Stacked Herb Garden

4 Materials
3 Hours
We recently moved to a new house. Our old house had an isolated strip of land along the driveway, which we used primarily for mint. Our new house doesn't have any isolated areas, and because we know how easily mint can take over a garden, we needed another solution.

A few years ago, I found someone selling iron rods designed to stack clay pots on top of each other. The rods had been stored, unused, in the shed in the old house, but we found them again in the move, so I decided to put at least one to use. I normally grow a few different kinds of mint, so this was an easy way to keep mint from taking over the rest of the herb garden, as well as keep one species from taking over space devoted to less hardy species.

I have another rod like the one I used in this project, and I will probably try flowers in it.

The starting point
I picked up a couple of bags of garden soil for this project, as well as a few clay pots of different sizes. Because the rod goes through holes in the bottom of each pot, it's important to make sure that the pots have holes. I also got a large clay saucer to go under the largest pot on the bottom. Note that the bottom of the rod has a type of cage structure--it makes the rod stable, but it also provides support for the second pot. I also had four mint plants that I purchased at a local nursery, as well as some fresh mint from Trader Joe's that I rooted in a glass in the kitchen window.
First pot
The rod is designed to fit in the bottom pot dirt goes in around the rod. I waited to plant anything until after completing the structure so that I could see how much room there was for planting.
I stacked the pots before adding soil to all of them. However, I didn't start that way. I started with only four short pots, and I put soil in the second one after adding it to the tower. Then I realized I should stack them first to make sure I had enough pots. It turned out that the collection of pots I started with was a bit too short and the rod was going to stick out at the top. I picked up a couple more pots, took the soil out of the second pot, and started over again.
Once I had the pots arranged the way I wanted them, I added soil to all of them and put a separate mint plant in each pot.
