My bottle brush has got so big and struggling that it needs pruning. When and how. ????????
I meant to say scraggly.
Usually done after flowering, light prune only, dead heading and removing damaged wood is the norm. Can't say I come across them that often and not a shrub I really like.
I don't like it that much, been spoiled by the ones in Australia, but it fills a space. So will prune it. Thanks for your response.
Thanks, mine is looking leggy and probably past its best, but I will prune it as suggested and give it another year.
You have given me an idea, I might prune all the underneath of mine and gently prune the top to lift it up, it's the underneath that's scraggly.
I did that some years ago with a Photinia Red Robin, it's now a lovely 7' standard, but I would not have thought to do it with the Bottle Brush, thank you.
