- Stem: Erect, branching stems with a coarse, hairy texture
Care Guide
Watering
Keep soil slightly moist during active growth periods; reduce watering during extended dry spells to encourage drought tolerance
Fertilization
Diluted balanced liquid fertilizer once every 4 weeks to support flowering. Avoid high-nitrogen fertilizers, which can reduce flower production
Eggshell powder topdressing：Crush thoroughly dried eggshells into a fine powder; sprinkle a thin layer on the soil surface around the base of the plant to add calcium without causing nutrient burnPruning
- Deadhead spent flower heads regularly to promote continuous blooming throughout the summer
- Cut back dead, brown stems to ground level in late autumn to tidy the planting area and prepare for new spring growth
- Thin overcrowded seedlings to 30–45 cm apart to improve airflow and reduce competition for water and nutrients
