Camellia is no stranger to everyone. It is one of the top ten famous flowers in China. It not only has beautiful flowers and gorgeous colors, but also makes people love its charming fragrance. However, if you want to make the camellias beautiful, fertilization is a very key link, then how to fertilize camellias? The following are the fertilization methods and precautions of potted camellias. Follow the editor to have a look.

How to fertilize camellias, time / fertilizer / method

In the culture method of camellia, we have introduced that camellia is a kind of fertilizer-loving flower, which has more leaves, longer flowering period and requires a lot of fertilizer. Fertilization to camellias, there is a very troublesome, that is, fertilization can not be too much, otherwise easy to rot roots, resulting in camellia leaves yellowing, camellia leaves and other phenomena, seriously affecting the ornamental of the plant. As for how to fertilize camellias, time, fertilizer and method are very important. Let's move on.

II. Fertilization methods and matters needing attention of camellias (1) when to fertilize camellias, in the evening

How to fertilize camellias, first of all, you need to master the time. It is understood that to fertilize camellias, flower friends all use liquid fertilizer, and the best time to apply liquid fertilizer is in the evening, when the temperature drops, the soil is dry, and fertilization is just right. Note: water should be watered the next morning to dilute the fertilizer solution in the soil to facilitate root absorption.

(2) what kind of fertilizer, nitrogen, phosphorus and potassium fertilizer are used to fertilize camellias

1. Promote spring shoot and use nitrogen fertilizer

What fertilizer is used to fertilize camellias? According to the growth needs of camellias, the fertilizers used are different. When the temperature was about 18 ℃, camellias began to shoot in the shade, and nitrogen fertilizer was applied every 10 days until the spring shoot began to Lignification. After many times of nitrogen fertilizer irrigation, the spring shoots will grow very luxuriantly, creating very good conditions for camellias to bloom.

2. differentiation of flower buds and flower buds, application of phosphorus and potassium fertilizer

After the Lignification of the spring shoot, there will be a short period of semi-dormancy, when the camellias will turn to the growing period and the flower buds begin to differentiate. If you want camellias to bud, you should apply more phosphorus and potassium fertilizer and little or no nitrogen fertilizer at this time. This can not only control the excessive growth of camellia branches, but also promote and shorten the time of flower bud differentiation, which will be more conducive to the formation of flower buds.

(3) fertilization methods and principles of camellias.

After knowing when to fertilize camellias and what fertilizers to apply, the next step is the method of fertilizing camellias. First of all, in the process of fertilization, we should apply sufficient long-term fertilizer in combination with changing pots. According to the size of flowerpots, apply 3 to 80 grams of rotten cooked cake fertilizer powder or sun-dried chicken and duck manure in each pot, and mix them well with the subsoil under the pot.

Secondly, except for the hottest and coldest non-fertilization in summer and winter, the rotten dry cake water was applied once or twice a month. Fertilization method: peel off the soil at the edge of the basin about 2 cm, apply liquid fertilizer into the ditch and cover it with soil to avoid odor. In daily life, we can buy camellias special fertilizer in the flower shop, which is both hygienic and safe.

Finally, in order to make camellias grow better, extra-root fertilization was applied 1-2 times a month during the peak growth period, and leaves were sprayed with 0.2% to 0.3% potassium dihydrogen phosphate and 1% to 2% plant auxin. The principle of fertilization: light rather than heavy, light rather than thick, less and not more. We must adhere to the method of applying thin fertilizer frequently, especially not applying raw fertilizer.

(4) matters needing attention in fertilization of camellias

After mastering the method of fertilizing camellias, it becomes much easier to raise camellias, but when fertilizing camellias, there are several periods of time when people pay special attention to it:

1. During the blooming period of camellia buds, we must not fertilize it, otherwise it will cause falling flowers and buds.

2. in the high temperature in summer and semi-dormant period in winter, we can't fertilize camellias, otherwise it will cause the roots of the plants to rot.

3. If it is found that the branches of camellias are overgrown and the leaves are sagging for a long time, it shows that too much fertilizer is applied to camellias and should be stopped at this time.

4. Newly transplanted camellias or diseased camellias, it is best not to apply fertilizer. Thin fertilizer should be applied after the new and diseased plants are recovered and cured. In addition, camellias planted in autumn are generally not fertilized in the same year.

Generally speaking, camellia is a plant that needs a relatively large amount of fertilizer. We should apply fertilizer selectively according to the different growth stages of camellias in order to grow beautiful camellias. With regard to the fertilization method of camellias, the editor has introduced this, hoping to give you some help.

How to fertilize potted camellias? Fertilization methods and matters needing attention of potted camellias Camellia is one of the top ten famous flowers in China, and it is also one of the more famous flowers in the world. Camellia is widely planted in southern China. Camellia fertilization should be carried out selectively according to different growth stages. Topdressing is needed during the growing period of camellia, and quick-acting liquid fertilizer and chemical fertilizer should be applied. In the stage of branches and leaves, nitrogen fertilizer or nitrogen-based mixed fertilizer should be applied. Phosphate fertilizer or phosphorus-based mixed fertilizer is needed before flower bud differentiation, bud formation, growth and flowering. The mixed fertilizer based on phosphorus and potassium is the most suitable for autumn and winter. The main results were as follows: (1) nitrogen fertilizer promoted spring shoot camellia to start shady spring shoot at about 18 ℃. At this time, bud-destroying fertilizer based on nitrogen fertilizer should be applied once every 10 days until the spring shoot begins to Lignification. If possible, foliar spraying can also be carried out with a mixture of 1000 times of potassium dihydrogen phosphate, 1% urea and 300 times rice vinegar. After many times of root and foliar spraying, the spring shoot will grow very luxuriantly, the leaf can extend to the maximum, and the shoot can accumulate rich nutrients, creating good conditions for flower bud differentiation. (2) increasing the application of phosphorus and potassium fertilizer can promote the differentiation of flower buds and form the spring shoot of camellia. After Lignification, there will be a short period of semi-dormancy. At this time, the camellia changed from vegetative growth to reproductive growth, and the flower buds began to differentiate. If you want to make camellias produce more buds, you should apply more phosphorus and potassium fertilizer, and no or less nitrogen fertilizer. If the small camellias grow mainly, it is still dominated by nitrogen fertilizer, and no or less phosphorus fertilizer is applied. Foliar spraying with 1000 times potassium dihydrogen phosphate, a small amount of borax and rice vinegar can not only control the excessive growth of camellia branches, but also promote and shorten the time of flower bud differentiation, which is beneficial to the formation of flower buds. (3) it is not suitable to apply fertilizer in midsummer, let alone thick fertilizer, the weather is hot in midsummer, the growth of camellias is slow or half-paused. It is not suitable to apply fertilizer at this time, and special attention should be paid to not applying thick fertilizer. If the soil is barren, thin liquid fertilizer can be applied in combination with watering to improve the soil quality. (4) the mixed fertilizer based on phosphorus and potassium fertilizer was properly applied in autumn, which belongs to the period of nutrient accumulation of camellia plants. In order to survive the winter safely, the mixed fertilizer based on phosphorus and potassium fertilizer can be applied every half a month, combined with foliar spraying to promote plant health and improve the cold resistance of camellias. (5) dilute phosphorus and potassium liquid fertilizer should be applied in winter. Camellias in cold winter enter semi-dormancy period. Camellias enter the cellar, vegetative growth has entered dormancy, do not need much fertilizer. However, its reproductive growth has not completely stopped, and it is in the season of flowering or preparing for flowering, so it should be combined with watering and applying thin liquid phosphorus and potassium fertilizer. Do not apply thick fertilizer. How to fertilize potted camellias? Fertilization techniques of potted camellias

Potted camellias are very popular potted flowers. How to fertilize potted camellias? Today, I would like to share with you the fertilization technology of potted camellias.

Fertilization of camellias should be carried out selectively according to different growth stages of camellias.

Organic tea peanuts need topdressing for a long time, and quick-acting liquid fertilizer and chemical fertilizer should be applied. In the stage of branches and leaves, nitrogen fertilizer or nitrogen-based mixed fertilizer should be applied. Phosphate fertilizer or phosphorus-based mixed fertilizer is needed before flower bud differentiation, bud formation, growth and flowering. The mixed fertilizer based on phosphorus and potassium is the most suitable for autumn and winter.

(1) nitrogen fertilizer promotes spring shoot.

Camellias usually begin to bloom in the shade at about 18 ℃. At this time, bud-destroying fertilizer based on nitrogen fertilizer should be applied once every 10 days until the spring shoot begins to Lignification. If there are conditions, foliar spraying can be carried out with salt solution at the same time. After many times of root and foliar spraying, the spring shoot will grow very luxuriantly, the leaf can extend to the maximum, and the shoot can accumulate rich nutrients, creating good conditions for flower bud differentiation.

(2) increase the application of organic fertilizer and potash fertilizer to promote flower bud differentiation and form flower buds.

The spring shoot of camellia is full, and after Lignification, there will be a short period of semi-dormancy. At this time, the camellia changed from vegetative growth to reproductive growth, and the flower buds began to differentiate. If you want to make camellias produce more buds, you should apply more phosphorus and potassium fertilizer, and no or less nitrogen fertilizer. If the small organic camellias grow mainly, it is still dominated by nitrogen fertilizer, and no or less phosphorus fertilizer is applied.

(3) it is not suitable to apply fertilizer in midsummer, let alone thick fertilizer.

When the weather is hot in midsummer, camellias grow slowly or fall into a semi-stagnant state. It is not suitable to apply fertilizer at this time, and special attention should be paid to not applying thick fertilizer. If the soil is barren, thin liquid fertilizer can be applied in combination with watering to improve the soil quality.

(4) appropriate application of mixed fertilizer mainly composed of organic fertilizer in autumn.

The sky is high and cool in autumn, which belongs to the period of nutrient accumulation of camellia plants. In order to survive the winter safely, the mixed fertilizer based on farm manure can be applied every half a month, combined with foliar spraying to promote plant health and improve the cold resistance of camellias.

The above is the fertilization technology of potted camellias. Friends who like camellias can refer to these methods so as to fertilize potted camellias scientifically.
