14 Plants That Are Not good Neighbors

This is all about companion planting which is the technique of growing certain crops side by side either because they help promote growth or deter pests. On the other hand there various combinations of plants that should be avoided since they have a detrimental effect. This article by Rebecca Straus which I found on the Rodale’s Organic Life website describes fourteen plants that should never be grown next to each other.

Companion planting is the practice of growing crops that are natural allies side-by-side. It?s a tradition based on many years of observations by dedicated gardeners, though in a few cases science backs up the practice, too. The most famous example of companion planting is the ?Three Sisters? that Native American farmers planted together?squash, corn, and beans. The three vegetables grow together perfectly: The corn acts as a trellis for the beans, the beans return nutrients to the soil, and the broad leaves of the squash literally ?squash? down weeds while locking moisture into the soil, explains The University of California Master Gardeners. But what about plants that are natural enemies in the vegetable garden? Here are seven combinations companion planters say are no-gos.
Onions + Peas

Onions + Peas
Traditional wisdom says you should never plant members of the onion family?including shallots and garlic?with peas. According to the Farmer?s Almanac, companion planters believe the onions can stunt peas? (and beans?) growth.
potatoes and tomatoes

Potatoes + Tomatoes
According to The University of California Master Gardeners, growing tomatoes and potatoes together spells trouble. They?re attacked by the same blights, so when they?re right next to each other, the diseases spread more easily.
peppers and beans

Peppers + Beans
According to Rodale?s Successful Organic Gardening: Companion Planting, peppers and beans are both susceptible to anthracnose, so if one gets it, they?ll both wind up infected when planted side-by-side. This disease ruins fruits by causing dark, soft spots to appear.
