Seedling (germination to first true leaves)
7-14 daysTiny green seedlings emerge with cotyledons. True leaves appear ovate and slightly textured.
Keep soil consistently moist but not waterlogged. Provide bright light. Maintain 70-75°F for best germination. Thin seedlings to prevent damping off.
Vegetative growth (first true leaves to branching)
3-4 weeksPlant develops 4-8 true leaves and establishes a sturdy root system. Main stem strengthens and lateral branches begin forming.
Reduce watering frequency slightly. Apply balanced fertilizer at half strength weekly. Pinch central stem when 4-6 inches tall to promote bushier growth.
Branching & bud formation
2-3 weeksPlant becomes increasingly bushy with multiple lateral branches. First flower buds appear at branch tips.
Maintain even moisture. Switch to bloom-promoting fertilizer (lower nitrogen, higher phosphorus and potassium). Ensure full sun exposure.
Flowering & peak bloom
8-12 weeks or until first frostAbundant coral-orange semi-double to double flowers bloom continuously. Plant remains compact and tidy, typically 12-18 inches tall.
Deadheading not required but light pruning encourages more blooms. Water consistently in heat. Apply balanced fertilizer every 2-3 weeks. This stage lasts until frost.
Senescence (end of season)
Variable; until killing frostFlowers diminish in size and frequency as temperatures drop and days shorten. Plant weakens after first frost.
Allow flowers to develop seeds if self-seeding is desired. Remove plant once severely damaged by frost. Collect seed heads before plants fully decompose.
