Dry river bed
I'm not exactly sure if this is the board I need to post this but I hope someone can help. I have a drainage issue with one side of my house and the entire edge of my very long flower bed (almost 160') gets washed away with any heavy rains. I used left over river rocks to make a dry stream bed in the edging area, which directs the water to behind the fence.
The problem is that although the river rocks keep the soil from washing away, the more it rains, the rocks are getting covered with sand/soil, etc. They getting buried. How do I keep this from happening?
This picture shows the main area with the problem.
