Vegetative Growth
20-30 daysPlant develops compact bushy form with multiple stems and increasing leaf coverage; no flowers yet.

Flowering
8-12 weeks (extends until frost)Semi-double to double blooms open in succession; colors range from red, orange, pink, yellow, and white depending on variety.
Deadhead spent flowers every 2-3 days to encourage continuous blooming. Water at soil level to keep petals dry. Feed every 2 weeks with balanced fertilizer. Remove diseased leaves promptly.
Late Season & Decline
4-6 weeks until frostFlowering slows as temperatures cool in fall; plant may become leggy or show reduced vigor.
