Rhododendron is one of the top ten traditional Chinese flowers, and its flowering period is basically concentrated in winter and spring, so it is also a flower that is sold in the Spring Festival. Many flower lovers will plant a pot of rhododendrons at home, but when maintaining and azaleas, they often encounter the situation that the azaleas are not in bloom, and there are five main reasons for this phenomenon.
1. Illumination
Rhododendron is a plant that likes sunlight, so when we care for rhododendrons, we should put them in a place with bright light or astigmatism. Only by ensuring that it is exposed to sufficient sunlight can it promote its flowering, but it should be noted that it cannot be directly placed in direct sunlight, especially in the summer, the temperature is higher, at this time we should give it shade to avoid the heat.
2. Temperature
The second point is the temperature of the rhododendron, the rhododendron is not drought-tolerant nor hardy, the most suitable growth temperature is about 15 to 28 degrees, so in the summer we should pay attention to shade it, the temperature is too low in the winter, we have to move it indoors to maintain, the temperature will drop greatly around October, then we can move it indoors to maintain, the temperature is best not lower than 10 degrees, the temperature above 10 degrees can let the azaleas grow freely.
3. Water
Rhododendron likes a humid air environment, autumn is generally about 2 to 3 days apart, we have to water it once, if it is in the hot summer, then we need to water it once a day. When watering, special attention should be paid not to water the rhododendrons with alkaline water. Many people in the summer to water the rhododendron, have ignored a problem, we can not directly use cold water to water the rhododendron, which will cause the temperature difference between the potting soil and water, a cold and a hot is very easy to cause the root system can not absorb, will affect the growth of rhododendron.
4. Fertilization
Rhododendron peanuts grow slowly, and a large part of the reason is related to fertilization. The flowering period of rhododendron is in winter and spring, during the period when the rhododendron is pregnant with flower buds, we have to apply some phosphorus and potassium fertilizer to it, and we can also use some homemade liquid fertilizer made of rice water, peel or vegetable leaves. At the same time, wait until around April to May, the rhododendron will slowly wither, at this time the rhododendron has consumed a lot of nutrients, so at this time we need to fertilize it, every 15 days or so to fertilize it, so that its leaf buds will gradually germinate, the night shoots will also be elongated, and after the ambush, then the rhododendron will slowly enter the dormant period, most of the branches will stop growing, at this time we can stop fattening it.
5. Precautions
In addition, the growth of rhododendron is relatively fast, although its growth has a certain plant type, but we still have to prune it frequently, otherwise the branches inside the rhododendron are easy to see no light, thus affecting the healthy growth of internal branches. Potted rhododendrons for about 1 to 2 years, the nutrients in the potting soil are almost consumed, and the potting soil at this time is not conducive to the absorption of rhododendron root system. So we have to change the pot treatment for it, so as to ensure that the cuckoo has enough nutrients.
