How to Keep Insects from Eating Tomato Plants

Tomatoes are popular among gardeners and home growers because of their versatility in the kitchen and the rewards of a harvest. However, they are also a favorite of insects that can damage the plant or even kill it. Luckily, there are several easy and organic ways to keep insects from eating your tomato plants.

Choose Resistant Varieties

The first step in keeping insects away from your tomato plants is to select resistant varieties. Many breeders have developed tomato plants that are resistant to some of the most common pests, such as tomato hornworms, aphids, and whiteflies. When shopping for tomato plants or seeds, look for “disease-resistant” or “pest-resistant” labels.

Keep Your Garden Clean

One of the essential ways to prevent insects from attacking your tomato plants is to keep your garden clean. Remove any dead leaves or plant debris from around the plants. The debris can harbor pests and diseases that can be transferred to your plants. Also, regularly weed your garden to prevent insects from using weeds as a host for their eggs.

Use Organic Pesticides and Insecticides

If you notice any insect infestations on your tomato plants, there are several organic pesticides and insecticides you can use to control them. Bacillus thuringiensis (BT) is a safe and effective bacterium that kills tomato hornworms and other caterpillars without harming beneficial insects. Neem oil is another organic insecticide that targets aphids, spider mites, and whiteflies.

Attract Beneficial Insects

Another effective and natural way to keep insects from eating tomato plants is to attract beneficial insects to your garden. Ladybugs, lacewings, and praying mantises are excellent natural predators of insect pests. You can attract them to your garden by planting flowers that they like, such as marigolds or zinnias. Also, create a water source for them like a bird bath or put out shallow dishes of water.

Use Companion Planting

Planting herbs and vegetables that have insect-repelling properties around your tomato plants can also help protect them. Some good companion plants for tomatoes are basil, garlic, and marigolds. The strong scent of these plants repels insects, making them less likely to attack your tomato plants.

Conclusion

Tomato plants are a favorite of insects, and they can quickly infest and damage your plants. However, using organic pesticides, attracting beneficial insects, and planting companion plants can keep these pests at bay. Remember to keep your garden clean and select resistant tomato varieties to keep your plants thriving and healthy.
