How to cut a Buddleja in autumn and spring?

West Somerset, England Eng

I cut this back too hard earlier this year, and although it has lots of shoots (thank goodness - I thought I'd killed it!) It is not going to flower this year, I suspect. Can anyone tell me how to cut it in the Autumn and prune it in the Spring please?

On plant Buddleja davidii




I think you are panicing, it looks to me as if it will flower albeit a bit later.You can them off a bit in the autumn and then hard in the spring they are very tough and reliable don't worry.

Thanks - you are very reassuring! Tell you later if it does flower. Usually, I don't prune things hard enough, this year I pruned this very hard as well as a cotinus which had obviously not been pruned at all for years. It has some new growth which looks O.K. to me. It's showing in one of my photos in the back of the border. I didn't have to worry about flowers on that!

My mother in law had an 8' Weigela in her small courtyard garden. Too big for the space, so after flowering I 'pruned' it for her! The largest stem was 6" in diameter and this was cut down to ground level. After a week the new shoots appeared on it, and it's shooting away quite happily

Hiya You've done nothing wrong. Buddleia are usually hard cut back, and I do mean hard, in February as the flowers are formed on new wood. Your plant will flower when it is supposed to - late summer, when it provides much needed nectar for butterflies

thanks Saina - I guess I did panic a bit because I had cut it further back than I normally do! I think there are some flower buds forming at the moment!

It's almost impossible to kill them with pruning! No matter how hard you prune them back they will always come back, just the flowering maybe put back by a couple of weeks at most.

Here they have been in flower for most of July. They are also prolific selfseeders & will spring up in the most unexpected & surprising of places. They are very commonly seen alongside railway tracks.

Yes, you're right, Balcony! I do prune hard, now.
