What do I do now
Hi need some advice re tree peonie again inherited when we moved in, last year as you can see it was glorious but very leggy not really self supporting.This year 1 solitary flower head. I would like to know when and how to prune it, if pruning is the thing to do. It is such a stunning plant with flower heads the size of a tea plate.
In swedish, but you can see the pictures.
