Mint. It's that fragrant herb that brightens up your mojitos, adds a refreshing touch to salads, and can even be used to soothe a troubled tummy. But, as many gardeners discover, mint is also a bit of a bully in the garden. It spreads aggressively, often crowding out its neighbors. So, the big question arises: What can you actually plantwithmint without it taking over the entire show? Let's dive in and uncover the secrets to companion planting with this vigorous herb!
Companion Planting with Mint: Finding the Right Partners
When considering what to plant with mint, it's crucial to understand its growing habits. Mint is a vigorous spreader, primarily through its underground rhizomes. This means it can quickly colonize a garden bed if left unchecked. Therefore, the key to successful companion planting is to either contain the mint or choose companion plants that can hold their own against its aggressive nature. We'll explore both strategies.
Containing Mint: The First Step to Successful Planting With Mint
Before even thinking about what to plantalongsideyour mint, consider containing it. This is often the easiest and most reliable way to prevent it from becoming a garden pest. Here are a few options:
- Potting Mint: This is the simplest solution. Plant your mint in a pot, either a decorative one on your patio or a more utilitarian pot buried in the garden. Make sure the pot has drainage holes.
- Burying a Barrier: If you want to plant mint directly in the ground, create a barrier using plastic edging, old buckets with the bottoms cut out, or even thick landscaping fabric. Bury the barrier at least 12 inches deep to prevent the rhizomes from spreading underneath. Ensure that several inches of the barrier remain above ground as well.
- Regular Pruning: While it won't completely stop the spread, regular pruning of the mint stems and removing any runners that appear can help keep it in check. This requires consistent effort.
Once you've taken steps to contain your mint, you can start exploring companion planting options. Let's delve into what plants thrive nearby.
What Plants Benefit From Growing With Mint?
Surprisingly, despite its aggressive nature, mint offers some benefits to its neighbors. Its strong scent repels many common garden pests, making it a valuable companion for susceptible plants. Here are some key companions that can benefit from having mint nearby:
Brassicas (Cabbage, Broccoli, Kale, Cauliflower)
Brassicas are often plagued by cabbage moths and flea beetles. Mint's strong scent can deter these pests, protecting your valuable crops. Interplanting mint amongst your brassicas can significantly reduce pest pressure. Consider planting mint in pots and spacing them amongst your cabbage family plants.
Tomatoes
Tomatoes are susceptible to various pests, including aphids and tomato hornworms. Mint can help repel these pests, leading to healthier tomato plants. Furthermore, some gardeners believe that mint enhances the flavor of tomatoes, although this is largely anecdotal.
Peppers
Similar to tomatoes, peppers can benefit from mint's pest-repelling properties. Aphids and flea beetles are common pepper pests, and mint can act as a natural deterrent. Ensure good air circulation around your pepper plants to prevent any issues with humidity that mint might contribute to.
Eggplant
Eggplant is another member of the nightshade family that can benefit from mint's protective qualities. Flea beetles are particularly fond of eggplant, and mint can help keep them away.
Roses
Roses are beautiful but often attract aphids and other pests. Planting mint nearby can help keep these pests at bay, allowing your roses to thrive. Plus, the contrasting scents of roses and mint create a lovely aroma in the garden.
Strawberries
Mint can help deter slugs and snails, which are common strawberry pests. It also acts as a ground cover which helps with moisture retention. However, be sure to heavily contain the mint to keep it from invading the strawberry patch and competing for resources.
Plants That Can Hold Their Own: Companions That Can Compete With Mint
While containing mint is the safest approach, some plants are vigorous enough to coexist with it without being completely overwhelmed. These are generally plants that are already relatively robust and can tolerate some competition for resources. Consider these companions when you're thinking aboutwhat to plant in combination withmint:
Raspberries and Blackberries
These brambles are vigorous growers themselves and can often hold their own against mint. They have extensive root systems that can compete for water and nutrients. However, keep a close eye on the mint to prevent it from smothering the brambles' lower foliage.
Other Herbs
Certain herbs, such as rosemary and sage, are fairly robust and can coexist with mint, especially if the mint is somewhat contained. However, avoid planting delicate herbs like basil or cilantro near mint, as they are likely to be outcompeted. A good strategy is to pot these herbs instead.
Large Shrubs
Established shrubs with deep root systems can generally tolerate the presence of mint. The key is to ensure that the shrub is already well-established before planting mint nearby. Avoid planting mint too close to the shrub's trunk to prevent excessive moisture buildup.
Plants to Avoid Planting With Mint
While mint can be a beneficial companion for some plants, it's important to avoid planting it near certain species that are particularly sensitive to its aggressive growth or that might be negatively affected by its allelopathic properties (the release of chemicals that inhibit the growth of other plants). Here are some examples:
- Asparagus: Asparagus is a slow-growing plant and is easily outcompeted by mint.
- Onions and Garlic: Mint can stunt the growth of onions and garlic.
- Delicate Greens: Lettuce, spinach, and other delicate greens are likely to be smothered by mint.
Beyond the Garden Bed: Using Mint for Pest Control Around Your Home
The benefits of mint extend beyond the vegetable garden. Planting mint around the foundation of your home can help deter ants, mice, and other pests. You can also place dried mint leaves in cupboards and drawers to repel moths and other insects. Crushed mint leaves can even be rubbed on the skin as a natural mosquito repellent.
Fact: The essential oil in mint, particularly peppermint, contains menthol, which is a natural insecticide and repellent. This makes it effective against a wide range of pests.
Important Considerations for What To Put With Mint
When decidingwhat companion plants for mintare suitable for your garden, consider these factors:
- Your Climate: The ideal companion plants will vary depending on your local climate and growing conditions.
- Soil Type: Different plants have different soil requirements. Ensure that your chosen companions have compatible soil preferences.
- Sunlight: Mint prefers partial shade, while some of its companions may require full sun. Choose plants that can tolerate similar light conditions.
- Watering Needs: Consider the watering needs of both the mint and its companions. Avoid pairing plants with drastically different water requirements.
Ultimately, the best way to determine which plants are compatible with mint in your garden is to experiment. Observe how the plants interact and adjust your planting strategy as needed. Happy gardening!
