Yesterday I added three bags of these number two wood chips I purchased at a Gardening center. Looking at the chips last eve after they were spread out, I decided to just go ahead and do the entire area between the fence and the rocks. Why not? The chips are really cheap and will build the thickness of the chips back up.
Once I complete this, I’m going to purchase about 100 pounds of the rock that’s back there now. There are some thin spots where the rocks have apparently sunk into the ground which is expected. Once this yard was rebuilt very early 2019, keeping it up and looking nice is something I can do regardless of my back issues.
