How to make azalea bloom, what fertilizer to use before flowering

1. How to promote flowering

1. Acidic soil: The roots of azalea are relatively small. If it grows in heavy clay soil, it will not only affect flowering but also hinder growth. Therefore, in order to promote flowering, it is necessary to provide suitable soil, such as loose and fertile acidic soil.

2. Light conditions: In order for azalea to bloom, light conditions are indispensable. In spring and autumn, it should be exposed to more sunlight to meet basic light needs. In summer, it is necessary to pay attention to shading, and in winter, full light can be guaranteed.

3. Proper watering: To promote flowering, it is necessary to ensure sufficient water. It cannot tolerate drought, so it is necessary to water it reasonably during the growth and flowering period. Water it every three to five days during the spring and autumn growing seasons, water it once a day in summer, and keep it relatively dry in winter.

4. Top dressing of fertilizers: Flowering requires sufficient nutrients. Pay attention to top dressing of fertilizers during the normal growing period. It can make the plants strong and promote flowering. You can gradually stop fertilizing in winter.

5. Pay attention to pruning: Appropriate pruning is also required during daily maintenance. Cutting off the yellow leaves and dead leaves that appear during the growth can reduce the consumption of nutrients and accumulate nutrients to promote flowering.

2. What fertilizer to use before flowering

Applying phosphorus and potassium fertilizers before flowering can promote the differentiation of flower buds, the development of flower buds, and reduce the application of nitrogen fertilizers.
