Cistus pulverulentus (sunset)
I have a Cistus pulverulentus (sunset) which flowered very happily all last summer in a tall pot against a west facing wall. It has suffered, like many plants, from the long harsh winter + umpteen frosts: many leaves (but not all) are brown + withered partly or fully.There is still life there but I want to help it regenerate. Should I prune off the damage, if so how much can the plant bear? I've heard they don't like pruning but also heard more established cistus growing in the hotter climes that they like (eg California) CAN withstand trimming and shaping. I think mine was probably only one or two years old when I got it last year. Can anyone advise please?
