cytisus "lena" broom

You prune it now, cutting each branch back to strong sideshoots (do not cut into the old wood). Remove any seed pods still left after the pruning - this will concentrate the plant on making new growth for next year's flowers

Thanks, have done as you advised this morning

My plant lost all the flowers. Looks between green and brown the branches. Do I need to prune? Has to be in a pot by itself? What happens during winter time?

do the pods of Cytisus lena have to be removed
