I have a number of clematis which I always prune in late February. But this year, although it's only mid-Jan, we've had well above average temperatures and all the plants are showing lots of buds. So should I prune them now - or leave them another five weeks or so? I don't want them to become leggy if I leave them too long.....advice appreciated.
