Araucaria (Room Spruce): Care At Home, Reproduction, Species

The genus Araucaria, belonging to the family Araucaria, has about 14 species. It is native to Australia and South America. Araucaria is a coniferous plant that has stiff, needle-like leaves. Its seeds can be consumed as food, while its wood is used to make furniture.

Araucaria species are cultivated as ornamental plants along the Black Sea coast in the Caucasus.

This tree is difficult to grow in low humidity conditions as found in most apartments. It is best grown in a greenhouse. If not cared for properly, it becomes diseased, and sometimes this leads to its death. Araucaria is among those conifers that can be cultivated in room conditions. It is grown as an ornamental-leaved plant, because it rarely blooms at home.

Araucaria is grown in compositions in winter gardens or in pots. Like all other conifers it can purify the air.

Cultivation summary

Araucaria (room spruce): care at home, reproduction, species

  1. Flowering. Araucaria is cultivated as an ornamental deciduous plant, it very rarely blooms in room conditions.
  2. Brightness.

    The tree needs very much bright light, which must be necessarily scattered.

  3. Temperature regime. During the warm season, not more than 20 degrees, and during the winter months, from 10 to 15 degrees.
  4. Watering. During the growing season water abundantly, and during the cold season the substrate is moistened only after it has dried to 2/3 of the depth.

  5. Humidity of the air. It must be high, so the tree is sprayed frequently and regularly with a sprayer.
  6. Fertilizer. During the growing season, fertilize the substrate once every 15 days. For this purpose, take a complex mineral fertilizer with a reduced calcium content.

  7. Dormant period. Starts in late fall and ends with the onset of spring.
  8. Repotting. The procedure is carried out in the spring time or in the first weeks of summer. Young bushes are transplanted only after their roots no longer fit into the container, and older bushes - once every 3 or 4 years.

  9. Mud. It should include peat, sand, leaf and sod soil (1:2:1:2).
  10. Retermination. By cuttings and generative (seed) method.
  11. Pests.

    Mealybugs and aphids.

  12. Diseases. The shrub may become ill due to improper care or unsuitable growing conditions.

Araucaria: description, care and propagation

Home care

Araucaria (room spruce): care at home, reproduction, species


Araucaria is a light loving plant and needs plenty of bright light when cultivated in room conditions. However, it should definitely be protected from direct sunlight.

During the warm season it can be put outdoors if you like, but choose a place where it is well protected from direct sunlight and rainfall.

It is best to put the shrub in a place where it will be exposed to light from both sides. If the light is shining on one side only, the plant needs to be turned 90 degrees once every 7 days for the crown to grow and develop evenly.

Temperature & humidity

House Araucasia is only good in a cool place. Throughout the summer, the temperature should be around 20 degrees.

During the cold season, it should be around 10 degrees, with the room no warmer than 15 degrees.

Water well-drained water is used throughout the year. Make sure that the lump of soil in the pot does not dry out in the summer, as this can cause the plant to suffer severely. In this regard, during the warm season watering should be systematic and abundant, but allow stagnant liquid in the root system should not be allowed. In winter watering should be sparing and infrequent, especially if the shrub is overwintered in the cold.

Air humidity

The plant should be moistened regularly with a sprayer, using well drained water (at least 24 hours) at room temperature. Moisten the foliage all year round, especially if the araucaria is overwintering in a room with a working heating device.


Fertilize once every 15 days during intensive growth with a very mild calcium reduced mineral compound solution. Experienced growers also recommend feeding it with cowpea infusion once every 30 days.

Potting araucaria

Araucaria (room spruce): care at home, reproduction, species

Potting araucaria is done only if necessary after the root system becomes very crowded in the pot.

And this procedure is done in the first half of spring or early summer. Repotting this culture endures rather badly, therefore it is recommended to repot only well-grown bushes.

Potting adult bushes carried out once in 3 or 4 years, for this use a wide pot, which is filled with a mixture of peat, turf and leaf soil, and sand (1:2:1:2). You can also use an earth mixture consisting of sand, humus, peat, coniferous, deciduous and sod soil, which are taken in equal parts. Do not forget to make a layer of drainage at the bottom of the container, which will not allow water stagnation in the substrate.

Araucaria may be grown on hydroponics if desired.

Seeding methods

Growing from seed

Araucaria (room spruce): care at home, reproduction, species

Only fresh seeds of araucaria have good germination, so do not keep them for long. Sow fresh seeds immediately in separate pots filled with a mixture of turf, leaf and peat soil, and sand (1:1:1:1). Or you can use a substrate consisting of sand and peat, in which a very small amount of fine charcoal is added. Water the seeds with a little water, and their surface is covered with a thin layer of sphagnum moss.

Provide systematic airing and moistening from a sprayer, and the air temperature should be about 20 degrees.

Detailed sprouts should not be expected, some seedlings may appear after 15 days, and others - only after a couple of months. After the root system of the young bush becomes very cramped in the pot, transplant it into a new, larger container.


Araucaria (room spruce): care at home, reproduction, species

For the preparation of cuttings, half of the top branches of the bush that have become woody. It is carried out in the first half of spring, with the cut being made a few centimeters below the whorl.

Harvested cuttings are put in a shady place for 24 hours, then the resinous sap is removed from the cut and covered with charcoal powder. To root successfully, the lower part of the cuttings is treated with a product that stimulates root growth. Planted them to rooting in individual pots that are filled with a mixture of peat and sand (1:1) or just sand. On top of the cuttings are covered with a glass jar or a cut plastic bottle. Cuttings are placed in a warm place (about 25 degrees) and systematically aired, as well as moistened with a sprayer.

Cuttings in the heat will take roots after a couple of months, but if the room is cooler, the rooting process may take up to five months.

When rooted cuttings become very crowded in the pot, they will need to be repotted into larger containers, using the same potting soil as for growing an adult araucaria (see above).

Possible problems

Araucaria (room spruce): care at home, reproduction, species

If not cared for properly, the following problems may occur:

  1. Bush growth stopped after pruning. If the upper part of the plant is damaged during pruning, it will not grow properly or will not grow at all. Make sure there is enough bright light, that the room is not too cold in winter and that the humidity is always high.

  2. The bush shrinks and crumbles. If the light is too poor and the humidity too low, the needles will begin to fall off and the stems will wither and turn yellow. If it is too hot in the room or if the substratum regularly has water stagnation, the branches will droop.
  3. Grow very slowly. Araucaria grows and develops very slowly if the soil contains too much calcium.

  4. Very thin branches. Young branches will be too thin if the plant is not fed regularly.
  5. Pests. Aphids and mealybugs, as well as pests of conifers, can harm araucaria.

Araucaria species

Araucaria cooke (Araucaria columnaris)

Araucaria (room spruce): care at home, reproduction, species

In nature the species is found on Pine Island and in the tropical southern New Hebrides.

The short, whorl-assembled branches grow from the trunk at an angle of nearly 90 degrees. The crown tends to widen at the top. The cones are about 10 centimeters long and look bristly because they have a spiky appendage, which extends downward. The needles are soft and the narrowing of the upper part of the crown is very smooth. This species is most commonly cultivated in subtropical and tropical countries.

Araucaria heterophylla

Araucaria (room spruce): care at home, reproduction, species

The plant is native to Norfolk Island, where it can reach a height of about 60 meters. The flaky bark is colored light brown. Because the branches grow perpendicular to the trunk, the crown shape is pyramidal. The square needle-like leaves on the branches are arranged in a spiral, they reach about 20 mm in length and curve slightly upwards. Inexperienced flower growers often confuse this species with the tall araucaria (Araucaria excelsa).

Araucaria angustifolia

Araucaria (room spruce): care at home, reproduction, species

Like the Brazilian araucaria (Araucaria brasiliana). Grows in nature as a species in southern Brazil in its mountainous part. In nature, the tree can reach a height of 50 meters, but in the home - no more than three meters. The slender branches bear linear-lanceolate leaf blades of deep green color, up to 50 mm in length. Its wood is widely used in the construction and furniture industries and for making musical instruments and paper.

Araucaria araucana

Araucaria (room spruce): care at home, reproduction, species

This plant occurs naturally in the western part of Argentina and also in Chile. The trunk can reach a height of up to 60 meters and a diameter of up to one and a half meters. The resinous thick bark is covered with longitudinally arranged cracks. As a rule, the lower branches lie on the surface of the soil and they eventually die off. Lateral branches are gathered into whorls by 6-7 pieces.

In middle-aged plants, such branches grow perpendicular to the trunk, and in old trees, they hang down slightly. Spiny and tough dark green leaf plates on the branches are arranged spirally and very densely. Useful and very tasty seeds can be eaten. The wood is widely used in construction.
