I understand it is not good to prune a Cistus, I have carefully cut bits off for a couple of years and not killed it but it still looks scruffy and straggly. It is in a pot so it can be moved according to the weather/space available.
Previously had one planted out which was here when I moved in but it died when the tree that sheltered it fell down and left no shade and lots of rampant plants took over. No space for this one to be planted out, plus heavy clay.
Any thoughts on tidying it up please?
