The Dahlia Border – “Graz” is a vibrant, low-growing tuberous dahlia variety that produces striking orange-red blossoms. Reaching a mature height of 30-60 cm, it is compact enough for front garden borders, walkways, and patio containers. [1, 2, 3]
Key Growing Requirements:
- Planting: Plant tubers about 8 cm deep, spaced 15–40 cm apart. The tubers should face downwards when placed in the soil.
- Soil & Sunlight: Requires well-draining, nutrient-rich soil and full sun. Adding sand or compost helps if your soil is clay-heavy.
- Watering: Needs deep watering every 3-4 days. If you reside in a winter-rainfall region, halt watering completely by May to prevent the bulb from rotting.
- Care: Use liquid fertilizer every 2 weeks for optimal blooming. Regularly remove spent flowers to promote new growth.
- Winter Dormancy: In frosty climates, dig up the tubers in the fall and store them in dry peat moss in a cool, dark place until spring. [1, 2, 3, 4]
