I would like to install steel or composite edging around my house. It will 3-4 feet away from the house and will contain a bed of river rock 1-2 inches deep. We do not have gutters and the house is on a slab. The soil is dense and drains slowly.
1. The steel edging is 4 inches tall. Can I install it below the ground so that it' only 2-3 inches above the ground?
2. If I install it below ground do I have to worry about water run off?
3. If I install it at ground level do I have to worry about water run off.
4. What can I do about the water run off
