Below you’ll find the latest 2025 care information, tips for indoor growth, solutions to common problems, and answers to the most searched questions about this popular plant.
What Is a Norfolk Island Pine?
Despite its name, the Norfolk Island pine isn’t a true pine. Its scientific name is Araucaria heterophylla, and it belongs to the ancient Araucariaceae family. In the wild, this tree can grow more than 150 feet tall, with a straight trunk and layered branches that resemble a perfectly shaped holiday tree.
Indoors, it is much smaller and slower-growing, making it a great choice for homes, apartments, offices, and holiday displays. Many people also use the Norfolk Island pine as a Christmas tree due to its festive shape and soft, friendly needles.
Key Features
- Soft, flexible needles
- Symmetrical layered branches
- Slow-growing indoorst
- Works well as an indoor Norfolk Island or gift plant
- Can be trained into a Norfolk bonsai
- Classic holiday appeal when used as a Norfolk Island Christmas tree
Benefits of Growing a Norfolk Island Pine Indoors
Many U.S. households prefer this plant because it adds a natural, calming touch to indoor spaces without requiring complex care. Here are some of the main benefits:
- Evergreen beauty throughout the year
- Suitable for modern, coastal, or minimalist home décor
- Safer than spiky true pines for children and pets (but still mildly toxic if eaten)
- Improves indoor ambiance with its soft, feathery foliage
- Easy to maintain with basic care
- Can last for decades in the right conditions
Light Requirements
Indoor light is the most important factor for keeping your Norfolk Island pine healthy.
Ideal Light Conditions
- Bright, indirect light
- Near a south-facing or east-facing window
- Avoid intense direct sunlight, especially in summer
Although it looks like a tree that would enjoy direct, full sun, its native environment provides bright yet diffused coastal light, too much direct sun can scorch the needles, while too little light can cause the plant to stretch, resulting in weak, uneven growth.
Signs Your Plant Needs More Light
- Sparse branches
- Leaning toward the window
- Needles falling from shaded sides
- Pale or dull green foliage
If your home doesn’t receive strong natural light, you can safely use grow lights to maintain shape and color.
Watering Requirements
Watering the Norfolk Island pine correctly is essential. It doesn’t like to stay soggy, but it doesn’t want to dry out completely either.
Watering Routine
- Keep soil lightly moist
- Water when the top inch feels dry
- Increase watering in summer
- Reduce watering in winter
Overwatering is the most common mistake. The roots are sensitive and can easily develop rot in wet soil.
Signs of Overwatering
- Brown lower branches
- Mushy soil
- Needle drop
- Sour or musty smell from the pot
Signs of Underwatering
- Crispy needle tips
- Branches turning light brown
- Needles falling rapidly
The best approach is consistent, moderate watering rather than heavy or infrequent soaking.
Humidity and Temperature Needs
As a tropical species, the Norfolk Island pine enjoys higher humidity and moderate warmth.
Ideal Conditions
- Temperature between 60°F and 72°F
- Humidity above 50%
- Avoid cold drafts and heating vents
During winter, indoor heating can dry the air, causing needle drop. Using a humidifier or placing the pot on a pebble tray with water can help maintain moisture around the plant.
Soil and Potting
Best Soil Mix
Use a well-draining, slightly acidic soil. A mix designed for indoor trees or houseplants works well, especially if it contains:
- Peat moss
- Perlite
- Pine bark
Pot Requirements
Choose a pot with drainage holes. Repot only when the plant becomes root-bound, usually every two to three years.
Fertilizing a Norfolk Island Pine
It doesn’t require heavy feeding.
Feeding Schedule
- Use a balanced, water-soluble fertilizer
- Feed once every 4–6 weeks during spring and summer
- Avoid fertilizing in winter
Too much fertilizer can damage the plant and cause needle browning.
Pruning and Shaping
It naturally forms a beautiful symmetrical shape, so pruning is minimal.
Pruning Tips
- Only remove dead or brown branches
- Never cut the central leader (the top growing tip)
- Rotate the plant monthly to maintain even growth
Cutting the top will permanently distort the tree’s shape, as it cannot regrow a new central leader.
How Tall Does a Norfolk Island Pine Get Indoors?
One of the most frequent questions from plant owners is about Norfolk Island pine height. Indoors, these trees generally grow:
- 5 to 8 feet tall over many years
- 3 to 6 inches per year on average
Growth rate depends heavily on light, humidity, and overall care. Outdoors in warmer climates like California or Florida, they can grow into full grown Norfolk Island pine trees reaching 80 feet or more.

Growing Norfolk Island Pine Outdoors
In the U.S., this tree can only survive outdoors in warm coastal regions.
Hardiness Zones
It thrives in mild climates like Southern California or parts of Florida. Outside these zones, it should be kept indoors year-round.

Bonsai Care Tips
