Growth Stages

1

Transplant Establishment

2-3 weeks

Young plants with 4-6 leaves, establishing root systems; compact growth

Keep soil consistently moist; pinch tips when plants reach 6 inches tall to encourage bushiness; provide stakes if needed

2

Vegetative Growth

4-6 weeks

Rapid stem and leaf development; plant becomes full and compact; no visible buds yet

Continue pinching tips until mid-July to promote branching and fuller plant; maintain consistent watering; apply balanced fertilizer every 2-3 weeks

3

Bud Formation

2-3 weeks

Small flower buds appear at branch tips; plant reaches full size; foliage becomes denser

Stop pinching; reduce nitrogen fertilizer; maintain even moisture; avoid overhead watering to prevent fungal issues

4

Flowering

6-8 weeks

Coral-pink double or semi-double blooms open progressively; full plant is covered in flowers; peak color display

Deadhead spent flowers to encourage more blooms; reduce watering slightly; stake tall varieties; maintain air circulation

Late Bloom & Senescence

3-4 weeks until frost

Flowers begin to fade; some petals brown; plant slows growth as temperatures drop
