Intro to Dahlias (Session 3): Dahlia Processing, from Purchase to Frost and Beyond Dahlias are some of the most beautiful flowers, loved for their wide variety and brilliant colors. In this final session of our 3-part Intro to Dahlias series, you’ll learn how to prepare your tubers for overwintering so you can enjoy strong, healthy plants year after year.
