Care Instructions
Transplant Outdoors
Plant tubers outdoors after the last spring frost, when soil temperature has warmed. Space tubers 18 inches apart with 24 inches between rows. In zones 3, 7, treat as an annual and plant in spring. In zones 8, 11, plant in early spring or allow established perennial plants to emerge from overwintered tubers.
Harvesting
Cut flowers in the early morning or evening when blooms are fully open but still firm. Use sharp, clean pruners and take stems at least 12 inches long to maximize the cut flower's vase life. For exhibition purposes, harvest flowers at their absolute peak of fullness. In zones 8, 11 where this dahlia perennializes, dig tubers in fall after the first frost has blackened the foliage, then store in a cool, dry location (50, 60°F) through winter for replanting in spring.
Pruning
As a bush-type dahlia, Arabian Night benefits from early pinching to encourage a fuller, more compact shape and increased flower production. Pinch out the growing tip when the plant reaches 12 inches tall, then again when new growth reaches 12 inches. Remove any dead or diseased stems promptly. Deadhead spent flowers throughout the season to redirect energy into continuous blooming rather than seed production.
