Norfolk Pine
Ah- the Norfolk Pine! The perfect gift for someone who has just moved into their first home around the holidays. The Norfolk Island Pine is also an elegant house plant to welcome into a home for year-round interest!
Also known as Araucaria heterophylla, this plant is not a pine at all. Beautiful and graceful, the Norfolk Pine was originally found on Norfolk Island in the South Pacific, adjacent to Australia. This island is the only natural and known occurrence of the plant. This conifer evergreen tree keeps a symmetrical and compact habit. Due to its branches that present a spiraled and stepped appearance, the tree has a tidy and pyramidal canopy. The needles are fine and almost fern-like, adding a delicate touch. It is so easy to fall in love with this tropical tree! Below you will find care tips for this unique plant.
Moisture:
Norfolk Island Pine’s native habitat is tropical and very humid (50-60%). Our climate is difficult for them, so supply additional humidity through daily misting, a humidifier on a timer, or a humidity tray (set your plant on a tray of water with pebbles). The Norfolk Pine does not like their roots to be waterlogged so make sure you are not over-watering, only watering when the top inch of soil is relatively dry.
Light:
Colorado has very bright light. The Norfolk Pine prefers bright indirect light. Place a Norfolk Pine by a window that receives a good amount of light, but shift the plant away from any direct light, since they are susceptible to sunburn. Many people find that a west or east-facing window is the perfect spot!
Temperature:
Araucaria heterophylla needs a temperature range between 60°F and 70°F. Do not place this tree by a window that transfers cool air inside or a heat vent that could cause scorching or excess drying out of the plant, and its needles. Even slight fluctuations in temperatures can cause stress, so make sure to keep your Norfolk Pine under careful watch. The first sign of stress is needle drop or loss of lower limbs. These lost limbs will not grow back.
Soil:
This beautiful tree would enjoy a well-draining potting mix. The key is moisture retention without becoming waterlogged. Consider a blend of peat moss or finished homemade compost, perlite, and sand. We often also recommend fine-grade orchid bark instead of perlite, since this mimics its native soil.
Fertilizing:
Since Norfolk Island Pines are very susceptible to burning by other means, it should be expected that it’s sensitive to nutrient burn as well. To combat this risk, it is recommended to only fertilize during the growing season (spring and summer, here), and with a diluted half-strength water-soluble fertilizer formulated specifically for house plants. The cadence of fertilizer application is roughly once a month.
Other notables:
The Araucaria heterophylla is sensitive to changes in its environment. Swings in temperature, changes in light intensity, and even moving the plant to different rooms can elicit needle drops. Another thing to note is that this plant is difficult to transplant. We typically recommend delaying transplanting into a larger pot for as long as possible. It is also preferred to up-pot during the growing season. With other houseplants, we usually recommend transplanting into a pot 2 inches larger than the existing pot. For Norfolk Pines, we recommend a pot up to 4 inches larger than its original sized pot. This allows you to reduce the number of up-pots the tree will experience in its lifetime.
While it is hard to keep tropical species like the Norfolk Pine happy in Colorado’s climate, it is well worth it. This tree is festive in the winter months, and a beautiful companion the rest of the year!
