I started a thread here in 2006 about a very ill peace lily... http://www.botanicalgarden.ubc.ca/forums/showthread.php?t=14812 ...which I can now say is thriving, having survived several inept dividings and repottings till I took the advice of the late Steve Lucas and used the mix of soil he recommended on his web site. I keep it (them, actually...) very wet and all three are making new leaves and flowers. However, I've been overun with hordes of stinging little bugs who seem to be coming from the flowerpots my peace lilies are in. A couple contributors to another forum claim they solved their bug problem by covering the offending soil with a layer of sand, which apparently the bugs cannot get through to breed. My question is this: Does anybody know if that will be safe for my peace lilies? I'd rather use that than insecticides! Thanks!
