Weeping cherry trees are a spring flowering variety that is native to Japan. Most varieties are hardy in USDA growing zones 5 through 8. These are the recommended areas for best tree growth. Plant the weeping cherry trees in a location that offers full sun and well-draining soil. Proper care of the tree will prevent damage and disease and allow the tree to grow to its full potential.
Fertilize a weeping cherry tree lightly in the spring season with a slow release fertilizer. Fertilizer will promote tree health and assist with disease prevention.
Prune weeping cherry trees in the winter dormant months. The purpose is to thin the branches to let light into the center of the tree by retaining the weeping appearance. Remove dead, diseased and damaged branches.
Remove fallen branches and destroy any leaves and branches that present signs of disease throughout the growing season.
Apply water at the base of the tree when the soil moisture is dry 3 inches down. Use a trickle or drip application to create a slow saturation of water into the soil. Do not over water as the weeping cherry is susceptible to root rot.
Monitor the trees for insect infestation and damage. Apply horticultural oil during the dormant season to control a scale insect problem.
Monitor trees for disease problems. Remove and destroy infected branches and leaves to prevent the spread of disease. Dry weather promotes bacterial infections, while wet weather promotes fungal infections.
