How to care for azaleas during Chinese New Year? Understand the key care points in one article
Every year during Chinese New Year, it is often the peak season for the flower market, and New Year flowers sell extremely well during Chinese New Year. Whether as a gift or placed in one's own home, New Year flowers are a good choice. Azaleas are also a relatively common New Year flower, but because azaleas are an ordinary variety and have a short flowering period, cultivation methods still need attention when caring for them during Chinese New Year.
Azalea
Azalea petals are very delicate and afraid of low temperatures, especially wind. Therefore, when carrying azaleas home, be sure to cover the flowers with windproof and heat-insulating materials. If they are severely frozen and the roots are damaged, the entire plant may die. Azaleas with unopened buds are relatively more cold-tolerant. In addition, many people dislike the original flowerpot and ask to repot, but doing so is actually very harmful. Because repotting can damage the root system, and at this time it is most susceptible to freezing. In addition, after repotting, water should generally be given immediately, and after 3-5 days of root recovery, the roots can recover. If the root system is too badly damaged, it may not recover.
At home, pay attention to controlling the temperature at around 20°C and increasing indoor humidity as much as possible. Some people think that spraying water on the leaves and flowers can humidify, but this only works when the flower roots are damaged. When the roots are intact, it instead makes the flowers bloom faster, so increasing indoor humidity still depends on a humidifier. Secondly, watering should not be too frequent, and the plant should not be exposed to strong sunlight, as both will speed up flowering. Because azaleas basically complete their "mission" after the flowering period ends, and fertilizer was also added during forcing, so no fertilization is needed.
How to grow azaleas, how should azaleas be cared for?
With the continuous improvement of material life, people's enjoyment of life is also constantly increasing. As a result, people understand more and more about plants, and will also grow one pot to make their lives more romantic. I do not know whether any of you have chosen a plant to grow for yourselves. If not? Then it is just right to take a look together at the azalea, one of China's top ten traditional famous flowers!
Introduction to azaleas
Azaleas are also called mountain pomegranate and yingshanhong, and are deciduous shrubs belonging to the Ericaceae family. There are about 900 azalea varieties in the world, and China has more than 530 of them, so it can be said that China is the country with the most azalea distribution. As for this plant, its branches are very numerous but very slender. Next, the azalea's flower buds are spherical, while the calyx has 5 deep lobes, and the lobes are triangular-ovate, with a length of 5 mm. As for the azalea's flowering period, it is from April to May, and the fruiting period is from June to August.
Azalea cultivation methods
Under natural cultivation conditions, the flowering period of spring azaleas is from April to May, and that of summer azaleas is from May to June. No matter what kind of azalea it is, correct methods should be adopted when cultivating it, and the following are the conditions required when growing azaleas.
1 Light/temperature: When growing, it can be moved outdoors in April and placed in a wind-sheltered and sunny place. In summer, also pay attention to shading to avoid direct strong light. Next, the growth temperature is 15-25°C, and the maximum temperature is 32°C.
2 Water: After the first planting and after changing the soil, water once so that the roots and soil fully contact, which helps the roots survive. During growth, also pay attention to watering. After March, increase the frequency of watering, especially in summer, and keep the potting soil moist. In September, reduce the frequency of watering.
3 Soil: Loose, fertile, and rich in humus is best, and acidic sandy soil is the best.
4 Fertilization: Reasonable fertilization is the key to growing azaleas. This plant has fine roots and avoids strong fertilizer. Fermented fertilizer made from rice water, fruit peels, vegetable leaves, and the like can be used.
Precautions for growing azaleas
When growing azaleas, prune the plant. If you want to control the flowering period yourself, move the plant into a 20°C greenhouse in January or 20 days before Chinese New Year, so you can enjoy azaleas during Chinese New Year. Of course, the flower language of azaleas is "always belong to you," the joy of love, and restrained desire. Besides ornamental value, it can also be used as medicine, with effects such as anti-inflammatory and antibacterial, analgesic, and antitussive.
Summary: The above are the key points for planting azaleas and the precautions for this plant that the editor has organized for users. It is also worth noting that when growing them, attention should also be paid to pest and disease control.

Key care points for Belgian azaleasBelgian azalea is a world-famous woody flower. Its plant shape is short and sturdy, the crown is compact, developed and thick, and the fibrous roots are numerous. The leaves are relatively thick, deep green and glossy, with few hairs. The flowering period is from January to May, and the flowering period can be controlled under greenhouse conditions. The flowers are double, with forms such as ruffled edges, rolled edges, and wavy edges. The flower colors are very rich, the flowers are numerous, and the flower diameter is 6-8 cm, with the largest reaching 10 cm.
The suitable growth temperature for Belgian azaleas is between 15-30°C, the day-night temperature difference is about 103v, the environmental humidity is above 600h, the physiological extreme minimum temperature can tolerate -3°C low temperature (natural overwintering) and short-term 40CC high temperature, but long-term too high or too low temperature, or too small a temperature difference, is unfavorable to growth. Suitable soil is slightly acidic (pH4.5-6), loose, water-retaining, and breathable, such as peat, pine needle soil, humus soil, decomposed sawdust, spent mushroom material, red sandy soil, sandy mountain soil, etc. If the acidity is insufficient, an appropriate amount of ferrous sulfate can be used to adjust it. Belgian azaleas need 50%-70% shading from late spring to early autumn. In winter, the greenhouse may not need shading and should maintain a nighttime temperature above 3°C. In the Jiangnan region, double-layer arched sheds are used for covering; in warm southern areas, a single layer can be used for overwintering, but occasional cold waves still require attention to prevent freezing damage; in the north, solar greenhouses and heated greenhouses are mostly used. In winter and spring, the greenhouse interior should be ventilated to keep the temperature inside not exceeding 32°C.
Water management for Belgian azaleas is relatively important. Generally, keep it moist and on the wetter side, and it must not be too dry, so as not to affect normal growth and development. Usually, watering should use neutral or slightly acidic surface water. In the north, if groundwater is used, it must undergo desalination or acidification treatment. For potted plants, plastic pots, seedling cups, and clay pots can be used. Before planting, 1%-3% rotted cake fertilizer or 0.5% high-nitrogen slow-release fertilizer can be added to the substrate. Regular topdressing is mainly nitrogen fertilizer (ammonium nitrogen). Generally, 5 grams of raw cake or rotted dry cake per pot (flowerpot with a diameter of 15-20 cm) and 0.1% urea solution are used. During the flower bud differentiation period, 0.1% urea plus 0.19'0 potassium dihydrogen phosphate is applied once every 15-20 days. If new shoots show yellowing due to iron deficiency, 0.2% ferrous sulfate can be poured once a week until recovery.
Belgian azalea shaping is mainly based on pinching and topping, carried out once every 60-80 days. The new shoots should be pinched level to help form a compact and even shape. If flowering is required for New Year's Day and Chinese New Year, the last pinching time in the Jiangnan area is suitable from early June to early July, can be postponed in the south, and should be earlier in the north.
The main pests of Belgian azaleas are: leaf roller moth (rolls leaves and eats leaves), scale insects (causing small-leaf disease), and lace bugs (causing white spots on the leaf surface and dirty spots on the leaf underside). Corresponding pesticides include: 2000 times beta-cypermethrin to control leaf roller moths, lace bugs, etc.; 1000 times tetradifon and 1500--200(] times trialkyne mite to control scale insects. The main diseases of Belgian azaleas include black spot, spotted leaf drop, stem blight, etc. Fungicides such as 600 times mancozeb, 3000 times difenoconazole, 600 times copper hydroxide, 600 times thiophanate, and 2000 times procymidone can be used in rotation for control, spraying once every 10-20 days. During long periods of rain, prevent before rain and treat after rain; during the flowering period, attention should be paid to the control of gray mold. At the beginning of the flowering period, use gray mold control drugs such as procymidone, iprodione, and vinclozolin once every 7-10 days, for a total of 2-3 sprays. If you want to improve flower quality, you can spray foliar micro-fertilizer (such as Pen Shi Bao, Sui Man Feng, Ye Mian Bao) 2-3 times every 7-10 days before flowering (for specific concentrations, refer to the instructions). Generally, no fertilizer is applied during the full flowering period. In addition, during the flowering period, attention should be paid to water supply, and it must never be allowed to dry out, and wilted flowers should be removed promptly. Too low a temperature (below 8°C) or too high a temperature (above 30°C) is also unfavorable to flowering (Reporter Anonymous)
