Why Cherry Tomatoes Split and How to Prevent It

The Cause of Splitting

Tomato splitting—especially in cherry varieties—is almost always a response to irregular watering. When a dry spell is followed by heavy rain (or sudden deep watering), the fruit’s interior expands faster than the skin can stretch, causing radial or concentric cracks.

Management in Wet Climates

Since you can’t control rainfall, focus on improving soil drainage and buffering moisture swings:

• Use raised beds (10+ inches deep) filled with a well-draining mix of compost, peat moss, shredded leaves, and aged manure.
• Mulch heavily with straw or dried grass clippings to slow evaporation and moderate soil moisture.
• Water deeply but infrequently—aim for 1–2 inches per week, delivered in one or two sessions, so roots stay in the subsoil rather than rising to the surface.

Can You Eat Split Tomatoes?

Yes, if harvested promptly before mold or insects enter the cracks. Simply cut away the cracked portion.
