Growing Blackberry Ripple Dahlias

Plant dahlia tubers in spring after danger of frost has passed. Choose a sunny, well-drained location and plant each tuber 2 to 4 inches deep and 18 inches apart. Water regularly, allowing the soil to dry slightly between watering. Pinching back early growth promotes bushier plants and more blooms. Support taller stems with stakes as needed.

Climate and Soil Requirements

Perennial in USDA zones 8–10. In colder zones, lift tubers after the first frost, dry them, and store in a cool, dry place for replanting in spring. Requires loose, fertile, well-drained soil for optimal growth.

Sunlight and Watering

Thrives in full sun with at least 6–8 hours of light daily. Water deeply to encourage strong root development but avoid overly wet conditions that can cause rot.

Care and Maintenance

Deadhead regularly to promote continuous flowering. Feed with a balanced fertilizer during the growing season and reduce watering as temperatures cool in the fall. Store lifted tubers in peat moss or sawdust for winter preservation in cooler zones.
