Norfolk Island Pine care: Tips for growing araucaria indoors
Araucaria heterophylla is commonly known as the Norfolk Island Pine. It is an odd but captivating plant rather than a common pine. This plant is often cultivated as a landscaping tree in typical subtropical areas of North America and attains a remarkable height of up to 2400 inches. This plant is also popular indoors, known as the Norfolk Island Pine, with a height of up to 24 to 96 inches.
Norfolk Island Pine can be easily identified through its tall, straight trunk and regular branch structure. It is abundantly dense with short and stout needles directed inward, which is why many people are fond of placing plants indoors for beautifying purposes. Because it is a slow-growing plant, it is commonly sold as a live Christmas tree. Many people like to play with this plant, decorating it with ribbons and ornaments on Christmas. However, most people get rid of it as soon as the holidays are over.
Whether kept indoors or outdoors, Norfolk Island Pines thrive in environments with plenty of light. For those who want to maintain a healthy and thriving plant, providing ample sunlight is essential to its growth. Growcycle has an enhanced variety of gardening accessories and tools, such as grow lights and pots, allowing Norfolk Island Pines to thrive even indoors.
History
The Norfolk Island Pine is a tree from the Araucariaceae family that is native to Norfolk Island, a small Pacific island. When Captain James Cook discovered the island in 1774, he noticed the tall, straight trees and thought they could be used for ship masts. However, the wood was too brittle for that purpose, but it was still used locally for building. Due to its broad popularity in the region, the plant is also known as the Australian pine.
Today, the Norfolk Island Pine is popular worldwide as an ornamental tree, especially in coastal areas, and as an indoor plant. It’s easy to care for and is often used as a living Christmas tree. On Norfolk Island, the tree is a national symbol and even appears on the island's flag. Although it’s not endangered, efforts are made to protect the natural populations on the island to ensure this ancient tree continues to thrive.
Essential Care Tips to Thrive Araucaria
Caring for a Norfolk Island Pine is relatively simple. It has a few basic needs that can be easily met. Below are the main care requirements to ensure the plant thrives.
Light
Norfolk Island Pines are sun-loving plants that thrive in full sunlight. They should be put in an open area with enough of sunshine whenever feasible. They are, nevertheless, quite adaptable and can withstand inadequate lighting for extended periods of time, even months. This feature allows them to be kept inside during winter and then taken outside in a sunny place once it's summer.
When a plant grows straight tall and does not fill in much, it is often a sign that it is not getting enough light to thrive. This stretchy or leggy aspect of the plant usually results from low light combined with too much fertilizer application. Under these conditions, it is generally better to suspend fertilizers until the plants are healthier and more sunlight will be plentiful.
Soil
Norfolk Island Pines usually do best when planted in rich, sandy soil with some degree of acidity. These tree plants do not do well in alkaline soils since the ideal soil pH level lies somewhere between 4.5 and 5.5. By keeping the soil well-drained and replenishing the soil nutrients, the establishment and healthy growth of the plant will be quite easy.
With a simple soil test kit, one can ensure that the Norfolk Island Pine has the correct amount of acidity by testing the soil periodically. At intervals when the soil pH is within the range considered acceptable for the plant’s active growth, chances are high that long-term health for the tree will be attained.
Water
Norfolk Island Pines need regular watering to stay healthy. Watering after a week or two is more than sufficient while growing indoors. Watering should also be adequate so that surplus water drains from the pot's bottom. This ensures the roots are properly moistened.
Placing a Norfolk Island Pine outdoors may require careful watering. The soil might not retain enough moisture, so growers must water it, especially during dry seasons. However, be cautious not to overwater, as constantly wet soil can lead to root diseases.
Temperature and Humidity
Norfolk Island Pines can grow in warm and moist conditions with a temperature range between 65 and 70° F. This approach allows people to keep the plants indoors, where they can thrive and stay healthy. While the plants can handle brief periods of low and high temperatures, exposure to temperatures below 35° F can cause severe damage or even kill them. That's why avoiding taking them outside during cold weather is important.
Humidity is another key factor in Norfolk Island Pine care. Since these plants naturally grow in moist environments, indoor air can become quite dry, especially in winter. To keep the air around the plant humid, gardeners can use a humidifier, which helps prevent the leaves from drying out or turning brown. Another option is to mist the plant occasionally or place a small tray of water nearby to increase the humidity level.
Fertilizer
When growing a Norfolk Island Pine tree, feeding it frequently is very critical. In the growing season, applying a diluted liquid fertilizer is advisable. A balanced 20-20-20 NPK (Nitrogen, Phosphorus, and Potassium) formulation works well. Still, one can also choose fertilizers specifically designed for conifers or azaleas to provide the extra acidity that Norfolk Island Pines prefer.
Fertilizing should be done throughout the active growing season, but it's a good idea to pause during low-light periods, such as in winter when the plant's growth slows down. This helps to avoid excessive fertilization, which can be damaging to the plant.
Types of Norfolk Island Pine
Here’s some key information about the different types of Norfolk Island Pines that is important for their care:
Main Variety
Only one main variety of Norfolk Island pines is available in the market: Araucaria heterophylla. This is the most used plant, both indoors and outdoors. Unlike many other plants, the Norfolk Island Pine lacks named ornamental cultivars or varieties.
Other Species
Occasionally, people might come across other species from the same family, like A. columnaris, A. araucana, or A. bidwillii, which are sometimes mislabeled as Norfolk Island Pines. Though these species are less common, their care needs are similar to those of Araucaria heterophylla. If people have one of these varieties, they can follow the same care guidelines to keep it healthy.
Techniques for Growing Araucaria Fast
Following are some useful techniques that will help to grow Norfolk Island Pine fast:
Pruning
Pruning is critical to Norfolk Island Pine handling but should be carefully executed. For indoor cultivation, it is normal for the lower branches to die gradually. These branches should be cut to preserve the plant's cosmetic value and possibly its health. Nevertheless, cutting off the top portion of the tree is usually discouraged.
If the tree has grown so much that it has outgrown its space and become too big for its pot, the main growing tip on the top of the tree can be removed. This will allow the tree to develop from that part but be warned that it will change how the plant appears in its classic solid green shape.
For outdoor Norfolk Island Pines, routine pruning is unnecessary beyond removing dead or diseased branches. This helps keep the tree healthy and free from potential problems. Regular maintenance will ensure the tree remains in good condition without requiring frequent interventions.
Potting and Repotting
Proper potting and repotting are essential to keeping a Norfolk Island pine healthy. The plant should be repotted when it gets root-bound, which occurs when roots begin to grow out of the drainage holes or when it outgrows its pot. Repotting every two years is usually enough for younger, slower-growing Norfolk Island Pines. However, as the plant matures and its growth speeds up, more frequent repotting may be necessary.
Spring is the best time to repot Norfolk Island Pine. When choosing a new pot, pick one that is only a few inches larger than the current pot to avoid excess soil, which can hinder growth. Also, make sure the new pot has plenty of drainage holes at the bottom.
For larger Norfolk Island Pines, use a pot heavy enough to keep the plant stable. Gardeners can also secure the plant by incorporating some potting sand or similar heavy materials into the combination. Similarly, Norfolk Island Pines do well in a potting mix composed of peat, sand, and other ingredients to give it slight acidity. This kind of mix is healthy for the plant as it supplies the right amount of moisture and provides good drainage.
Growing from Seed
The best way to grow Norfolk Island Pine is through seeds:
First, the seeds must be sown on a fully moist germination medium, such as a peaty and sandy mixture. Do not bury the seeds in the soil. Instead, use a spray bottle to mist the top surface or place a plastic cover over the seeds to prevent moisture loss and germination stimulation.
The seeds should be exposed to bright, indirect light for optimal growth. If propagating outside, choose a location with partial sun and only three to four hours of direct sunlight daily. As the seeds begin to germinate, one will notice the development of a tap root and top growth.
Use enough moisture to keep the germination medium moist at all times, but don't make it too wet and soggy. Maintaining optimum moisture levels is very important for the healthy development of the seedlings. The seeds will form strong and healthy Norfolk Island pine seedlings, given proper light, moisture, and temperature.
Benefits of Norfolk Island Pine
The Norfolk Island Pine provides several noteworthy benefits. It adds a touch of elegance to any space and offers practical advantages that enhance its environment.
Space Saving
The Norfolk Island Pine is a great choice if growers have limited space. This plant grows upward instead of spreading out, making it perfect for small apartments or even tight office desks. It takes advantage of vertical space, adding a touch of green without taking up much room.
Stress Relieving
Having a Norfolk Island Pine in the room can also reduce stress levels. This plant serves more than just aesthetics as it helps build an atmosphere that can help one concentrate better and be more productive. It integrates well in someone’s house or office and helps to uplift the mood more naturally.
Pest & Disease Management
Various pests and plant diseases can attack Norfolk Island Pines. Some of the pests are mites, mealybugs, whiteflies, soft scales, and aphids. It is imperative to spot and deal with these infestations early. Regarding pest troubles, always choose the least toxic measures to avoid harming the plant and the environment.
Norfolk Island Pines, however, are not only pest-prone plants but also sick plants. Excessive watering is the main cause of plant fungal diseases. One such disease is anthracnose, whereby brown spots appear on the foliage or other parts of the plant, which may lead to the plant's death in the long run.
To avoid these issues, do not expose the base of the plant to excess moisture for long periods and provide good air circulation to it. Keeping a strict schedule of examining the plant for defects and fixing them in time will save the Norfolk Island Pine from such ailments and enhance its growth.
Common Problems and Solutions
Here are some key issues to be aware of to ensure proper care for Norfolk Island Pine:
Brown Needles
Brown needles on a Norfolk Island Pine often signal environmental stress. They generally denote adverse environmental conditions. This tree does not tolerate cold and very hot temperatures very well. Temperature changes can cause the needles to change color to brown. Moreover, brown needles may be a result of problems related to irrigation. Too much or too little moisture may cause this failure. By controlling the temperature and moisture, these complications may be avoided.
Yellow Needles
The factor that causes the yellowing of the needle leaves largely depends on the exposure regions. The tree might not be getting adequate sunlight, or it might be getting too much light with no breaks in between. Large temperature differences are significant factors behind the yellow coloration of the leaf needles. This problem can be solved by changing the light intensity and temperature.
Needles Dropping
If the tree drops needles, it may be due to overwatering or insufficient light. Overwatering leads to root problems, which can cause needle drop, while inadequate light can stress the plant and lead to needle loss. Ensuring proper watering practices and adequate light conditions will help prevent needle drop.
