Sea Grape Leaf Drop: Cold Stress vs. Disease

Do Sea Grapes Shed All Leaves Annually?

Only if temperatures drop below freezing. Otherwise, they shed partially, retaining some foliage.

Diagnosing the Cause

Cold stress and fungal disease look similar in winter—both cause discoloration and leaf drop. Wait until spring. New growth will reveal the truth: healthy emergence means cold stress; stunted, spotted new growth indicates disease.

If Problems Persist

Take a sample (leaves + stem) to your local Cooperative Extension Service for lab analysis. Even pros struggle to diagnose without testing.
