Bacterial leaf scorch is a potentially fatal disease for trees. Luckily, proper tree care can mitigate damage and extend the life span of affected vegetation. If you’ve noticed that a tree on your property consistently has browning leaves before the others, it might be affected by this condition. Here’s what you need to know.

What Is Leaf Scorch Disease?

Spittlebug and leafhopper insects spread bacteria known as xylella fastidiosa between trees. These bacteria affect tissues that carry water and nutrients, meaning leaves may not receive what they need. As a result, leaves turn brown at the edges, forming yellow or reddish-brown borders. 

Symptoms first appear in mid-summer, worsening throughout late summer and fall. The condition slowly progresses over a period of around three to eight years, with more leaves turning brown prematurely each year. Eventually, there are no healthy leaves that produce chlorophyll, leading to tree death. Many species are affected by bacterial leaf scorch, including oak, sweetgum, elm, mulberry, red maple, and sugar maple trees.

How Do Professionals Manage It?

tree careBranches affected by leaf scorch must be trimmed to stop the spread of bacteria. If most of the tree is impacted, a professional may choose to remove the tree to protect surrounding growths.

Alternatively, tree care technicians can prolong the life of an infected plant by injecting it with antibiotics in the spring. These products reduce or delay symptoms, but don’t cure the disease. They must be reapplied each spring to remain effective.
