When we bought our house 2 years ago, the previous owners had planted mint in the ground, despite having a raised garden bad. My wife and I spent an entire afternoon taking back mulch and digging to remove the mint. We built a 2nd garden box and put it over the top of the mint spot, but I'm already seeing bits of mint poking up from under the box...
I think there's been a misunderstanding. I don't have anywhere to grow anything unless it's in pots. I'm talking about mint generally, and why people don't like it growing in ground versus in pots.
