How to cultivate the splendid azalea

1. Maintenance methods

1. Temperature: Splendid azalea can grow normally in a cool environment without being affected. Because of its strong cold resistance, it can grow in an environment of minus five degrees Celsius in winter. Therefore, because of this property, it can spend the winter outdoors when it is raised in the south. However, it is not suitable for outdoor breeding in the north. The normal growth temperature should be maintained between fifteen and twenty-eight degrees.

2. Watering: The roots of Rhododendron splendidum are very sensitive to water. It will not grow well in soil that is too dry or too wet, so the amount of watering should be controlled during the growth period. In summer, the demand for water is relatively high, so you can water it frequently. After autumn, you should gradually reduce watering, and even more sparingly in winter.

3. Light: Sufficient warm sunlight is required. If it is cultivated in a dark environment for a long time, the number of flowers will be limited. At the same time, strong light also needs to be avoided, especially if the seedlings are exposed to strong light, they will wither.

4. Fertilization: Fertilizer soil is more conducive to growth. However, it does not have too high requirements for fertilizer. During the growth period, you can fertilize it every 20 days. Stop fertilizing during the flowering period and continue to supplement nutrients after flowering.

2. Breeding techniques

1. Reproduction: Cutting and sowing are the main methods of reproduction. Cutting is best done from June to July. Choose branches that are about twelve centimeters long and have about three leaves, and then you can start cuttings. Sowing can be done in April, when the temperature is just right for seed germination.

2. Pruning: Rhododendron needs to be pruned after flowering. While cutting off the withered flowers, some withered branches and leaves at the bottom of the plant should also be cut off. Cleaning up these useless branches and leaves can increase ventilation.

3. Problem diagnosis and treatment

1. Disease: Chlorosis will occur, which will cause the branches and leaves of the plant to turn yellow and lose their luster. It can be improved by fertilizing, or it can be controlled by using some pesticides.

2. Pests: Scale insects may occur, which can be controlled by spraying omethoate solution.
