New England's diverse and lush landscape is home to a wide variety of tree species, providing beauty, shade, and ecological benefits to the region. However, trees in this area are also susceptible to various diseases that can impact their health and vitality. Identifying and understanding common tree diseases is crucial for early detection and effective treatment.
In this blog post, Wilder's Tree Service will highlight some prevalent tree diseases to watch out for in New England, enabling homeowners to protect their trees and preserve the natural beauty of the region.
Dutch Elm Disease: Dutch Elm Disease is a devastating fungal infection that affects American and European elm trees. It is spread by elm bark beetles and causes rapid wilting, yellowing, and browning of leaves, ultimately leading to tree death. Early detection and prompt management are vital to prevent the spread of this disease.
