Sun Scald on Hibiscus Leaves: Overhead Watering in Intense Florida Sun

Symptoms of Water-Induced Leaf Bleaching

White patches that disappear overnight indicate sun scald—water droplets act as lenses, burning tissue.

Correct Watering Technique for Tropical Shrubs

Water at soil level, not overhead. Deep soak once a week unless extreme heat/drought.

Fertilizer Timing and Frequency

Fertilize after watering. Your schedule (every couple months) is fine.

Monitoring for True Disease

If white areas persist or spread, suspect fungal disease. Consult extension.
