drainage for area confined by wall and clay/rock fill?
I have an area on the side of my house that is about 6 feet wide, and then there is a retaining wall.
If you dig more than 2 inches down, the fill is clay and gravel.
I doubt that there is any drainage for the plants after a heavy rain. I added some plants last month, and I am concerned that the area will turn into a plant killing bathtub when the rains come. The rhodies in the photo are veterans, all the others are new.
Would it be a good idea to drill a hole or two in the concrete wall?
The house is on a gentle slope, hence the retaining wall (not built by us).
