Cultivation methods and precautions of Belgian azalea

Belgian azalea, also known as the four-season azalea, can bloom all year round, even in the cold winter, as long as the temperature and humidity are suitable, it can still bloom, so it is very easy to cultivate.

How to grow Belgian azalea

1. Soil

Belgian azalea prefers loose, fertile, acidic soil, so it is not recommended to use clay or alkaline soil. Potted plants can be cultivated with special soil or general soil. If planted in the northern region, it is best to add an appropriate amount of ferrous sulfate to the water before each watering to neutralize the water quality.

2. Sunlight

Belgian azalea is not resistant to strong light exposure. It is best to keep it in a semi-shaded environment with scattered light on a daily basis. Otherwise, if the light is too strong, it will easily wither. The suitable growth temperature for Belgian azalea is between 12-25℃, and it needs to be ventilated and cooled in summer.

3. Watering

Belgian azalea likes moisture. During the growing period, the soil needs to be kept slightly moist. Water should be sprayed around it frequently to maintain the humidity of the environment. However, water accumulation in the soil should not be allowed, and water should also be properly controlled during the flowering period.

4. Fertilization

If you want the Belgian azalea to bloom more flowers, you need to apply thin fertilizers frequently during the growing season. It is best to apply thin, decomposed fertilizer water once every half a month to promote its vigorous growth. You can also apply some phosphorus and potassium fertilizers before flowering.

5. Pruning

The flowers of Belgian azalea are not easy to fall off after they bloom. The water content of the entire petals is relatively high. If they are not removed in time, it will easily cause the plant to become diseased and affect the overall ornamental effect. Therefore, we must remove the remaining flowers during maintenance, which can reduce nutrient consumption and promote the growth of new buds.

Belgian azalea maintenance precautions

The potting soil of Belgian azalea needs to be changed once a year after cultivation. The best time to change the pot is after the flowering period in spring. You can change it to a large, low pot to provide space for the growth of the roots. It is recommended to use a ceramic pot with very good drainage and air permeability for planting.

After repotting, water the Belgian azalea thoroughly, then place it by the north window to slow down the growth, and spray the plant with water twice a day in the morning and evening. It is recommended to put a transparent plastic bag in it one week after repotting. Poke a few small holes in the plastic bag for ventilation. This will increase the air humidity and prevent dehydration, withered leaves and yellowing leaves.
