Veilchenbleu Pruning - Help
I have a young Veilchenbleu rose that will be in its third spring flush this coming spring and I want to maximize its bloom, but I don't know when or how to prune this rose. None of my other climbers are once-bloomers so this is unknown territory for me. This rose has really taken off this spring/summer and is totally healthy, so there are no damaged or diseased branches to remove. It is growing against a six-foot privacy fence and my hope is to train it horizontally along an approximate 16 foot length of the fence.
