Tuber Sprouting/Transplant Establishment
2-3 weeksDahlia tubers send up shoots; young transplants develop their first true leaves and establish root systems
Plant after last frost when soil warms to 60°F+. Water gently after planting. Provide stake/support early if windy. Keep soil warm and moist.
Vegetative Growth
3-4 weeksCompact bushy plant develops multiple stems and foliage. Pomponette varieties naturally branch well without pinching but benefit from early pruning
Remove the growing tip when plants are 6-8 inches tall to encourage branching. Apply balanced fertilizer every 2-3 weeks. Keep consistent moisture. Remove any competing shoots.
Bud Formation
1-2 weeksFlower buds appear at branch tips as the plant reaches 12-18 inches height
Begin deadheading any spent blooms. Apply lower-nitrogen, higher-phosphorus fertilizer to encourage blooming. Ensure consistent watering.
Flowering
8-12 weeks or until frostAbundant fully-double scarlet pompom flowers bloom continuously from mid-summer through frost
Deadhead spent flowers regularly to encourage continuous blooming. Water at soil level to prevent mildew. Fertilize every 3 weeks with bloom-booster formula. Stake if flowers get heavy.
Tuber Dormancy/Storage
October-AprilAfter frost kills foliage, tubers enter dormancy and can be dug and stored
In zones 9-10, mulch heavily to overwinter tubers in ground. In cooler zones, dig tubers after first frost, dry for 2 weeks, store in cool (50°F), dark location in peat moss or sawdust until spring.

Garden Color & Borders
OrnamentalThe compact 12-18 inch height and prolific scarlet blooms make Pomponette Scarlet ideal for cottage gardens, borders, containers, and massed plantings. [source]
Harvest Tips
Cut flowers in early morning when fully opened for longest vase life (7-10 days). Cut stems at 45-degree angle, remove lower foliage, and place in cool water immediately. Continuous deadheading of spent blooms extends flowering period significantly.
Fun Facts
- 🌱 Dahlias are native to Mexico and were revered by the Aztecs, who used them for food and religious ceremonies before Spanish conquistadors brought them to Europe in the 16th century.
- 🌱 The Pomponette series was specifically bred to be compact and self-branching, requiring minimal to no pinching—making them perfect for container gardening and urban spaces.
- 🌱 Dahlia tubers can be divided to create multiple plants; each piece must have at least one 'eye' or growth bud to sprout successfully.
