What Flowers Keep Bugs Away from Tomato Plants

Tomatoes are a popular and nutritious fruit that are enjoyed by many people around the world. However, they are also quite vulnerable to insects and other pests. While there are many pesticides and other chemical treatments available to protect tomato plants from bugs, many people prefer a more natural approach. One effective method of deterring pests from tomato plants is the use of companion planting. Companion planting involves growing certain plants alongside others to provide a range of benefits, including pest control. In this article, we will explore some of the best flowers to plant alongside tomatoes to keep bugs away.

1. Marigold

Marigolds are a popular choice for companion planting because they are easy to grow and can tolerate a variety of growing conditions. They are also highly effective at deterring various insects, including nematodes, whiteflies, and tomato hornworms. Marigolds contain a natural compound called alpha-terthienyl, which is toxic to many insects. Planting marigolds around the perimeter of your tomato patch can help create a barrier that keeps these pests at bay. To get the most benefit from marigolds, it is best to plant them in a range of colors and varieties.

2. Petunia

Petunias are another popular choice for companion planting with tomatoes. They are easy to grow and produce beautiful, colorful flowers that add visual interest to your garden. Beyond their aesthetic value, petunias are also highly effective at deterring certain insects, such as aphids and tomato hornworms. These flowers contain a natural compound called solasodine, which is toxic to many pests. Planting petunias near your tomato plants can help repel these insects and keep your tomatoes healthy.

3. Nasturtium

Nasturtiums are a versatile flower that can be grown in a variety of conditions, including in pots or containers. They are prized for their attractive flowers, which come in a range of colors and varieties. Beyond their ornamental value, nasturtiums are also highly effective at deterring certain insects, such as aphids, whiteflies, and squash bugs. These flowers contain a natural compound called linalool, which is toxic to many pests. Planting nasturtiums in and around your tomato patch can help deter these bugs and protect your plants.

4. Borage

Borage is an herb that is often overlooked as a companion plant for tomatoes. However, it is highly effective at detering certain insects, such as tomato hornworms, cabbage worms, and squash bugs. Borage contains a natural compound called pyrrolizidine alkaloids, which is toxic to many pests. Planting borage near your tomato plants can help repel these insects and keep your plants healthy. Additionally, borage is an edible herb that can be used in a variety of culinary applications.

5. Chrysanthemum

Chrysanthemums are a popular choice for companion planting because they are highly effective at deterring a wide range of insects, including aphids, spider mites, and whiteflies. These flowers contain a natural compound called pyrethrin, which is toxic to many pests. Planting chrysanthemums in and around your tomato patch can help keep these pests at bay and ensure your plants are healthy and productive.

In conclusion, companion planting with flowers is an effective and natural way to deter insects and other pests from your tomato plants. By adding marigolds, petunias, nasturtiums, borage, and chrysanthemums to your garden, you can create a beautiful and healthy environment for your tomatoes to thrive in. With a little bit of planning and care, you can enjoy a bountiful harvest of delicious, insect-free tomatoes.
