Title: Removal of invasive mints
Answered by: Nan Hampton and Joe Marcus

QUESTION:

How do I remove common mint from my garden? I removed the previous years plants and tilled the soil. This year they came back more than before.

ANSWER:

Mints are very invasive. They spread by putting out shoots from the roots or underground stems. Sorry to have to tell you this, but the way to get rid of them is to dig or pull them up. To completely eliminate them you need to get the roots out of the ground. it will take a while, but if you are persistent you can remove them all. However, if you would like to keep a few mints around, you can grow them in containers or plant them in large sunken pots in the ground to keep them from spreading where you don't want them.
