How to fertilize orchid balcony and what are the precautions?

When we raise orchids on the balcony, we should pay attention to the principle of preferring shortage to abundance, and preferring scarcity to abundance.

Orchids that have just been planted for 1 or 2 years, and the root system has not yet grown, do not fertilize. If the growth period is more than 1 2 years, you can apply a well-rotted liquid fertilizer in about 20 days in June and July. By August and September, liquid fertilizer is applied once every 15 20 days.

In winter, fertilization is stopped.

Fertilizer once a month, in the process of fertilization, we must dilute the fertilizer, otherwise it is easy to burn its roots, and we usually have to water and fertilize it more.

I think I can add some beer water to raise orchids, so that the plants are not easily damaged.

If you often pour potassium permanganate into the water and pour the mixture into the orchid, then the orchid will grow very well and will not get pests and diseases.

You can use any water, as long as it is ordinary clean water, you can use tap water, you can also use rainwater.

1. The time of orchid fertilization should be carried out in the growing season of orchids, the physiological activity of orchids is very slow or stop moving, at this time there is no need for fertilization, generally in spring and autumn, the temperature of these two seasons is between 20-30, suitable for fertilization, summer fertilization needs to be carried out in an environment with a temperature lower than 30, that is, the timing of fertilization of orchids mainly depends on the temperature.

2. Use nitrogen-containing potassium fertilizers in the spring and autumn orchid leaf growth seasons, such as urea, nitrogen fertilizer can make the cells of orchids expand, promote the growth of orchid stems and leaves, make the leaves lush, the leaf color is dark green, potassium fertilizer can improve the lodging resistance of orchids, when the temperature is higher than 20, you can start to use fertilizers containing nitrogen and potassium, use them every 7-10 days, use them 2-3 times in a row, and use fertilizers containing phosphorus and potassium elements 15-30 days before the orchid flowering period, such as potassium dihydrogen phosphate, It is also used once every 7-10 days, 2-3 times in a row, fertilization should be carried out in sunny weather, and the temperature is higher than 30 Do not fertilize.

3. The fertilizer selection of orchids is still based on nitrogen, phosphorus and potassium three major elements, they are divided into organic fertilizer, inorganic fertilizer and biological fertilizer, we commonly use organic fertilizer and inorganic fertilizer, organic fertilizer is the product of decay and fermentation of animal and plant corpses, organic fertilizer is mainly synthetic chemical fertilizer, organic fertilizer is more mild than the release rate of chemical fertilizer, it will be safer, most of the chemical fertilizers are fast-acting fertilizers, which can be quickly absorbed and utilized by orchids after use, and are easy to produce fertilizer damage if they are not properly treated. You can also choose safe and efficient coated long-term slow-release fertilizer, which is relatively high-tech and will be released slowly with each watering.

4. Orchid fertilization precautions: organic fertilizer must be fully fermented, otherwise it will burn the roots, inorganic fertilizer should be kept away from the roots, too close will seriously burn the orchid plant, whether it is organic fertilizer or inorganic fertilizer, it needs to be diluted high times when used, so as not to have problems. Foliar fertilizer can only be used as a supplement to root fertilizer, and only foliar fertilizer can be used for a long time, and fertilizer can not be applied to old seedlings, weak seedlings and diseased seedlings.

<>1, pay attention to shade, orchid grass likes shade, in the orchid to consider the shade of orchid, you can plant some climbing plants on the balcony, such as creepers, or triangular plum, etc., can greatly reduce the illumination, but also beautify the balcony to hold the lead environment, both of both. In addition, if the balcony sits north and faces south, it is necessary to prevent the west from the sun. The sun in summer is particularly strong, the heat is poisonous, and the bluegrass is the most taboo, so it is necessary to avoid the west as much as possible, and you can put a shade net on the west side; Or put a pot of two or three meters high evergreen plants such as orange trees, osmanthus trees, etc. on the west side of the balcony, which has a good shading effect.

2. Increase air humidity, balcony air flow is large, high temperature, water evaporation is fast, bluegrass growth needs a certain amount of humid air, especially in summer to increase humidity. Put a few buckets on the balcony, or sprinkle more water on the floor, and if possible, you can install a humidifier.

3. Keep warm and cool down, the temperature of the balcony is relatively low in winter, and it is easy to be harmed by the northwest wind and frost, especially pay attention to Hanlan, Molan, and Jianlan are more afraid of cold. If you spend the winter on the balcony, you should cover the balcony with a transparent agricultural film, which can protect against frost. In the summer, it is necessary to consider cooling down, install wall fans on the wall to enhance air flow, and if you install a sprayer, it will be more effective.

4. Sterilization and disinfection, the balcony is exposed, the orchid grass is easy to be infected by outdoor germs, it is necessary to sterilize and disinfect frequently, and we must pay attention to the sterilization of orchid leaves; Second, we should pay attention to the disinfection of potting soil. Orchid leaf sterilization uses systemic pesticides, which can prevent the stomata of orchid leaves from being blocked; Potting soil disinfection can be done by using sodium disulfonate, thiophanate-methyl, chloramphenicol, and potassium permanganate to irrigate the roots thoroughly.

Orchids mainly need to be fertilized when they are growing fast, the specific time is spring and autumn, and summer is not suitable for fertilization because the temperature is too high. In winter, the plants do not grow at all, so there is little need for fertilizer.

Bud-promoting fertilizer is applied in spring, and the fertilizer applied during this season is the most important and has an impact on the growth state throughout the year. In autumn, it is a different fertilizer, which is used to promote budding and strengthen seedlings. If you apply fertilizer at the right time, the orchid will grow well, and the flowers will be more numerous and better.

The most important thing in fertilization is the concentration, it does not like too concentrated fertilizer, it should be diluted with water, if it is foliar fertilizer, pay attention to the part sprayed to, and should spray more on the back.

2. All animals need to eat food, and if they don't eat enough, they will affect their health, and if they don't eat, they will starve to death; All plants, including orchids, need fertilizer, in order to raise orchids well, they must be fertilized, poor fertilization, insufficient fertilization will affect the growth of orchids, and if you don't fertilize at all, orchids will starve to death. Therefore, fertilizer is the basis for the survival of all plants and the food of all plants. Therefore, orchids must be fertilized, and they must be fertilized well and sufficiently fertilized.

Fertilizer is divided into three categories, namely organic fertilizer, inorganic fertilizer and indirect fertilizer, its types are different, the nature is different, the role is not the same, the variety is complex, the variety is numerous, up to thousands of kinds, there are simple fertilizers, compound fertilizers, compound fertilizers, full-effect fertilizers and special fertilizers, among which the special fertilizer effect is the best. I recommend the use of Shuguang brand orchid fertilizer, not only good effect, no toxicity, no effect, but also easy to use, hygienic. Welcome to my blog, which may inspire and help you.

3. I like foliar fertilization, generally applied at night, spray the orchid leaves before drying, and then spray with dihydromethyl phosphate mixed urea after drying, once a week, the effect is very good, and the idea is thin fertilizer

1. Compound fertilizer three times a year! A pot of orchids is a dime a year! Occasionally, you can mix ten urea grains with a bottle of mineral water and spray leaves, because the Qing Dynasty did not have urea, let alone magic fertilizer, good Kangduo, orchids are still native and multi-flowered, don't deliberately ask for it!

1. According to the growth of orchids, it is also necessary to check the foliar surface to see if there are any diseases and insects in the foliar fertilization.

2. Orchids begin to germinate in spring and summer, and fertilizing the roots of orchids can promote the rapid growth of new shoots.

3. The fertilizer used in orchids is mainly nitrogen, which can be sprayed with some organic liquid fertilizer, and the orchid enters the reproductive growth period in autumn, and it is best to apply phosphorus and potassium fertilizer.

4. In late autumn and early winter, it is necessary to apply cross-winter fertilizer, solid fertilizer can be applied, and some liquid fertilizer with a large concentration can not only enhance the cold resistance of plants, but also lay a good foundation for the growth of the next year.

5. Germination fertilizer can promote the growth of new shoots, generally used in spring, when fertilizing the foliar surface, it must not be in the morning, but in the evening or in a dark place.

Orchids can only be fertilized with thin fertilizer, and fully decomposed thin cake fertilizer water should be applied 1-2 times a month during the vigorous growth period. Since orchids are fleshy roots, do not apply unrotted fertilizers to avoid burning the roots. Before each fertilization, the water should be controlled for 1-2 days, and then the potting soil should be slightly dry before application, and the water should be watered once in the morning on the second day after application, in case the fertilizer enters the rainy season, how to fertilize the orchid in this season?

Fertilization is generally not recommended after mid-June, why?

Because we should have applied all the fertilizer by the beginning of June. So, if you have delayed fertilization in the past for various reasons, how to do it in June? In other places, the temperature does not reach 35, and this is because of the size of our country.

It is precisely because of the different temperatures in different places that the growth of orchids in different places is also different. Therefore, when it comes to orchid fertilization in June, we can easily produce fertilizer damage according to the local temperature and the fact that the orchid grows and the fruit cannot accept it for a while.

So I use urea mostly for hole application, put about 10 grains along the wall of each pot, and then cooperate with watering to dissolve. Note that the soil must be covered after the acupuncture is applied, otherwise urea dissolution will produce biuret, which is a chemical that has a certain need for potassium and three elements of nutrients for plants, but microelements such as calcium, iron, zinc, magnesium, copper, boron, molybdenum, etc., are also essential. Fertilizers commonly used for foliar spraying of orchids, including urea, ammonium sulfate, and ammonium nitrate, contain nitrogen; phosphorus-containing superphosphate, potassium phosphate, potassium dihydrogen phosphate; Potassium-containing potassium nitrate and potassium chloride have been potted old seedlings and strong seedlings can be appropriately applied with thin fertilizer, such as:

Fertilization is prohibited for small seedlings and weak seedlings. After August and September, you can spray once a week.

Chunlan, Huilan, Jianlan, Molan, and Hanlan, etc., are commonly referred to"Chinese orchid"。Chinese orchid does not have eye-catching showiness, no huge flowers and leaves, but has a simple and quiet, elegant and noble temperament, and is loved by the majority of flower friends. Many people like to maintain a few pots at home.

The first point of fertilization is best to use that special fertilizer is particularly good, the second point of fertilization should pay attention to the whole fertilizer of this amount is very important, the third point should be regular watering.

Fertilization should be done on time, as fertilization allows plants to grow better, and fertilization on time allows for a more balanced distribution of nutrients.

I think we should clean up the environment before planting some orchids. Then when fertilizing, you should go to fertilizer frequently. In this way, the orchid will grow very well.
