14 Plants That Should Never Be Grown Together In The Garden

We already showed you which plants should be grown together (read more – 14 Plants That Should Always Be Grown Together In The Garden Part I & Part II), but do you know which plants should never be grown together in the garden?

Peppers and Beans

Peppers and beans are both helpless to anthracnose, so if one of them gets it, they’ll both end up contaminated. This sickness ruins the fruits by causing dark, soft spots to show up.

Black Walnuts and Tomatoes

Black walnut trees are famous for being awful neighbors. The trees’ root system transmit a compound called juglone, which is dangerous to some deep-rooted plants planted around it, for example, tomatoes. If you have walnut trees in your garden, you might want to plant the tomatoes in a container or raised beds.

Onions and Peas

Actually, you should never plant any of the members from the onion family (shallots, garlic…)with peas. The onions can stunt the development of peas and beans.

Carrots and Dill

The fact that dill and carrots are enemies has no scientific evidence, however many gardeners have come to this conclusion by their years of experience.

Potatoes and Tomatoes

They’re attacked by the same blights, so when they’re grown together, the diseases will spread all the more effectively.

Cabbage and Grapes

Sowing cabbage close to grape vines will ruin your homemade wine. Gardeners saw this antagonistic impact some 2,000 years ago.

Lettuce and Broccoli

A research has shown that lettuce is sensitive to chemicals found in deposits left behind by broccoli plants. Sowing lettuce close to broccoli (or even in the spot where they used to grow) may block seed germination and development.
