Why Are My Tomatoes Splitting? Water and Heat Management

Causes of Fruit Cracking

Splitting (concentric or radial) occurs when fruit expands faster than skin due to:

Consistent moisture: 2 inches/week, evenly applied.
Mulch heavily (3–4" straw) to buffer soil moisture.
Drip irrigation avoids wet/dry cycles.
Harvest at breaker stage (first pink blush)—ripens indoors without splitting.
Choose crack-resistant varieties: 'Celebrity', 'Mountain Fresh', 'Jet Star'.

Water deeply in evening during heat waves to reduce evaporation and nighttime stress. Avoid wetting foliage.
