Dahlia ‘Gillian‘ is a striking cactus variety renowned for its vibrant, golden-yellow blooms and narrow, pointed petals that create a dynamic starburst effect. Growing from tuberous roots (bulbs), this compact plant grows up to 90-120 cm tall and thrives in full sun with well-draining, nutrient-rich soil. It blooms from midsummer through fall, making it a fantastic addition to garden borders and a sturdy choice for cut flower arrangements. [1, 2, 3, 4, 5]
Care & Planting Instructions
- Depth & Spacing: Plant tubers horizontally or pointed down about 8 cm deep, spacing them 15 to 40 cm apart.
- Soil & Sun: Dahlias love heat and direct sun, requiring well-draining soil mixed with compost. Mulch helps retain moisture.
- Watering & Feeding: Water deeply (e.g., every 3 days). Feed the plant with liquid fertilizer every two weeks during the growing season.
- Winter Dormancy: In regions with frost, stop watering in late autumn, lift the tubers once the plant dies back, and store them in a cool, dry place until spring. [1, 2, 3, 4]
