|How do you winterize vining roses on an arber? Thank You.|
|Some roses are winter hardy in cold climates such as yours and others need lots of TLC to get them through the winter. I don't know which type of rose you are growing so here are some general guidelines: If the rose is tied to a wall, trellis or fence, untie the climbing rose canes and wrap them in insulating material (the way you'd wrap the pipes to keep them from freezing). Then retie the canes to the wall, trellis or fence.
If you need to cut the canes back a bit to make it easier, go ahead. You must also cover the base of the plant with at least a foot of soil and added mulch.
Another way to do it is to detach the canes from the trellis and lay the whole plant down on its side on the ground, staking it in place, and then cover the whole thing with a foot or more, of soil and mulch, or other insulating material, such as burlap or foam insulation.
When the weather warms in the spring, gently remove the covering and retie the rose to its structure.
Best wishes with your climber.
