Tuber Sprouting & Planting
1-2 weeks until sprouts emergeDahlia tubers begin to sprout eyes in warm soil. Plant after last frost when soil is warm (55°F+), typically mid-May in northern zones.
Ensure tubers are firm and disease-free. Plant in well-prepared, amended soil. Water gently after planting.
Vegetative Growth
3-4 weeksTall shoots emerge and develop into multiple stems with feathery foliage. Plant grows rapidly and can reach 3-4 feet tall.
Pinch out the central stem when plants are 12 inches tall to encourage bushiness and more blooms. Support with stakes or cages early. Remove lower leaves to improve air circulation.
Bud Formation & Budding
2-3 weeksFlower buds begin to form at the branch tips. Cancan White's characteristic white double blooms start to develop.
Remove side buds along the stem for larger exhibition-quality blooms, or leave them for abundant smaller flowers. Feed with balanced or phosphorus-rich fertilizer every 2-3 weeks.
Flowering
8-10 weeks (until first frost, typically October-November)Large, ruffled white double blooms (typically 4-6 inches across) appear and continue prolifically through late summer and fall until frost.
Deadhead spent blooms regularly to encourage continuous flowering. Cut stems early morning for arrangements. Monitor for pests and disease.
Tuber Maturation & Dormancy
Dormancy lasts 4-6 months until spring warmthAfter frost blackens foliage, the dahlia enters dormancy. Underground tubers mature and harden for storage or overwintering.
In cold zones, dig tubers after first frost, brush off soil, cure in a cool dry place for 1-2 weeks, then store at 45-50°F. In zones 8+, leave in ground if soil drains well, or mulch heavily.

Harvest Tips
Cut blooms in early morning when stems are fully hydrated. Cut just above a leaf node to encourage branching. Remove the lowest leaves from cut stems and recut at a 45° angle before placing in water. Blooms typically last 7-10 days in a vase. For maximum longevity, change water every 2-3 days and remove any foliage below the water line. Continue cutting to promote more flowering throughout the season.
