Growing Dahlia Bishop of Llandaff

Plant it after the last frost in spring. Place tubers 2–4 inches deep and space them 18 inches apart in well-drained, fertile soil. Choose a location that receives full sun (at least 6 hours daily). In Zones 8–10, tubers can remain in the ground over winter with proper mulch protection. In colder regions, lift and store tubers in a cool, dry place until spring.

Climate and Soil Requirements

It performs best in USDA Zones 8–10 but can be enjoyed as an annual in Zones 3–7. Use nutrient-rich, well-draining soil to prevent tuber rot and encourage vigorous growth and blooming.

Sunlight and Watering

Provide consistent moisture, especially during hot weather. Water at the base and avoid wetting the foliage. Mulch can help retain moisture and suppress weeds during the growing season.

Care and Maintenance

Deadhead spent flowers regularly to encourage more blooms. Tall stems benefit from staking for support. In cooler zones, dig up tubers after the first frost and store them in a frost-free environment until replanting the following season.
