    Sally is much smaller than Bill Mckenzie @Balgay.Hill, it only grows to about 5ft. so I think that support should be OK.
    Dordogne and Norfolk. Clay in Dordogne, sandy in Norfolk.

    There are different ideas on feeding, I do feed mine twice a year when I do the roses, others do that and give extra different feeds up to flowering but I can't be bothered.  In fact in past gardens I don't think I did more than chuck a few chicken pellets at them and they were fine.
    I have feed mine but haven't munched yet as the soil feels too cold but will probably do it next week.
    Keep it a couple of inches away from the stems and at least a couple of inches thick.
    Water deeply once a week or more in dry weather, certainly now as we haven't had any rain.
    If you look at either Thorncroft or Taylor's websites they give advice on care.

    Thank you so much K67 this is so helpful. I will do that and have a look at the websites you mentioned too.
    I've only known mulch for protecting plants from frost, so this is new to me.
    Is the mulch this time to stop the roots getting too hot in summer, or to keep them moist?

    Both really, but it also feeds the area if you use manure, not so much with other mulches but does help with water retention. Make sure you water well before you mulch.
    There is a theory that the cool root run isn't necessary but mulching won't do any harm

    Very interesting, thank you

    My understanding is that group threes flower on the new growth, so it's generally advisable to prune them back in late winter else you'll just get flowers just on the end. It doesn't harm the plant not to prune but the plant can become woody over time.

    Just to update - I followed K67's suggestion, and did a pruning following each stem to leave some greenery on each. Untangled and tied some parts to the frame, gave it lots of water and some tomato food. Fingers crossed, it seems to be looking good.
