I like to keep my mint plants in pots. In the past, I've sunk terra cotta pots into the ground, holding individual plants. They do a good job of corralling the mints, while keeping the roots well-watered. However, as you can see, the pots fall apart after a while, in our climate. And it just doesn't look so nice after a full season or two.
So, time to see what I can do with this area.
I bought a larger pot, one of those all-weather, concrete-looking pots. In it, I placed 3 tall-ish plastic pots (they look like 1-gallons).
I filled the outer pot with plenty of soil, then moved the mint plants into each of these smaller inside pots. I did have to root-prune one of the plants, and cut the whole thing in half, as it wouldn't likely do well, simply transplanted. But I do like how this project turned out.
In summer, I grow the mint in the shade of a blueberry bush. Our yard can really bake. But now I have the option to bring the mint plants up to the deck come fall, which I might find quite handy.
When we first moved into this house, the previous owners had mint growing in the front garden, only it was allowed to "roam". I spent the better part of every morning, for one entire summer, eradicating that mint from the yard. My aim is to never go through that, again!
