Tomatoes are one of the most popular garden crops, loved for their juicy flavor and vibrant color. But if you’ve ever walked into your garden or kitchen and noticed strange holes in your tomatoes, it’s natural to be concerned. These holes may seem like a minor flaw, but they often signal a bigger issue that needs attention.
Here’s what you need to know about what causes holes in tomatoes and how to prevent them.
1. What Causes Holes in Tomatoes?
Most holes in tomatoes are caused by insects or pests. The most common culprits include:
- Tomato Fruitworms (Corn Earworms): These pests chew holes into the fruit, leaving visible entry points. They can burrow deep inside, damaging the inner flesh.
- Tomato Hornworms: These large, green caterpillars not only eat leaves but also dig holes in tomatoes.
- Stink Bugs: These pests pierce the skin of the tomato and suck the juices out, which can leave behind pockmarks or sunken holes.
- Slugs and Snails: Typically active at night, they feed on ripe fruit, leaving irregular holes.
- Birds or Rodents: Small bite-like holes, often with missing chunks of fruit, may be the work of animals seeking moisture.
2. Are Tomatoes with Holes Safe to Eat?
If the hole is small and recent, and there’s no sign of mold or rot, the tomato may still be safe to eat after trimming the damaged area. However, tomatoes that have:
- Deep burrows
- Mushy texture around the hole
- Signs of insects inside
- Mold or sour smell
…should be discarded to avoid potential foodborne illness.
3. How to Prevent Holes in Tomatoes
To protect your tomato plants and ensure a healthy harvest, follow these preventive tips:
- Regular Inspection: Check plants frequently for caterpillars, eggs, and signs of insect damage.
- Handpicking Pests: Remove hornworms or fruitworms manually if seen.
- Use Natural Sprays: Neem oil or insecticidal soap can deter many common pests.
- Mulching and Cleanliness: Keep the area around your plants clean and mulched to reduce hiding spots for pests.
- Netting or Row Covers: These can prevent birds and insects from accessing the fruits.
- Companion Planting: Planting basil, marigold, or garlic nearby can naturally repel harmful insects.
4. When Holes Might Be a Sign of Disease
While pests are the primary cause, disease or environmental factors can also contribute. Cracking, spots, or soft sunken holes may be signs of:
- Blossom-end rot (due to calcium deficiency)
- Fungal infections like anthracnose
- Bacterial speck or spot
In such cases, improving watering practices, using calcium-rich fertilizers, and rotating crops each season can help.
Conclusion
Holes in tomatoes are more than just a cosmetic issue — they can signal pests or disease problems that could spread to the rest of your crop. By staying vigilant and using natural prevention methods, you can enjoy a bountiful harvest of healthy, hole-free tomatoes. And when in doubt, inspect the inside of the fruit carefully before eating — safety always comes first.
