Treelike grevillea with filigree greens
Grevillea is one of the most non-standard maxi-sized indoor plants. Of course, it does not compete in size with palm trees or large vines, but the impression is bright: a "curly" tree, lush and voluminous, very elegant. But at the same time, the grevillea still manages to look very airy, does not burden the room and brings filigree greens and freshness to the atmosphere. She needs a cool wintering; otherwise, taking care of the grevillea is simple.

Tree with fern leaves
Grevillea (Grevillea) Is a small genus of ornamental plants that are actively used in decorative floriculture. Within the natural places of distribution, in Australia, the grevillea are real giants growing up to 35 m in height. In room culture, they are much more restrained and will not exceed 2 m, and often even more compact. At the same time, the height of the plant itself is easily controlled by pruning.
The most widely used species in room culture is also called silk oak. Grevillea large, or powerful (grevillea robusta) - a tree-like herbaceous plant with cirrus leaves, which at first glance cause associations with ferns. Thin cirrus leaves with a filigree cross-section of lobes reach 30 cm in length and are the main pride of grevillea.
The colors of the foliage of this beauty range from forest green to green-bronze or silver, while the growing conditions often change the basic tone to brighter or, conversely, dark. Beauty is only added to him by an attractive gloss: thanks to its luster, the plant always seems radiant and fresh. At room conditions, it will not be possible to enjoy the blooming of grevillea: it can bloom only when grown in open ground.
In addition to large grevillea, you can also find on sale:
- Greville Banks (Grevillea banksii) - a tree-like shrub with pubescent young shoots, more modest, only up to 20 cm in length, twice cirrus-dissected leaves with a reddish fringe of the lower side;
- Grevillea Alpine (Grevillea alpina) - densely branched shrub up to a meter in height with outstretched shoots covered with a beautiful edge and narrow, with a rounded tip leaves up to 2.5 cm in length with a very dark color.
Grevillea growing conditions
A distinctive feature of all grevillea is quite intensive growth. They grow quickly, under comfortable conditions and proper care - rapidly, constantly increasing height, volume, becoming more beautiful. Modest plants in the form of small bushes are quickly transformed into original trees. But the use of this plant in the interior is also very unusual: grevillea is a culture that can be set up only as a soloist, in splendid isolation.
Grevillea is one of the medium-difficult plants to care for. Due to the need to provide conditions of a rest period not typical of living rooms, this beauty is not suitable for everyone. And the care of watering should be scrupulous. But grevillea responds to good care by the amazing beauty of greenery and rapid growth.
Lighting for greville
There is much debate about the proper selection of lighting for an Australian beauty. Due to its natural adaptability and large size, the grevillea adapts well to any light or partially light location. And in many ways, the place at which the greville will be more comfortable to grow depends on the growing conditions of the plant before purchase or propagation.
The standard solution is a bright location with diffuse lighting, but without direct sunlight. But the grevillea will not suffer from both a sunny location and light penumbra. The best choice is to observe the plant under various conditions and stop at the place where the grevillea grows best and does not change the color of the leaves.
Too much shading will cause the leaves to drop. In addition, deviations to a more meager or sunny location lead to a change in the color of the leaves, which may lose the bluish and bronze tints or become faded.
Grevillea is not the most thermophilic plant. She prefers to grow in cool conditions and does not tolerate heat too well, which invariably affects the attractiveness of the leaves. This beauty, even in the warm season, is best kept at a temperature of 10 to 20 degrees Celsius (maximum rates - 23 degrees).
In the cold season, when the grevillea stops growing and is at a dormant stage, it is better for a tree-like beauty to change conditions to even cooler ones. The optimum temperature from November to the end of February is from 5 to 10 degrees, in extreme cases - from 8 to 15 degrees of the body. If the grevillea is kept in typical room conditions in winter or suffers from heat in summer, the plant may lose its leaves (partially or completely).
Choosing the location for the grevillea in your house, immediately draw a circle from the coolest places - the lobby, the landing, the foyer are more suitable for greville than living rooms. But if you do not have such places, choose those locations in which there are no sharp fluctuations in temperature, the climate is the same throughout the year. Grevillea is often grown in cool type greenhouses, in mildly heated winter gardens.
For grevillea, in addition to temperatures, access to fresh air is also of considerable importance. This plant is best grown in often ventilated rooms in which air will not stagnate. Fortunately, gentle grevillea is not too afraid of drafts and it does not need to be additionally protected from air currents.
Thanks to such preferences, greville is able to grow in the warm season not only in the room, but also in the fresh air. Its filigree greenery can decorate balconies, terraces, and relaxation areas in the garden. But moving the grevillea to a new place, be sure to transfer it to a more frequent feeding regimen and choose the right lighting, exposing the pot only within the penumbra and scattered locations.
Watering and humidity
Grevillea - plants are quite hygrophilous. But the rate of moisture consumption from the substrate directly depends on the growth rate of the plant and its age. The older the tree becomes, the more frequent and plentiful watering it needs. Grevillea does not tolerate stagnation of water, but loves the average, not light moisture of the substrate. Between watering, it is necessary to allow drying only the upper prosharka of the earth in the pot, and drain excess water 4-5 minutes after watering.
Drying of the soil should not be allowed not only from spring to autumn, but also in winter. True, in the cold season, watering should be reduced so that the humidity is only mild, less than during the stay of the plant in a warmer environment.
But the main parameter of irrigation for grevillea is water quality. For this plant, you can use only soft water.
It is worth paying attention to air humidity. Grevillea leaves will be more beautifully than the plant will grow in a more humid environment. Grevillea is not afraid of the typical conditions of living rooms, but if you provide it with increased humidity, the attractiveness of the tree will reach a new level.
It is not necessary to install humidifiers for grevillea: this plant is fully content with spraying. But if you have the opportunity to use at least pallets with wet moss, you will save yourself from a lot of trouble. The main thing is to spray regularly, in the warm season - daily.
Grevillea loves top dressing. And this is easy to understand: the rapid growth of greenery requires appropriate compensation for the depletion of nutrient reserves in the soil. If the plant is taken out into the open air, then it needs to be fed weekly. In room mode, from March to early October, dressing should be less frequent - every 2-3 weeks. During a cool wintering, you do not need to feed the grevillea.
For this plant, it is better to use complex, universal fertilizers, rather than mixtures for decorative and deciduous crops. Indeed, despite the fact that the grevillea does not bloom indoors, it does not at all become a purely deciduous crop and for normal development it needs a balance of nutrients, and not just nitrogen.
This Australian beauty tolerates pruning perfectly. Growth restraint, crown thickening can be carried out regularly, annually, before transplantation and the beginning of active growth. Without trimming, pinching or shortening the tops of the shoots, the grevillea is extended, large gaps appear between the leaves.
Transplant and substrate
It is better to transplant a grevillea if necessary, and not according to the schedule. But since the plant grows rapidly, it is usually replaced with a substrate and capacity annually. If you have an old grevillea and you do not transplant it annually, be sure to remove the topsoil and replace it with fresh soil. But during the procedure, be careful not to damage the roots of the plant. It is best to transplant in standard terms, after the start of growth in late February and early March.
The grevillea mix should also be specific. These beauties prefer to grow in clayey texture, but loose, containing a high percentage of humus and certainly acidic substrates.
For grevillea, you should very carefully select containers. This plant is grown in medium-sized pots, because the grevillea does not like too much free soil, developing in such conditions at the expense of the attractiveness of greenery.
Common problems in growing grevillea
- dropping leaves during heavy shading or in hot conditions (especially during wintering);
- stretching the shoots and fading the leaves in poor light, inadequate top dressing or in the absence of clippings.
Diseases and pests
The main threat to all grevillea is spider mites. If the plant does not take measures to increase air humidity, the grevillea grows almost in a dry climate, these pests quickly find comfortable conditions for living and reproduction.
To combat the spider mite, foliage should be inspected regularly, with a frequency of about 1 time per week, and at the first sign of damage, measures should be taken to increase air humidity and spray with insecticides.
New grevillea at home can be obtained from seeds. Their sowing should be carried out in early spring, together with the first garden summers. They are sown in large containers or boxes, in a lightweight universal substrate. They germinate only in warmth, in familiar room temperatures. In this case, the inputs appear unevenly. It is better to dive only after the appearance of the second real leaf, in individual pots.
You can try to get new plants from half-ripened cuttings, which are cut from low shoots, not branched and thin, cutting them together with the “heel” in August. Grevillea cuttings are not rooted in the substrate, but in moist sand. Treatment with growth stimulants is required.
