Growing Dahlia Creme de Cassis Tubers

Plant these tubers in well-drained soil once the danger of frost has passed and soil temperatures have warmed. Dig a hole 2–4 inches deep and space each tuber 18 inches apart to allow for mature growth. Choose a sunny location for best flowering performance.

Climate and Soil Requirements

Suited for USDA zones 8–10, this dahlia thrives in full sun and enriched, well-drained soils. In zones outside of this range, lift and store the tubers in a cool, dry area before winter to replant in spring.

Sunlight and Watering

Provide full sun exposure (6–8 hours daily) and water regularly during the growing season to keep soil evenly moist but not soggy. Reduce watering after bloom to prepare for dormancy.

Care and Maintenance

Deadhead spent blooms to prolong flowering and encourage new growth. In regions with cold winters, dig up tubers after the first frost, dry thoroughly, and store indoors for the following season.
