Looks like a good start for the season, Rose.
Please offer our thanks to your son for helping get the task completed. It is important for our young ones to become accustomed to helping with home and family chores - it helps them establish their routines easily when they get out on their own.
Hope your crops produce well, unhampered by chewers large or small, or diseases.
@vgkg - if you have fence with posts beside the pieces lying on the ground that need to be moved for mowing, would it work to just lift the edge far from the fence to stand it alongside the fence and use a few pieces of wire or string to fasten it there, then drop it back down after mowing?
