What fertilizer is good for azalea

Overview of Azalea Fertilization

Rhododendron likes warmth and is suitable for growing in an environment of 15-25℃. It likes fertilizer and needs more flower fertilizer to provide nutrient support during the growing season and flowering period.

Rhododendron has high requirements for fertilizer and needs to be fertilized frequently, but not too much. Add base fertilizer when planting. Choose compound fertilizer and dilute it and mix it into the potting soil. Apply phosphorus fertilizer once every 15 days from August to September. Some phosphorus and potassium fertilizers can be applied before flowering, and an appropriate amount of nitrogen fertilizer needs to be applied after flowering.

What fertilizer is good for azalea

Rhododendrons need to be fertilized frequently. Commonly used fertilizers are rapeseed cake, fish water, and grass juice water. It is best to use fertilizers with mild fertilizer power and long fertilizer effect. For domestic use, cow horns, sheep horns, and animal hoof slices can be used.

How to fertilize azalea

The base fertilizer for azalea can be mixed directly into the planting soil after it is prepared. Liquid fertilizer and foliar fertilizer need to be diluted before use, and the concentration used should not be too high.

You need to pay attention to the specific time of fertilizing azalea. It is not suitable to fertilize when the sunlight is very strong and the temperature is very high. It is best to do it in the evening and morning.

Spring fertilization

In the spring, you can use fermented fertilizer to fertilize azalea. The interval between fertilization can be about 10-15 days, which can meet the growth needs of the plant.

Fall Fertilization

In autumn, azaleas need to be given fertilizers mainly composed of phosphorus and potassium fertilizers twice, and they must be watered with clean water on the second day after each fertilization. Fertilization should be stopped after October to help the azaleas survive the winter safely.

Points to note when fertilizing azalea

If all the leaves of azalea turn yellow, it is usually caused by improper water and fertilizer. If the water and fertilizer are too much, you need to repot and loosen the soil, deal with the damaged roots, and replace the acidic potting soil.

Azaleas have a relatively high demand for sunlight, so after fertilizing, they should be shaded for a short period of time at noon. During the plum rain period, which is the period when azaleas sprout leaves and branches, they should be exposed to as much sunlight as possible.
