Wood or gravel
Im leaning towards gravel as I have an unlimited supply in the creeks on our land. My beds are all grass with whiskey barrels, wash tubs, and old milk cans used as planters so I feel like the gravel will look better.
I'm also curious which would be the least inviting for snakes. We just killed the first copperhead of the year while weedeating in the ditches along the road, less than 20 yards from the house. With three young kids, I dont want anything that would draw more snakes in.
