Hibiscus, also known as Chinese rose or big red flower, is a common ornamental plant that is loved by people for its bright flowers and long blooming period. To make hibiscus bloom continuously, some basic care points need to be mastered.
### Light and Temperature
Hibiscus enjoys plenty of sunlight and requires at least 6 hours of direct sunlight per day. Insufficient light will affect the growth of the plant and fade the color of the flowers. In terms of temperature, hibiscus is adaptable, but the most suitable growth temperature is between 18-28 degrees Celsius. During the hot summer, pay attention to shading and ventilation to prevent the leaves from getting sunburned; in the cold winter, keep warm to prevent frostbite.
### Watering and Drainage
Hibiscus prefers a moist environment, but its roots do not tolerate waterlogging. During the growing season, keep the soil moist but avoid积水. It's best to water in the morning to avoid leaving water droplets on the leaves at night, reducing the occurrence of diseases and pests. Also, ensure that the bottom of the pot has drainage holes so that excess water can be drained out.
### Fertilization
Hibiscus enjoys fertilizer. During the growing season, apply a balanced compound fertilizer once a month to promote plant growth and blooming. During the blooming period, you can increase the proportion of phosphorus and potassium fertilizers to extend the blooming period and improve the quality of the flowers. When fertilizing, follow the principle of "frequent application of thin fertilizer" to avoid excessive fertilization, which can lead to excessive plant growth and affect blooming.
### Pruning and Shaping
Hibiscus grows quickly and requires regular pruning and shaping. After the blooming period, promptly remove the残花 and枯枝 to promote the growth of new branches. At the same time, pruning can be used to adjust the shape of the plant, making it more beautiful. When pruning, be careful not to remove too many branches to avoid affecting plant growth.
### Disease and Pest Control
Hibiscus is prone to attacks by pests such as aphids and red spiders, and is also susceptible to diseases such as leaf spot and root rot. During the care process, regularly inspect the plant and deal with diseases and pests promptly. Biological or chemical methods can be used for control, but attention should be paid to dosage and safety.
### Propagation
Hibiscus can be propagated by cutting or grafting. For cutting, select healthy branches, cut 10-15 cm long cuttings, insert them into moist soil, keep them moist, and they can take root in about 1 month. For grafting, select healthy rootstock and scion, perform the grafting, and pay attention to management after grafting.
### Soil Selection
Hibiscus is not strict about soil requirements but prefers well-drained, fertile soil. A mixture of leaf mold, garden soil, and sand can be used to ensure soil ventilation and water retention.
### Environmental Adaptability
Hibiscus has strong adaptability to the environment and can grow in various conditions. However, to ensure the health of the plant and the blooming of the flowers, it's best to choose an environment with plenty of light and good ventilation.
In summary, to make hibiscus bloom continuously, it is necessary to manage aspects such as light, temperature, watering, fertilizing, pruning, and disease and pest control. As long as these care tasks are done well, hibiscus can grow robustly and bloom beautiful flowers.
