Tuber Dormancy/Sprouting
Variable; plant in spring when conditions warmTubers are stored or just beginning to sprout eyes in spring
Plant tubers after last frost when soil temperature reaches 60°F. Ensure tubers are firm and have viable eyes. Store unused tubers at 45-50°F in a dark, humid location over winter.
Vegetative Growth
4-6 weeksYoung plants produce multiple stems and foliage, growing 6-12 inches tall
Pinch back the main stem when 6-8 inches tall to encourage bushier, more compact growth and more flower buds. Water consistently and mulch around plants. Apply balanced fertilizer every 3-4 weeks.
Budding
2-3 weeksFlower buds begin to form at branch tips; plants reach 12-18 inches in height
Continue watering and fertilizing. Remove any damaged or diseased leaves. Stake plants if needed for support. Continue deadheading to prevent energy loss.
Flowering
8-12 weeks (summer through fall until frost)Abundant small pompom blooms appear in various colors; continuous flowering
Deadhead spent flowers regularly to promote continuous blooming. Water consistently. Monitor for pests and diseases. Stake stems if they become top-heavy. Apply phosphorus-rich fertilizer to support flower production.
Senescence/Dormancy
Variable based on climateBlooming slows as temperatures drop and frost approaches; foliage yellows and dies back
In cold climates, dig tubers after the first light frost (when foliage blackens). Cut back stems to 2 inches, dry tubers, and store at 45-50°F. In frost-free zones, plants may regrow from tubers.
