7 Plant Pairs You Should Always Grow Next to Each Other

These plant pairs grow better together.

When it comes to gardening, a little planning can go a long way. Planning can save time, hassle, and your precious plants in the process. This is especially true of companion gardening, which refers to the pairing of plants that have properties that benefit each other.

"It may be that one plant attracts pollinators or deters insects, while another enhances nutrient intake. Whether you have a large plot or a small raised bed, combining certain fruits, vegetables, flowers, and herbs will improve your garden's biodiversity," explains George Pisegna, the deputy director and chief of horticulture at the Horticultural Society of New York.

From tomatoes and basil to eggplant and spinach, see below for experts' favorite companion gardening combinations, what to do with them, and a few gardening tricks.

Brassicas and Calendula

Why it works: "Pests, such as aphids, are very attracted to the pollen and nectar of the calendula, leaving the brassicas (broccoli, cauliflower, collard greens) food crops alone to thrive," says Pisegna.

Melons and Herbs

Why it works: "By allowing your herbs to flower, you will attract more pollinators to the melons, which will help them prosper and taste sweeter," says Pisegna. Once they've bloomed, learn how to increase the shelf life of your fresh herbs with our foolproof tips.

Potatoes and Marigold

Why it works: "The strong scent of the marigold contains substances that repel the potato beetle, which can cause a lot of damage to the potato plant," says Pisegna. If you're in the mood for comfort food, you can't go wrong with these melting potatoes.

Carrots and Radishes

Why it works: This pairing is more about making the most of your garden space than anything else. "Radishes grow in the upper level of the soil, while carrot roots grow deeper. Each plant pulls nutrients from a different area in the soil," explains Pisegna.

Eggplant and Spinach

Why it works: "The eggplant will grow tall, providing some shade for the spinach. Further, the dense growth of the spinach will help suppress weeds," notes Pisegna. Find out why eggplant is one of the garden's best multi-taskers.

Cucumbers and Nasturtiums

Why it works: The trick here is to plant nasturtiums at the base of a trellis for cucumbers. "The peppery scent of the nasturtium flower will help repel the cucumber beetle," suggests Pisegna. "Otherwise, the beetle can eat new leaf growth that can stunt the plant, along with flowers that will decrease production."
