Companion planting is a great way to maximize the efficiency of your garden. For almost every vegetable you grow, there is likely to be a beneficial companion plant that will help increase soil nutrients, chase away pests, and help you get the most out of your garden.
Basil and tomatoes were made to go together, not only in sauces but in the garden, too. This herb helps tomatoes produce greater yields and it repels both flies and mosquitoes. Marigolds are another good companion, repelling nematodes and other garden pests. Other friends of tomatoes include asparagus, carrots, celery, the onion family, lettuce, parsley, and spinach.
Corn and beans grow well together because beans will grow up the cornstalks, which means you won’t have to build them a trellis. Beans also fix nitrogen in the soil, which is good for the corn. Marigolds, nasturtiums, rosemary, and summer savory repel bean beetles, and summer savory improves growth rate and flavor. Other companions include broccoli, Brussels sprouts, and other members of the cabbage family along with cucumbers, peas, potatoes, and radishes.
Carrots should be planted near onions because onions will repel the carrot fly. Onions will also chase away the aphids, so plant them near aphid-prone (but onion-friendly) veggies. Other good friends of onions include beets, cabbage, carrots, lettuce, parsnips (which also suffer from carrot fly), tomatoes, and spices like marjoram, savory, and rosemary.
Plant mint among your lettuce to keep away the slugs that feed on lettuce leaves, or plant chives and garlic to repel aphids. Beans, beets, broccoli, carrots, corn, peas, radishes, and marigolds also work as good companion plants. Marigolds attract aphid-eating ladybugs.
Follow these companion planting guidelines to boost yields, minimize pest or disease problems and make garden management easier!
