Care Guide
Watering
Water deeply when top 10–15 cm of soil is fully dry; reduce frequency during extreme heatwaves
Fertilization
Diluted low-nitrogen liquid feed once every 6 weeks. Avoid high-nitrogen fertilizers to prevent excessive leaf growth that reduces silvery color
Crushed eggshell powder：Sprinkle a thin layer of finely crushed eggshells on soil surface to boost calcium levels; avoid direct contact with stems to prevent tissue burningPruning
- Trim spent flower spikes immediately after blooming to encourage new growth and extend flowering
- Thin overcrowded branches in early spring to improve airflow and reduce pest risk
- Remove dead wood annually to maintain a compact, tidy subshrub form
