Can camellia be fertilized organically? What kind of flowers can be fertilized by the fertilizer of

With natural fertilizers, yours may not work.

In different growth periods, different fertilizers should be applied to camellias. When planting and repotting, it is necessary to apply basal fertilizer to the soil, usually using well-rotted organic fertilizer, but also phosphate fertilizer or bone meal. If the soil is alkaline, it is often necessary to water alum fertilizer water or ferrous sulfate solution to adjust its pH.

In addition, compound fertilizer should be supplemented during the growth period, and phosphorus and potassium fertilizer should be added before flowering. 2. How to fertilize 1. Spring tip fertilization: After spring, as the temperature continues to rise, camellia will also begin to germinate spring shoots, and it needs to be fertilized to promote germination.

Usually once every 10 days, the fertilizer should be mainly nitrogen fertilizer, and it will be applied until the spring shoots are lignified. In addition, you can also spray a little foliar fertilizer, generally with potassium dihydrogen phosphate mixed with urea and rice vinegar. 2. Fertilization before flowering:

In the flower bud differentiation stage of camellia, it is necessary to control the amount of nitrogen fertilizer and apply phosphorus and potassium fertilizer instead, which can prevent plant growth, shorten the differentiation time, and promote flower bud formation. Usually applied once every 10 days, the fertilizer is mostly potassium dihydrogen phosphate, plus a little borax and rice vinegar, diluted and sprayed on the leaves. 3. Autumn fertilization:

Autumn temperatures begin to drop, but this is the time for nutrient accumulation, so it is also necessary to apply Chashi fertilizer appropriately. Generally, it is applied every 15 days, and the fertilizer still chooses phosphorus and potassium fertilizer, which can not only supplement nutrients, but also improve the cold resistance of the plant and help it better winter. 4. Precautions:

Camellia will go dormant in summer, and it is not advisable to fertilize it at this time. Although it will be semi-dormant in winter, the growth has not completely stopped, so in order for the plant to bloom better, it is still necessary to supplement fertilizer, but it should be combined with watering to reduce the concentration of fertilizer.

1. What kind of fertilizer to use.

1.Before flower bud differentiation, flower bud formation, growth and flowering, it is advisable to apply phosphate fertilizer or phosphorus-based compound fertilizer. 2.

Phosphate fertilizer and potassium fertilizer can be applied during the flowering period of tea trees, and phosphate fertilizer and potassium fertilizer can be buried in pots according to the amount to meet the nutrient needs of tea trees. Pay attention to the amount of fertilizer should not be too much to prevent fertilizer damage.

Second, how to fertilize.

1.Foliar fertilizer is applied. That is, rice vinegar, urea, potassium dihydrogen phosphate are mixed, diluted with water and sprayed.

At the same time, top dressing the roots to make the spring shoots flourish. However, the focus of Zheng Junai in the flowering period is to produce flower buds and promote flowering. At the same time, it is necessary to pay attention to the appropriate intake of other elements to promote budding pregnancy and ensure the quality of flowering.

2.When the spring shoots of the camellia grow vigorously and begin to lignify, the camellia plant will enter a semi-dormant state. Generally the time is very short.

It then gradually transitions to the growth phase, where flower buds form and begin to differentiate. At this time, you can ingest some phosphorus and potassium to reduce nitrogen intake, so as to help the plant conceive a large number of buds. This can not only prevent the steep branches of camellia, but also accelerate the differentiation of flower buds and promote the growth of buds.

1. Can you fertilize when flowering?

Camellia flowers cannot be fertilized when they are blooming, and applying fertilizer at this time can easily lead to flower drop, which will affect the firmness of the flowers. Fertilization should be done before flowering, and after the flowers have opened, pay attention to the light. It should be placed in a place with better lighting, basking in the sun more, so that it can better photosynthesize, which can play a role in fixing and preserving flowers, and can prolong the flowering time.

In addition, if you find that the number of flower buds is large, you should carry out bud thinning treatment. Cut off the bad buds and leave only the ones that are growing well, so that the nutrients are more concentrated.

Second, what fertilizer to apply for flowering.

It is preceded by the application of phosphate and potassium fertilizers to meet the demand and replenish the required nutrients. When fertilizing, you can choose foliar fertilizer, such as potassium dihydrogen phosphate, spray it on the foliar surface after mixing with water, and apply thin fertilizer frequently, preferably once every half month. It is also possible to apply fertilizer directly near the roots, and it is best to water a small amount after fertilization to speed up dilution, so that it is easier to be absorbed, which is conducive to flowering and growth in the later stage.

3. Precautions for flowering.

During its flowering period, it is necessary to pay attention to ventilation problems, whether it is maintained indoors or outdoors, to ensure good ventilation, otherwise it is easy to be infected with pests and diseases. If you find that there are diseased leaves and insect pests, you should spray the nucleus in time to avoid further deterioration.

Manifestation. Camellia fertilization too much will cause fertilizer damage. If the external nutrient level of the plant is too high, the internal water is lost, and the plant will slowly wither and die.

Once the camellia is fertilized too much, it will produce many symptoms, such as burning roots, rotten roots, etc. Some mild symptoms can still be improved, such as poor flowering, such as loss of buds or loss of buds, loss of buds, etc. As well as the phenomenon of deciduous yellow leaves, new leaves cannot grow, etc.

In general, if these symptoms are detected early, measures can be taken to promote the growth of plants. However, if the camellia has some difficult symptoms, such as the bud heart turns black, the new leaves turn yellow or even fall leaves, and the plant wilts and swims sleepy, it means that the fertilizer damage is serious. At this point, the plant may have difficulty recovering, and the leaves may fall off or the whole plant may wither.

This is very dangerous, so it is necessary to constantly observe the growth of camellia plants, and it is best to treat them in the early stage of fertilizer damage to prevent the plants from wilting and dying.

What to do. First of all, we must do a good job of prevention. When fertilizing, try to use organic liquid fertilizer.

The concentration of fertilizer should not be too high, and the hand mill should not apply fertilizer too frequently. The second is to change the pot and soil frequently. Camellias look like plants that have been growing for a year or two after growing for a while.

At this time, the soil in the pot is old soil, and it may be that too much fertilizer has accumulated. In addition, it is the phenomenon of fertilizer damage, that is, abnormal water accumulation in the flower pots. So it's best to change pots and soil often.

When changing pots, raise the pots high and try not to touch the ground. Finally, it was found that the camellia had fatty damage. It is best to repot immediately, or prune, re-cutting, or graft propagation to allow the camellia to grow again.

Watering: 1. Watering once a day in the spring and autumn growing season, and once in the morning and evening in summer, to maintain a certain air humidity.

2. When watering, water 1% to 1% ferrous sulfate every month and spray the leaves.

3. Camellia likes moist soil, and is afraid of stagnant water, so it should be removed in time to avoid the root system suffocating and rotting in the water on rainy days.

Fertilization: 1. In the fertilization process, apply enough liquid fertilizer, combined with changing pots to apply enough long-acting fertilizer, according to the size of the pot, apply 3 grams to 80 grams of rotted cake fertilizer powder or dried chicken and duck manure per pot, and mix well with the subsoil under the basin stool.

2. Increase the application of organic fertilizer according to the growth period of the plant. Except for the coldest and hottest times in winter and summer, apply 1 to 2 times a month to rot dry cake water.

3. In order to make the camellia grow better, in the vigorous period of camellia peanuts, it is necessary to carry out 1 to 2 times of extra-root fertilization every month, and spray the leaves with 1% to % potassium dihydrogen phosphate and 1% to 2% auxin.

4. The principle of fertilization: it should be light and not heavy, it should be light and not thick, it should be less and not more, and we must adhere to the method of thin fertilizer and frequent application, and do not apply fertilizer.

Water once a day during the spring growing season and once a day in the morning and evening in the summer.

Camellia fertilization is divided into two types: basal fertilizer and bai top dressing.

Generally, in late autumn and early spring, when transplanting, changing pots and subpotting pots, an appropriate amount of rotted base fertilizer can also be added at the same time.

It is best to use organic fertilizers for base fertilizer, such as soybean cake grains, fish bone meal and fermented and rotten fishy and poultry manure, which are dried, mashed and mixed with soil.

The ratio of soil to fertilizer is 9 to 1. Fertilization can be put on the bottom layer of the potting soil, and the top is covered with a shallow layer of fine soil, so that the root system of the camellia does not directly contact the fertile soil. The base fertilizer should not be too concentrated or too much, otherwise it will cause fertilizer damage.

After flowering, apply organic fertilizer or compound fertilizer in time, apply it once before the new shoots in spring, and generally manage it at other times, apply thin fertilizer frequently, but it is best to try nitrogen, phosphorus and potassium compound fertilizer before flowering. This keeps the tree vigorous.

Camellia is an evergreen broad-leaved shrub or small tree. During the vigorous growth period of camellia, fertilizer should be applied 1 to 2 times a month.

A1) In the process of fertilization, apply sufficient liquid fertilizer, combined with changing pots to apply enough long-acting fertilizer, according to the size of the pot, each pot to apply 3 grams to 80 grams of rotted cake fertilizer powder or dried chicken and duck manure, put it under the pot and mix well with the subsoil.

2) According to the growth period of the plant, increase the application of organic fertilizer. In addition to the coldest and hottest time in winter and summer, apply 1 to 2 times a month to decompose dry cake water, the fertilization method: the pot side soil is about 2 minutes, the liquid fertilizer is applied into the ditch that is covered with soil, to avoid odor.

You can also apply the rotted cake fertilizer powder to the edge of the pot and mix well with the potting soil to let the flowers absorb slowly.

3) Urban flower friends can go to the flower market to buy special fertilizer for flowers, which is both hygienic and safe.

4) In order to make the camellia grow better, in the vigorous growth period of camellia, it is necessary to carry out extra-root fertilization once to 2 times a month, and spray the leaves with potassium dihydrogen phosphate and 1% to 2% auxin.

5) The principle of fertilization: should be light and not heavy, should be light and not thick, should be less and not more, must adhere to the method of thin fertilizer diligently, especially do not apply fertilizer.
