I started this post a while ago and can now update it:
I hate edging gardens. I don't know anyone who does. The flower bed surrounding the front of the house has stones edging it, making moving close very difficult and giving lots of places for weeds/grass to get into the garden. We found some neat looking stuff on clearance at Lowe's. Hopefully; it will work well and Alan will be able to mow up to the garden.
