Tuber Dormancy & Sprouting
2-3 weeksDahlia tubers are planted in spring after last frost. Initial growth is underground as shoots develop from the eyes.
Plant in warm soil (60°F+). Water moderately until shoots emerge. Ensure good drainage to prevent rot.
Vegetative Growth
4-6 weeksLeafy, bushy growth with sturdy stems and abundant foliage. Plant develops strong root system and reaches mature height.
Pinch out the top 2 sets of leaves when plant is 12-18 inches tall to encourage branching and more blooms. Stake or support for tall varieties. Fertilize every 3-4 weeks with balanced fertilizer.
Bud Formation
2-3 weeksFlower buds begin to form at stem tips. Plant reaches full height and shows increasing bud development.
Continue staking and tying if needed. Remove lower leaves for air circulation. Switch to lower-nitrogen fertilizer to encourage blooming.
Flowering
8-12 weeks (mid-summer to first frost)Large, full blooms emerge in creamy pale pink tones. Flowers are 8-10 inches across with many layered petals creating full, rounded forms.
Deadhead spent flowers regularly to encourage continuous blooming. Cut flowers for arrangements to stimulate more blooms. Water consistently, especially during hot weather. Monitor for pests and diseases.
Tuber Dormancy Preparation
Until first frost, then 5-6 months dormancyAs temperatures cool and days shorten, flowering slows. Foliage begins to decline after first frost.
Stop fertilizing 4 weeks before first frost. Reduce watering gradually. After first hard frost, cut stems to 2 inches and carefully dig tubers. Store in cool, dry place (40-50°F) over winter.
