What are the cultivation methods and precautions of hibiscus flowers?

1. Breeding methods

1. Light: It is a tropical plant and loves light very much. It should be kept in a place with good light and exposed to the sun so that it can bloom and grow better. However, the light in summer is too strong, so you have to avoid it in time, otherwise you may get burned easily.

2. Temperature: Tropical plants have relatively poor cold resistance. Usually, a temperature between 18-25 degrees is most suitable and most conducive to their growth. When the temperature drops in winter, you should take measures to keep warm and avoid frostbite.

3. Soil: It has almost no requirements on the soil and is resistant to poor soil and alkalinity. However, if it is maintained in slightly acidic, fertile and loose soil, it will grow more vigorously and the flowers will be larger and more colorful.

4. Watering: It likes a humid environment, but is afraid of waterlogging. The amount of watering should be controlled. It is better to be less rather than more, and water should not be accumulated. The soil only needs to be slightly moist during the growing season. Avoid the rainy season in time and move it indoors for maintenance, otherwise water accumulation will easily lead to root rot.

2. Precautions

1. Pests: If the environment provided during maintenance is not suitable, it is easy to be infected by pests. Common pests include red spiders, noctuid moths, etc. Spray pesticides as soon as possible after discovery. You can choose dichlorvos or malathion emulsion as the drug. It is also necessary to change the maintenance environment, provide more ventilation, and provide appropriate temperature and humidity.

2. Diseases: In addition to insect pests, it is also susceptible to brown spot disease and leaf blight. After discovery, spray Bordeaux liquid, pick off the diseased leaves and burn them. As long as it is treated in time, it can be treated.
