In the world of gardening, companion planting is a strategy that involves cultivating certain plants near each other to benefit growth and repel pests. When it comes to garlic, selecting the right companions can enhance its flavor, deter pests, and maximize space utilization. Let's explore some of the best companion plants to grow alongside garlic, creating a harmonious and thriving garden ecosystem. Whether you're a seasoned gardener or just starting out, incorporating these companion plants can elevate your garlic cultivation experience to new heights of success and sustainability.

Garlic in the Garden

Garlic, a beloved culinary and medicinal herb, boasts a remarkable resilience against many pests and diseases, making it an ideal addition to any garden. It repels aphids, spider mites, and other common garden pests. However, it is unfortunately susceptible to nematodes and diseases like white rot and rust.

Interestingly, its sulfur compounds act as natural fungicides, offering protection against fungal infections. With its rich history and versatile uses, garlic not only enhances the flavor of dishes but also serves as a natural deterrent to pests, contributing to a healthier and more vibrant garden ecosystem.

Plants That Benefit from Garlic Companions

As garlic deters aphids, it is a fantastic crop to plant next to varieties that suffer from aphid attacks! This may include:

  • Tomatoes,

  • Peppers,

  • Kale,

  • Cabbage,

  • Spinach,

  • Lettuce.

Garlic has strong sulfur compounds and is a natural antifungal too. So, root vegetables that are prone to rot also benefit greatly from a few garlic cloves planted alongside them. This includes:

  • Carrots,

  • Parsnips,

  • Potatoes,

  • Beetroot.

What Helps Garlic Grow?

If it’s your garlic that suffers from pests in your garden, then it can be tough to find companion plants. You don’t want to plant any deep-rooted varieties too close to your garlic, as the garlic bulbs need plenty of space and undisturbed soil to grow large and healthy.

That being said, popular plants to promote garlic health include nasturtiums and marigolds, which are known to repel a whole host of common garden pests. You might also consider planting dill with garlic, as the garlic repels aphids from the herb while the dill is said to enhance the flavor of garlic!

Plants to Move Away from Garlic

While garlic thrives with certain companions, it's best to avoid planting it near beans and legumes like peas, as they can inhibit each other's growth due to their differing nutrient needs. Other alliums, such as onions and shallots, may compete with garlic for resources if planted too closely and provide no protection from spreading diseases like rot.

Parsley and asparagus are also incompatible with garlic, as they can hinder each other's growth and flavor. To optimize garlic's growth and health, it's essential to plan companion planting carefully and avoid incompatible neighbors in the garden bed. If a plant has expansive roots, then garlic won’t be happy to be sharing soil with it!

Using a garden planner or chart is definitely going to make planning companion plants easier too.
