Hibiscus is one of the finest plants and is popular in many countries. Often this plant is called the Chinese rose, because it was in this country that the flowers turned out to be cult. Almost all growers decorate their offices and homes with huge hibiscus flowerpots. This plant looks luxurious, blooms for a long time and does not need special care.
The Chinese rose will only feel healthy when it receives enough light, moisture and warmth. If even one component of proper care is missing, then problems with leaves or roots may appear. Pests often appear, which also worsen the condition of the plant. The most common problem in hibiscus is leaf curling.
The main causes and photo of the problem
Deformation of the leaves can be caused by several violations at once. The most common include the presence of pests or diseases, but improper care of a houseplant also plays an important role.
Before starting treatment, it is necessary to find out exactly what caused the curling of the leaves, because each of the existing causes requires an individual approach.
Below you can see what a plant with curled leaves looks like:
Chinese rose is quite resistant to a variety of pests, but before the defeat of a spider mite or aphid, the plant will not always be able to resist. It is necessary to look very carefully at the bottom of the sheets.
- Aphids and ticks live in small colonies, so it is impossible not to notice them.
- The spider mite fully justifies its name, because it braids the damaged areas with a slightly noticeable cobweb. If the curling of the leaves in the hibiscus is caused by these pests, then it is necessary to spray the flower with soapy water. This procedure should be repeated several times.
- If the leaves rapidly curl and fall off, then this indicates the presence of a scale insect. The scabbards are cleaned with an ordinary brush or a rag dipped in an alcohol solution. The alcohol solution can be replaced with a soap solution.

Often the amount of chlorophyll in the leaves of the Chinese rose decreases, so they begin to curl. A disease such as infectious chlorosis is mainly carried by pests. The most common vectors are ticks, aphids and thrips. First of all, it is necessary to get rid of unwanted pests, and then water the plant with a solution of iron chelate and ferrous sulfate.
Hibiscus needs a soil that will be well permeable to air and moisture. For the successful cultivation of such a plant, purchased peat-based soils are not entirely suitable. In this case, the leaves may begin to curl, and the plant will die as a result. It is necessary to add leafy humus, which makes the soil moisture-consuming. The addition of sand or sod land also has an excellent effect on the soil.
In order for the Chinese rose to grow and bloom normally, it needs a lot of copper, iron, magnesium and potassium. If the leaves of the plant began to curl, then this may indicate a lack of trace elements. It is necessary to fertilize the soil with special substances as soon as possible.
Fertilizer for hibiscus growth, which is sold in any flower shop, is quite suitable. In order for the problem to no longer make itself felt, you need to feed the plant once a month.
If the flower is constantly in a room with sufficiently dry air, then this will certainly provoke a rapid curling of the leaves. It is not recommended to allow a low level of moisture in the room. You can put a pallet of wet sand near the potter.
As soon as the sun's rays fall on it, the moisture will begin to evaporate, which will have a positive effect on the growth of the hibiscus. It should be noted that only filtered water should be used to raise the air humidity. It is also recommended to spray the leaves of this plant every few weeks, but only very carefully.
The main enemies of the Chinese rose are direct sunlight. The plant is very fond of light, but from such rays it can get leaf burns, especially if the flower stood in the shade most of the time, and then got into the sun.
Many gardeners recommend paying particular attention to lighting., because not only the problem of leaf rolling depends on it, but also the general condition of the plant. It is necessary to place the hibiscus in a place where there is a lot of light, but not particularly hot. In this case, you should water the plant as often as possible and ventilate the room.
Improper maintenance of hibiscus in a cold room leads to leaf curling. Optimum temperature indicators should not be lower than 18-21 ºC. Hypothermia causes a draft, so you need to choose the right place where the plant will stand.
The curling of the leaves of the Chinese rose is of course a serious problem, but it can be dealt with quite easily.if you know the true cause of its occurrence. Taking the right treatment measures, you can return the plant to its former beauty and health without any problems. The hibiscus will then delight the owner for a very long time with its lush crown and beautiful flowers.
