If the leaves on your pin oak or red oak browned at the edges long before fall color arrived, bacterial leaf scorch may be the reason.
This disease is common across Arlington, Alexandria, and Washington DC. It clogs the tree's water-conducting tissue, causing leaf browning with a yellowish band between the scorched edge and the green center. It tends to reach more of the crown each year. Symptoms appear from late summer into fall and can be mistaken for drought stress or early autumn color.
There is no cure, but the disease usually moves slowly. Proper watering, mulching, and removal of dead branches can keep an infected oak safe and attractive for years. Some trees also respond well to targeted treatments that slow the decline.
Fall is a good time to confirm what you are seeing. We enjoy walking homeowners through the signs so they understand exactly what is happening with a tree they care about.
