Can I prune a climber down to the ground?
I have a Madame Alfred Cariere that's about 10 years old. It has two massive woody canes heading off to the left and one new shoot on the right side. The 2 woody canes now look pretty bad. What would happen if I prune to the ground, and just leave the one new cane? I'm tempted to shovel prune it, but I have a really nice clematis planted right next to it, and I'd hate to lose that.
