If the leaves on a mature oak or red maple look scorched at the edges even though the tree has had plenty of water, bacterial leaf scorch may be the cause, not drought. It's a slow-moving disease that shows up more in the second half of summer, and it's turning up early on trees across Arlington and Northern Virginia this year.
Unlike heat stress, bacterial leaf scorch doesn't resolve with rain or cooler weather. It spreads through the tree's water-conducting tissue over several seasons, gradually reducing canopy density and vigor. Early symptoms are easy to mistake for ordinary summer drought, which is exactly why professional diagnosis matters.
Once identified, management focuses on supporting the tree's overall health and slowing progression, since there's no cure once a tree is infected. Catching it early gives a mature tree the best chance at a longer, healthier life.
If a shade tree on your property has looked off since midsummer, it's worth having a professional take a look before assuming it's just the heat.
