Germination
7-14 daysTiny seedlings emerge with cotyledons (seed leaves) visible
Keep soil warm (70-75°F) and consistently moist. Provide bright light immediately after sprouting. Thin seedlings to proper spacing once true leaves develop.
Vegetative Growth
3-4 weeksPlant develops multiple sets of true leaves and a sturdy stem structure
Maintain consistent moisture and warmth. Feed with balanced fertilizer every 2-3 weeks. Pinch terminal buds when 4-6 inches tall to encourage bushier growth with more flower stems.
Budding & Early Flowering
2-3 weeksCharacteristic feathery plumes begin to form at stem tips; color intensifies
Switch to lower-nitrogen, higher-phosphorus fertilizer to promote flowering. Maintain warm temperatures (65-75°F minimum). Remove any early small blooms to encourage larger plume development.
Peak Bloom
6-8 weeksLarge, full red plumes reach maximum size and color intensity; plant is densely flowered
Deadhead spent flowers to encourage continuous blooming. Water regularly during hot periods. Support tall varieties with stakes if needed. Continue fertilizing every 2-3 weeks.
Late Bloom to Decline
Until first frostFlowers continue but may fade slightly; seed heads form if not deadheaded
Leave some flowers unharvested if you want seeds for next year. Reduce watering gradually as temperatures cool in fall. Plant begins to decline with first frost.
