Weeping cherry trees can grow as high as 30 to 40 feet. Some will have a spread equal to or larger than its height, depending on the type. These are beautiful trees, covered in pink to almost white flowers in the spring. Weeping cherries are one of the most popular landscape trees especially for those with ponds or lakes as the trees are stunning planted near water. These trees are not known for longevity, but they require little care and pruning.
Stake a newly planted tree with a wooden stake, using loosely tied landscape ties to attach it. Do not use metal twist ties as the tree is fast growing and the twist ties can damage the trunk if too tight. Leave the tree staked until it can support itself in windy conditions but no longer than the first year.
Water the tree twice a week after planting for the first month. Then cut back to once a week throughout the first growing season. Long, slow watering is more advantageous as it develops a deeper root system. Irrigate when the weather conditions are hot and dry for more than a week in subsequent seasons.
Spread a 2-inch deep layer of mulch under the canopy of the tree. Keep the mulch 6 inches from the tree trunk and hand pick any weeds in that area. The mulch will keep weeds from growing in the area and help to retain moisture for the root system.
Apply a rose fertilizer once you start to see growth on the tree and again after flowering. Do not fertilize in the fall as this may cause the tree to bud too early. Follow manufacturer's directions on the amount to apply.
Cut away any sprouts below the graft line of the tree. Allow the tree to grow through the first season only cutting dead or damaged branches and sprouts below the graft line. Once the branches start to bend down to the ground, cut off any part of the branch that is touching the ground.
Trim branches that are rubbing against other branches to prevent damage and disease. Cut back any branches at the top that are growing straight up. As the tree gets thick with branches, trim out some of the interior to allow for proper air circulation.
