Hi, I'm Stan DeFreitas, Mr. Green Thumb for askmrgreenthumb.com. When we talk about Knockout Roses, in some parts of the country, you may have to be worried about protecting them from the Winter season. Now typically in the South, you don't have too much of a worry, but where you do have areas, you want to get some type of a cover. You can buy most of these insulated covers at almost every nursery garden supply center. What you're going to do is take it out of the package, and you're usually going to try to cover the rose completely, usually get a couple bricks or something, cover it all over this Knockout Rose. We're going to take it and kind of cover the whole plant to the point that we have it all over the rose bush and down to the ground. If you can save the radiant heat from the ground, that means let the sun get in during the morning, then cover it over, you'll be able to save all that energy and you help to insulate the rose bush from the hard freeze. Now, these will take a pretty good amount of cold, but if you're going down to where it's going to be down, way down below freezing, protecting some of the, protecting the Knockout Rose with a cover is a grand idea. If you're really in doubt, take a treble light and put a treble light underneath it, and put that cover to help give you an extra five or six degrees. For askmrgreenthumb.com, I'm Stan DeFreitas.
