Florida Pepper Heat Stress: Shade, Water, and Nematode Check

Central Florida June Heat: Peppers Wilting Despite Flowers

Green peppers in full sun, 90°F+ June heat, severe wilting with flowers and small fruit—heat stress compounded by possible root issues.

Immediate Heat Relief

1. 50% shade cloth: 11 AM - 5 PM daily until temps <90°F
2. Consistent moisture: Deep soak 2×/week, mulch 3 inches straw
3. Mist midday: Reduces leaf temperature 5-10°F

Root Health Investigation

If wilting persists with shade + water:

• Dig one plant—check roots for galls (nematodes) or rot (brown/black)
• FL sandy soil = high nematode risk
• Submit sample to UF/IFAS extension

Nematode Management if Confirmed

• Solarize bed after harvest
• Next season: grafted peppers or 15-gal containers
• Mustard biofumigant rotation

Variety Note

'California Wonder' and similar bells struggle in FL summer heat. Heat-set types: 'Heatwave', 'Solar Set', 'Florida VR2'. Plant Feb-Mar for spring crop; Aug-Sept for fall.

Shade + water + root check. Most June pepper wilt in FL is heat, not disease.
