CATDOLL : CATDOLL:What's wrong with my azalea leaves?

Azalea is what we call rhododendron in our daily life, which is a kind of wild rhododendron.

Azalea not only has a high ornamental value, but the whole plant can also be used as medicine. It has the effects of promoting qi and blood circulation, replenishing deficiency and relieving cough, and is distributed throughout my country. As spring approaches, it is gradually time to plant azalea. So how should azalea be cultivated? The following editor brings you the cultivation technology of azalea, let's take a look!

1. Soil selection

Azalea has a low tolerance to strong light, so if it is exposed to direct sunlight, it will have a certain impact on its growth. Therefore, when planting azalea, try to choose a place with shade. The planting soil must be soft and fertile, and the drainage and irrigation must be normal. If the soil is compacted and too alkaline, then we must replace the planting soil in time. Soil is the key to ensure the normal growth of azalea. After selecting the soil, we must do a good job of land preparation, fine-tune it, and improve the quality of the soil. Then apply enough base fertilizer to meet the nutrients required for the germination of azalea seeds.

2. Plant at the right time

After the site selection and land preparation work is completed, planting is generally carried out in spring before buds sprout. Choose a place with good ventilation and sufficient shade. Early spring is the best time to plant azaleas. If you plant it in other seasons, you must set up a shade shed. When filling the soil after planting, you should step on it while filling to increase the contact area between the roots of the azalea and the soil. But you should also pay attention to the strength, not too tight, and the rhizome should be semicircular. This can not only improve the soil's ability to keep warm, but also facilitate drainage during the planting process.

3. Water and fertilizer management

Azaleas have a moderate demand for water, just keep the soil moist without water accumulation. Water the soil in time when it is dry, and pay attention to drainage in the rainy season. Then, apply enough base fertilizer at the end of each year to help azaleas survive the winter. In the spring of the second year, because azaleas consume too much nutrients for flowering during the flowering period, they need to be topdressed with water-soluble fertilizer every half a month or so to promote leaf bud germination. Reasonable fertilization is the key to ensuring the healthy growth of azaleas. While meeting the nutritional needs, it is also necessary to prevent excessive fertilizers from causing fertilizer damage to azaleas.

4. Pest and disease control

Azalea is threatened by many diseases and pests, including common root rot and black spot. These diseases will threaten various parts of azalea to varying degrees, causing the growth of azalea to be seriously affected. Therefore, when planting, we must pay attention to good management, strengthen water and fertilizer management, enhance the growth ability of azalea, and improve disease resistance. And we must often observe the growth of azalea. If any abnormal situation is found, we must check the specific cause and take corresponding measures in time.
