Culture methods and matters needing attention of Rhododendron

Cuckoo, also known as Yingshanhong, it is said in ancient times that cuckoos wailed day and night, and the blood stained the flowers all over the mountains, so it was named Yingshanhong. China first had records of azaleas in the Han Dynasty, and the cultivation history of azaleas has been more than a thousand years. Many ancient poets have written poems about azaleas, especially Bai Juyi, who not only wrote poems to praise but also cultivated them personally. Rhododendron blossoms in bright colors, is a world-famous flower plant, with high ornamental value, and now it is widely planted in all parts of our country. So how should we cultivate azaleas?

Culture methods and matters needing attention of Rhododendron

1. Temperature

Azaleas are generally born in mountain thickets or pine forests at an altitude of 500 to 1200 meters above sea level. They like cool, moist and ventilated semi-shady environments and are afraid of heat and cold. The suitable growth temperature is between 12 degrees Celsius and 25 degrees Celsius. Azaleas in summer should pay attention to sunscreen and shade, when the temperature is above 30 degrees Celsius, the growth of azaleas will be very slow, or even enter a semi-dormant state, can not accept the hot sun exposure. In winter, we need to keep warm and prevent the cold, especially the azaleas cultivated in the open field in winter should pay special attention to the cold, otherwise the azaleas are difficult to survive the winter smoothly and are prone to frost injury, so it is best to control the temperature of the azaleas in the environment above five degrees Celsius.

2. Soil

Rhododendron likes the acid soil with loose and fertile, good drainage and good air permeability, but does not grow well in calcareous soil, and does not like the clayey alkaline soil. Because rhododendron likes the characteristics of acidic soil, many pedologists often use rhododendron as an indicator crop of acidic soil. It is suggested that rotten leaf soil, peat soil and sandy soil should be mixed according to the proportion of 5:2:3. At the same time, azaleas, as plants that like shade, cannot accept the direct light of the sun, so azaleas are generally cultivated in shaded places. It is worth noting that the growth of azaleas consumes nutrients in the soil more quickly, and the nutrients in the soil will generally be absorbed after a year or two. at this time, potted azaleas need to be replaced with new and well-nourished potted soil. so that azaleas can continue to grow healthily.

3. Watering

Azaleas like moist but not moist soil, so we usually pour a little less water in early spring to keep the soil moist. In late spring and early summer, azaleas are in the preparatory period before blooming, and water demand is greatly increased. At this time, azaleas need to be watered more. When the summer climate is hot, not only enough water is needed, but also some water is sprayed on the surface of azaleas to keep moist. When the weather temperature drops gradually in autumn, it is necessary to appropriately control the amount of watering to make the soil drier moderately, and finally to reduce the amount of watering during the dormant period in winter.
