Growing Dahlia Vancouver Tubers

Plant these tubers in spring, after the risk of frost has passed. Select a full sun location with fertile, well-drained soil. Plant tubers 2–4 inches deep and space them 18 inches apart to allow proper air circulation and growth. Water deeply at planting and continue watering consistently as plants mature. Staking may be necessary once buds begin to form due to the weight of the large blooms.

Climate and Soil Requirements

Well-suited for USDA dahlia zones 8–10, it can overwinter in the ground in warmer climates. In colder regions, lift and store tubers in a cool, dry space at season’s end. Plant in loose, nutrient-rich soil to support healthy growth and abundant blooms.

Sunlight and Watering

Ensure plants receive 6–8 hours of direct sunlight daily. Keep soil evenly moist but not soggy, and avoid overhead watering to reduce disease risk. A layer of mulch can help maintain soil moisture and suppress weeds.

Care and Maintenance

Deadhead regularly to prolong the blooming season. Fertilize monthly with a balanced, low-nitrogen formula to promote flower production. Support taller stems with stakes if needed as blooms develop.
