Sorry to take so long to get back here. Thanks so much for your advice. I mixed 1 third top soil, 1 third John Innes 3 and 1 third multi-p.
However, here's a question. The wind has been brutal for two weeks with occasional hail but settling now to normal wind and a little sunshine during the day. I've had to put both pots together for the time-being to get a little shelter - although the garden is really exposed. Surrounded on all sides by high flats but the wind comes over the roofs and circles around all day from all directions.
The nearest rose in a pot in this photo is 'Lady of Shallot'. A climber, but I saw some photos and read some websites which have it just growing normally in a pot and not climbing. I'm planning to do this now. However, if you look at the photo there is one substantial shoot sticking out horizontally. Presumably (?) that would be a strong leader if placing it horizontally to climb? As I'm not going for 'climb' I'm wondering what should I do with this shoot - should I cut it back? There is no new growth on it - and I can't tell if there ever will be. I'm not sure if I'm supposed to just leave it as it is.
Also, if I just leave it to grow normally - should I remove those insubstantial miniature trellises the roses came attached to, if I want the rose just to round out?
Sorry to ask such naïve questions - I've never potted roses before and I haven't a clue how to support them, or not support them as they are - and I don't want to do something stupid and ruin them!
