Heat Stress Is Causing Premature Leaf Drop on San Antonio's Cedar Elms Right Now

Post Copy

Cedar elms across San Antonio are losing leaves weeks early this month, and prolonged heat and water stress is usually the reason rather than disease.

Shedding leaves early is a defense mechanism that lets the tree cut water loss when the ground cannot keep up with demand during a stretch of high temperatures.

Most cedar elms bounce back with consistent deep watering at the root zone, though repeated stress year after year can leave a tree more vulnerable to pests or disease down the line.

San Antonio homeowners seeing early leaf drop can request a professional look to rule out anything more serious than heat stress.
