I didn't cut any of my perennials back because they were flowering in December

What should I do with them now? These odd seasons are confusing me and my plants.

I often don’t! I find they start to grow new shoots down at the base so I then cut it down to that. I agree though, things bloomed on so long last year. Think the only things not to prune are early flowering clematis. Things like perennial geraniums could do with a quick tidy and cut back, lots of mine are still green and didn’t really go dormant. What plants are you thinking of?

I'm cutting everything back this week (apart from those which are due to flower in spring or early summer, obviously). I always leave growth on over winter, for wildlife, but now spring is just about to burst into action and everything will be starting to get little green buds.

Mid/late season clematis, decorative non-evergreen grasses, perennials, shrubs, climbers, old annuals to be cleared out - it's all coming down now.

I'm in the same position OP. Can I cut back wisteria now? They are relatively new plants which have not yet flowered but have messy branches everywhere.

redhat yes you can, apparently it's best to prune wisteria twice a year, now and after flowering; rhs
