As a long‑blooming and dependable variety, ‘Thomas Edison’ brings a bold, elegant presence to summer and autumn plantings with minimal fuss.

    Dahlias are generally low-maintenance. They do best in well-draining soil and prefer full sun for optimal growth and flowering. Tubers can be planted outside after the last frost. Nourish with a balanced fertilizer once the plants are established.

    Throughout the growing season, provide regular watering, support for tall varieties, and deadhead spent flowers to encourage more blooms. Harvest blossoms when buds are 3/4 open.
