Warning: Mints are Invasive Garden plants!
When you plant mint in your gardens, be sure to 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:

In other cases, plants with large taproots like carrots can help break up heavy soils and increase aeration.
