Help for dogwood health
What can I do for the health of my 35 to 40 year old dogwood? The tree is about 25 ft tall. The bark and rot problem started 18 months ago. It receives full sun, windy conditions with salt spray. The Ivy has been removed from the base of the tree. How can I save my tree that has given me so much pleasure?
The dogwood tree appears to have extensive bark damage and possibly boring insects. There really isn't anything you can do to repair or cure that amount of damage and decay in the trunk. The tree is in decline and cannot recover from this amount of decay. The best you can do would be to keep the tree watered during dry periods and just enjoy it while it lasts as it declines naturally. If it is near a structure, you might want to have it taken down. https://extension.umd.edu/learn/how-do-you-decide-when-remove-tree
