Care Requirements
1. Light

💡 Tip:
- Peace lilies may droop when thirsty but recover quickly after watering—making them an easy “indicator plant” for soil moisture.
I can also make a care schedule chart for Spathiphyllum wallisii showing watering, light, and fertilization for each month—very handy for beginners.
