In an attempt to keep our yard slightly neat looking in trying to figure out what to put around the pool? I understand it’s mostly recommended to leave it be but I’m hoping to find something to discourage a lot of grass/weeds but also not just plain dirt? I initially was thinking of planting hostas around it but saw that’s probably not a great idea, I’m nervous to do rock as I don’t want anything creeping under the liner and creating a hole.. I also have 3 dogs so I’m nervous about them jumping up onto the steel frame to nose around. Tips?
