No one likes to see precious garden vegetables eaten away by bugs. What if you could keep those damaging insects away from your edibles without using insecticides? All it takes is a few helpful plants, better known as companion plants.
Companion plants help keep unwanted bugs away, but they also attract pollinators for many vegetables, like cucumbers, melons, squash and tomatoes. You may be surprised to discover that you are probably already familiar with many of these helpful plants.

How Companion Plants WorkThere are many companion plants that help repel damaging insects. You may wonder, how do they do that?
Insects are often guided to plants by their scent. Aromatic plants such as
marigolds, garlic,
nasturtiums and
basil will help keep bad bugs away from your vegetable garden.

Other ways that companion plants help in the vegetable garden is by attracting beneficial insects, which help pollinate flowering vegetables. Some companion plants also attract good bugs that will eat the unwanted bugs.

Companion plants work best when planted alongside vegetables. You can plant them between rows of vegetables, or you can simply intersperse them throughout the growing vegetables. Most companion plants are easily grown from seed and can be planted at the same time as your vegetable seeds.

Basil masks the alluring scent of your vegetable plants, keeping bad bugs away. Here are two other reasons to grow basil in your garden:
- Basil is very easy to grow from seed or seedlings once the danger of frost has passed. You can also grow it in containers.

Nasturtiums are great companion plants because bugs hate their peppery scent. They not only repel bugs you don’t want around, they also
attract pollinators. But there are other benefits of adding nasturtiums to your vegetable garden:
• Every part of nasturtiums is edible, and they add a delicious, peppery taste to salads.
• They are easy to grow from seed.
• The flowers add beauty to any vegetable garden.
