My mother-in-law has a pieris in front of her door that is outgrowing its space. It has had an attractive natural shape but now is getting a bit gangly-looking. I think she would prefer for it to keep a natural shape as opposed to shearing it into a ball. Looking at it, the leaves are smaller than some pieris but larger than the dwarf varieties, so I would say it is a semi-dwarf variety. It has not outgrown its space for probably about 20 years. Any ideas for the best way to prune to keep its natural shape? She is open to replanting, but of course pruning would be easier. How would you prune this?
