Garlic (Allium sativum) is a remarkable plant that offers numerous benefits to its neighboring plants. Not only does it deter pests, but it also provides sulfur, a natural fungicide. As a result, garlic is widely used as a companion plant in gardens.
In this article, we will explore the best and worst companion plants for garlic, providing you with valuable insights to maximize the health and productivity of your garden.
Understanding Companion Planting
Companion planting is a time-honored practice in which species are strategically placed near each other to harness mutual benefits that promote optimal growth. By capitalizing on nature’s synergies, gardeners can create a harmonious ecosystem that deters pests, improves soil fertility, and enhances crop yields.
We gardeners often employ companion planting as an alternative to heavy chemical pesticide use. By harnessing the power of natural plant interactions, you can safeguard your crops while nurturing a thriving and sustainable garden.
The Benefits of Garlic as a Companion Plant
Garlic possesses a wide range of benefits that make it an excellent companion plant for various species. Its pungent aroma and potent compounds act as natural deterrents against many common pests, including aphids, spider mites, fungus gnats, Japanese beetles, snails, and cabbage loopers.

The adaptability of garlic is another advantage, as it can thrive in various soil types and environmental conditions as long as there is ample sunlight.
