Controlling the spread of mint can be a challenge, as the plant has a tendency to send out underground runners and quickly take over an area. However, there are effective methods to contain mint and prevent it from spreading uncontrollably. One of the best ways to achieve this is by planting mint in a pot and then sinking the pot into the ground or placing it within a larger container.
By using a pot, you create a physical barrier that restricts the spread of mint’s invasive roots. Start by selecting a pot that is at least 12 inches deep and wide to allow enough space for the mint to grow. Make sure the pot has drainage holes to prevent waterlogging.
To begin, fill the pot with a well-draining potting mix, leaving about an inch of space below the rim. Then, carefully remove the mint plant from its original container and gently loosen the roots before placing it in the pot. Position the plant so that it sits at the same depth as it was in its previous container.
Once the mint is planted in the pot, you can choose to bury the pot directly in the ground or place it within a larger container. If you decide to bury the pot, dig a hole slightly larger than the pot’s diameter and deep enough so that the rim of the pot is level with the soil surface. Place the pot in the hole, ensuring that the rim is flush with the ground. This prevents the mint from spreading by sending out runners beyond the pot’s boundaries.
If you prefer to use a larger container, select one that is at least 18 inches in diameter to provide ample space for the mint’s growth. Place the pot inside the larger container, ensuring that it fits snugly. This method is particularly useful if you have limited garden space or if you want to move the mint around easily.
To further prevent the mint from spreading, it is essential to regularly maintain the potted plant. Every few weeks, give the pot a quarter turn to prevent the roots from escaping through the drainage holes. This simple action helps to keep the mint contained and prevents it from taking over your garden.
Additionally, be mindful of removing any stray runners or shoots that may escape the pot. If you notice any new growth outside the boundaries of the pot, simply trim it back or carefully dig it up to prevent further spreading.
The best way to stop mint from spreading is by planting it in a pot and either sinking the pot into the ground or placing it within a larger container. By doing so, you create a physical barrier that restricts the invasive roots of mint from spreading beyond the boundaries of the container. Regular maintenance, such as rotating the pot and removing any stray growth, is also crucial in keeping mint contained.
