I use grass clippings all of the time to smother weeds and kill them. I've been doing it all summer killing weeds near my inground palms. It occured to me that the grass could make a great ground insulator. It's thick and as it decomposes it creates methane gas which equals heat. Any ideas on if this is a good idea. I've got about another 4-5 weeks of grass to cut. In fact my lawn is greener and thicker than it's been all summer.

thanx,

Andy
