Cultivation Techniques of Azalea sibirica

Azalea is what we call azalea in daily life, which is a wild rhododendron. Azalea not only has high ornamental value, but also its whole plant can be used as medicine. It has the effect of promoting qi and activating blood circulation, tonifying deficiency and relieving cough, and is distributed all over China. As spring approached, the planting time of Azalea gradually arrived. So how should we cultivate azalea? The following small series brings you the cultivation techniques of azalea. Let's take a look together!

1. Soil selection

Azalea's resistance to strong light is relatively low, so if it is exposed to direct sunlight, its growth will be affected to some extent. Therefore, when planting azalea, try to choose a place with shade. The planting soil shall be soft and fertile, and the irrigation and drainage shall be normal. If the soil is hardened and too alkaline, we shall replace the planting soil in time. Soil is the key to ensure the normal growth of azalea. After selecting the soil, we should do a good job of soil preparation, and carefully rake it to improve the quality of soil. Then apply enough base fertilizer to meet the nutrients needed for the germination of Azalea seeds.

2. Timely planting

After the selection and preparation work is completed, planting is generally carried out before germination in spring. Choose a place that is ventilated and has sufficient shade. Early spring is the best time to plant azalea. If it is cultivated in other seasons, then it must be set up with shade. After planting, the soil should be filled while treading, so as to increase the contact area between the roots of Azalea rhododendron and soil. But also pay attention to the intensity, not too tight, rhizome parts can be semicircular. This not only improves the soil's heat preservation ability, but also facilitates the drainage work in the planting process.

3. Water and fertilizer management

Azalea has moderate water requirements and can keep the soil moist without standing water. Soil drought should be watered in time, and attention should be paid to drainage in rainy season. And then at the end of each year to apply a sufficient base fertilizer to help azalea winter. In the spring of the second year, because azalea consumes too much nutrition for flowering at flowering, it needs topdressing once every half month or so to promote leaf bud germination. Rational fertilization is the key to ensure the healthy growth of azalea, while meeting the nutritional needs, but also to prevent excessive fertilizer caused by azalea fertilizer harm.

4. Pest control

Azalea is threatened by a lot of diseases and insect pests, including common root rot, black spot and so on. These diseases will threaten all parts of Azalea in different degrees, resulting in serious impact on the growth of Azalea. Therefore, we should pay attention to the management work when planting, strengthen the management of water and fertilizer, enhance the growth ability of azalea, and improve the disease resistance. And often observe the growth of azalea, if abnormal conditions are found, check out the specific reasons to make corresponding treatment in time.

The above is a simple introduction to the cultivation techniques of azalea, azalea cultivation techniques are not difficult, but also need to do a good job of management. To improve the resistance of azalea, the disease should be treated as soon as possible to avoid the spread of the disease, expand the affected area, and produce irreparable losses.
