Botanical description

About 14 species of plants of the genus Araucaria (lat.Araucaria) belongs to the Araukariev family. The homeland of the genus is South America and Australia. Representatives of the genus are conifers with hard needle-shaped leaves.
Araucaria seeds can be eaten and wood is widely used in furniture making. In the Caucasus, off the Black Sea coast, some species are grown as ornamental. Growing araucaria in dry room air will lead to difficulties - this plant is more suitable for growing in greenhouses. If you do not adhere to the rules of care, the plant can get sick or even die.
Not many conifers can be grown at home - araucaria is one of them. Araucaria is an ornamental deciduous plant (since it is almost impossible to achieve flowering when grown in a room), which is grown in pots or in compositions in winter gardens. The araucaria plant is said to purify the air, like its other coniferous relatives.

Briefly about growing

  • Bloom: grown as an ornamental deciduous plant and rarely blooms at home.
  • Lighting: bright light, but shaded from direct sunlight.
  • Temperature: in summer - not higher than 20 ºC, in winter - not lower than 10 and not higher than 15 ºC.
  • Watering: plentiful in summer, in winter - as the earthen coma dries up to 2/3 of the depth.
  • Air humidity: increased. Regular spraying is recommended.
  • Top dressing: during the period of active growth twice a month with a complex fertilizer with a low calcium content.
  • Rest period: from late autumn to spring.
  • Transfer: in spring or early summer: young araucaria - as the pot fills with roots, adults - no more than once every 3-4 years.
  • Substrate: two parts of sod land and sand and one part of leafy land and peat.
  • Reproduction: seeds and cuttings.
  • Pests: aphids and mealybugs.
  • Diseases: all araucaria diseases from poor care and improper maintenance.

Home care for araucaria

Lighting

Despite the fact that indoor araucaria at home prefers bright lighting, it is advisable to hide the plant from direct sunlight. In the summer, it can be taken out into the fresh air in a place protected from rain and sun. The best placement option is for the light to fall on the plant from two sides at once. If the light comes from only one side, the araucaria must be rotated 90 ° C weekly to ensure even growth.

Temperature

Homemade araucaria needs cool content. The optimum temperature in summer is around 20 ° C. In winter, the temperature should be around 10 ° C, but should not rise above 15 ° C.

Watering araucaria

Water araucaria with settled water throughout the year. In the summer, an earthen coma cannot be brought to dryness (it can be a hassle), so watering should be abundant, but care must be taken that excess water does not linger in the pot. In winter they water less, especially if the plant is kept at low temperatures.

Spraying

It is advisable to spray indoor araucaria with water at room temperature (previously, the water must be allowed to stand for at least a day). They are sprayed both in summer and in winter, especially if the plant overwinters in a room with central heating.

Top dressing

In the spring and summer, the araucaria tree is fed twice a month with a very weak solution of fertilizers with a low level of calcium content. It will not be superfluous to fertilize the plant with mullein infusion every four weeks.

Araucaria transplant

If the roots have completely filled the pot, then the plant should be replanted. This is done in early to mid-spring or summer. Homemade araucaria does not tolerate transplanting very well, so it is worth replanting those plants that have grown well. Adult specimens are transplanted every three to four years in a wide pot with a mixture of 2 parts of sand and turf and one part of peat and leaf. Another option is that the substrate is made up in equal parts from humus, sand, peat, deciduous, coniferous and sod land. There must be high-quality drainage at the bottom of the pot, which will not allow excess water to stagnate in the pot. This plant grows very well in hydroponics.

Growing from seeds

Araucaria seeds cannot be stored for a long time, therefore they are sown as soon as they are harvested. They are planted in individual pots. Two substrates are suitable: a mixture of equal parts of sand, leaf, turf and peat soil; another option is sand with peat with a small amount of fine charcoal. The soil is watered a little and covered with a thin layer of sphagnum. The pot needs to be ventilated and sprayed from time to time, and the temperature should be around 20 ° C. Seeds germinate in different ways - some after 2 weeks, others after 2 months. When the roots of a young araucaria completely fill the pot, it is transplanted into a larger pot.

Propagation of araucaria by cuttings

For propagation of araucaria, the upper branches of the plant, which are half woody, are suitable. They are cut a few centimeters below the whorls in early to mid-spring. The cuttings should lie in a shady place for 24 hours, after which the resinous juice is cleaned from the cut on the cutting and powdered with finely crushed charcoal. It will not be superfluous to process the slices with a root formation stimulator. Cuttings are planted in individual containers with sand or with a mixture of equal parts of sand and peat, after which the container with cuttings is covered with a cut plastic bottle or glass jar. Pots of cuttings are regularly ventilated, sprayed and kept at 25 ° C. At this temperature, the cuttings will take root in a couple of months, but if the temperature is lower, it may take up to five months for rooting - you need to be patient. When the cuttings are rooted and the roots completely fill the pot, the young araucaria is transplanted at home into a large pot with soil for an adult araucaria.

Diseases and pests of araucaria

Araucaria does not grow after pruning. If you damage the upper part of the plant, then its further development may be incorrect or stop altogether.

When growing araucaria in an apartment, special attention should be paid to air humidity (should not be dry), lighting (there should be a lot of bright diffused light), temperature (should not be too low in winter).

Araucaria dries and crumbles. The needles fall off, and the shoots dry and turn yellow if the araucaria lacks moisture and light.

Araucaria branches droop from over-watering or too high a temperature.

Araucaria grows slowly. The plant slows down development and growth if there is too much calcium in the substrate.

The branches of the araucaria are thin. Young shoots will be thin if fertilizing araucaria is insufficient.

Araucaria pests. The plant is damaged by both pests of conifers and the usual mealybugs and aphids.

Araucaria

Araucaria is a culture native to South America. It is distinguished by needle-shaped leaves, like those of a spruce. In countries where araucaria grows, its wood is used to make furniture, and the fruits are used in cooking.

This is one of the few conifers of the araucariaceae family that can be grown in a flowerpot at home.

Types of araucaria and their description:

  1. Brazilian araucaria, it is also called narrow-leaved. This plant is found in Brazil and is the main building material. The tree reaches a height of 50 m in forests, but it can also be planted in greenhouses. In this case, the Brazilian araucaria does not grow above 3 m. This culture is also Australian. You can make bonsai from a tree. Araucana chickens are fed with fruits.
  2. Chilean araucaria (Konica spruce). This culture grows not only in Chile, but also in Argentina. The tree in nature reaches a height of 60 m. The trunk can reach 1.5 m in diameter. Thin branches are covered with thorny leaves, which are densely located to each other. The fruits are edible; locals fried or eaten them raw. The most interesting thing is that paper and musical instruments are made of wood. In Europe, the Chilean araucaria was first grown in England, where it grew to the age of 100 years. Chilean araucaria can be found in the botanical gardens of the Crimea and the Caucasus.
  3. Araucaria varifolia (Heterophylla), it is also called room spruce. This tree in the forests reaches a height of 60 m. The branches are at right angles to the trunk. The leaves are needle-like, but soft. Araucaria varifolia forms a lush pyramidal crown. Among the properties of the plant is the ability to purify the air and saturate it with phytoncides.
  4. Araucaria Bidville (North American) is one of the unpretentious species that can be grown in the shade. It is characterized by lush branches with bright green leaves. The tree grows very quickly and becomes spreading. Consider this when planting the Bidville araucaria in your area or at home.


Description of calathea

The vast majority of calathea varieties have underground shoots located near the surface of the earth and forming a root system. They store the moisture necessary for the flower. It is from them that new rosettes appear, formed by large oval leaves. They are up to 40 cm long and are located on long petioles. The calathea bush itself can reach almost a meter in size. The outer surface of the leaves is painted in different shades of green, and may also have splashes of white, yellow or pink. The seamy side of the leaf blades is most often painted in pinkish-purple tones, but there are also species with completely green leaves.

Up to 6 new plates can appear on the bush per year. In the spring, during the flowering period, the plant forms nondescript inflorescences-spikelets of white or lilac flowers, which do not have any special decorative effect. The exception is two calatheas - Varshevich and saffron. Their flowers are located behind bright bracts, painted in tones of white, orange or pinkish colors.

As a representative of Marantovs, calathea also has an interesting feature characteristic of them. The nubs, located between the petiole and the leaf blade, control the leaves themselves, turning them closer to the light. Because of this, every evening the leaf blades of the calathea rise upward, folding like hands in prayer. With the onset of the morning, they return to their original position. Due to this feature, calathea and arrowroot are also known as "prayer flowers".


Home Care Tips

Home araucaria needs special care. The main thing in growing this heat-loving plant is attentiveness and a competent approach.

Adaptation of the tree after purchase is especially difficult. The creation of comfortable conditions for the plant in a new place - temperature, illumination, watering - will help to alleviate the situation. It is advisable to immediately put the tree in the right place and try to touch it less.

If acclimatization is successful, then in the future, indoor spruce will annually give an increase in shoots in the amount of one tier. For their symmetrical growth, it is necessary to systematically rotate the pot so that the luminous flux evenly falls on all sides.

Site selection and temperature conditions

Araucaria prefers abundant lighting and spaciousness, so they choose just such a location. But even in partial shade, she does not suffer much. In the garden, it is recommended to plant a tree under the crowns of tall plants. The house is located away from the scorching sunlight. The optimum temperature for keeping is 22-23 ° C in summer and 16-17 ° C in winter.

Drafts are unacceptable, which leads to drying and falling of the needles. In summer, taking out a room tree to the fresh air is welcomed - a garden or a glazed balcony. In winter, it is advisable to equip artificial lighting with LED lamps and install a humidifier.

It is contraindicated to place pots with araucaria next to heating appliances!

Watering and feeding

The plant should be watered frequently, but without stagnation of water. The mode is selected depending on the intensity of drying of the top layer of the soil: it is impossible for a crust to form. The water is pre-filtered and defended at room conditions. To prevent the needles from drying out, they regularly spray it - preferably twice a day. Araucaria also loves a warm shower. A pallet of damp pebbles or moss can be placed nearby.

Top dressing is applied every 15–20 days. Complex mineral compositions with minimal alkaline inclusions are used, which are diluted in irrigation water. It is recommended to feed the araucaria throughout the growing season - from April to October. It is permissible to feed it with a mullein once a month, which has a positive effect on growth.
