Quick-growing, hardy, and offering ample shade, the American chestnut tree is an impressive species. However, these trees do need some ongoing attention. From tree trimming to watering, find out how to properly care for your American chestnut tree.
Have the Tree Pruned Annually
American chestnuts have been a prized property addition for years because the trees offer several feet of growth annually. While growth will slow as the tree matures, it is still important to have the tree trimmed annually to keep it in good shape. Chestnut trees rely on resources around them to feed their rapid growth. Therefore, the larger the tree, the more resources the tree will need to live, and the more resources will be pulled away from other parts of your landscape.
Make Sure Your Chestnut Tree Gets Ample Water
Chestnut trees need an ample amount of water to thrive, especially in areas where temperatures run relatively high. Even though this tree species likes good drainage and generally loamy soil, the tree roots absorb a substantial amount of water to support growth. Therefore, they do best in an environment in which there is ample rainfall or regular watering. It is a good idea to water a chestnut tree about once a week with a gallon of water, but the tree may need more than once-weekly watering during high-temperature periods.
Watch Out for Problematic Pests
While the American chestnut tree is a relatively hardy tree species, this tree is not immune to its own collection of pests. Several hungry insects find the chestnut tree attractive, even if the tree is not bearing fruit. The chestnut can be prone to both tree-specific pests like the Asian chestnut gall wasp and general pests like Japanese beetles and weevils. Pay close attention to the tree's health from season to season. Additionally, stay in tune with what pests could be most threatening in your area. Watch for signs of pests like dying areas of foliage, bored holes in the trunk, and missing bark. Talk to a tree service professional if you spot an issue.
Keep Other Plants and Growth Away from the Base
American chestnut trees are not picky growers, but they do like their space. Work with a tree trimming professional to make sure any smaller trees around the chestnut are kept trimmed to a small size. In general, any larger tree should be removed so resources are reserved for the chestnut tree.
