How far down in the soil do I place them??? That sounds like a neat idea.
My raised gardens are about 2 feet deep and I chunked up the diapers and dug them into the soil. They may be 8 to 9 inches maybe a bit deeper, from the top. In the hanging pots, I just cut the diaper to fit the the cocoa liner. I even use astro turf with the wire pots and put the diaper against that then the soil and flowers and strawberries. This is the first time I’ve done it but I’ve heard it works.
