We have an Embassy Century above ground pool with the metal corrugated surround. Got it put up 6 weeks ago but haven't had time for landscaping...the weeds and grass are already growing right next to the base of the pool. How bad is that? Is it essential that the first couple feet around the base of the pool be gravel, stone, etc. or can we let the grass grow and mow around it? I am ok with spraying weed killer along the very base of the pool since weed-eater could damage it. We did use a fabric weed-blocker underneath and it is flush with the pool surround.
