climbing rose question
I have a clinbing rose Ena Harkness ( stunning red with fab scent) and it is growing up the pergola leg and beginning to go over the top. It had 3 main stems but because all the flowers were more and more higher up -I cut one main stem back to the ground hoping it would sent up a new shoot and I would be able to tie this in and begin to have flowers lower down. I did this last year, but no new stem appeared. So my question is- do I cut back 1 of the 2 stems remaining in a hope that next year I would hopefully jolt the rose into sprouting a new fresh stem-? but then I will cut off lots of top growth and Im sad at having to do that. I dont know what to do to get the best results from my climbing rose. Please help.
