Tomatoes are a garden favorite, loved for their taste and versatility. But a common headache for gardeners is when tomatoes crack or split before they’re ripe. Not only does this make them look less appealing, but it can also open the door to pests and mold (which can cause a real mess later on). Knowing why tomatoes crack and what you can do to stop it is a smart move if you want to enjoy a steady supply of healthy, tasty fruit.
The problem with cracked and split tomatoes
Tomato cracking usually happens when there’s a sudden change in watering. This often means heavy rain followed by a dry spell—or the other way around. Such swings make the tomato’s skin swell too quickly, causing splits. These cracks go beyond just how they look. They can weaken the fruit (making it easier for bugs, mold, and fungus to take hold).
If you’re dealing with unpredictable weather, it’s good to keep an eye on your tomatoes. Notice any early cracks? If they’re still green, try picking them early and let them finish ripening off the vine. If they’re already ripe and have a split here and there, just trim off the damaged part (the rest of the fruit is still good to eat).
Preventing cracks the smart way
The key to stopping tomato cracking is keeping your watering as regular as possible. A steady watering routine helps maintain even moisture in the soil, which keeps the tomato skin from suddenly bursting. For those planting tomatoes in greenhouses, managing moisture is even easier since you’re working in a controlled setting.
Setting up your own mini-greenhouse doesn’t have to break the bank. You can rig up a simple one using a shade tent or some household items (this makes it easier to keep those conditions consistent for your plants).
Watering routine for your tomatoes
When it comes to watering tomatoes, consistency really matters. A general rule is about one inch per week, maybe a bit more if the weather is extra hot. Avoid giving your plants water on and off since that can cause them to split.
A handy trick is the “finger test”—just stick your finger about an inch into the soil. If it feels dry, it’s time for a drink for your plants. And during those blazing summer months, keep a closer watch because the soil dries out much faster.
The best way to water
How you water matters just as much as when you water. Aim to get water directly into the soil rather than onto the leaves, vines, or fruit (this helps keep diseases at bay). Using a hose or a watering can with a narrow neck targets the roots directly, where your tomatoes need it most.
Skip the sprinklers if you can—they tend to wet the whole plant, wasting water and raising humidity around the foliage (this extra dampness can encourage fungal issues).
By sticking to a regular watering schedule and using the right techniques, you can keep your tomatoes from cracking and help them stay in tip-top shape throughout the growing season. Paying attention to these steps means you’ll be better prepared to dodge common pitfalls and enjoy a steady harvest of vibrant, tasty tomatoes year after year.
