Clematis triternata rubromarginata

Hello,

I’m planning to move my clematis TR this autumn, as it’s not doing too well in its current spot (too shady, too much competition from other large plants).

Does it get too large for a rose arch, do you think?
Has anybody ever combined it with a climbing rose at all? Did it work and which rose did you go for?

🙏🏻

    I grew this clematis in my last garden, up a hamamellis but neither survived a particularly nasty spell of cold - 25C nights we had for 2 or 3 weeks one winter.

    I doubt you'll get anything like that in north London so have a read of this article below and then go for it.   Move it in autumn when the clematis is dormant and make sure you get all the root ball and plant it deep with plenty of well-rotted compost and soil conditioner.  Water well before and after moving and be ready to tie in regularly when growth starts next spring.

    Thanks!
    Yes, I’ll be sure to do this in autumn.
    Do you think that a standard sized rose arch is too small for it though, as it seems to reach 4m? I’d love to put it somewhere where it has space, but I have so many plants that I can’t find a single other spot for it 😁

    Depends on the size and width of the rose arch and hetehr or not you catch the stems in time to train them round or across and up.  Mine never got to 4m, more like 3, but it will have started growing later than yours is likely to do as spring will be earlier in London than in my old garden in rural cental Belgium.

    Thanks Obelixx.
    Mine gets to about 3m as well currently, but is hardly flowering and tends to top wilt back to about 1m from the ground - probably lack of water as too many shrubs close by.
    This year I’ve watered judiciously and it still has lots of green on it, but no flowers…time for it to find a new spot.

    Clematis are very hungry plants so watering alone may not help.

    Whether you move it or leave it try giving it liquid rose or tomato food for now and then give it a good dollop of slow release fertiliser every spring and a mulch of some soil improver such as garden compost every autumn.

    Will do.
    Then I’ll leave it in peace until autumn, when I’ll be moving it.
    Thanks.

    I had one for quite a few years, would just cut it right back in Spring and it would trail over the obelisk and onto a shrub,  this year along with a few other plants,  it died in the cold winter/Spring.

    Oh that’s such a shame!
    I hope mine doesn’t suffer the same fate…
    Currently trying to decide what other climber (over a large, squarish pergola) I could combine it with - possibly a climbing rose…any excuse to go to the garden centre 😉

    @dappled shade - have a look at the DA Claire Austin, creamy white/pale lemon centre. It does very well (a bit too much!) up the side of my arbour and carries masses of flowers.

    @dappledshade. I hope yours survives,  you’re warmer there than here.
