Q.Knockout rose in alaska
I bot this rose at home depot in kenai alaska. How should I care for it in winter, we can get down to -20 for short periods at nite and 5 daytime.
Tell me there is hope!
There is indeed hope. I live in Northern Colorado where we get cold winter temps and dry cold windy conditions. Not as cold as where you are but it is possible to grow and enjoy roses in your climate. Here is a link to an article on this subject for you: https://www.gardeningknowhow.com/ornamental/flowers/roses/roses-winter-care.htm . Water the rosebushes with some water that has a product called Super Thrive in it several times prior to the onset of the winter season there. It will help them deal with the extreme cold of the winter dormant period.
