Rhododendron is one of the top ten famous flowers in China, which is widely distributed in our country and is a famous ornamental object. Bai Juyi, a poet of the Tang Dynasty, once praised the azaleas that "both peaches and plums are colorless, reflecting that hibiscus is not a flower."

So far, nearly a thousand varieties of Yingshanhong have been found, and more than 10,000 varieties of azaleas have been artificially cultivated.

The propagation method of rhododendron can be propagated by sowing, cutting, grafting, tillering and so on. Generally give priority to cuttage, the procedure is simple, and the flowering is quick. The best cutting time is the rainy season. The cuttings are cut at the base of the cuttings after the new buds are formed, which is the easiest to survive.

After about 2-3 weeks, the incision can gradually heal and take root, and after the cuttings take root, the light time can be increased. After about 2 months, thin cake fertilizer and water can be applied to promote its growth. It can be planted in pots in the following spring.

Sowing and reproduction can be sowed in a wooden frame or tile basin, the bottom of the basin should be covered with vermiculite or leaves to facilitate drainage, and the basin should place mud or rotten leaf soil mixed with an appropriate amount of sand, which is in line with the mouth of the basin (slightly shallower than the mouth of the basin), and then sift with a layer of fine soil to sow the seeds on it, no longer covered with soil, covered with glass, preferably lined with a newspaper to keep moist, about 3-4 weeks later, it can be germinated and unearthed. At this time, take off the glass cover, accept the light, and spray water properly, wait for the seedlings to have 3-4 leaves before planting.
