Tuber/Seedling
2-3 weeksTubers show eyes and begin sprouting; seedlings develop first true leaves
Plant tubers after last frost when soil reaches 60°F. Keep soil warm and moist. Harden off seedlings gradually before transplanting.
Vegetative Growth
4-6 weeksRapid stem and leaf development; plant grows 2-4 feet tall with multiple branches forming
Pinch central stem when 12-18 inches tall to encourage bushiness. Support with stakes or cages. Fertilize every 2-3 weeks with balanced or low-nitrogen fertilizer.
Bud Formation
2-3 weeksTerminal buds appear at branch tips; flower buds begin to swell and change color
Remove side buds if larger exhibition blooms desired. Continue staking support. Increase potassium fertilizer slightly.
Flowering
8-12 weeks until frostFull blooms open with characteristic warm sunset colors; multiple flowers per plant
Deadhead spent flowers to encourage more blooms. Cut stems for arrangements in early morning. Keep water consistent.
Post-Harvest/Dormancy
Variable; tuber storage 5-6 monthsFoliage dies back after first frost; tubers are ready for digging and storage
In zones 7-8, dig tubers after frost blackens foliage. Store in cool (50-60°F), dry location in peat moss or sand over winter. In zones 9-10, may overwinter in ground with mulch.
