need a solution to a garden path drainage problem?
I have added crushed limestone to my garden paths. In one area I have quite a bit of surface area (paved driveway and grass) draining down into one of the paths. With a heavy rain, it creates ruts in the crushed limestone and washs the crushed limestone away.
I can't change the levels in the drainage area without causing other problems, and the path is a convenient way to divert water to a drainage ditch.
My proposed solution is to insert 2x4" boards across the path to reduce the waters ability to wash away the limestone.
Alternatively I could embed stones in the path to slow down erosion.
I had the limestone added a few months ago. Is it possible that it was just never packed down properly?
Any suggestions are comments on my ideas?
