Have you ever gone out to your garden to pick a juicy, red tomato, only to find it split open? It can be disappointing, especially after all your hard work. Tomato splitting is a common issue that many of us face, but don’t worry! By understanding why it happens and how to prevent it, you can keep your tomatoes whole and healthy.
What Does Tomato Splitting Look Like?
When a tomato splits, it means the skin just couldn’t keep up. Here’s how it usually goes down:
- Radial Cracks: These look like lines stretching out from the stem, kind of like spokes on a bike wheel.
- Concentric Cracks: These form rings around the stem, like a target.

Both types can make tomatoes look less appealing,and worse, they can invite pests or mold if left on the vine.
Why Do Tomatoes Split?
Tomatoes split because of sudden changes in their growth conditions. Here are the main reasons:
Too Much Water, Too Fast
If a thirsty tomato plant suddenly gets a ton of water—from rain or overzealous watering—the fruit tries to grow faster than its skin can stretch. Boom. Split.
Environmental Factors
Super hot days can make the skin less flexible, and quick shifts in temperature or moisture can push it over the edge.
Tomato Variety
Some tomatoes, like heirlooms, have thinner, delicate skins. They’re tasty, but they’re also more likely to crack under pressure. Other varieties are built tougher.
How to Prevent Tomato Splitting
Good news: you can totally avoid most tomato splitting with a little planning. Here’s how:
- Water Consistently: Keep your tomatoes happy with consistent moisture. Set a watering schedule and stick to it, especially during dry spells. Adding mulch around your plants helps the soil hold water longer and prevents sudden drought-to-flood situations.
- Protect from Weather Extremes: On blazing hot days, consider shading your plants to protect them from getting crispy. During heavy rains, make sure the soil has good drainage to avoid waterlogged roots.
- Choose Tougher Varieties: Some tomato varieties are naturally less prone to splitting. Look for ones labeled “crack-resistant”—they’ll save you some headaches.
What Types Of Tomatoes Are Crack-Resistant?
If you’ve struggled with splitting tomatoes in the past, try growing varieties bred to handle tough conditions. These tomatoes have thicker, sturdier skins and are less likely to crack under pressure. Here are a few gardener favorites:
- Celebrity: Known for its disease resistance and sturdy skin, this variety produces medium-sized, flavorful tomatoes.
- Big Beef: A favorite among gardeners, Big Beef tomatoes are not only resistant to cracking but also deliver excellent taste.
- Juliet: A grape tomato variety with thick skin, making it perfect for snacking or salads without the worry of splitting.

What to Do with Split Tomatoes
Don’t let split tomatoes go to waste! Pick them as soon as you see cracks to keep pests and rot away. Most split tomatoes are still perfectly fine to eat—just check that they’re not moldy. Chop them up for sauces, soups, or salsas, or use them for canning. Once blended, no one will even know they had a rough start!

Frequently Asked Questions
How do I stop my tomatoes from splitting?
To prevent splitting, water your tomatoes consistently to keep moisture levels steady. Use mulch to help the soil retain water and avoid sudden dry-to-wet cycles. Also, grow crack-resistant varieties and provide shade during extreme heat to protect the fruit’s skin.
Are tomatoes that split still good to eat?
Split tomatoes are usually safe to eat as long as they’re not moldy or rotten. Inspect the cracks for signs of pests or spoilage and use the tomatoes quickly. They’re perfect for sauces, soups, and canning, where appearance doesn’t matter.
Does overwatering cause tomatoes to split?
Overwatering or sudden heavy rain after a dry spell can cause tomatoes to split. When the plant absorbs too much water too quickly, the fruit grows faster than the skin can stretch.
