I thought we were talking about bubble wrap? Isn't that plastic? Pardon if I misunderstood. The moisture from the rotting leaves is what causes the root rot that kills them. Sand actually probably may be part of the problem, since sand is very compressed, and does not allow for any air circulation. Maybe it would be helpful to know what kind of plants you're talking about. Massachusetts is probably much milder, but it's also very wet in winter. I don't cover the plants wet. Also, the fact that the styrofoam panels are flat allows air circulation under it. Also each plant is covered with 2-4" of dry sand.. Massachusetts winters can't be harsher than Chicago in terms of degrees below zero ----- Original Message ----- From: <santoury@aol.com> To: <pbs@lists.ibiblio.org> Sent: Monday, November 08, 2010 3:21 PM Subject: Re: [pbs] Reflectix >I did not see the original post - but plastic will rot anything under it. >People here in Mass. cover lawns with plastic, or even tarps, in order to >kill grass, and everything else, to re-seed. > People here use HAY for protection in winter.
