How to grow Chinese hibiscus so it bursts with blooms? A complete guide to care techniques

People who love growing flowers all like varieties that bloom all year round, and when it comes to blooming all year round, besides roses, Chinese hibiscus is another woody flower variety that is very worth recommending.

Chinese hibiscus is also called zhujin, or zhujin peony, and is an evergreen large shrub in the Malvaceae family. The editor has grown several pots of Chinese hibiscus personally, and feels that Chinese hibiscus is really, really easy to keep alive. Below, the editor of Huinong Network will explain how Chinese hibiscus should be cared for.

I. Growth habits of Chinese hibiscus

To grow a flowering plant well, you first need to understand the growth habits of that variety. Chinese hibiscus is a strongly sun-loving plant, meaning it very much likes sunlight exposure and requires a growing environment with ample sunlight. Chinese hibiscus likes warmth and humidity, is rather afraid of cold, is not cold-tolerant, and is not drought-tolerant either. With suitable temperatures, it can bloom all year round.

II. How to grow Chinese hibiscus

In the process of growing Chinese hibiscus in pots, you should start from the following aspects.

1. Potting soil:

Chinese hibiscus is not strict about soil. To avoid soil compaction caused by repeated watering, when mixing potting soil, try to choose loose, breathable, fertile soil. You can mix garden soil + leaf mold + peat + perlite. When potting, add plenty of base fertilizer.

2. Light:

Chinese hibiscus likes sunlight exposure, so just place it in the spot in your home with the best light.

3. Water and fertilizer management:

After spring warms up, Chinese hibiscus grows vigorously and needs more fertilizer and water. Along with watering, you can apply a liquid fertilizer once every 10-15 days to support its growth. Chinese hibiscus is not very drought-tolerant, and during the growing season the potting soil should stay moist. If the potting soil is too dry, it easily drops flower buds.

4. Pruning:

The branches of Chinese hibiscus grow out very quickly. During cultivation, be sure to promptly remove the growing tips to encourage side branches to sprout. If you do not remove the growing tips, it is very easy to get a single branch that keeps growing without producing branches. Chinese hibiscus blooms in the leaf axils of new branches and flowers open in the morning and fall in the evening, so only when the plant shape is full can many flowers open at once.

5. Winter warmth:

Chinese hibiscus is not cold-tolerant and needs to be kept warm in winter, with the temperature maintained at 12-15°C. When the temperature is below 5°C, the leaves turn yellow and drop. If a relatively high temperature can be maintained in winter, Chinese hibiscus can continue to bloom.

III. Notes on growing Chinese hibiscus

1. Chinese hibiscus is not drought-tolerant. After being subjected to drought, it easily drops buds, so during cultivation the soil should be kept moist.

2. During the care of Chinese hibiscus, the environment should be kept ventilated. Poor ventilation makes it prone to scale insects.

3. During the growing season, pay attention to promptly removing the growing tips to encourage the production of side branches and achieve a full plant shape.

IV. Tips for making Chinese hibiscus burst with blooms

Growing Chinese hibiscus is really very simple. If water and light are controlled well, it will not die, but many flower lovers grow Chinese hibiscus with a thin, sparse plant shape and few flowers. So how can you get a full plant shape?

If you want Chinese hibiscus to burst with blooms, during cultivation you must prune hard. In addition to heavy pruning and shaping before budding in early spring, you should also remove the growing tips at any time during growth to encourage branching.

So you must be ruthless and not be reluctant. When new branches grow 4-6 leaves, pinch off the tips to encourage branching. After several rounds of tip pinching, the plant shape of Chinese hibiscus will become full, and naturally there will be more flowers.

How to grow Chinese hibiscus, and points to note when growing Chinese hibiscus

Chinese hibiscus is a very easy flower to grow. It has the characteristic of blooming on new shoots, so it needs frequent pruning while water and fertilizer keep up; only then can it bloom continuously during the flowering period. Chinese hibiscus likes a warm, humid, sunny environment, is not drought-tolerant, and is not frost-tolerant. North of the Yangtze River it must be grown in pots, and in winter it must be moved indoors to overwinter (if there is heating indoors and the temperature reaches above 15°C, it will continue to bloom).

It can adapt to various soils, but fertile, loose, slightly acidic soil is best. For site selection and land preparation, choose a sunny, warm, humid climate and fertile, loose, well-drained, slightly acidic soil.

The suitable growing temperature for Chinese hibiscus is 15-25°C, and from October to March of the following year it is 13-18°C. The winter temperature must not be lower than 5°C, otherwise the leaves turn yellow and drop. Below 0°C it is prone to freeze damage, but it can still grow normally at high temperatures above 30°C.

After Frost's Descent and before the Start of Winter, it must be moved indoors, because Chinese hibiscus is not frost-tolerant. The overwintering temperature should not be lower than 5°C, to avoid freeze damage; and not higher than 15°C, to avoid affecting dormancy. When the weather is colder, you can cover it with paper or plastic film to keep it warm. Just after moving it indoors, open the windows for ventilation every day during the day, pay attention to changes in the dryness and moisture of the potting soil, and water appropriately. On the coldest days, watering helps prevent freeze damage, but fertilizing should stop.

Chinese hibiscus is a strongly sun-loving plant. During the growing season it needs sufficient light to grow and bloom normally. If light is insufficient, flower buds easily drop, flowers are small, and flower color is dull; but when sunlight is too strong, the plant can suffer sunburn, so it should be properly shaded for protection.

During overwintering, the pot soil only needs to stay slightly moist. Generally, water once every 5-10 days, and the amount of water should not be too much, to avoid root rot caused by a low-temperature, high-humidity soil environment. In northern winters, the climate is dry and phenomena such as pale yellow leaves and dry leaf edges can appear, so pay attention to increasing indoor air humidity. You can spray and wash the branches and leaves or cover with plastic film to increase the air humidity around the plant and create suitable humidity conditions for its growth.

Management is also very important. In early May, when it is moved outdoors to a sunny spot, management work such as increasing fertilizer and water, loosening the soil, and pulling weeds should be strengthened. Apply a dilute liquid fertilizer once every 7-10 days, and when watering pay attention to whether the potting soil is dry or wet, because too dry or too wet will affect blooming. Management after autumn should be cautious, and less fertilizer should be applied later to avoid producing autumn shoots. Autumn shoots are tender, have weak cold resistance, and will suffer freeze damage on cold days.

Every year before moving it outdoors in April, it should be repotted. The soil should preferably be loose, fertile, sandy soil. When repotting, also replace with new growing medium, cut off some of the overly dense, curled fibrous roots, apply plenty of base fertilizer, and add a little phosphate fertilizer at the bottom of the pot.

After moving it outdoors, carry out pruning. For each branch, except for leaving 2-3 buds at the base, cut off all the upper part. Pruning can promote new branches, make growth more vigorous, and also make the plant shape more attractive. After pruning, appropriately restrain water and fertilizer.

After moving indoors in winter, if indoor ventilation is poor and light is insufficient, it is prone to aphids and scale insects, so attention should be paid to improving the ventilation and light conditions of the indoor environment and combining this with chemical control. When there are few scale insects, they can be gently brushed off with a soft brush. The main pests of Chinese hibiscus are aphids, mealybugs, cottony cushion scale, and mites (commonly known as red spider mites). These pests are all piercing-sucking pests. That is, they use their mouthparts to pierce the leaf surface or epidermis of the plant and suck the plant's sap.

First, replace with new growing medium; second, cut off some of the overly dense, curled fibrous roots; third, apply plenty of base fertilizer and add a little phosphate fertilizer at the bottom of the pot.

Chinese hibiscus is a sun-loving tree species. In early May it should be moved outdoors to a sunny spot. This is also the growing season for Chinese hibiscus, so management work such as increasing fertilizer and water, loosening the soil, and pulling weeds should be strengthened.

In early May, move it outdoors to a sunny spot. This is also the growing season for Chinese hibiscus, so management work such as increasing fertilizer and water, loosening the soil, and pulling weeds should be strengthened. Apply a dilute liquid fertilizer once every 7-10 days. Water according to whether the potting soil is dry or wet, because too dry or too wet will affect blooming.

The flowerpot must be sufficiently breathable. When choosing a flowerpot for Chinese hibiscus, choose an unglazed clay pot or wooden barrel pot with sufficiently good breathability. For nutrients, do not apply a single fertilizer only; provide a complete range of nutrients. For light, ideally give it 8 hours of sunbathing every day.

Make Chinese hibiscus bloom more. For potted Chinese hibiscus, it is best to use an unglazed clay pot or wooden barrel (pot). These two kinds of flowerpots have good breathability, making it easy for the Chinese hibiscus root system to breathe and absorb water and fertilizer.

Make Chinese hibiscus bloom more. It is best to use homemade fertilizer alum water for fertilizing, as it is well absorbed and quick to take effect. When using it, be sure to dilute it with water; do not make it too concentrated, to prevent root damage. If you are worried that the fertilizer alum water has an odor, you can put an appropriate amount of vinegar or orange peel into the bucket to reduce the odor.

Make Chinese hibiscus bloom more. In northern households, the reason for failure in growing Chinese hibiscus is mostly freezing to death because it did not overwinter safely. Chinese hibiscus is a southern tropical summer flower, likes sunlight, and is not cold-tolerant. The northern climate is cold, and home flower growing has no conditions for building a greenhouse, so whether Chinese hibiscus can overwinter safely is the key.

Make Chinese hibiscus bloom more. After spring begins, the temperature gradually rises and Chinese hibiscus starts to sprout. To make Chinese hibiscus bloom continuously in summer, you must pay attention to pruning its branches and promptly removing buds.

What are the ways to grow potted Chinese hibiscus?

Chinese hibiscus was already a popular ornamental plant in ancient times, and its place of origin is China. Below, the editor has compiled methods for growing potted Chinese hibiscus, hoping it will be helpful to everyone.

How to grow potted Chinese hibiscus?

Methods for growing potted Chinese hibiscus 1. Soil selection: choose loose, breathable soil mixed from furnace ash and peat soil, then add some decomposed chicken manure as base fertilizer. Never apply fertilizer that has not been fully decomposed, such as sesame paste residue, bean cake, bone fragments, and so on, as it easily damages new roots. Mix garden soil, cake fertilizer, and sand in a 5:1:4 ratio; mix garden soil, sandy soil, and dried manure in a 4:2:4 ratio; mix garden soil, sandy loam or furnace ash, and decomposed organic fertilizer in a 3:2:2 ratio.

Methods for growing potted Chinese hibiscus 2. Light requirements: Chinese hibiscus likes a sunny, warm, humid, and ventilated environment. During its growing season it should be given sufficient light to grow and bloom normally. Generally, light should be no less than 8 hours per day. If light is insufficient, phenomena such as bud drop, smaller flowers, and dull flower color easily appear. But Chinese hibiscus dislikes muggy weather. If sunlight is too strong, Chinese hibiscus can also be sunburned, so especially in summer, try to avoid direct sunlight. You can provide appropriate shading around midday, or spray water on the leaves and surroundings, but if the sunlight is not too hot, you do not need to shade it.

Methods for growing potted Chinese hibiscus 3. Temperature requirements: Chinese hibiscus is not cold-tolerant. The most suitable growing temperature is 15°C-25°C. From March to October the temperature can be 18°C-25°C, and from October to March of the following year the temperature can be controlled at 13°C-18°C. But the winter temperature must not be lower than 5°C, otherwise the leaves turn yellow and drop. If the temperature reaches below 0°C, freeze damage will occur. Chinese hibiscus is heat-tolerant and can still grow normally at high temperatures above 30°C.

Methods for growing potted Chinese hibiscus 4. Fertilizing method: The principle for fertilizing Chinese hibiscus is to apply thin fertilizer frequently. If too much fertilizer is applied, it will also cause only branches and leaves to grow excessively without blooming. After May in spring is an important period of vegetative growth for Chinese hibiscus. At this time the plant needs a large amount of nutrients because of rapid growth, so a nitrogen-phosphorus-potassium compound fertilizer can be applied about once every 20 days. From June, the plant blooms one after another until October. During this period, a phosphorus-based fertilizer can be applied once a month to keep the flowers blooming continuously. During the flowering period, heavy fertilizer should not be applied, to avoid bud drop. From October, fertilization should be controlled. You can sprinkle a thin layer of dry fertilizer on the surface of the potting soil, such as coarse cake powder or sauce residue powder granules.

Methods for growing potted Chinese hibiscus 5. Watering method: Chinese hibiscus is tolerant of moisture and afraid of drying out, and is afraid of waterlogging and rainlogging. In daily care, keep the potting soil moist. During the growing season, keep the potting soil moist so the stems and leaves can grow quickly; if the water supply is insufficient, the leaves easily wilt, turn yellow, and drop, so it is best to water once a day. During the dog days, water once in the morning and once in the afternoon. At the same time, water should also be sprayed on the leaves and around the potting soil to increase air humidity. Note that during the rainy season, accumulated water in the pot should be drained promptly.

Methods for growing potted Chinese hibiscus 6. Pest and disease control: The main pests of Chinese hibiscus are aphids, mealybugs, cottony cushion scale, and mites (commonly known as red spider mites). After aphids and mites occur, insecticides such as yamansha, yamanjing, and Manchongqing can be diluted to a certain multiple and sprayed on the leaves to kill them, once a week; generally 2-3 times can basically eliminate them. Mealybugs and cottony cushion scale can harm leaves and epidermis. Generally, imidacloprid-type drugs or their improved formulations can be diluted to a certain multiple and sprayed on the affected parts to kill them. If the damage is severe, it can be applied once every 10 days, and 3 times can basically eliminate them.
