Care Guide
Watering
Keep soil consistently moist but not waterlogged; increase frequency during hot, dry spells
Fertilization
Apply balanced diluted organic feed every 4 weeks. Use nitrogen-rich feeds to support lush leaf growth during active cultivation.
Eggshell powder topdress：Crush dried, clean eggshells into a fine powder; sprinkle lightly around the plant base and water in to release calcium slowly into the soil.Pruning
- Deadhead spent flower heads promptly to prevent self-seeding and redirect energy to leaf production.
- Trim back yellowing or damaged leaves regularly to maintain plant health and appearance.
- Cut back the entire plant to the basal rosette after flowering to encourage fresh new leaf growth for the following season.
