We just built two raised cedar beds, 19" H x 48" w x 96" L go grow a vegetable garden in our back yard. The beds are currently surrounded by grass. While I like the looks of it as is, I've been told that it will be hard to mow / weed wack around the beds without potentially hacking the cedar. Someone recommended that I do pea gravel around the beds. I'm unsure based on previous discussions on pea gravel that I've read on Houzz. I would greatly appreciate any suggestions. Thanks!
