Smart Herb Companion Planting for Gardeners


Herbs are a great addition to any garden, but did you know that they can also be used as companion plants in your vegetable garden? Companion planting is an ancient practice that involves placing certain species together in proximity to one another for the purpose of mutual benefit. Smart herb companion planting may help repel certain pests like aphids and cabbage moths, attract other beneficial insects such as ladybugs, attract pollinators, and promote healthy overall growth for all.

This article will tell you everything you need to know about herb companion planting from what it is, the benefits of doing so, and a handy herb companion planting chart that outlines great herb/vegetable combinations to try out in your own herb garden!

What exactly are herbs?

Since we’re on the subject of herbs, we should define what exactly a herb is.

According to Cambridge Dictionary a herb is, “a type of plant with a soft stem, used in cooking and medicine.” The keyword here is “soft” stem rather than woody stems often used in spices.

More specifically with herbs, the leaves of these plants and occasionally the flowers, are generally used fresh or dried for their flavor or fragrance.

Herbs differ from spices in that typically spices come from other parts of the plant including the buds, bark, flowers, root, seeds, and stems. Spices are dried.

Everyone has a few favorite culinary herbs they use regularly to bring out the flavors of homemade dishes. But herbs are useful in so many ways beyond just culinary purposes.

  • Culinary herbs: Add new flavor profiles and dimension to all your culinary creations. A few examples of culinary herbs are: bay leaf, basil, chives, mint, parsley, rosemary, sage, and tarragon.
  • Decorative or ornamental herbs: Some herbs are simply lovely to behold with pretty foliage and flowers, and are useful for filling in sparse areas in the garden, accentuating other plants, and providing a border. A few examples of ornamental herbs include: bergamot, catmint, lovage, ornamental oregano (pinkish flowers), rose, rosemary, silver thyme, and tansy.
  • Scented herbs: While it could be said that virtually all herbs have a unique scent, some really stand out in this category. Examples of herbs coveted for their aroma include: basil, chamomile, scented geranium, lavender, lemon balm, marigold, mint, patchouli, rose, rue, and thyme.
  • Medicinal herbs: Some herbs are used for their healing, soothing, or anti-inflammatory properties. A few examples include: anise, horehound, hyssop, and feverfew.

Benefits of herb companion planting

Companion planting has long been used as a natural method of enhancing plant growth and deterring pests. It’s a great way to make the most of the herbs in the garden (and hopefully make your job easier too!).

When planted next to one another, some herbs just jive well with their neighbors, bringing about a mutually beneficial relationship. A “you scratch my back, I’ll scratch yours” kind of thing.

Each relationship between herbs and surrounding plants is unique. You may find that by planting certain herbs next to certain crops, you might just reap the rewards of one or more of the following benefits of herb companion planting:

  • Repels pests: Common garden pests are aphids, cabbage maggots, slugs, and snails. Some herbs such as pennyroyal and pyrethrum are good insect repellents.
  • Attracts helpful insects: As you know, certain insects such as ladybugs are a gardener’s friend by helping to get of other pests. Parsley for example, attracts ladybugs and damselflies which help neighboring carrots, chives, and tomatoes.
  • Enhances growth and overall health: Some herbs help out by providing soil enrichment, shade, and water retention.
  • Improves herb aroma and flavor: Lemon verbena and lemon thyme complement one another’s fragrances. Keep in mind that some strongly scented herbs may affect the scents of other nearby herbs and plants—you may wish to group similarly-scented herbs together.
  • May suppress weed growth: Some low-growing herbs such as marjoram or thyme may be planted amongst other crops to prevent sun-loving weeds from sprouting.

Tip: Are you ready to plan out your garden? As a general rule, it’s best to match the soil, water, and light requirements of companion herbs to ensure you’re not planting a water-loving herb next to one that prefers well-drained soil.

The classic Three Sisters companion planting trio

One of the best examples of great companion planting is what’s known as the Three Sisters combo used for ages by North American Indigenous people: beans, corn, and squash.

It’s a great example of how ideal companion planting works—three crops working together in harmony.

  • Beans make nitrogen available in the soil to the benefit of others;
  • Corn provides the necessary support for bean’s twisting vines;
  • Squash’s low-growing foliage provides ground cover which helps to retain soil moisture. The prickly stems help deter pests and protect the other “sisters;”
  • And, there’s sometimes a fourth sister—sunflower or beebalm which acts to provide further support to the beans, while also deterring birds from snacking on the corn by offering up her own seeds, and attracting bees and other pollinators.
