The Norfolk Island pine is a popular houseplant. During the holiday season, many individuals turn their plants into living Christmas trees by decorating them with miniature lights, ribbons, and ornaments. The Norfolk Island pine thrives indoors when given good, consistent care. Place the Norfolk Island pine in a brightly lit location near an east, west, or south window. Rotate the plant weekly to prevent the plant from growing toward the light and becoming lopsided. Thoroughly water the Norfolk Island pine when the soil surface becomes dry to the touch. Discard the excess water, which drains frrom the bottom of the pot. From spring to early fall, fertilize the plant with a dilute fertilizer solution every 2 to 4 weeks. Temperatures of 60 to 75°F are suitable for the Norfolk Island pine. Winter is often a difficult time because of low relative humidity levels in most homes. Raise the humidity level around the Norfolk Island pine with a humidifier or by placing the plant on a tray or saucer containing pebbles and water. (Make sure the water level does not reach the bottom of the pot.) Low relative humidity levels, insufficient light, or infrequent watering may induce browning of branch tips and lead to the loss of the lower branches. Norfolk Island pines are rather slow growing. Repotting once every 3 to 4 years is usually sufficient.
