Many people know a very beautiful plant called marsh hibiscus. But not everyone knows how you can grow this flower at home and what the optimal conditions for a Chinese rose should be.
This article will tell you about all the intricacies of growing and caring for hibiscus at home, as well as from the article we will learn about how to properly plant in open ground and what breeding method is suitable for this plant.
How to care?
Hibiscus is not too whimsical, but heat-loving plant... It is advisable to keep it at a temperature of 18 to 25 degrees. If the room is hotter than 30 degrees, you should provide the flower with a light shade. In winter, it will grow quietly at 15-16 degrees.
Attention! At a temperature of 10-12 degrees, the plant feels uncomfortable and may begin to shed foliage.
Also, hibiscus needs regular watering. Water should be plentifully, with settled water at room temperature. To avoid waterlogging, make sure the topsoil is dry before watering. Be sure to drain excess water from the pan 20-30 minutes after watering.
The Chinese rose is a light-loving plant, so it is worth taking care of good lighting. This flower loves bright but diffused light. Avoid direct sunlight, which can scorch the delicate leaves and flowers. It will take root best on the west or east side. Daylight hours should last at least 10 hours, if necessary, the plant needs to organize additional lighting.
The shrub must be pruned every year, for the first time pruning should be carried out at a height of about 60 cm. This is done to give it a decorative look, rejuvenate the plant, remove diseased and twisted shoots.
The crown can be formed lush or horizontal... Lush will have to be shaped more often and more carefully. In order for the plant to have such a crown, you should take an area about 1/3 above the leaf facing outward and cut it off.
Pruning is desirable in winter or spring. There are several rules for cutting a flower:
- Prune with regular scissors, as the branches of the hibiscus are too thin for the secateurs.
- It is necessary to cut off the "tops" - shoots parallel to the main branches, as well as all dry and old branches.
- Prune after each flowering to form new shoots.
To prepare the soil yourself, mix turf, leafy soil, humus and sand in a ratio of 4: 3: 1: 1. Chopped charcoal can be added to prevent root diseases. Vermiculite, a special mineral capable of absorbing water weighing up to 500% of its weight, is placed on the bottom of the container, if desired. It protects the plant from fungal diseases and increases air permeability.
The acidity of the soil should be close to neutral: pH 6-7, maximum - 7.8, minimum - 5.5. If the acidity of the soil goes beyond these limits, it becomes more difficult for the plant to take up nutrients. Store soil should be selected carefully, following the acidity guidelines above.
Feed the plant with mineral fertilizers - in winter phosphorus, potash once a month, in summer nitrogen fertilizers - about once every three weeks. Mulch can be applied to protect the hibiscus in winter and reduce weed growth. Mulch consists of several components such as sawdust, tree bark, straw, compost, grass. They also use artificial materials for this, such as paper or cardboard.
Important! Hibiscus does not tolerate excess fertilizer. In his case, it is better to underfeed than overfeed. Otherwise, the plant will stop blooming.
Young shrubs are transplanted annually into larger pots. This is usually done in late April or early May. The flower is transplanted until the diameter of the pot reaches 30 cm.
Adult plants are transplanted every 3-4 years. When replanting, the soil around the rhizome is not removed. The entire earthen lump is transplanted into a new pot with the addition of fresh soil. When the hibiscus becomes too large and cannot be transplanted, the topsoil is replaced annually.
Step-by-step transplant process:
- The plant is carefully removed from the old container.
- The roots are gently freed from excess soil.
- A drainage layer must be placed in the prepared pot, a little soil is poured on top so that after installing the earthen ball, the trunk does not have to be buried or exposed.
- Place the flower in the middle of the pot and sprinkle it with fresh earth around the edges.
For planting seeds or cuttings, a low pot with a height of about 7-10 cm is used. The diameter depends on the number of seedlings. After rooting, each stalk is planted in a separate container up to 10 cm high, with a radius of 4-5 cm.
The material should be chosen carefully. The Chinese rose grows well in ceramic pots and wooden pots. In plastic containers, the roots of the plant will overheat.
If your plant grows outdoors, you should think about how it will cope with the winter. The winter hardiness of the marsh hibiscus is slightly below average. But the root system can often withstand temperatures as low as -30 degrees.
In late autumn, you need to completely cut off the dying shoots, pour the bush abundantly with water and sprinkle it with straw, sawdust or foliage. This will save the plant in case of frost without snow. Also, hibiscus is afraid of winter dampness and often dies from heating.
After the purchase
If you bought a finished flower, then pay attention to the size of the pot. Transplanting is not recommended, but if the pot is small, the Chinese rose should be transplanted into a larger container. After transplanting to a permanent place of residence, the hibiscus is placed in a greenhouse or covered with a plastic bag.
Planting and care in the open field
When planting a plant in open ground, choose a humid and sunny place., fertilize it.
The land around the flower must be constantly loosened, weeds must be removed that interfere with the growth of hibiscus. It is necessary to prepare the Chinese rose for wintering, which was described above. Also, the plant needs to be protected from pests such as aphids and spider mites. To destroy them, it is better to treat the plant with insecticides.
If your plant refuses to bloom and has slowed down its growth, then there is not enough phosphorus or boron in the soil. And if the shoots have slowed down in growth, then there is a lack of nitrogen fertilizers in the soil - the plant should be treated with fertilizer with the addition of nitrogen, and then flowering will surely appear.

Propagation by seeds and cuttings at home
The plant is propagated by seeds as follows:
- Carefully cut the seeds, soak for 12-48 hours.
- Spread out on the ground and lightly press down, cover with glass or foil.
- Every day, the greenhouse needs to be aired a little; when it dries, moisten the soil.
- After emergence, the cover is removed.
- When the leaves develop on the plant, from 3 to 5 pieces, the seedlings dive into separate small pots.
Reproduction by cuttings is different:
- Cuttings are cut from the tops of a young growth with two or three internodes.
- Then they are placed in water or wet sand for 10-14 days.
- After the roots appear, the cuttings are planted in pots.
- A hole is made up to 10 cm deep, a cutting is planted in it.
Attention! When breeding in open ground, you should remember that you need to sow in January-February, choosing for this a fertilized, warm soil and a well-lit place. Also, the seeds can be placed in a growth stimulator for a day, and then planted.
