Growth Stages

1

Tuber Sprouting

2-3 weeks

Dahlia tuber awakens with visible sprout emerging from the crown; pale white or pink shoot appears

Plant tubers after last frost when soil has warmed to 60°F; keep soil moderately moist; do not overwater to avoid rot; provide warmth (65-75°F optimal)

2

Vegetative Growth

4-6 weeks

Plant develops sturdy stems and bushy foliage; leaves are divided and feathery; multiple side shoots emerge

Pinch the main stem when it reaches 12-15 inches to encourage branching and more blooms; remove lower leaves for air circulation; stake or support tall varieties; feed with balanced fertilizer every 2-3 weeks

3

Bud Formation

2-3 weeks

Flower buds appear at stem tips; small green pointed structures visible where blooms will form

Continue supporting stem growth with stakes or cages; maintain consistent moisture; switch to higher phosphorus/potassium fertilizer to encourage flowering; thin side buds if growing for exhibition blooms

4

Flowering

8-12 weeks (until frost)

Large double blooms unfold with layered petals; for 'Wanda's World', expect dramatic variegated colors; blooms reach 10-12 inches in diameter

Deadhead spent blooms to encourage continuous flowering; harvest blooms in early morning for cut flowers; reduce nitrogen fertilizer; maintain steady watering; provide stakes for heavy blooms; protect from strong winds

5

Dormancy & Tuber Maturation

4-6 months

After first frost, foliage blackens and dies back; tubers underground expand and store energy for next season

In zones 2-7, dig tubers after first frost; clean soil gently and allow to dry in cool location; store in peat moss or sand at 40-50°F; in zones 8-10, cut back foliage and mulch heavily for winter protection
