All advice I have read advises that I prune my Buddleia Bush ‘in early spring’.

I am confused a little as the photo will show that, at the moment, (almost early spring) the bush is in full blossom.

I assume that any pruning for next year would be done after flowering, and if it flowers through the Spring and Summer, the pruning would need to take place after that – late Summer or early Winter.

Also there are a few yellow leaves on the bush. Is that a deficiency of some kind?

I would appreciate any advice you could give me. Many Thanks.

I completely agree that almost all flowering plants are best pruned immediately after flowering (with the obvious exception of Fruiting plants). Do this with your Buddleia. These plants can look a bit scruffy if not pruned annually. Overall, your plant looks 100% – the yellow leaves are just being jettisoned by a healthy, rapidly-growing young plant. Don
