Dahlia Cactus 'Preference' (Ships in Spring)

Dahlia

Dahlia 'Preference' is a semi-cactus variety with soft peachy-pink blooms that fade to cream at the tips, creating a luminous effect when caught in the light. The flowers, typically 4 to 6 inches across, have elegantly elongated petals that add texture to floral arrangements. This dahlia reaches a height of four to five feet, standing tall and sturdy even in rain. Blooming from July until frost, it thrives in full sun with consistent moisture and well-drained soil. Ideal for cutting gardens, borders, and mixed plantings, it pairs beautifully with deep purples, yellows, and other late-season perennials. Hardy in USDA zones 8 to 11.

Growing and Maintenance Tips for Dahlia Cactus 'Preference' (Ships in Spring)

Planting: In spring, plant tubers 3 to 4 inches deep with the eye facing up, once soil has warmed to at least 60°F. Space 18 to 24 inches apart to accommodate their vigorous growth and airflow needs.
Location: Full sun (6–8 hours daily) is essential for strong stems and abundant blooms.
Soil: Fertile, well-drained soil with a slightly acidic to neutral pH (6.0–7.0). Enrich with compost before planting.
Watering: Water deeply once or twice a week, keeping soil evenly moist but not soggy. Avoid watering until shoots emerge to prevent rot.
Temperature: Hardy in USDA zones 8–10. In colder zones, lift tubers after frost and store in a cool, dry place.
Fertilization: Apply a balanced fertilizer monthly or use a slow-release formula at planting and midsummer. Avoid high-nitrogen feeds.
Pruning: Pinch back when plants reach 12 inches tall to encourage bushier growth. Deadhead regularly to promote continuous bloom.
Pest & Disease: Watch for aphids, spider mites, and fungal issues. Ensure good air circulation and avoid overhead watering.
Propagation: Divide tubers in spring, ensuring each division has at least one viable eye.
