The Best Companion Plants: What to Grow Together
Use plant partnerships to naturally deter pests, improve soil health, and create a more beautiful garden.
Nature Does Not Grow in Rows
Modern gardening often mimics a grocery store shelf, with long, isolated rows of a single plant. Nature, however, grows in messy, cooperative tangles. Companion planting is the practice of mimicking these natural relationships. By placing certain plants next to each other, you can confuse pests, attract beneficial predators, and even improve the flavor of your harvest. It is about creating a tiny, functional ecosystem where every member helps the others. If you are tired of spraying chemicals to save your garden, it is time to start thinking about who your plants' best friends are.
The Classic Pairings
One of the most reliable companions is the Marigold. These flowers produce a scent that confuses many garden pests and their roots release a compound that repels nematodes. Plant them as a border around vegetable beds or tuck them between ornamentals. For Rose bushes, interplanting with Chives or garlic can help deter aphids and may even prevent black spot fungus. The strong allium scent masks the rose's sweetness from pests. If you have the space, the "Three Sisters" method from Indigenous agriculture pairs corn, beans, and squash. The corn provides a trellis for the beans, the beans fix nitrogen in the soil, and the large squash leaves act as a living mulch.
Beauty with Benefits
Borage is an essential companion. Its bright blue flowers attract pollinators like crazy, which is vital for getting a good yield from any fruit-bearing plants nearby. Nasturtiums act as a "trap crop," meaning aphids prefer them over your other plants. They will swarm the nasturtium, leaving your prized specimens alone. In the perennial border, think about bloom-time partnerships. Pair early spring bulbs with late-emerging perennials so the dying bulb foliage is hidden by fresh growth. Mix tall, airy plants like meadow rue with dense, mounding ones like catmint. By thinking in partnerships instead of individual specimens, you create a garden that is both more resilient and more visually interesting.
