Before planting, it’s important to know if your dahlia tubers are ready to grow—or headed for the compost bin! In this hands-on science and garden investigation lesson, students become garden scientists by learning how to evaluate the health of a dahlia tuber. Using visual guides, observation, and a detailed health check worksheet, students will sort tubers into "Plant Me," "Needs Help," or "Compost Bin." They'll gain confidence identifying healthy growing signs—like firmness and visible eyes—and learn how to identify a healthy vs an unhealthy dahlia tuber.
