Introduction: Rhododendron has many different names, also known as Yingshan red, mountain pomegranate, etc., mainly distributed in the northern hemisphere temperate and subtropical, mainly produced in Southeast Asia and south pressure region, to the southwest of China Hengduan mountain area is the most abundant. Generally often in some scenic spots, often see the figure of rhododendrons, to the flowering period will usher in countless tourists to enjoy the flowers. However, azaleas can also be potted, and many flower lovers will potted plants on the balcony of the home and in the living room, which has high ornamental value. Some flower lovers do not know how to apply fertilizer correctly when maintaining rhododendrons, resulting in slow growth of rhododendrons, as well as fewer flowers and plant wilting. Below I will communicate with you about how to fertilize the rhododendrons so that the plants can grow rapidly and flourish, and the flowers are gorgeous and moving, hoping to help the flower lovers in need.
Rhododendrons are of great variety and are thorny shrubs or small trees. There are evergreen varieties and deciduous varieties, which are white at first and later become yellowish and bell-shaped. The flowers are gorgeous, the flowering period is relatively long, and it has the reputation of "flowers in the West" in China's folk. General rhododendrons are divided into spring azaleas, flowering periods from April to May, xia juan, flowering periods from May to June, east azaleas, flowering around the New Year's Day festival, west azaleas, will bloom around the Spring Festival, four seasons of rhododendrons, just maintain well, flowering throughout the year.
In the process of maintaining rhododendrons, rhododendrons are fertile flower plants, only by fertilizing well and maintaining sufficient nutrition, can the plants thrive, and different varieties of rhododendrons can bloom as scheduled. As for how to fertilize the azaleas, what time periods to fertilize well, what fertilizer to use, etc., I will share my personal experience with you below, hoping to help flower friends in need.
<h1>How to prepare a fertile and high-quality nutrient soil for rhododendrons? </h1>
For rhododendrons to thrive and flourish, it is necessary to start with the preparation of a fertile and high-quality nutrient soil. Whether it is a newly bought rhododendron seedling or a rhododendron pile that has been maintained for many years, when changing pots, a new cultivation soil is needed to make the rhododendron grow better. Generally, the soil for rhododendrons needs to be fertile, loose, well-drained and slightly acidic soil, and it is not possible to use soil with too high alkalinity or calcium soil with poor air permeability, which will lead to poor growth of rhododendrons. When making cultivation soil for rhododendrons, it can be composed of a mixture of saprophyll soil, river sand and horse manure chips, which can meet the growth needs of rhododendrons.
<h1>Fertilization methods at the seedling stage of rhododendrons, as well as fertilizers to be fertilized. </h1>
Timely fertilization, that is, when the rhododendron needs fertilizer, and then fertilize, the rhododendron wants to be well maintained, it needs to learn to fertilize from the seedlings, according to the different growth cycles, to properly fertilize, in order to maintain the healthy growth of the plant. In general, fertilization of flowers and plants is the most appropriate when the leaves of the plant are faded and the growth is weak and slow.
1, rhododendron can use a lot of fertilizer, you can use alum water, or rotten cake fertilizer, fishmeal, broad beans, etc., after decay and mixed with water, to the rhododendron for watering, can play a role in increasing nutrition, rhododendron can grow rapidly. Generally prepared a fertile nutrient soil, just on the pot does not need to fertilize, such as fertilization may cause fertilizer damage, need to go through 1 to 2 months of consumption time, and so the nutrients in the soil are consumed some, according to the growth of the plant fertilization.
2, rhododendron is a flowering plant, not a foliage plant, then fertilization is not only to make the plant leafy, but also according to different times how to fertilize, in order to make the rhododendron flower to the flowering period can bloom as scheduled. Seedling period is mainly still long branches and leaves, at this time fertilization, it is mainly based on fertilizer with higher nitrogen content, you can apply some decomposing organic fertilizer, and when you use nitrogen fertilizer, you can also apply it together. At the same time, it is necessary to pay attention to the amount of fertilizer, do not apply too much fertilizer at one time, as well as strong fertilizer, keep sufficient water, and do not let the seedlings lack water, in order to promote the rapid and robust growth of seedlings.

Rhododendrons grow strongly from seedlings, and after they become seedlings, the fertilization method needs to be paid attention to at this time, such as improper fertilization will not flower, or less flowering, serious will grow in vain and encounter fertilizer plant wilting. When the rhododendron flowers become seedlings, at this time fertilization, you also need to pay attention to the amount of fertilizer used, appropriate fertilization, you can apply some cake fertilizer or decomposed organic fertilizer. Near the flowering period, fertilization needs to pay attention to, can not apply a large amount of nitrogen fertilizer, will lead to excess nitrogen elements, will only grow leaves without flowering, at this time fertilization, should be mainly phosphorus, potassium fertilizer- mainly, can promote flower bud differentiation, but also let the rhododendron flower early flowering, more buds, to flowering time, open a large beautiful flower.
<h1>Seasonal fertilization of rhododendrons. </h1>
First, spring: This is the peak season for rhododendrons, and it is necessary to maintain adequate nutrition. If it is in the flowering stage at this time, it cannot be fertilized in large quantities, and it is not easy to over-fertilize during the flowering period. The growing rhododendron can apply more fertilizer, about 10 to 15 days, and can apply a decomposing organic fertilizer or other fertilizer to allow the plant to thrive.
Second, summer: at this time, the climate is relatively hot, the temperature is relatively high, and the rhododendrons will enter a semi-dormant state with the high temperature. At this time, fertilization needs to be noted, generally just into the summer, has not yet entered the dormancy, can be fertilized, but after the summer, the temperature is too high, into the semi-dormant after fertilization can not be fertilized. If fertilization is applied, it will break the dormancy, which will affect the flowering of the flowering period, resulting in no flowering and less flowering.
Third, autumn: at this time is also in the azalea growth is better, should also maintain adequate nutrition, just passed the high temperature of the summer, then also need sufficient nutrients to provide growth. After the rhododendron arrives in autumn, it takes about 15 to 25 days to fertilize, until the beginning of winter, you should reduce the fertilization and control of fertilizer.
Fourth, winter: Generally just into the winter, a small amount of fertilization can be carried out to allow the plant to continue to grow, but at this time the plant will also grow slowly, remember not to apply thick fertilizer. Rhododendrons will also enter semi-dormancy with the severe cold of the weather, and the demand for fertilizer at this time is not much, and fertilization should be controlled in winter.
<h1>Fertilization methods for rhododendrons, as well as time periods and treatment after fertilization. </h1>
Potted rhododendron fertilization, should avoid fertilization at high temperatures, otherwise it is easy to hurt the roots, especially at noon, the temperature is relatively high, this time should not be fertilized, should be in the evening when the weather is cooler, fertilization effect is better. Fertilization should be loosened some soil surface, can make the thin fertilizer water better penetrate, after fertilization can spray some water to the foliar surface, so as not to residual fertilizer pollution of the foliage, the next day of fertilization needs to be watered once, to avoid a large number of thick fertilizer residues in a part, causing fertilizer damage. Fertilization should adopt the principle of "eating less and eating more meals", that is, "thin fertilizer and diligent application", which can make the rhododendron grow vigorously and bloom as scheduled.
summary
Learning to fertilize rhododendrons can make the seedlings thrive into old piles, which not only maintains the health of the plant, but also enables the plant to grow rapidly, flourishing, flowering, and large flowers. If no fertilizer is applied, it will lead to slow plant growth, as well as little or no flowering, which will cause fertilizer damage and plant wilting. When fertilizing a cuckoo, remember that although it prefers to be well nourished, it should not be excessive, and it can be evenly and appropriately.
