Tuber Dormancy & Sprouting
2-4 weeksDahlia tuber is planted; eyes begin to swell and sprout roots and shoots after 2-3 weeks in warm soil
Plant after frost danger passes and soil reaches 60°F; keep soil warm and lightly moist; avoid overwatering which causes rot
Vegetative Growth
4-6 weeksShoots emerge and grow rapidly; foliage expands with several sets of leaves and side branches developing; plant reaches 12-24 inches tall
Pinch back main stem when plant reaches 12 inches to encourage bushiness and more lateral flowering shoots; stake or support plant early to prevent breakage
Budding & Flowering
3-4 weeks to first bloom, then ongoingFlower buds form at branch tips; first blooms appear; plant reaches full height of 3-4 feet; buds develop chocolate-burgundy color
Deadhead spent flowers to encourage continuous blooming; maintain consistent watering and fertilize bi-weekly with balanced or bloom-boosting fertilizer; tie or stake plant for support in wind
Peak Blooming
8-12 weeks (mid-summer through fall frost)Plant produces abundant 4-5 inch chocolate-burgundy flowers continuously; peak color saturation achieved; excellent for cutting
Harvest flowers in early morning for longest vase life (7-10 days); continue deadheading; monitor for pests and diseases; water during drought periods; enjoy as cut flowers
Senescence & Dormancy
Variable, through first frostBlooming slows as frost approaches; foliage may yellow or be killed by frost; tubers begin to store energy and harden
After first frost kills foliage, stop watering; cut stems to 3-4 inches above ground; dig tubers carefully and dry in cool place for 1-2 weeks; store in cool (50-60°F), dry location over winter in zones below 8
