Grevillea (Grevillea) – evergreen plant from the protein family. In nature, it can be seen in the shape of a shrub or wood. Culture dwells in Australia. However, some of the 400 species meet in other places, for example, in New Guinea. Plants differ in appearance, although everyone has common features. The highest shrubs grow to 1.5 meters. Trees reach 30-35 meters.
Due to the unusual appearance and high decorativeness, the plant causes interest in many flower water. Therefore, culture is grown at home. In the apartment, the plant is limited to a two-meter height.
Caring for a capricious Australian culture is easy. It is only necessary to provide it with proper conditions for habitat.
Culture is distinguished by smooth cylindrical stems of a grayish shade. Leaves are long, filas, have an elliptical form. Color saturated green. In length they reach 30 cm, located on the stems in large quantities. Due to this, the plant resembles thuy, looks volumetric and attractive. The bottom side of the leaves covers a small pile.
Cystic inflorescences consist of small flowers with long pestles. Their form is quite unusual. The color of petals can be white, but usually they are painted in bright tones (saturated-pink, orange, raspberry). To achieve the appearance of flowers when growing a tree in the room is very difficult.
Plant demanding to climate conditions. But if you observe all the conditions, culture can please the flower in the elegant blooming view.
Best put a plant in a pretty light place without drafts. It is desirable that he will have enough space. Culture loves space and does not tolerate close-based green “neighbors”.
Lighting should be bright. However, it is unacceptable that straight rays of the sun fall on the flower. Especially this concerns the warm period in which the sun is very active. Scattered light can be achieved by light curtains. Grevilleia should be in the light at least 11 hours a day. On cloudy days, you can use additional sources of lighting. FitioMPs are quite suitable.
In the warm season, the village can be moved to the street. It is advisable to put it in place with mild light. The main thing is to watch the culture not bothered a strong wind.
In the spring and summer, the plant feels well at +20.25 degrees Celsius. In autumn and winter months, cooler conditions should be organized – from +7 to +12 degrees. It is easy to achieve this – you can move the culture on the glazed balcony.
To create an imitation of the climate of the Australian forests for the indoor village, you need to provide high humidity. For this, the plant should be regularly sprayed. You can maintain the optimal level of humidity using a domestic steam generator.
If you neglect by this rule, the culture will begin to feel bad, which will affect its appearance. Indoors with dry air (especially during heating) on the leaves of the plant will appear yellow. Then foliage will start to dry out and fall.
It is important to water Grevillei in time, not allowing both moisture stagnation and severe drying. Regular irrigation of culture is held from March to October. These months are worth watching only the top layer of the Earth. The rest of the incoming moisture is needed to reduce. The main thing is that winter soil does not dry completely. For watering should be used by soft water after settling. Suitable and drinking water. The fluid temperature should be room.
For full growth and development of plants at home, a special primer mixture is needed. It is necessary to take conifer, peat and leafy ground, as well as sand (2: 1: 1: 0.5). A good addition will be charcoal and brick crumb.
The soil should be not too sour, nutritious, but light, well to pass the air. Placing the plant in the container, it is important not to forget about the drainage, which is located on the bottom. Ceramzit, pebbles, foam pieces. It will not allow water to be stamped at the roots.
Additional power plant is needed in warm months. Complex fertilizers intended for indoor crops of this type should be applied. You need to make it every 2 weeks. In winter, soil enrichment is not required by minerals.
During the first three years, the procedure should be carried out annually. You can then transplant the plant in 3-4 years. Mature instances do not need this procedure. Instead, change the top of the soil. The procedure is recommended to be carried out at the beginning of spring. Each transplant should be increased in the width of the pot. Capacity with great depths should not be taken, otherwise the culture will slowly develop.
Drainage layer is layered on the bottom of the tank. Then high-quality soil is placed in the pot (the composition is described above). Grevillea carefully remove from the old packaging, shake off the ground. Rotten roots should be trimmed. At the same time, do not forget to process the sections of the Fungicide cuts. The plant is then placed in a new container, sprinkled with soil, slightly press the ground around the stem.
In conclusion, the culture should be poured and leave for 2-3 days to adapt in a privacy.
Grevilleia is growing rapidly. Because of this, she begins to take a lot of space. To form a neat plant with a beautiful and well-kept crown, it is required to trigger the protruding branches in a timely manner. And also such a procedure will be slightly restrained, not allowing the Treet to stretch too.
It is possible to multiply Grevilley in several ways.
Growing culture from seeds – a simple process. Fresh seed material is excellent. When stored, this indicator decreases. You can improve the situation by soaking the seed material in warm clean water or in the composition stimulating growth. The procedure is carried out in February.
- An earthy mixture falls asleep into a small container. This is a composition of sheet, turf, humid and sand (1: 0.5: 0.5: 1).
- Seeds are placed on a depth of 0.5 cm and spray from the sprayer.
- Capacity is closed with polyethylene to create greenhouse conditions. You can use glass.
- Support soft lighting and temperature +18.20 ° C.
- Every day the landing is carried out and as necessary spray.
- When sprouts appear, the observer part is cleaned.
- After the appearance of several sheets, shoots are thinned (the distance between plants about 2 cm should be observed).
As the plant is growing up, the plants are searched into separate small pots.
For this method, semi-respected shoots of about 8 cm. Start the process at the end of August. Slices are desirable to handle growth stimulants. Then put the cuttings in pure sand. Saplings are watered, covered with film or glass tanks (for example, banks). Then they are put in a warm place (at a temperature of + 20 ° C) with mild lighting. Periodically, seedlings are ventilated.
When leaflets appear, young plants can be seeded in separate containers.
Diseases and pests
Culture is resistant to diseases. But with improper care, problems may begin. When the plant is kept in the warm room in winter yellow, and sometimes even fall leaves. With a bad watering and dry air, the ends of the leaves begin to push. When dismissed, root rotes. Therefore, it is important to comply with the conditions of the plant content and watering regime, and also remember the drainage.
If in the room that is inappropriate for the plant, the microclimate, the foliage can attack the cobweb tick. When detecting thin web, yellowing and deformation of foliage should urgently take measures. Need to immediately treat the plant insecticide and adjust air humidity. And also do not forget to periodically examine the green “pet”.
Growing in the open soil
In the garden, the culture is planted at the beginning of autumn. Permissible and spring landing, but in this case it is necessary to often water the plant so that it is rooted. Sunny sections are preferred, easy shadow is possible. If the precipitate falls out in sufficient quantities, the culture almost does not need irrigation. In the arid periods it is necessary to moisten it moderately.
Feed the plant in the garden is not needed. The main thing is to provide a small layer of mulch, which will provide Grevilleigh all the useful substances. In the south, culture can be winter in the garden, but under the condition of its shelter. In other regions, plants for the winter are moved to pots and put in a cool illuminated room, occasionally watering.
Consider a few varieties of the plant.
- Grevillea Benksii (Grevillea Banksii). This is a small tree or shrub. Non-parketer leaves, smooth, dark green, on the reverse side there is a small cannon. Saturated-red flowers, have bend pestles.
- Powerful (Grevillea Robusta). Grevillea Robusta – Big Tree. Often it is called oak silk. In nature, this species reaches 15 meters. Culture has large grayish green leaves with a small fluff. Flowers are characterized by juicy orange. Pestlets “Watch” up.
- Rosmarinifolia Rosmarinifolia (Grevillea Rosmarinifolia). It’s a small shrub whose leaves are reminded by coniferous needles. Beautiful inflorescences include scarlet flowers with white splashes.
- Juniperina (Grevillea Juniperina). This species looks very similar to Juniper. Numerous flowers are decorated with bright red stamens with yellow anthers. Because of this, the plant looks especially “elegant”, reminding fireworks against the background of thick green foliage. Sometimes flowers are yellow or orange.
- Candelabroides (Grevillea CandelaboDes). This is a rather attractive lush shrub. Leaves peristys. Snow white flowers. Large fluffy inflorescences have a cylindrical shape.
