Plant Chinese rose, or Chinese hibiscus (Latin Hibiscus rosa-sinensis) - one of the most popular species in the culture of the genus Hibiscus of the Malvov family. The genus of hibiscus has about two hundred species, but Chinese hibiscus has become the most popular in home floriculture. The Chinese rose flower began its triumphant spread over the subtropical and tropical regions of the Earth, in which it has long and successfully taken root, from the south of China and the north of Indochina. The popularity of this plant is so great that in Malaysia, for example, the Chinese rose hibiscus, called Bungaraya, is one of the country's symbols depicted on coins. In countries where the climate does not allow growing Chinese rose flowers in gardens, they are cultivated as greenhouse or indoor plants.
Indoor Chinese rose (indoor hibiscus) is an evergreen shrub or tree up to three meters high if grown in a greenhouse, and up to two meters in an ordinary home. The leaves of the plant are similar to the leaves of a birch - smooth, shiny, dark green, jagged along the edge, corrugated, elongated-oval. Single flowers are very beautiful: narrow buds, opening, become like wide cups with a diameter of 8 to 14 cm, sometimes simple, sometimes double, depending on the variety, white, yellow, red or pink.
Unfortunately, each flower only blooms for one or two days, but if the care of the Chinese rose is carried out correctly, the flowering process can last from early spring to late autumn.
Sometimes the Chinese rose is grown at home as a standard tree. The Chinese rose is not only an excellent ornamental plant: in places of its natural growth, young shoots of the plant are eaten as a salad, flowers are used to dye hair and food, and dry hibiscus fruits are a component of famous healing teas (Hibiscus, Sudanese rose, Hibiscus tea, etc. etc.).
Growing a Chinese rose from seeds
How to sow seeds
Amateur gardeners are not very fond of resorting to seed reproduction of perennial plants, preferring a more reliable and quick way - vegetative, but the Chinese rose, which can be easily grown from both seeds and cuttings, due to the excellent germination of seeds and the simplicity of the procedure itself makes the seed breeding method is fun and quite productive. It must be said that the seeds of the Chinese rose remain viable for six years.
At the end of February, before sowing, they should be kept in a pink solution of potassium permanganate for disinfection for half an hour, then, after thoroughly washing, soak for a day in a solution of a growth stimulator (Epin, Zircon, Fumara) so that the liquid only slightly covers the seeds, otherwise the lack of oxygen will kill the embryos ... After that, the seeds are germinated in damp gauze, from time to time unrolling for airing.
Heat and moisture - the main conditions for the germination of Chinese rose seeds, so place the damp gauze with the seeds in a perforated plastic bag so that the seeds have access to air. When shoots appear, and this can be expected in three days, they need to be planted in half-liter plastic cups with a mixture of sand, peat and ash: it is very important that the long main root of the plant grows freely, without bending or wriggling. Sprinkle the seeds lightly on top with earth, and then cover the cups with foil or paper.
To prevent seedlings from getting sick with a black leg, they need to be shed with a weak solution of Fundazole and in the future, keep in moderation in watering. For seedlings to grow successfully, they need bright, diffused light, but without direct sunlight.

Caring for a Chinese rose at home
Find a bright spot for the Chinese rose near the window, but protect it from direct sunlight. If you place it in the shade, it may refuse to bloom. In the warm season, it is very desirable to take the plant out into fresh air in a place protected from drafts and the scorching sun. In summer, a comfortable temperature for a Chinese rose is 18-25 ºC and above, in winter - at least 15 ºC, lowering the temperature to 10 ºC can make the plant shed its leaves.
Growing a Chinese rose requires high air humidity, therefore, do not be lazy to spray its leaves in the summer heat and even in winter, if the temperature in the room is higher than necessary for the plant at this time of the year. Sometimes a warm shower is helpful which helps not only to saturate the leaves with moisture, but also to rid the Chinese rose of spider mites, but avoid getting drops on flowers and buds - they can become stained and crumble from this. Use a long-proven method to humidify the air around the plant - a tray with wet pebbles or expanded clay, but so that the bottom of the pot with a Chinese rose does not touch the water.
Caring for a home Chinese rose also provides for a responsible attitude to soil moisture and properly organized fertilization. Watering is carried out with settled water at room temperature, and the frequency is determined by the drying of the upper soil layer 2-3 cm deep. Feed the chinese rose it should only be in the period from April to September once every two weeks with fertilizer for flowering plants or alternate complex mineral fertilizer with organic. In winter, only potassium-phosphorus dressings are introduced in a quarter of the indicated dose, and only if the rose is blooming.
Many novice fans of growing hibiscus at home ask, when to prune a Chinese rose. Pruning is done in the spring before transplanting the plant and before budding on it. The purpose of pruning is to increase the number of flowering shoots, approach the beginning of flowering and form a lush bush.
How to prune a Chinese rose correctly? It is necessary to remove dried, elongated and bare shoots, and cut healthy ones in half. Places of cuts are treated with garden varnish so that juice does not flow out of the wounds. The trimmed parts of the shoots can be used as rooting cuttings.
If your goal is to rejuvenate an adult plant, cut off all the shoots at a height of 15 cm from the base, provided that at least one bud remains in this segment. When young shoots grow, remove the weak ones so that only strong healthy branches remain on the bush. In the summer, do another pruning, and as a result, flower buds will appear on the regrown branches only in early autumn, and you can enjoy the beautiful hibiscus flowers until spring.

Chinese rose in a pot
They choose a pot for a Chinese rose, because in a spacious pot, a Chinese rose will only intensively grow foliage, but will not bloom. Each subsequent pot should be 2-3 cm larger than the previous one in diameter. Young plants are transplanted annually, and those that have reached the age of five - once every 3-4 years. Old, but healthy plants are no longer transplanted, but every year they renew the top layer of the substrate 2-3 cm thick.

How to plant a Chinese rose? First, prepare a mixture of sod, leafy soil (one part at a time), humus earth and sand (half a part), and it is advisable to add another part of peat land to the mixture for young plants. And, of course, a layer of expanded clay, broken brick or clay shards must be placed on the bottom of the pot so that moisture does not stagnate in the roots of the plant. How to transplant a Chinese rose so as not to damage the plant's root system? Of course, by transferring the plant from the old pot to the new one.
Chinese rose after flowering
As such, the Chinese rose does not have a dormant period, in any case, it is pronounced. But if it becomes necessary to give the plant a rest, it is put into a state of dormancy, gradually reducing watering to the required minimum. As soon as the leaves fall off the plant, it is cut off, leaving 15 cm shoots from the root, and placed for the winter in partial shade and cool at a temperature of 10-12 ºC.
From time to time, the Chinese rose is watered, after which the top of the pot is covered with a mat or paper bag to keep moisture in the soil longer. In the spring, the pot with the plant is exposed to bright, diffused light and gradually increase the watering to the usual rate to stimulate the growth of young shoots.

Reproduction of the Chinese rose
As we have already found out, the Chinese rose reproduces well by seeds. How to propagate a Chinese rose vegetatively, for example, by cuttings? It is best to use the cuttings of the Chinese rose left after the spring pruning of the plant for rooting. Treat the sections with a growth stimulant - Kornevin or Heteroauxin - and place the cuttings for growing roots in water or plant in a mixture of sand and peat, covered with a glass jar on top.
Rooting will take place within three to four weeks, after which the cutting is planted in the soil for a Chinese rose and pinched to stimulate tillering. Rooted spring cuttings in good lighting can even bloom in a couple of months. Apical cuttings can also be used for grafting. with two or three internodes, cut in July or August.

Pests and diseases
Of the pests, thrips, aphids and spider mites are dangerous to the Chinese rose, and the invasion of these insects is usually due to your violation of the rules for caring for the plant, and most often the main reason is too dry air. Place the plant on a tray with a wet stone, start spraying the leaves with settled water at room temperature to eliminate the conditions favorable for the life of these insects; twice, with an interval of two weeks, treat the plant with an infusion of hot pepper with soap that destroys insects, and if the infection is too strong, you will have to apply the treatment with Actellik solution in the same mode at the rate of 15 drops per liter of water.
Sometimes growers complain that the leaves of the chinese rose turn yellow... The reason for this may be a disease such as chlorosis, which occurs due to the increased content of calcium and chlorine in the water used for irrigation. The water must be defended and, before watering, add iron chelate to it in the amount indicated in the instructions.

Chinese rose turns yellow
If you irrigate with settled water of the required temperature, but for some reason the leaves of a Chinese rose still turn yellow, the reason for this may be too abundant moisture in the soil for a long time. If there are few yellow leaves, just cut back on watering, you can even replace it temporarily by spraying the leaves. But if the leaves turn yellow massively, you will have to transplant the plant into new soil by examining the root system and removing rotten roots.
Another reason why the Chinese rose turns yellow may be in insufficient light for the normal growth of the plant - in this case, you can observe a real leaf fall. There are other reasons why hibiscus turns yellow.
Chinese rose fall
The leaves of the Chinese rose also fall from drafts and a sharp temperature drop. If you want to preserve the plant, immediately eliminate the deficiencies in the care, because it is not difficult at all. But do not sound the alarm if the plant loses only a few leaves - for a deciduous plant, this is quite normal.
Chinese rose dries
If you water the plant properly and the leaves still dry, this may be the plant's reaction to a change of location. The leaves of the frozen plant also dry out. Give him time to recover and warm up.

Chinese rose wither
This is due to poor watering of the plant. Or it has not yet recovered from the transplant. But worst of all, if the problem is in the roots: carefully clean the roots from the soil, soak for half an hour in a weak solution of potassium permanganate and transplant it into a small pot with light soil (add vermiculite to the usual soil for hibiscus) - maybe these measures will save your plant.
Why does not a rose bloom
There are also several reasons why the Chinese rose does not bloom, but most often this is due to an excess of nitrogen fertilizers in the soil, especially if the plant has a healthy appearance and is abundantly covered with foliage.
The plant also does not bloom:
- when there is not enough light for him;
- if you do not moisturize it enough during the active growing season;
- in case of wintering in a too warm room.
In order for a Chinese rose to bloom, you need to exclude the listed reasons and correct other possible mistakes in plant care.
Chinese rose - signs
The popularity of hibiscus sometimes serves him in disservice: various tales are told about this flower, and often mutually exclusive ones.
For example, some sources claim that the Chinese rose attracts many admirers to the house where the woman lives, while others also persistently warn against the destructive influence of hibiscus on the relationship between spouses and call the Chinese rose "muzhegon".
Some believe that Chinese rose - flower of death, since its untimely flowering predicts the imminent death of a person close to the owners of the plant. And if the leaves of a Chinese rose fall, this is a prognosis for an imminent serious illness of one of the household members.
It is noteworthy that all these negative opinions exist only in our country, and the rest of the world perceives the Chinese rose simply as an attractive and unassuming houseplant.

Chinese hibiscus (Chinese rose): home care
The Chinese rose (or Chinese hibiscus, Latin Hibiscus rosa-sinensis) belongs to the Malvaceae family and is a popular houseplant. An ornamental shrub comes from tropical regions, blooms almost all year round, enchanting with lush and vibrant flowers. If there is enough space, the Chinese rose grows rapidly in height and width and can take on large sizes. In addition to an adequate supply of water and nutrients, the emphasis is on professional pruning. In this article, you will learn how to care for a Chinese rose at home.
Features of caring for hibiscus at home
Hibiscus is an absolutely unpretentious indoor plant. When growing this species, you must follow simple recommendations.
In summer, the air temperature should not exceed +25 degrees. In winter, the Chinese indoor rose can be placed in a colder room. The most acceptable temperature is +15 degrees.
Attention! A strong decrease in temperature will lead to the fall of all foliage.
The rose needs a lot of light and protection from direct sunlight. In insufficient light, the plant is simply not able to bloom. In the warm season, experienced florists are advised to take the flower outside.
It is important to protect the Chinese rose from the harmful draft and the scorching sun.
Watering hibiscus should be carried out only with settled water at room temperature. Before moistening, the soil for this species should dry out well. Improper watering can lead to a complete lack of flowering.
The sprinkling procedure in hot weather should be carried out twice a day. For this, spraying is carried out using a finely dispersed spray gun. In winter, spraying is performed due to the increased dryness of the air.
On a note! A warm shower will help not only wash off unnecessary and harmful dust from the leaf, but also rid the plant of spider mites.
Spraying at home
Home care for a Chinese room rose is to maintain high humidity. Any procedures to increase its level must be performed with the utmost care. No water contact is allowed on buds or flowers. This will lead to the fact that the inflorescences begin to fall off.
You can use a little trick to maintain the required humidity. Any drainage is poured into the pallet under the flower and a small amount of water is poured.
Attention! The water should not touch the bottom of the pot. This can lead to rotting of the root system.
The plant loves a light and nutritious substrate. Recommended composition:
- sheet soil 2 parts
- turf 2 parts
- humus 1 part
- river sand 1 part
- peat 2 parts.
The drainage layer is an indispensable element that will avoid rotting of the root system.
The best time for fertilizing the soil is from April to September. Top dressing for healthy growth is applied 2 times a month. It is better to use special complex preparations intended for indoor plants.
Important! Organic and mineral preparations should be alternated.
Features of winter care, the dormant period of the Chinese rose
It makes sense to take care of hibiscus in winter and feed it only if there are still flowers on it. The introduction of potassium and phosphorus is carried out in much smaller proportions.
New young plants can be obtained from seeds. Only fresh seeds have ideal germination. Sowing is performed at the end of winter after preliminary soaking of the planting material. To learn how to sow adenium flower correctly, you can visit the thematic site with detailed information about succulents. High-quality seeds sprout within a week after sowing.
Adenium obese and other domestic species can be propagated by cuttings. This method is also available for novice florists, as well as obtaining sprouts from seeds. To root the apical shoots, it is necessary to take vermiculite mixed with sand. The cuttings should be provided with good moisture in the sand and air, otherwise the plant will not take root. To obtain cuttings, you can prune adenium in the spring, while forming a bush and obtaining material for growing young plants.
Chinese rose: home care - feeding and watering
Hibiscus need abundant watering during active vegetation and flowering. In autumn and winter, watered moderately, 2-3 days after the topsoil dries up. Chinese roses do not tolerate a lack of moisture and begin to shed their buds and leaves. With waterlogging, root decay and the development of fungal diseases are possible, to which hibiscus is weakly resistant.
The Chinese rose is responsive to fertilizing. They begin to be carried out with the beginning of an active growing season (in March-April). For this, complex fertilizers for flowering indoor plants (Rainbow, Master, Ideal, Terrasol Lux, Pokon, Etisso, etc.) are suitable. Good results are obtained by using the preparation Baikal-EM1. It contains lactic acid, photosynthetic, nitrogen-fixing bacteria, which improve the qualitative composition of the soil and, as a result, the plant immunity increases, the number of buds increases and the flowering period is lengthened. During budding and flowering, hibiscus need an increased dose of phosphorus and potassium, therefore, during this period, the plants should be fed with these fertilizers every 2 weeks.
Important! Fertilizers are applied only after watering the soil, otherwise there will be a chemical burn of the root system!
The easiest way to propagate hibiscus is cuttings that root well even in water. For this purpose, cut off a shoot 8-15 cm long. The lower and largest leaves are removed from it. The cuttings are placed either in water or in moist coarse sand or light sandy soil. The container is covered with a mini greenhouse or polyethylene.
Roots appear in 25-30 days. After another 1-2 weeks, a young rose can be transplanted into a pot for permanent residence.
Signs and superstitions
A tropical plant is simply shrouded in omens and superstitions.
Often they are contradictory, they carry both positive and negative. Thus, Chinese hibiscus is simultaneously called the "flower of love" and "the flower of death." Believe in such extreme options or not is everyone's business. But they are not born out of nowhere, so let's listen to some of them.
Signs associated with the Chinese rose tree:
- It creates the energy of movement around itself, therefore it is suitable for lethargic and apathetic people. A flower that radiates energy, intended for those born under the constellation Leo
- Superstitions differ with regard to the love sphere. Some are inclined to believe that the Sudanese rose strengthens the family union, others say that when a flower appears in the house, the couple will soon part, and the newly formed relationship will quickly collapse.
- A flower that opens its buds ahead of time is a sign of misfortune or the near death of a relative. Plant wilting leads to disease or strife
- When a hibiscus is sick, it drains off the vital energy of its owner, which is weakening every day.
She will accept a lot of superstitions, but most growers are skeptical of them. They just grow a beautiful plant with a lush foliage and rejoice in its flowering.
The photo of Chinese roses once again confirms that their growing popularity is not accidental. A large specimen will decorate an inconspicuous corner of the apartment, decorate it with green foliage and delicate flowers.
Small specimens will find their place among other indoor flowers, will delight you with bright colors, and give a festive, sunny mood. And the abundance of varieties will allow the landlord to create unusual, almost fabulous compositions.
Hibiscus among tropical plants has the largest flowers, for which it is valued by flower growers. Its other important advantage is the possibility of almost arbitrary formation of the crown and the creation of various design elements from it. Unpretentious cultivation and relatively easy care, combined with decorative properties, have made hibiscus one of the most popular indoor plants. The main issue in caring for a plant is maintaining the correct temperature corresponding to a particular stage in its life. Growing hibiscus will definitely bring the desired results if the correct temperature is observed.
