Weeping cherry trees provide a graceful sweeping effect in your landscape. These attractive trees maintain a small size in the yard, reaching a mature height around 25 feet and a width near 20 feet. These trees produce masses of light pink blossoms in the spring, adding a burst of soft color to your landscape. Unfortunately, weeping cherry trees can suffer from a variety of conditions that cause drooping and wilting. Rejuvenating a wilting tree requires determining the cause of the problem and following a proper course of treatment.
Ensure Adequate Moisture
Like other types of plants, weeping cherry trees require adequate amounts of moisture to survive and flourish in your landscape. These trees enjoy slightly moist, well-drained soils. Encourage healthy growth by watering thoroughly when the soil becomes slightly dry near your tree’s upper roots. Water long enough to soak the entire root ball. Allow the soil to dry out before watering again. Too much water, or drowning the roots, can also cause your weeping cherry tree to wilt.
Keep the Area Clean
Rake up fallen blossoms, leaves and vegetation from the soil surrounding your tree. Remove rotting fruits as they fall from your tree. Decomposing vegetation can create the ideal environment for bacterial diseases, such as bacterial canker and crown gall. In addition to causing wilting, these bacterial diseases can turn leaves a dark brown and cause leaves to wither and fall from your tree, according to Washington State University Extension.
Weeping cherry trees can suffer from a variety of pest infestations, including the granulate ambrosia beetle. The U.S. Department of Agriculture first detected this destructive beetle in 1992. It attacks a variety of susceptible trees, including weeping cherry trees. This beetle begins damaging your tree by digging beneath the bark. An affected tree may appear wilted and show signs of holes along the trunk and limbs. Protect your tree with an application of pesticide that controls boring insects and bark beetles. Bifenthrin, chlorpyrifos and permethrin contain ingredients that help protect your tree against granulate ambrosia beetles, according to the Indiana Department of Natural Resources.
Boost Soil Nutrients
Soil can begin to show signs of nutrient depletion. A tree that fails to grow produces few blossoms and begins to show signs of wilting may be suffering from lack of nutrients. Select a fertilizer labeled for use on weeping cherry trees. Apply the fertilizer according to the instructions. Following a regular fertilization schedule may reduce wilting and improve the overall health of your tree.
