I just purchased a “Knock Out” rose bush at your Queensbury store and when I got it home discovered that it is for zones 5-11. We are in zone 4. My question is do you think it will winter over alright if I mulch and cover it well? I would appreciate any advise you can give. Thank you.

The USDA hardiness zone map currently show most of Queensbury as Zone 5a.  Click on the link and see if you can find you exact location.  FYI, the hardiness zones were redrawn  few years ago and everyone was moved to warmer zone designations based on more recent climate data.  In either case, the Knockout will benefit from some winter protection since you are on the edge of their hardiness range.
