How to fertilize azalea with flower buds? Do you need to water it when fertilizing?

1. How to apply fertilizer

When the azalea grows buds, you can spray it with some foliar fertilizer. Fertilizing before the flowers bloom can promote the differentiation of flower buds, but after the flower buds appear, you only need to spray foliar fertilizer. However, once the flower buds have grown to a certain size, stop fertilizing. No fertilizer is needed during the flowering period. You can wait until the flowers wither before replenishing nutrients.

2. Whether to use watering

When fertilizing azalea, you can water it, but the amount of water should not be too much. Generally speaking, you should water the plant once the next morning after fertilizing it. This is to help the fertilizer dissolve so that the roots of the plant can absorb it better. Fertilization should be done when the soil is dry, and the time can be chosen in the evening, so as not to harm the growth of the plants.

3. Notes

1. Amount of fertilizer: Fertilizer should be applied to azalea in small amounts and frequently. Generally, no fertilizer is needed for 1-2 years because there is enough base fertilizer in the soil. If the plant is cultivated for 3-5 years, it is necessary to apply fertilizer every 15 days; for plants that have grown for more than 4 years, the amount of fertilizer applied each time is about 20g.

2. Concentration: It is a plant that likes fertilizer, but when fertilizing, be careful not to use concentrated fertilizer. During the growing season, fertilizer is usually applied in the form of dilute cake fertilizer water or self-fermented fertilizer. Fertilizer needs to be applied once before winter, but do not apply base fertilizer when repotting.
