The Chinese rose, or Chinese hibiscus, is an evergreen shrub from the mallow family, which can reach a height of three meters. The crown is dark green, the flowers are large, up to 16 cm in diameter. Thanks to breeders, there are about 300 varieties of the plant. Some varieties may have white, cream or red spots on the dark green leaves.
Hibiscus is very popular and can be easily propagated at home. But what if the plant does not take root? Let us analyze in the article the secrets of plant propagation in different ways and caring for indoor hibiscus.
What time of year should indoor hibiscus propagate?
If you propagate the plant by seeds, then it is better to sow them in February-March.... Propagation by cuttings is possible year-round, but most favorably in January-February.
Next, you can see a photo of indoor hibiscus.
A clay or plastic pot with a diameter of up to 9 cm is chosen for hibiscus, preferably light, since the roots overheat in a dark pot. You can choose a pot with an insert, if you delay watering for several hours, then a tray with accumulated water will save the plant from drying out. Before planting, the pot should be washed with laundry soap and boiled over.
You can buy the soil for a Chinese rose ready-made, or prepare the soil yourself, for this you need to know what mixture to make. For the preparation of the soil is used:
- 2 parts of turf soil;
- 1 part deciduous soil;
- 1 part of vermicompost or humus;
- 1 part coarse sand.
This potting mix is suitable both for the first planting of the plant and for the annual repotting. Hibiscus is unpretentious, so you can deviate a little from the soil standards by slightly changing it. For example, add a little peat, vermiculite.
Important! The soil for hibiscus should be nutritious, very loose, and the acidity should be close to neutral.
How does it propagate by seeds?
Growing a Chinese rose from seeds is very exciting, and due to its good germination, it is productive. This process can be called not reproduction, but selection, since the exact same plant is not obtained from seeds.
Seeds can be bought, or you can collect yourself:
- Pollination. By noon, when the anthers on the stamens open, the pistils must be pollinated with bright yellow pollen.
- The flower withers and falls off over time, but you should not pull it off by force.
- After successful pollination, the capsule inside the sepals begins to grow and remains green.
- The seeds ripen for about 2 months, and when the box turns yellow, a gauze cap is put on it, which "catches" the fallen seeds.
Hibiscus seeds remain viable for six years.
Seed propagation instructions:
- Before sowing, the seeds are kept for half an hour in a pink solution of potassium permanganate, thoroughly washed, and soaked for a day in a solution of a growth stimulator. The liquid should only slightly cover the seeds so that the embryos do not die from lack of oxygen.
- Seeds germinate in damp gauze in a warm place, the first shoots can be expected in three days.
- Then they sit down in pots or plastic cups with soil, lightly sprinkle with earth and cover with a film.

Cuttings: how to root cuttings?
To propagate a Chinese rose by grafting, you can use the material left over after pruning the bushes. How to take a scion correctly? A young, not stiff stalk 8-12 cm long, with at least three internodes, is selected, preferably cut in January-February. There are two types of planting - into the water and directly into the ground.
Instructions for planting a cutting of a Chinese rose in water:
- A vessel, preferably made of dark glass, is filled with water.
- A stalk is placed in it.
- Top, to increase humidity, is covered with a cap, glass jar or plastic container.
- The cuttings take root in a month.
- After the roots appear, the plant is transplanted into the ground.
Reference! For a young plant, the addition of sphagnum moss to the soil is very useful.
Instructions for planting a Chinese rose directly into the ground:
- Half of the leaves are removed from the cutting.
- A pot with a volume of 0.5 liters is prepared - it is washed and doused with boiling water.
- Before planting, the soil is spilled with boiling water.
- Drainage is laid at the bottom, the pot is filled with loose, water and air-permeable soil.
- The stalk is buried 1.5-2 cm into wet soil.
- Top covered with a jar or put on a package (conditions for a mini-greenhouse are created).
- The pot with the plant is placed in a bright place with a temperature of 23-25 degrees, but not in direct sunlight, and is not rearranged from place to place.
- If condensation occurs - ventilation.
- The stalk begins to grow - an increase in airing time, if the hibiscus does not lower its leaves - remove the greenhouse.
Reproduction of hibiscus by cuttings retains varietal characteristics, and the plant blooms in the first year.

Is it possible to plant the offshoot in open ground?
The Chinese rose is a thermophilic plant and is not suitable for our climate.... With the exception of garden hibiscus, adapted for temperatures down to -30 degrees. The place for the plant is chosen bright and protected from the wind. The soil must be light and nutritious, water must penetrate deeply.
Planting is carried out in the spring when the soil warms up well. Pit preparation:
- The planting hole should be twice as deep as the hibiscus root system.
- A 15 cm thick drainage layer made of broken bricks is laid.
- The next layer is 10 cm thick from sand.
- Compost layer 15 cm.
- The last layer is sandy, 15 cm deep.
A nutritious soil is compiled for planting:
- 2 pieces of soil from the pit;
- 4 parts of peat;
- 1 part sand.
A seedling is placed in the prepared hole so that the neck is slightly covered, and it is covered with prepared soil.
Further home care
The plant is watered abundantly, the earth is poured and neatly leveled. The main rule in caring for hibiscus is regular watering and loosening of the soil. In early summer, when new shoots appear, it is necessary to cut off the old and dried stems. If the planting was carried out during the active growing season, then the hibiscus must be fertilized with dressings with a high content of nitrogen and phosphorus, and if in the fall, then potash fertilizers. During the hot summer months, the Chinese rose is watered daily.
What if the plant does not take root?
If the plant does not take root, then:
- There is a lot of lime or chlorine in the water for irrigation. It must be boiled and defended.
- Hibiscus loses leaves from drafts, hypothermia, or heavy watering.
- The plant withers - poor watering may be the culprit.
- If the Chinese rose dries even with proper watering, then this may be a reaction to a change of place. The plant must be given time to recover.
- Buds appear that fall off without opening - the soil dries up from insufficient watering, the plant lacks nutrients, or the temperature is low in the room.
- If the lower leaves fall, and the new ones grow yellow, the reason is that there is a lot of calcium and chlorine in the soil, but not enough iron and nitrogen, dry air and watering with cold water.
- On the leaves there are pinkish spots that are not provided for by the variety - the plant does not have enough light or there is an excess of fertilizers.
The Chinese rose is a perennial plant, and with proper care from small seeds or seedlings, a beautiful, abundantly flowering plant will soon develop, which will delight for many years and become an excellent design solution for the home.
