Clematis is already forming buds - when would be the ideal time to prune?
I'm trying to work out when I should prune my Clematis (group 3 Sally evipo) ideally.
I'm supposed to wait until after the last frost, I think. And to cut back to just above a healthy bud about 30cm from the soil.
But it's already starting to form buds for the past couple of weeks, do I just carry on waiting?
Last year I left it rather late I think (around March), and cut off all the new growth, leaving only 30cm of wood at the bottom. But luckily it bounced back and produced lots of flowers.
I'm pretty new to this and it feels so wrong to cut off lovely new buds, but I guess that's how we are supposed to do it?
I'm in Oxfordshire so quite central. Wondering how to know it's the last frost, or whether to prune before that?
Thank you for any help.
