How deep do I need to make step gardens?
I am wanting to make these step gardens for my back yard but just two steps and not three like the picture. I was curious how deep should the steps be and how long front to back? I was going to make drainage holes and put in gravel at the bottom and soil on top. Also, does the rocks and soil sound right? Or should I have something else in there too? Any advice is greatly appreciated, thank you!!
