Growth Stages

1

Sprouting

2-3 weeks

Shoot emerges from tuber or seedling develops first true leaves

Keep soil warm (60-70°F) and consistently moist. Protect young seedlings from direct intense heat.

2

Vegetative Growth

3-4 weeks

Plant develops stems and compound foliage; bushy growth forms with multiple branching points

Pinch growing tips when 12-15 inches tall to encourage branching and compact form. Stake if needed for support. Feed with balanced fertilizer every 2-3 weeks.

3

Bud Formation

2-3 weeks

Flower buds appear at branch tips; terminal bud clusters develop

Remove lower foliage for air circulation to prevent disease. Disbudding can be done to encourage larger blooms if desired. Continue consistent watering.

4

Flowering

8-10 weeks (until frost)

Full, double pompon flowers in bright yellow open and bloom prolifically

Deadhead spent flowers regularly to encourage continuous blooming. Water at soil level to keep flowers dry. Maintain feeding schedule.

5

Senescence/Frost Dormancy

Until killing frost

Flowers slow production as temperatures drop; foliage blackens at first frost (28-32°F)

In zones 3-9, dig tubers after light frost; in warmer zones, cut back and mulch heavily. Store tubers in cool, dry location (45-50°F) over winter.
