Clematis Montana Grandiflora on an arch?

Hi all,

Am I being a tad optimistic putting this on a slender arch, as I know these try to grow very large?

I could possibly make another arch crossways to bear more weight...

    Montana is way too vigorous for that.

    Hmm. I thought so.

    Can I get away with it for this spring/summer season, then move it in autumn to somewhere with more space to grow like against the front of the house?

    You would be better off planting it in a better place now.

    Maybe Marble Arch would do so yes - plant it somewhere better now and plant it well - watering before, depth, soil improvement and watering and feeding afterwards.  Then it can get its feet down happily and you can give it the support it needs as it grows.  It will want to get to between 7 and 10 metres so train it well as it does grow.

    Okay, no love for bodging it this year. :)

    It won’t do anything much in its first year so there’s no point in planting it there now. 
    Either plant it somewhere where it can get established or grow it in in a large container until it can go in the ground.
