The growing environment and local conditions of azalea

Rhododendron Growth Environment and Conditions

Rhododendron is commonly found in sparse shrubs or under pine forests in mountains. It is grown in Fujian, Taiwan, Hubei, Hunan, Jiangsu, Anhui, Zhejiang, Jiangxi, Guangdong, Guangxi, Sichuan, Guizhou and Yunnan in China.

Rhododendron Growing Conditions

Rhododendron prefers a cool, humid, ventilated semi-shady environment. It cannot tolerate direct sunlight and needs shade in summer. In addition, it is suitable for planting in loose, fertile acidic soil and is difficult to grow in calcareous soil.

Rhododendron growth temperature

Rhododendron is not resistant to high temperatures and severe cold. The suitable growth temperature is between 12-25 degrees. The summer temperature is above 35 degrees. The new shoots and new leaves grow slowly and are in a semi-dormant state. If the winter temperature is below 0 degrees, frost damage is likely to occur.

Rhododendron growth process

New buds will grow in about a month after azaleas are planted, but they will not bloom that year. Generally, they need to be cared for for a growing season and will bloom in the second year. Azaleas bloom first and then grow leaves. The leaf shapes and colors are diverse, and the leaf shapes vary according to the variety. Common colors include red, white, yellow, pink, etc.

Azalea planting time and method

1. Rhododendron is suitable for sowing in spring from March to April. Its seeds are small, so the pots need to be cleaned and disinfected in advance, and the soil should also be sterilized. The potting soil should be acidic soil with good drainage, moist, fertile, and rich in organic matter.

2. After sowing, cover with a thin layer of fine soil, cover with glass or plastic film to keep warm, keep the soil moist, and place the pot on the front windowsill. After the seedlings emerge from the soil, the covering time needs to be reduced. When 2-3 true leaves grow in May-June, transplanting can be carried out.
