulch bed around the base of the weeping cherry tree. Extend the bed in a 4- to 6-foot perimeter from the trunk. Extend the mulch bed as needed to match the circumference of the tree.
Keep the soil around the tree moist. Water three to four times each week, more often during drought conditions. Frequent watering helps the tree become more disease resistant.
Prune the weeping cherry tree in the early spring or late fall when the tree is still dormant, when no leaves or flowers are present. Trim back the tips of any branches that touch the ground so that they are at least 6 inches from the ground.
Remove any branches that are growing straight up, as these will not curve if the weeping cherry tree has been grafted. Do not cut the straight branches, as these will eventually curve if the weeping cherry tree is natural. Grafted trees have a graft knot near the crown.
Cut away any dead branches. Remove one of any two brances that cross each other.
Fertilize weeping cherry trees lightly each spring with an ornamental tree fertilizer. Follow the directions on a 3 lb. bag of fertilizer to cover the ground around a mature tree.
