Just that really.
Years ago before I knew anything about plants (and I’m still learning by trial and error) I lived in house that already had a cistus in the garden. It was gorgeous and I used to hack it back hard at the end of flowering (as it used to get so big) it used to come back every year, with extra growth and an abundance of gorgeous flowers. I loved it and so I’ve planted a few in my garden a couple of year ago. They’ve now got quite leggy and there’s less flowers but when I googled I see the advice is not to prune too hard? As I said I garden by trial and error (currently moving Lupins to the bit where there are a lot less slugs 🙄) but I’d still like to not kill off anything accidentally!
