Much like other trees and shrubs, a weeping cherry tree has its fair share of natural enemies. If you plan on incorporating these decorative trees into your yard’s landscaping, keep in mind that you may have to give them some extra care to keep them healthy. Bugs are one of the biggest natural enemies for trees. They enjoy burrowing and nesting inside various areas of trees, and many different plants make great food for certain bugs. Japanese beetles in particular like the weeping cherry tree, so consider treating your new trees for these particular bugs. Aphids and tent caterpillars also make homes inside cherry trees. Treat your tree for aphids and simply knock down tent caterpillars if their nests become an unsightly distraction in your yard. Keeping your tree properly watered is also essential. Keeping your tree at the right moisture level can prevent bug infestations, so ensure it is watered, but not overwatered.
