Gravity pushes out our little landscaping wall every year. Since we somehow forgot about it last year (maybe because of a wedding or something like that), we had to move the wall back about a foot. Another year or two, and the primrose we had planted there would have been across the path. Pat moved the primrose to one of our mini berms (alright, I made up the term). The whole project took 20 minutes. We had plenty of time to plant some more plants, weed and mow the backyard. In another 3-4 weeks, you won't see any ground in this hosta bed. The hosta covers everything.
