- Improve air circulation: Set the plant in a well-ventilated area or use a fan to prevent future mold growth.
- Adjust watering habits: Water only when the soil is dry to prevent overly moist conditions that encourage mold.
- Maintain clean surroundings: Keep the plant area free of organic debris to avoid mold development.
