A beautiful plant that, due to its wide species diversity in the natural environment, can take on a herbaceous form, as well as a shrub or tree, is known as hibiscus.
A deciduous and evergreen mallow species, it grows throughout tropical and subtropical climates. While in temperate latitudes in the open ground, single species are able to grow, united under a single name - garden hibiscus, the care and reproduction of which even a beginner can do.
Garden hibiscus is a rather unpretentious plant of the malvaceous family to care for. Almost all of its species are famous for their very beautiful flowering, you just have to choose the right location and follow all the recommendations for cultivating on the site.
How to care?
Garden hibiscus, depending on the variety, can be very resistant to heat and frost. The older the plant, the more frost resistance it will show. In general, the weather in the middle lane is acceptable for the plant, but in case of abnormal heat, a little shading may be required. For the winter, the bush needs shelter (read more about preparing for the cold and wintering behind a garden hibiscus here).
How to water?
Water for irrigation must be used rain or river, settled, with low hardness. Watering should be moderate as the topsoil dries out. If the weather is hot, watering can be done daily. Leaves need to be washed from dust, thus preventing the appearance of a spider mite. If watering is insufficient, flowers and unopened buds will begin to fall en masse.
Important! To retain moisture in the soil for as long as possible, mulching should be carried out, which will also enrich the soil with nutrients. The best materials are straw and peat with humus.
Hibiscus belongs to sun-loving crops, but it can easily endure an openwork shade, the flowers will be more saturated shades.
To grow hibiscus, you should opt for the sunny and warmest garden area, protected from wind and drafts, which are especially dangerous for the plant in early spring.
With the arrival of spring and the appearance of new stems, old dry twigs must be removed. The pruning procedure is mandatory, since only young branches can bloom. Old branches are cut completely, last year's shoots are shortened by a quarter. With the help of systematic pruning, the plant can be given the desired shape. The procedure has several types:
- Stimulating - carried out in early spring to obtain intensive formation of new shoots.
- Thinning - dried and weakened shoots are removed.
- Corrective - allows you to return a neat appearance to an overgrown plant.
- Autumn - carried out after the cessation of flowering.
- For survival - carried out for diseased plants, leaving a minimum ground mass.
It is very easy to pick up the soil for hibiscus. Any loose, good quality garden soil will do., the main thing is that the risk of moisture stagnation in it is minimal.
Drainage soil with a good level of organic matter and additionally introduced nutrients is all that hibiscus needs to grow comfortably.
During the period of intensive growth, garden hibiscus needs regular feeding, which must include phosphorus and nitrogen. In early autumn, in order to fully prepare the plant for winter, phosphorus-potassium fertilizers must be applied under the bush.
When to replant a tree shrub?
In a sunny place, hibiscus without transplanting can grow up to twenty years. But if the need to move the bush to another place still arises, it is best to do this in early spring, after cutting the shoots half the length and before flowering begins.
In herbaceous hybrid hibiscus, the transplant can be combined with the division of the rhizome.
The transplant is carried out according to the following scheme:
- A pit is being prepared, at the bottom of which drainage is organized from a 15 cm layer of broken red brick. The same layer of sand is poured onto it and a layer of compost, also 15 centimeters high, is laid on top. The compost is sprinkled with the same layer of sand. The result is efficient and nutritious drainage.
- The plant is carefully dug up from the old place.
- The hibiscus is placed in a prepared hole and covered with earth, previously mixed with peat and sand in a ratio of 2: 1: 4.
- The root collar of the hibiscus after transplanting should be slightly covered with earth.
After transplanting, it is necessary to make a watering circle around the plant and moisten the soil. After the water has been absorbed and the earth has settled, you need to add an earthen mixture until it is aligned with the total surface of the flower garden.
Pinching is a gentle pruning technique that involves cutting off the tops of the branches above the topmost node to stimulate growth. The pinch applies to young hibiscusthat do not yet need other, more serious, pruning methods.

Unlike indoor representatives, garden hibiscus is able to withstand low temperatures, is picky about regular loosening of the soil and the removal of weeds growing nearby.
You can propagate garden hibiscus by seeds and cuttings. Both methods have the right to life, but cuttings will allow you to get a flowering bush faster.
- With the seed method of reproduction, an adult ornamental plant can be obtained only after three years.
- For cuttings, you should choose lignified cut shoots that give a panicle of roots in the water. The most viable cuttings can be planted in pots and planted in a permanent place after winter. A strong and mature bush is obtained from a grown and overwintered seedling.

Garden hibiscus is a plant that is resistant to disease.
- If hibiscus is kept in dry conditions for a long time, it can be affected by aphids, thrips, whitefly, and spider mites. If insects are detected on the crop, insecticide treatment is carried out in two stages with an interval of two weeks.
- Due to the poverty of the soil, the plant can get sick with chlorosis.
- If the hibiscus turns yellow, this may be a signal of a lack of iron and nitrogen in the soil or trauma to the root system if the transplant is not carried out correctly.
Hibiscus changed the status of an exclusively indoor plant long ago., having successfully settled in gardens and quickly won the title of one of the most fashionable and luxurious cultures for landscaping.
