Breeding methods and precautions for summer azalea

illumination

Summer azaleas should not be grown in direct sunlight, especially in summer. Even the evening sun rays must be blocked. It is best to place the summer azalea in a semi-shaded place, where there is both shade and a certain amount of sunlight.

soil

Summer azalea prefers slightly acidic soil, and alkaline soil can easily cause it to wither and die. The soil must have good air permeability and drainage. Loose and fertile soil is especially suitable for the growth of summer azalea. Leaf mold contains a high level of humus. This soil is rich in nutrients and is very suitable for cultivating summer azalea. Humus can effectively improve the soil, reduce harmful substances, and promote the root growth of summer azalea.

Watering

When cultivating summer azalea, you should pay attention to controlling the amount of watering. Excessive or too little watering is not conducive to the growth of summer azalea. If it is too dry, the branches and leaves of the summer azalea will turn yellow or even wither, and the flowers will become dull in color. Excessive watering will easily cause the flowers to wither prematurely. When watering during the flowering period, be careful not to get the flowers wet, and also protect the summer plants from rain at normal times.

The principle of watering is to water thoroughly when the soil is dry, and water in the morning and evening. The water used can be natural rainwater without chemicals. It is best to use acidified water to maintain the acidity of the soil. Do not use tap water for watering for a long time.

temperature

Summer azalea is very afraid of cold, so it needs to be transplanted indoors in winter. The temperature should be above 8℃. In summer, when the temperature is high, it needs to be shaded to prevent the leaves from being sunburned.

Pest control

Summer azalea has weak resistance and is very susceptible to disease and insect infestation. Diseases and pests will greatly affect the growth and development of the plant and flower buds. If this continues for many years, the summer azalea will grow poorly and gradually wither. In order to prevent this from happening, sterilization and pest control must be carried out several times a month.

General insect pests can be controlled with ordinary pesticides, but it should be noted that if chlorosis occurs, various trace elements in the soil should be added in time. You can directly change the pot and soil, or you can spray diluted ferrous sulfate solution on the plants and soil.

prune

Since summer azalea has weak resistance and is very susceptible to disease, the withered flowers should be pruned in time to prevent them from falling into the soil and breeding bacteria. The withered flowers should be pruned as soon as possible when the flowers are 70% to 80% in bloom.

July and August are the peak flowering periods of summer azalea. Pruning must be completed before this time, otherwise it will affect its flowering in the second year.
