Hibiscus Leaf Yellowing in Florida Autumn: Seasonal Stress

Normal Response to Cooler, Drier Weather

Hibiscus in ground shed leaves and yellow when nights cool and rain decreases. It's a temporary adjustment, not a disease.

Management

• Reduce irrigation: twice-weekly light sprinkler is too much now.
• Scout for aphids/scale on buds and new growth.
• Do not fertilize until spring growth resumes.

Recovery

Plants stabilize and reflush when warm, humid weather returns.
