Care Guide
Watering
Keep substrate slightly moist but not waterlogged; allow top 1–2 cm to dry between waterings
Fertilization
Diluted weak liquid feed once every 2 months. Use low-nitrogen, balanced feed to avoid overstimulating soft growth
Eggshell powder topdress：Grind clean, dried eggshells to fine powder; sprinkle thinly on soil surface to boost calcium content without burning delicate rootsPruning
- Trim brown, desiccated stems to maintain a tidy mat appearance
- Remove spent strobili to redirect energy to new vegetative growth
- Gently divide overcrowded clumps in spring for propagation
