The Dahlia Cactus ‘Carousel’ is a striking perennial prized for its fully double, spiky flowers, which typically feature bi-color petals that curl and twist outward. Reaching a mature height of roughly 80 to 90 cm, it blooms profusely from mid-summer through to the first fall frost. [1, 2, 3, 4, 5]
How to Grow & Care
- Planting: Plant the tuber (bulb) in the spring after the risk of frost has passed, with the “eye” or sprout pointing upward, about 10 to 15 cm deep. Space multiple tubers 40 to 60 cm apart. [1, 2, 3, 4, 5]
- Sunlight: Prefers full sun (at least 6 to 8 hours of direct sunlight daily) for the best stem strength and bloom production. [1]
- Soil & Water: Thrives in fertile, well-draining soil. Water deeply once or twice a week, but avoid waterlogged conditions to prevent tuber rot. [1]
- Winter Care: Dahlias are not frost-hardy (USDA Zones 8–10). In colder climates, carefully dig up the tubers in the fall and store them in a cool, dry place over the winter.
