In this short video guide, Monty Don shows you how to deadhead plants that are in full flower in summer, such as chocolate cosmos (Cosmos atrosanguineus) and dahlias, to keep the flowers coming right into autumn. He explains how to tell the difference between a bud and a spent flower, how far down to cut the stems, and how often to deadhead plants.
