• Humidity: As Peperomia tetraphylla prefers a humid environment, maintaining high air humidity is necessary. This can be achieved by misting, using a humidifier, or placing water trays around the plant.
• Soil: It requires well-draining, loose, and fertile soil. A general indoor plant soil mix can be used, with the addition of perlite or sand to improve drainage.
• Watering: It is not resistant to waterlogging, so watering should be done after the soil surface is dry. During the growing season, the frequency of watering can be increased, but it should be reduced in winter to prevent root rot.
• Fertilization: Balanced liquid fertilizer can be applied once a month during the growing season, but the frequency should be reduced in winter to help the plant rest.
