Osteospermum repotting advice, please

B3B3 Posts: 25,155
My osteospermums have been flowering in the porch all winter.
I've moved them outside and will prune them hard back. They are all still in full flower but a bit leggy.
My question is:
When I repot them, can I root prune them a bit?

    No chance of putting them into bigger pots if they are pot bound?

    They're, already in big pots. Some are a few years old and have been repotted before.
    If I can't root prune, they'll have to make do with top dressing.

    I keep mine for years. I repot and it's true, I end up with very big, heavy pots. I have never tried any serious root pruning but I take cuttings when I sense that the plant is getting too big to handle for another year.

    Does one cut any oesteospermum back hard?

    I will cut them back to a few sprouted buds. That's what I should've done in the autumn, but I couldn't bring myself to cut all the flowers off.
    I don't know if I've damaged them. We'll see. :)
    Ps. I don't know enough about them to give any advice but that's what  I usually do.

    I cut mine outdoor ones hard every year and they do very well.Blooming all through 'The Beast from the East' as well.
    I have root pruned ones in pots as well.
    I get loads of cuttings as well so I stick them in the ground as they are and away they go!

    @madpenguin I saw your comment above and potted up some osteo prunings/cuttings and they have rooted! I checked today and they have a great system and have put on loads of new leaf - in just a month. Woo hoo. Thanks for the tip. I with def'ly be doing this in future. I have loads of new salvia too. So satisfying to get so many free plants.
