text: could grass grow through the liner of my pool? i have one of those blue pool that you blow up the ring and then put the water on and it goes up. well i was told that even tho you put sand under the pool and then put a tarp over the sand that grass will still grown thrrough my liner it's pretty unlikely but i'm really not too familiar with those kinds of pools. i was thinking your actual pool so my initial reaction was "no way!" but i'm not too sure. before you go in just leave it out in your yard in a chady spot or something and see if the grass grows through. that should answer your question even if it does take days to play out.
