Pruning a climbing rose
Can someone give some advice on pruning climbing roses (or point me in the direction of a good book for it). I bought this rose last year and want to train it up the wall and then over the doorway with flowers from as close to the base upwards. I’m not sure how to prune it though. I seem to have lots of thin stems from the bottom which are starting to cross so I know I need to sort that out. I’m tempted to cut the newer, thinner ones off instead of tying them in, so I just have one or two bigger stems but I’m worried I’ll end up just having stems with no leaves/flowers going up the wall. Or can new leaves/flowers sprout from the sides of old stems?
It would be great to have a book showing the structure of different plants to help with pruning/training etc.
