Azalea Leaf Drop in Winter: Normal or Problem?

Semi-Evergreen Behavior

Some Oriental azaleas (like 'George L. Taber') are semi-evergreen. Depending on temperature, they may drop up to ¾ of their leaves in winter. Spring-produced leaves (lower on branches) drop most; summer leaves persist.

When to Worry

• Normal: Green tips with only lower leaves yellowing and dropping.
• Problem: ALL leaves yellow and dropping—suspect poor drainage and root rot.
