"The Shu kingdom once smelled zizhi birds, and Xuancheng also saw azaleas. One called one ileum and one broken, three springs and three months remember three bars. ”
Rhododendron is an evergreen shrub of the genus Rhododendron, which is often called Yingshan Red and Mountain Pomegranate. It is named after the cuckoo birds, which mourn day and night and cough blood and stain the flowers that are red all over the mountain.
Rhododendron generally blooms in spring, the flowers are clustered, the corolla is funnel-shaped, and the flowers are lush and colorful, including red, light red, apricot red, snow blue, white, etc., and there are single-petal and heavy-petal varieties. Because the corolla is bright red, it is a famous flower plant and has high ornamental value. It is divided into "five major" strains: the spring crane strain, the summer cuckoo strain, the western azalea strain, the eastern azalea strain, and the alpine rhododendron strain.
In recent years, the peak sales season for azaleas has been in January and February before the Spring Festival. Especially in the flower market in the northern region, the commercial azalea is the main force of the New Year flower. Most of these potted plants are delicate varieties cultivated in the south, greenhouses, and out-of-seasons, and the small azaleas that are promoted by various chemical agents are "flowers in the greenhouse", which are good-looking at the time, but after the flowers are thanked, they always give people a look of loneliness that has gone to no trace. A phenomenon that followed was "buying flowers before the festival and throwing them away after the festival", which made people heart-wrenching.
What exactly does the family do to care for azaleas? What do you need to pay attention to? Today, the courtyard scenery tree will discuss with you.
Rhododendrons prefer acidic soils and grow poorly or even do not grow in calcareous soils.
Rhododendron likes cool, moist, ventilated semi-shaded environment, both afraid of extreme heat and cold, the growth temperature is 10 ° C to 30 ° C, summer to protect the sun and shade, avoid the sun exposure, suitable for growing under the scattered light of light intensity is not large, the light is too strong to be burned. In winter, attention should be paid to keeping warm and cold, and measures should be taken to prevent cold and winter below 5 °C.
Rhododendron prefers well-drained acidic soils, the soil is required to be loose, fertile, rich in humus, and should not be waterlogged, otherwise it is not conducive to the normal growth of rhododendrons. The potted soil is planted with humus soil, sand soil and same soil (7:2:1).
Rhododendron is a shade-loving plant, commonly found in mountains or under pine forests, overgrown, and is a typical acidic soil indicator plant. Direct sunlight from the sun is not good for its growth, so rhododendrons shade in summer to avoid strong direct sunlight. Place in plenty of sunshine in winter.
Rhododendron requires moist soil moisture to be moist and not wet, and often keep the potting soil moist, but do not accumulate water. Water once every 2-5 days in spring and autumn, and once a day in hot summer. Daily watering, do not use alkaline water, in the hot and hot summer, watering in the morning or evening, the soil temperature at these two times is relatively low, the temperature difference between water and soil, plant body is relatively small, the root system has little impact, otherwise the plant will also be due to sudden cold and hot and "cold". In other seasons, water the plants, try to be at noon, this time the temperature is relatively high, this time the plant prefers to drink water, but also easier to absorb. After entering the room in winter, the potting soil should be dried thoroughly before watering.
Do not use tap water directly when watering or fertilizing, and should be acidified (with ferrous sulfate or vinegar).
Flowers and plants generally like fertilizer, reasonable fertilization is the key to raising rhododendrons, rhododendrons like fertilizer and avoid thick fertilizer, in the spring and autumn growth season every 10 days to apply a thin cake fertilizer liquid water, can be used to tao rice water, peel, vegetable leaves and other fermentation. In the autumn, some phosphorus and potassium fertilizers can also be added. Remember to be "thin" and suitable for fertility.

Pruning the whole branch is an important measure in the daily maintenance and management work, which can regulate growth and development, so that the growth is vigorous. Generally according to the original tree shape slightly modified, do as you want, because of the tree shape. Mainly pruning the withered branches and flowers is useless. And remove the branches that no longer have ornamental value, such as crossed branches, over-dense branches, overlapping branches, and diseased and weak branches, and remove the residual flowers in time.
I am a courtyard tree, dedicated to the garden art around you and me, I hope that future generations can still see the green mountains and smell the flowers.
