Seedling/Transplant
2-3 weeksSmall plants with 2-4 sets of true leaves, tender and light green
Keep soil consistently moist but not waterlogged. Provide bright indirect light indoors until hardened off. Harden off gradually before transplanting outdoors.
Establishment
3-4 weeksPlant develops stronger root system and fuller foliage. Stems woody at base. 6-12 inches tall.
Water regularly to keep soil moist but well-draining. Stake or support if needed in windy locations. Begin light pruning to encourage branching.
Vegetative Growth
4-6 weeksVigorous stem and leaf development. Plant fills out to mature form. Foliage deep green, becoming woody.
Reduce watering as drought tolerance increases. Fertilize monthly with balanced NPK or flower-specific fertilizer. Prune to shape if desired.
Flowering
12+ weeks (may continue through frost)Abundant flower clusters (umbels) in warm colors—typically orange, red, yellow, or bicolor combinations. Blooms continuously.
Deadheading is optional but encourages more flowers. Water during dry spells. Feed every 4-6 weeks with low-nitrogen fertilizer to favor blooming.
Senescence/Dormancy
Varies by region; 2-4 monthsFlowering slows as temperatures cool. Foliage may yellow and drop in cold climates or tropical dry season.
Reduce watering and feeding. In zones 8-9, prune back in late winter to encourage spring regrowth. In zones 10-11, light pruning maintains shape year-round.
