QuestionHi this is the second summer for my sub-zero rose "Hope for Humanity" and it is in full bloom. The problem is that the large canes seems to be growing horizontally. This rose is to be a low growing ever blooming rose approximately 3' in height. Instead of standing upright the canes have created a hole in the centre of the bush as they fall sideways. The blooms are spectacular. Should I prune the canes to try and create a bush. Last year it was not pruned: only old blooms were trimmed off and the branches that grew this year from those canes have grown laterally from the top of the old cane. Thank you.
AnswerBecause Hope for Humanity has long pliable canes, many gardeners grow this rose as a short climber. You are right in that the canes look like they are trying to grow horizontally and make lateral growth from the top. This is the way the rose wants to grow. If you cut the canes back to try and make them studier then they will just flop over again. This is a rose that was bred by the Department of Agricultural in Canada to honor the Red Cross.
