Plants That Don't Grow Well Together

Companion planting is a gardening technique that involves planting complementary plants together to help produce a beneficial outcome - ranging from improved health to enhanced taste. Common companion planting pairings include tomatoes and basil - which helps improve the flavor of tomatoes - and marigolds around vegetable gardens to help ward off pests.

In addition to improving your at-home menu with fresh produce, companion planting also can help create rich soil and crowd out weeds. However, even though there are many benefits to companion planting, not all plants make good neighbors.

Before you reach for the tiller and planting trowel this season, be sure to review this companion planting guide so you can get the most from your garden.

Tomatoes + Carrots, Cucumbers or Corn

While tomatoes can grow well in a variety of weather conditions, they can be temperamental when it comes to companion planting. Sharing a pot or plot with other vegetables like carrots, corn and cucumbers can deplete your tomatoes' flavor and color. When pairing tomatoes, stick to leafy plants like lettuce, basil and spinach. Growing these plants together allows an even distribution of nutrients throughout the garden and even enhances the overall taste of the tomatoes.

Peppers + Cabbage or Greens

Available in a wide variety, bell peppers can protect onions and tomatoes from pests like beetles and nematodes, can can also improve flavor when paired with basil and carrots. However, peppers can struggle in the garden if grown in the same environment as cabbage or greens, since they are nutrient-hungry vegetables.

Beans + Onions, Garlic or Chives

Beans are known to release essential nitrogen back into the soil as they grown. This nutrient can benefit the growth of nearby plants and reduce the need for fertilizer. However, it's best to avoid planting beans alongside onions, garlic and chives, as these plants can hinder the growth of beans.
