Know the azaleas

1. Morphology: rhododendron is a deciduous shrub, 2-7 meters high, with many and slender branches, as well as stout branches. The most primitive rhododendron forest is preserved in the Baili rhododendron scenic spot in Guizhou, where the rhododendron is famous for its large flowers, colorful flowers and big trees.

2. Rhododendron, also known as Yingshanhong and pomegranate, is a very common flower in China, and in May 1985, rhododendron was selected as the sixth of the top ten famous flowers in China, which shows the popularity of rhododendron. At present, Jiangxi, Anhui and Guizhou all have azaleas as provincial flowers, and there are as many as seven or eight cities that have designated rhododendrons as city flowers. The editor will introduce you to some basic information about rhododendrons.

3. When it comes to Anku rhododendron, don't get me wrong. I'm not talking about a certain kind of flower, but a certain kind of flower. This kind of flower is not formed naturally, it is further developed from some kind of foreign rhododendron. At present, it is no problem for this kind of flower to be planted in our country.

4. Rhododendron is one of the rhododendrons, and it is also one of the most beautiful flowers in spring in the temperate regions of the Northern Hemisphere. In China, rhododendron is distributed in the Yellow River Basin, Northeast, North China, East China, Southwest, Northwest and other places. Rhododendron has a very beautiful color. The flowers are usually pink or purplish red, and there are few red and white varieties. Rhododendron flowers are very special, with five petals, very thick, can remain bright for a long time.

How do you grow azaleas?

Appropriate watering needs to pay attention to that the roots of azaleas are mostly capillary roots, usually can not be watered with heavy water, if caught in the rain, but also timely drainage to prevent root rot. Water can be watered once every two days in spring and autumn, and in the morning and evening at high temperature in summer. Sprinkler irrigation is best used when watering, which is more conducive to the absorption of plants.

Flowerpots in domestic azaleas, you'd better choose mud pots or purple sand pots. They have good air permeability and are beneficial to the respiration of the roots of the plant. In addition, it is best to choose a larger basin, because the plant grows faster, which can give its roots enough room to stretch. Flower soil because the growth of the plant needs a lot of nutrients, so it is best to choose a more fertile, breathable flower soil to raise it. Specifically, rotten leaf soil can be used.

Once my cousin gave me a pot of rhododendron, but no matter how I raised it, the rhododendron pot did not blossom. Later, I learned that the soil on my side was alkaline soil, but rhododendron would grow better in acidic soil. Therefore, in many cases, the rhododendron plant is thin and does not blossom, so first check to see if it is a soil problem. If the soil is indeed alkaline, low concentration vinegar water can be used to irrigate the soil to improve soil quality.

What are the characteristics of the genus Rhododendron?

Morphological characteristics: there are many species and shapes of rhododendron. From large trees (up to more than 20m in height) to small shrubs (only 250px-500px in height), the trunk is erect or creeping, with alternate or whorled branches. The species commonly cultivated in China are: rhododendron, summer rhododendron, honeysuckle, Yunyin rhododendron.

Genus name: Rhododendron L., Azaleaceae. There are about 800 species in the world, distributed in the north temperate zone, and there are 650 species in China. Morphological features: evergreen or deciduous, with various life forms. There are tall trees and low shrubs, and some species are barren. Branches often fascicled or subwhorled. Leaves simple, alternate and often fascicled with apical branches, leaf blade oblong or striate, entire; pinnately veined; petiolate.

Like half-shade and afraid of strong light: rhododendron is a negative plant, but it is also a long-day flower and tree, which is not only afraid of the scorching sun, but also needs not too strong sunshine for a long time. For example, soft sunshine is needed for a long time in the period of flower bud differentiation and bud formation. If the light is too strong, accompanied by high temperature and drought, chlorophyll is easy to be destroyed, the leaf color turns yellow, and the leaf edge is brown, which will affect flower bud formation and flowering.
