Provide bright light, keep soil barely moist (not wet), ensure excellent drainage. Avoid overwatering which causes damping off.
Vegetative Growth

Gradually acclimate to outdoor conditions if starting indoors. Maintain dry conditions; water only when soil is dry to touch. No fertilizer needed.
Budding
2-3 weeksFlower buds appear at stem tips, emerging from the center of the compact mound. Buds are initially greenish, gradually showing pink coloration.
Continue minimal watering. Deadhead spent flowers to encourage more blooms. No special feeding required.
Flowering
6-10 weeksAbundant pink-red daisy-like flowers with yellow centers appear in profusion. Blooms are 1-1.5 inches across and attract pollinators.
Deadhead regularly to extend bloom season. Water during prolonged dry spells. Minimal fertilizer; avoid over-feeding which reduces flowers.
Post-Flowering & Dormancy
