Another option…
It is quite common with gabions to find one that has a rectangular shape.
The soil is protected and kept inside at its highest quality. The stones also separate it from the outside influences like wind, insects or other guests that are not welcome.
The best feature of all is that the plants have plenty of space and air to grow.
I always suggest getting a planter that can store the plants on a higher level than the ground. It would be much easier to arrange it without bending too much. Perfect for people suffering of back pain.
