You should prune them in late spring after flowering has finished. Cut them back to about 10 cm (4 inches) from the ground, but always leave some leafy growth on the stem. Do not cut it so that only wood remains. This will encourage a bushier plant that will grow all summer and be ready to bloom again the next spring.
