I've got a couple of Cistus bushes, about three years old and three
feet high, which are looking a bit leggy with a lot of bare wood lower
down. Ideally I'd like to prune them back to about six inches (i'e.
beneath all the green shoots) to make them bush out again. But I
remember reading somewhere that Cistus don't like being pruned hard.
Should I give it a go or will it just kill them?

thanks

Robert
