Aglaonema Pictum Tricolor prefers temperatures between 65-80°F (18-27°C) and humidity levels between 40-60%. It is important to keep the plant away from drafts or sudden temperature changes as it can damage the leaves. The soil should be kept moist, but not soggy, and it is recommended to use distilled water or rainwater for watering to prevent mineral buildup in the soil. Additionally, the plant can benefit from occasional misting to increase humidity levels.
