Thank youi weeal, I realise that these climbers, whilst very decorative for a few weeks can be a pain the proverbial, and that they do get into every nook and cranny. Each year I trim the leading edge to within two feet of any soffit, window etc. to ensure that it does not become too invasive. I would personally trim it to within one inch of the ground, and keep it at that level, but I am under orders from "she who must be obeyed" to keep it.
Thanks again
