Dahlia 'Wizard of Oz'

Store frost-free and in the dark. Start with a 20-liter pot, plant the tuber 10 cm deep in nutrient-rich soil. Place in a bright, cool spot and move outside after the risk of frost. Pinch out at 20 cm for compact growth.
Plant out after the last frost in 30-40 liter pots with 50 cm spacing. Cover with frost protection cloth on cold nights. Water regularly and fertilize with Zetas dahlia fertilizer. Remove faded flowers and support tall varieties. Overwinter frost-free and in the dark.
