Care Guide
Watering
Keep evenly moist but not waterlogged, watering when the top inch of soil feels dry.
Fertilization
Apply a very dilute, balanced fertilizer once as new growth appears.. Alpine plants generally require very little fertilization; over-fertilizing can cause leggy growth.
Eggshell Tea：Crush clean, dry eggshells and steep them in water for 3-4 days. Strain and use the liquid to water the plant. This provides gentle calcium without excess nitrogen, which suits alpine rockery plants. Avoid using raw or unwashed shells to prevent odors.Pruning
- Deadheading: Carefully pinch off spent flowers to maintain a tidy appearance, though as an annual, it will naturally die back.
- Cleanup: Remove any yellowing or dead basal leaves to improve air circulation and prevent rot.
