You probably don’t need us to tell you how stunning dahlias are. After all, one look at these giant, flamboyant flowers will prove as much. But when these blooms start to fade, you might start to wonder: Should you deadhead dahlias?

Dahlias offer some of the most beautiful flower heads out there. And while knowing when to plant dahlias and how to grow dahlias in pots will allow you to bring this idea to fruition, you also need to know what to do when your dahlias are in full bloom - and what to do when they’re not.
