Why Cherry Tomatoes Are Splitting (The Real Cause)
So, why are cherry tomatoes splitting and why are cherry tomatoes are splitting even when they looked fine yesterday? It usually comes down to fluctuations in soil moisture.
When soil dries out, the skins tighten. Then a big watering or heavy rain hits, and the plant pulls in water fast. The inside of the tomato fruits expands, and you get tomatoes cracking.
That’s why you may see cherry tomatoes split on vine or notice cherry tomatoes splitting on the vine in clusters. If you’ve searched why are my cherry tomatoes splitting on the vine, the answer is almost always uneven watering or sudden rain.
This is also why why do cherry tomatoes split on the vine is such a common question during hot weather.
Types of Cracks: What You’re Seeing
There are a few types of cracks, and they tell you what happened:
- Vertical split (one long crack running down the fruit)
- Circular cracks near the top
Gardeners often describe these as patterns radial cracking and concentric cracking. Both can happen when moisture changes too quickly, and some fruit is simply more prone to splitting depending on your weather and tomato varieties.

How to Prevent Cherry Tomatoes From Splitting
To prevent tomatoes from splitting, focus on steady moisture. Your goal is consistent soil moisture levels, not a cycle of dry soil followed by flooding.
What helps prevent splitting
Water consistently
Cherry tomatoes do best when watered on a regular schedule. Deep, even watering helps the plant take up moisture slowly. In hot weather, plants may need water every day, especially in containers. Skipping water for several days and then watering heavily is a common cause of splitting.
Use mulch to protect soil moisture
Mulch acts like a blanket over the soil. It slows evaporation, keeps roots cooler, and helps maintain even moisture. Straw, shredded leaves, or compost all work well. Mulched plants are far less likely to split fruit after a hot day or sudden rain.
Adjust watering after rain
After a heavy rain, the soil may already be holding plenty of water. If you continue watering right away, the fruit can take in too much moisture. Wait until the top inch of soil feels slightly dry before watering again.
Harvest on time
Ripe cherry tomatoes split more easily than firm, slightly under-ripe fruit. If tomatoes are fully colored and feel soft, pick them. Leaving ripe fruit on the vine increases the risk of cracking, especially if rain or heavy watering follows.
Choose steady-growing varieties
Some cherry tomato varieties have slightly thicker skins and better resistance to splitting. While no tomato is completely crack-proof, strong, healthy plants handle moisture changes better than stressed plants.
Conclusion
So if you’re stuck on why cherry tomatoes split, remember this: it’s usually water stress, not a mystery disease. Keep moisture steady, harvest smart, and you’ll see fewer cracked fruits and more perfect cherry tomatoes.
