The Norfolk Island pine (Araucaria heterophylla) is a popular houseplant that is known for its unique pyramidal shape and soft, needle-like leaves. While it is not a true pine, it is a member of the Araucariaceae family, which is native to the Southern Hemisphere. In its natural habitat, the Norfolk Island pine can grow to be over 200 feet tall. However, as a houseplant, it is typically much smaller, reaching a height of 6 to 10 feet.
With proper care, the Norfolk Island pine can make a beautiful and long-lasting addition to your home. Here are some tips on how to care for your Norfolk Island pine:
Norfolk Island pines prefer bright, indirect light. They can tolerate some direct sunlight, but too much can scorch their leaves. If you are growing your Norfolk Island pine indoors, place it near a south- or west-facing window. If you are growing it outdoors, choose a location that receives at least six hours of sunlight per day.
Norfolk Island pines prefer to be kept moist, but not soggy. Water your Norfolk Island pine thoroughly when the top inch of soil feels dry to the touch. Allow the excess water to drain out of the pot, and then empty the saucer underneath the pot. Overwatering can lead to root rot, which can kill your Norfolk Island pine.
Norfolk Island pines are native to a humid climate, so they prefer high humidity. If you live in a dry climate, you can increase the humidity around your Norfolk Island pine by misting it regularly or placing it on a pebble tray filled with water. You can also group your Norfolk Island pine with other plants to create a more humid microclimate.
Norfolk Island pines prefer warm temperatures. They can tolerate temperatures as low as 50°F (10°C), but they will thrive in temperatures between 65°F and 85°F (18°C and 29°C). If you live in a cold climate, you will need to bring your Norfolk Island pine indoors during the winter.
Norfolk Island pines do not need to be fertilized very often. In fact, too much fertilizer can damage their roots. Fertilize your Norfolk Island pine once a month during the spring and summer with a balanced liquid fertilizer.
Norfolk Island pines are slow growers, so they don’t need to be repotted very often. Only repot your Norfolk Island pine when it has outgrown its current pot. To repot your Norfolk Island pine, choose a pot that is one size larger than the current pot. Fill the pot with fresh potting mix and gently place the Norfolk Island pine in the pot. Water the Norfolk Island pine thoroughly and place it in a bright spot.
