Growing R. Mme Alfred Carriere into a birch tree?
I love this rose and can't imagine my garden without it. However, when I bought two of them I really didn't understand how much space they need! The arch that one of them is growing on is nowhere near big enough and the poor plant is being mullered every year with really drastic pruning to force it to fit. There's no larger structure that's suitable so I'm wondering about letting it grow up a birch tree - the only one big enough - that I have in my garden. Would this work do you think? I'm assuming I'd need a stout pole or similar to guide it up into the tree but would it find its own support once it's in the canopy or would I need to keep on tying it in (which wouldn't be practical)?
