The Dahlia Cactus ‘Rosella’ produces stunning, bright pink, double-flowered blooms with uniquely narrow, tubular petals. These vibrant plants grow up to 48 inches tall, bloom from mid-summer through fall, and are perfect for cut flowers, landscape beds, and garden borders. [1, 2, 3]
How to Grow and Care for ‘Rosella’ Dahlia Tubers
- Planting Time: Plant in the spring once the soil has warmed up and all threats of frost have completely passed.
- Sun & Soil: Choose a location that receives full sun (at least 6 hours daily) with moist, well-drained soil rich in organic matter.
- Planting Depth: Dig a hole about 4 to 6 inches deep and wide enough to fit the tuber. Lay the tuber flat horizontally with the “eye” (the growing point) facing upward, and cover with about 1 to 2 inches of soil.
- Watering: Water thoroughly after planting. Dahlias have moderate water needs, but avoid waterlogged soil to prevent rotting.
- Support: Since ‘Rosella’ grows quite tall, place a bamboo stake in the hole at planting time to support the plant as it grows. [1, 2, 3, 4, 5]
