How to Keep Horn Worms off Tomato Plants Organically

Horn worms are among the most common pests that attack tomato plants. They are large green caterpillars with horn-like protuberances on their head that can quickly destroy your plants if not managed properly. While there are many chemical solutions available in the market to control these pests, organic methods are safer and more environmentally friendly. In this article, we will discuss some effective ways to keep horn worms off tomato plants using organic methods.

1. Handpicking

One of the most effective and organic ways to control horn worms is to handpick them. Look for these pests in the early morning or late evening hours as they are more active during these times. To identify these caterpillars, look for the white stripes on their body and the horn-like projections on their head. Once you locate them, carefully pluck them off the plant and drop them in a bucket of soapy water to kill them.

2. Attract Beneficial Insects

Another great way to keep horn worms off tomato plants organically is to attract beneficial insects, such as parasitic wasps, ladybugs, and lacewings. These insects prey on horn worms and other pests that attack tomato plants. To attract these insects to your garden, plant flowers like marigolds, cosmos, and zinnias, which are known to attract beneficial insects. You can also make your own insecticide spray using garlic, hot peppers, and dish soap to keep these insects happy in your garden.

3. Companion Planting

Companion planting is another great way to keep horn worms off tomato plants organically. Plants like basil, borage, and dill are known to repel horn worms and attract beneficial insects. Plant these herbs around your tomato plants to protect them from pests. Similarly, plants like marigolds, nasturtiums, and petunias give off a scent that repels many pests, including horn worms. Plant these flowers as a border around your tomato plants to keep pests at bay.

4. Crop Rotation

Crop rotation is an effective way to prevent pests, including horn worms, from attacking your tomato plants. Horn worms can stay in the soil and continue to feed on roots even after tomato plants have been removed. To prevent this, rotate your crops every year, and try not to plant tomatoes in the same spot for at least two years. This will help to break the life cycle of the horn worms and prevent them from attacking your tomato plants.

5. Neem Oil

Neem oil is a natural insecticide that is extracted from the neem tree. It is effective in controlling a wide range of pests, including horn worms. To use neem oil as a pesticide, mix two tablespoons of pure neem oil with a gallon of water and a few drops of dish soap. Spray this solution on your tomato plants, ensuring that you cover the undersides of the leaves as well. Repeat this process once a week to control horn worms and other pests.

Conclusion

Tomato plants are susceptible to many pests, including horn worms that can quickly destroy your harvest. While chemical pesticides are available, organic methods are safer and more environmentally friendly. Handpicking, attracting beneficial insects, companion planting, crop rotation, and neem oil are all effective ways to keep horn worms off your tomato plants without harming the environment or your health.
