Rhododendron fertilization, Rhododendron fertilization method and maintenance

1. Fertilization method

The fertilization of azalea should be determined according to the age of the flower. It is not advisable to apply fertilizer in the seedling stage. Phosphorus and potassium fertilizers can be added after 2-3 years of growth, and more nitrogen fertilizers can be applied to old plants. In addition, the time of fertilization should be controlled, which is usually carried out in spring and autumn. Before applying fertilizer, the fertilizer should be fully diluted and the water should be controlled for a period of time. After fertilizing, water the soil frequently to facilitate its absorption.

2. Maintenance Tips

1. Growing period: Azalea has two growing periods. One is spring. At this time, use decomposed cake fertilizer and apply it 3-4 times a month. Be sure to fully dilute it before applying. After autumn, it enters the second growing period, at which time the flower bud differentiation is interrupted. It is necessary to apply a certain amount of phosphorus and potassium fertilizers. Water the plant on the second day after fertilizing to avoid root burns.

2. Pre-flowering stage: Provide azalea with sufficient nutrients in the pre-flowering stage. At this time, phosphate fertilizer should be the main fertilizer, and a certain amount of potassium fertilizer can be added. Apply little or no nitrogen fertilizer as it will hinder flowering.

3. Late flowering period: Nitrogen fertilizer should be added immediately after the flowers fade. At this time, the plant lacks nutrients. Nitrogen fertilizer should be applied once every 10 days, which is more beneficial to the growth of branches and leaves. From August to October, you should add a certain amount of phosphorus fertilizer and apply it once every half a month, which will be very helpful for flowering in the second year.
