Pruning is best performed during the winter, before new growth begins.
Removing spent blooms at the base can keep a plant looking tidy without sacrificing wood on which flowers form.

How & What to Prune
Remove dead, diseased, or damaged wood.
Remove or shorten crossing branches.
Cut back all remaining branches to as low as ten inches from the ground if the plant is a focal point of the garden or to as low as 24 inches from the ground if the plant is in the back of a garden or along a border. Once this woody structure is established, cut back branches each year to their two lowest buds. Cutting back more severely to maintain a desired woody structure typically stimulates new growth.
