To grow garlic, you need fertile well-drained soil, plenty of moisture, lots of sun and a good winter (cold, but not too soggy) to spur the bulbs into action. If you have these things sorted, great!

By getting good at growing garlic, you could be helping lots of other vegetables too. This is because garlic makes an ideal companion for many other plants. We’ll talk more about the best garlic companion plants below.

What are companion plants?

Companion planting is when you grow plants next to each other that benefit one another. Usually, this is done for three reasons – to improve the soil, to attract pollinators, and to keep pests off.

You may have heard about companion plants a lot more lately, with the growing interest in organic gardening. It’s not a new way of growing; organic fans have been doing it for years. Companion planting works, and it often means you don’t need to get chemicals involved to deal with pests.

With garlic, it’s usually the pest-repelling properties that make it an ideal neighbor for many other plants

How does garlic help other plants?

You know how pungent garlic is? Well, it turns out this is one of its most valued attributes when it comes to garden pests.

Aphids hate the smell of garlic and will not go near it. This goes for many other insects that might want to snack on your veggies too: spider mites, gnats, beetles, snails and caterpillars. As well as deterring insect pests, garlic is known to put off other nibblers including rodents.

The garlic cloves release sulphur into the soil around them; this is absorbed by the rose. Aphids, snails, caterpillars and other bugs will all be put off visiting.
