What Flowers Help Keep Hornworms from Tomato Plants

Hornworms are a common and destructive pest for tomato plants. These large, green caterpillars can quickly defoliate and destroy the foliage of a tomato plant, leaving it weak and vulnerable to disease. Fortunately, there are a variety of flowers that can help keep hornworms away from your tomato plants. Here are some of the best options:

1. Marigolds

Marigolds are a popular choice for companion planting with tomatoes, and for good reason. Not only do they add a cheerful pop of color to your garden, but they also have a strong scent that repels many pests, including hornworms. Plant marigolds around the perimeter of your tomato patch or interplant them with your tomatoes to help keep these pests at bay.

2. Petunias

Petunias are another flowering plant that can help repel hornworms. Like marigolds, they have a strong scent that pests find unpleasant. Plant petunias in pots or around the base of your tomato plants to create a barrier that will keep hornworms away from your precious tomatoes.

3. Nasturtiums

Nasturtiums are a colorful and edible flower that can also be used to deter pests. Their peppery scent and taste repels hornworms, as well as other pests like aphids and cabbage worms. Nasturtiums can be grown in the same bed as your tomato plants, or in pots around the perimeter of your garden.

4. Borage

Borage is a herb that produces beautiful, star-shaped blue flowers. In addition to being a pretty addition to your garden, borage also has several benefits for your tomato plants. It attracts beneficial insects like bees and predatory wasps, which can help control hornworm populations. Borage also has a unique scent that repels hornworms and other pests.

5. Dill

Dill is a herb that is often grown for its flavorful leaves and seeds. However, it also has insect-repelling properties that make it a great choice for companion planting with tomatoes. Dill attracts beneficial insects, like ladybugs and lacewings, that can feed on hornworm eggs and larvae. Plant dill near your tomato plants to help keep hornworms at bay.

By incorporating these flowering plants into your tomato patch, you can help protect your plants from destructive hornworms. These plants not only add beauty and diversity to your garden, but they also provide natural pest control that can help you grow healthy and productive tomato plants.
