If you’re wondering which plants go well with peppermint, keep reading! Because below, I talk about the benefits of companion planting before walking you through what to look for when finding companion plants for peppermint as well as what plants make great companions for peppermint and which should be avoided.

What Is Companion Planting?

Companion planting is a great way to get your garden to work together. To companion plant, people will get multiple plant species and keep them in the same garden. You have to be careful of what plants you keep together though because they won’t all get along.

You’ll want to be selective of which plants you keep together and which ones you don’t. There are a lot of plants out there that will help each other to thrive. However, there’s also a lot of plants out there that will harm one another.

Companion planting is still a pretty new concept, so there aren’t any set rules when it comes to garden planting. Most of the research that has been done has been done on vegetable crops for farming.

Despite this, many gardeners have worked over the years to figure out which garden plants work best with each other. Much of this comes down to trial and error, and devoted gardeners have already done a lot of the work.

It’s safe to assume that all plants can benefit from companion planting. It just takes some work to figure out which plants go together and which don’t. We don’t know how some plants will react to others yet, but that’s all part of the process.

Fortunately, a lot of trial and error has already been done with peppermint. Gardeners have a good idea of which plants go well with peppermint and which ones should be avoided. This makes your job a lot easier.

What Are The Benefits Of Companion Planting?

Some people will argue that you shouldn’t companion plant. They say that it’s better to grow each species of plant on its own. However, plants in the wild don’t have this option, and they’ve been doing great for millions of years.

Wild plants have learned to adapt over the years. They have learned to live with other plants, for better or for worse. Some plants have figured out how to benefit others while also benefiting themselves. Other plants simply compete for resources and will kill any other plants in their way. Garden plants are the same way.

For the plants that do work together, there are lots of benefits they can reap from one another:

Attracting Pollinators

People who are struggling to attract pollinators to their garden should consider companion planting. There are a lot of sweet smelling plants that pollinators love. Try placing plants that don’t smell as nice next to them. They will reap the benefits of those pollinators too.

Some of the most common pollinators attracted to gardens are butterflies, bees, and hummingbirds.

Deterring Pests

There are also a lot of plants that are good for deterring pests. Peppermint is one of them. Peppermint’s odor is very strong and powerful. This is one of the reasons why people love peppermint so much.

For insects and rodents, the smell is abhorrent, and they want nothing to do with it. If you’re worried about bugs getting at your plants, you’ll want a companion plant that is good at repelling.

Increasing Nutrient Supply

Some plants are good at providing the soil with nutrients. This can be beneficial to other plants that are lacking those particular nutrients. For example, beans and peas put nitrogen into the soil. This helps fix any nitrogen imbalance in the soil. It also helps plants grow that need extra nitrogen.

Providing Shade

There are many plants that do well in partial or full shade. For shorter plants, it’s easy to naturally provide them with the shade they need. Many taller plants need direct sun. They will reach toward the sky and will gladly overshadow and shorter plants you grow beneath them.

Plants like beans and lettuce will do wonderfully growing beneath the shade of plants like corn.

Weed Suppression

Weeding is probably the most dreaded part of every gardener’s day. With the right companion plants in your garden, you can cut down on the amount of weeding you’ll do drastically.

The best thing you can do is to plant low-growing, creeping plants in the empty spaces of your garden. When there is space in between your crops, it makes it really easy for weeds to crop up.

What To Consider When Looking For Peppermint Companion Plants?

When searching for a good companion plant for your peppermint, there are a few things to consider.

Pest Control

Peppermint is a great plant for pest control. That delicious, cool scent that we love so much is hated by insects and rodents. If you plant mint in your garden, it will deter pests.

Many pests will not even enter your garden when they smell peppermint. Those that do are likely to become confused. Their senses will go into overload and they might not be able to find the plant they want to snack on.

Some of the pests peppermint repels includes ants, aphids, cabbages loopers, cabbage flies, and flea beetles.

Not only do the bad bugs hate the smell of peppermint, but the good bugs like it. While keeping pests away, peppermint will also attract beneficial insects and pollinators to your garden.

Roots

Peppermint is a very quick-spreading plant. It has thick rhizomes that grow underground and can take over a garden quickly. I recommend keeping your peppermint plant contained so that this isn’t an issue. However, if your peppermint is free to spread through the garden, there are some plants you’ll want to avoid.

Plants with thin and delicate root systems won’t work well. The peppermint will simply rip through the roots and kill the other plant. Rosemary, for example, has a delicate root system and doesn’t make a good companion plant for peppermint.

What To Avoid

Generally, you won’t want to plant crops together that are too similar. If they have the same nutrient requirements, they won’t do well.

If they need the same growing conditions, like light, they won’t do well. If they have the same root system, they won’t do well. You get the picture.
