With its unique appearance and symmetrical branches, the Araucaria has become a popular indoor plant, especially as a Christmas option. But to thrive, it requires proper care. Here's everything you need to know.
10 Tips for Success with your Araucaria
1. Light – More than you think
The Araucaria loves light. Place it near a south or west-facing window where it gets several hours of direct sunlight each day. Many people believe that it can do well in the shade, but that is a myth. Araucaria really needs good light to grow and survive.
Just protect it from the strongest midday sun in the summer, but otherwise direct sun is fine. Don't be afraid to put it right by the window.
Important to know: Araucaria is sensitive to changes in its environment. If you move it, the needles may start to fall off due to stress. Try to find a good spot and leave it there.
2. Temperature
Araucaria thrives best in temperatures between 18 and 24 degrees. It is important to avoid sudden temperature changes and drafts. Do not place it too close to a drafty window or front door, especially in winter when the cold can get in.
Since Araucaria comes from warmer climates, it does not like cold at all. In winter, it is especially important to keep it away from cold air currents.
3. Humidity
The indoor Araucaria plants requires high humidity to thrive. When the air is too dry, the tips of the branches can turn brown and dry. This is especially common in winter when the elements are running at full blast.
Increase humidity by:
- Shower the room fir regularly
- Using a humidifier
- Group plants together
4. Watering
Always feel the soil before watering. Stick your finger about 2.5 cm into the soil. If it feels dry, it's time to water.
Good trick: Lift the pot. If it feels light compared to when you last watered, it's time to water again.
When you do water, do it thoroughly. Water until it runs out of the drainage holes in the bottom. This ensures that the entire root ball is moist. But be careful not to overwater as Araucaria is sensitive to this and can get root rot.
In winter, when the plant is dormant, water less frequently. Let the soil dry out a bit between waterings.
5. Fertilization
Fertilize your potted Araucaria approximately every fourth watering during the growing season (spring and summer). In the fall and winter, you can reduce to every sixth watering. Use a fertilizer made for houseplants.
Tip: Water lightly before fertilizing. This will prevent the roots from being burned by the fertilizer when the soil is too dry.
6. Soil & Transplanting
Araucaria only needs to be repotted when it becomes root-bound or when the roots start to grow out of the drainage holes. They don't grow very quickly, so repotting every two years may be enough.
The best time to repot is in the spring when the plant is entering its active growth phase. Choose a pot that is just a little larger than the current one as Araucaria actually thrives in a cramped space.
Use a well-drained potting soil that provides good aeration to the roots. Araucaria prefers slightly acidic to neutral soil with a pH between 6.0 and 7.0. Our peat-free soil is well suited for indoor firs.
7. Pot
Always choose a pot with drainage holes. This will prevent water from pooling at the roots, which can lead to rot. The pot should be large enough to accommodate the growth but not too spacious.
8. Pruning – Carefully and infrequently
Cut away dead or yellow branches to encourage healthy growth and maintain shape. But be careful not to cut too much at once. Araucaria does not recover quickly from heavy pruning.
Most often, it is enough to simply remove dead parts and let the plant grow naturally.
9. Pests & disease
Araucaria can be affected by spider mites and scale insects. If you spot pests, treat immediately with insecticidal soap or neem oil.
Regular inspections will help you catch problems early. Take extra care to look at the branches and undersides of the needles.

10. Winter rest
During the winter, the indoor fir tree slows down its growth naturally. Reduce watering and stop fertilizing during this period. Protect the plant from cold drafts as it is sensitive to low temperatures.
It is completely normal for growth to stop in the winter. Give it some rest and it will come back stronger in the spring.
Propagation of Araucaria
Propagating Araucaria is not easy, but it is possible! The best way is to use seeds from the cones.
Here's how:
- Remove the seeds from the cones and clean off all cone material.
- Soak the seeds in warm water for 24 hours to soften the shell.
- Use well-drained potting soil in small pots or seed trays
- Place the seeds on the surface of the soil and press them down lightly, do not bury them deeply
- Cover with plastic or a clear lid to create a mini greenhouse
- Keep the soil evenly moist but not wet
- It may take several weeks or even months for the seeds to germinate.
- When the plants are large enough to handle, replant them in their own pots.
It is also possible to propagate through cuttings, but it is more difficult and not always successful.
Common Problems with Araucaria
Brown tips on branches The most common problem is brown, dry tips. This is almost always due to too low humidity. Increase the humidity with a humidifier or by showering the plant more often.
Needles falling off: If the needles start to fall, it may be due to:
- Too little light
- Too much or too little water
- Sudden environmental changes
- Drafts or temperature changes
Yellow branches: Yellowing branches can be caused by:
- Natural aging of lower branches (normal)
- Too little light
- Nutritional deficiency (fertilize more regularly)
Pests & Diseases
The room fir is generally quite hardy but can be affected by:
Spider mites: Small mites that cause silvery spots. Treat with predatory mites or soap.
Scale: Small brown scales on the branches. Remove by hand or use alcohol in a spray bottle.
Aphids: Small green or black insects. Spray away or use beneficial insects against aphids.
Powdery mildew: White powdery coating. Improve air circulation and reduce humidity slightly.

Is Araucaria Poisonous?
Araucaria is not particularly toxic to pets or children. However, the needles are sharp and prickly, which can cause skin irritation or injury if touched. There is also a risk of choking if small children put needles in their mouths.
Although Araucaria is not directly poisonous, it is, as always, good to be careful and keep an eye on small children and pets around the plant.
