An east-facing window is a good spot to grow anthuriums. They should be placed close to the window. When grown too far away from the window, the leaves tend to stretch, giving the plant a leggy look. Normal room temperature is ideal for anthuriums. They do best with constant temperatures, but they can tolerate temperatures as low as 55 degrees for short periods of time.
Anthuriums grow actively from early spring through fall.
During that time, water often enough to keep the potting soil moist at all times. During their winter rest period, allow the top inch or so of soil to dry between waterings. Fertilize anthuriums while they are actively growing. Use a water-soluble fertilizer at half strength at every other watering. Since anthuriums are tropical plants, they prefer increased humidity.
