How to Prune Plumbago?

Cut back all leggy stems or branches that detract from the plumbago's overall shape after each flush of blooms. Make each cut 1/4 inch above an outward-facing leaf or lateral stem. Reduce pruning to just removing spent flowers six to eight weeks before the average first fall frost date in your area.
