Warning: Mints are Invasive Garden plants!
When you plant mint in your gardens, isolate the plants.
Mint is a strong, vigorous grower that will spread quickly and be challenging to manage if not contained.
The best way to control mint in your garden is to plant it in containers. You can place the containers of mint around your garden or bury the entire container in the garden bed. The pot will help contain the roots and limit the mint’s ability to spread.
Avoid Growing Mint Next To These Plants:
- Strawberry Plants
- Oregano
- Rosemary
- Basil
Strawberry Plants
Strawberries and mint plants are vulnerable to a disease called verticillium wilt. Planting together increases the risk of the disease spreading quickly through the entire garden bed. It’s best to avoid planting all varieties of mint away from your strawberry plants.

Oregano, Rosemary, Basil, and lavender
Oregano, rosemary, basil, and mint all enjoy different watering schedules and when planted together it makes watering challenging to manage. If planting mint near these other herbs keep them in a separate container so you can control the moisture levels.

THE BENEFITS OF COMPANION PLANTING
Companion planting brings a whole host of benefits to the organic home garden. All plants have beneficial partners who, when planted nearby, can help improve growth, taste, yield, and help control pests and diseases. Companion plants can help:
Attract Pollinators
Colorful flowers with strong scents and abundant food sources attract pollinators like bees and butterflies. Pollinators are beneficial for increasing yields.

Attracting Beneficial Insects
Marigolds attract helpful bugs like parasitic wasps, hoverflies, and ladybugs. These beneficial insects will help curb pest infestations.
Repel Harmful Insects
Like mint and lavender, some plants work well to deter common garden pests, such as squash bugs, asparagus beetles, spider mites, corn earworms, and tomato hornworms. Or the plants will attract harmful pests and work as a trap crop to keep these pests away from your veggies.
Help Improve the Soil
Some flowers like marigolds, help destroy root-knot nematodes that live in the ground and destroy plants from the roots. Other plants can act as a living mulch to help control moisture in the soil. In other cases, plants with large taproots, like carrots can help break up heavy soils and increase aeration.
Help Control Weeds
Densely planted leafy greens or low-growing flowers can act as a living mulch to prevent weeds and help retain moisture in the soil.

Companion Planting Can also Help with Disease Issues.
Diseases are spread more quickly through your garden when large groups of the same plant are grown together. Adding different plants can help break up groups and slow the spread of diseases like powdery mildew or blight.
