it depends entirly on what you want to prune , if you were to tell us we can tell you when for each. and welcom to GOY ,and if you do not know the names of some things a photo of the plant and leaf.will give the gardners on the site a good idear and they will be able to help you.

Your spring will be earlier than anywhere else in the country - it starts in the west and works its way up and across the country! Nonetheless, as Cliffo says, it depends what you want to prune - fuschias and hydrangeas should not be touched yet, for instance. It's okay to prune Wisteria though.

I would wait till spring March/April as you do need to identify your plants because some plants wont flower that season if you prune in the spring etc.
