What fertilizer should I put on orchids and how much? Refuse to excerpt the post on the web, thank y

This question is a bit difficult, because what fertilizer to water and how much to water depends on the growing season and growth of the orchid, it is best to apply different fertilizers, but do not apply all fertilizers to prevent the orchid plant from being harmed.

Some advice based on years of experience:

1.Fertilization can be left out during the dormant or weak growth period.

2.At the seedling stage, nitrogen fertilizer can be used as the main fertilizer to promote the rapid growth of orchid seedlings, grass and roots; When the new seedlings grow to about 5-6 cm, phosphorus and potassium fertilizers can be used as the main fertilizer to promote the thick and strong seedlings. Improve the immunity of orchid seedlings against diseases and insect pests.

3.Large seedlings and strong grass are vigorous for a long time, and nitrogen fertilizer should be applied frequently, which can be done once a week.

4.For rejuvenated grass, the number of times should be appropriately reduced, half a month or longer. Weak grasses, rootless grasses, and leafless bulbs should definitely be cultivated and should not be fertilized.

5.This is important. Fertilization should be applied on cloudy days or when the temperature drops in the evening, and then rehydrated the next morning, commonly known as returning water. This flushes away the surplus and fertilizer, which is conducive to the growth of orchids.

6.Fertilization is rather light than thick, and 200-300 times of fertilizer can be used to irrigate the roots with thin fertilizer.

Don't forget! 1.Thin fertilizer 2Return the water.

I have orchids at home.

Usually 15 days to pour a glass of water.

Fertilize once a month.

Special orchid fertilizers can be used.

They are sold at the flower shop.

But. It depends on the weather.

Hope it can help you a little.

The biggest problem in family orchid farming is planting material, generally using sandy soil and pond mud (inferior ones), coupled with water every day, sediment and water, and the pot is not breathable, the result is that the roots rot and leaves are rotten, and eventually die. Any of the following three types can be used to solve the planting problem.

1. Use all bricks, use chestnut-sized bricks at the bottom of the pot 1 3 high, and use peanut-sized bricks after placing the orchid plant.

2. Use 30 clean coarse river sand, add 70 fresh wood bran, and use chestnut-sized bricks at the bottom of the pot 1 3 high.

3. The bottom of the pot 1 3 high with chestnut-sized bricks, after placing the orchid plant, use the Emeishan fairy soil with medium and small particles. Beginner orchids, should not use large pots, generally use 10 cm to 20 cm diameter of the cylinder pot or horn pot, each pot can plant three to five plants. In addition to the use of wood chaff, the orchid is planted with bricks or Emeishan fairy soil, even if it is drenched every day, the water will also pour out, the pot does not accumulate water, there is both humidity and air, the orchid root can grow happily, and the orchid plant is also healthy.

When using wood chaff seeds, care should be taken not to let the water damage the roots.

Raising orchids on the family balcony should be protected from exposure to the sun, strong winds, and frost. In this kind of weather, you have to put the orchid down on the balcony. It's okay to put it on the balcony base to bask in some sunlight. If there is no sunlight, it will not bloom.

For insect and disease control, pesticides can be used, diluted according to the proportion mentioned in the instructions, and the orchid leaves can be brushed with a new brush or directly drenched in the potion. The dilution ratio must be accurate, too concentrated and too dilute will affect the efficacy of the drug.

If you want to put fertilizer, you can use compound fertilizer granules or peanut bran powder to put on the edge of the pot, three to five grams each time, not too much, and should not be placed near the orchid head or orchid buds. Or buy orchid liquid fertilizer to spray the foliage.

Beginners should not buy high-end varieties of orchids rashly, so as not to suffer losses due to planting death. In the first year or two, plant ordinary varieties of orchids, three yuan a plant or several, ordinary varieties of orchids such as flowering generally have a fragrance, sometimes it will be very fragrant, Ye Zi also has a certain ornamental value, plant live and gain experience and then plant mid-range varieties of orchids, to be completely sure of the high-end varieties of orchids, so as to suffer less economic losses.

Do you need to fertilize orchids at home What fertilizer to apply to listen to what the little brother of orchid raising.

Orchids require nitrogen, phosphorus, potassium and trace elements.

Buy a little potassium dihydrogen phosphate and spray it, the orchid grows wildly, and all kinds of elements are complete.

It is also possible to spray pills aspirin, and orchids are also vigorous.

Nitrogen, phosphate, potash, nothing special.

The fertilizers suitable for orchids are: fully decomposed pulp residue water, chicken, dog, goose feather soup, grass ash water, grass juice, etc. Some people sprayed the foliage with 5 1000 potassium dihydrogen phosphate (newly planted orchids can also be sprayed to help rooting), or watered the orchids with fishy water and fermented rice water, all of which received good results.

The timing of orchid fertilization should generally adhere to the "four no-applications": that is, the newly planted orchids should not be applied (within half a year), not applied in cold days, not applied in Futian, and not applied at noon. It is best to apply fertilizer after 5 p.m., and water it once in the morning of the next day (if it is a foliar spray, it should be sprayed with water the next day).

The principle of orchid fertilization is: rather light than thick; Try a few pots first, and then the whole garden; First give the general, then the treasure.

There are two types of orchid fertilization methods, one is: root fertilization and the other is: foliar fertilization.

The roots and leaves of orchids can absorb and use fertilizer, foliar fertilization is a supplement to root fertilization, fertilizer effect is fast, immediate, can not be relied on or used for a long time, should be used in conjunction with root fertilization. Root fertilization is divided into two situations: the one that is directly mixed with organic matter or organic fertilizer in the planting material is called "base fertilizer", and the one that is applied from the surface of the planting material is called "top dressing".

The base fertilizer should not be too much, in order to avoid fertilizer heat injury to the roots or make the root bark black, top dressing is a supplement or adjustment of the insufficient fertilizer in the pot. Root fertilizer can be used bark blocks, leaves, peat, coconut shells, chaff, peanut shells and other organic matter, these organic matter needs to be fermented before use, it is best to cook at high temperature to kill germs and insect eggs, the ability of organic matter to absorb water after cooking will also be enhanced, and the speed of organic matter release will also become faster. You can also directly use organic fertilizers such as cake fertilizer, cow dung, sheep manure, etc.

It can also be used for chemical fertilizers such as urea on the surface of the planting material, long-term coated slow-release fertilizer, such as Aolu, Haokangduo, magic fertilizer, etc. The leaves can be diluted with organic fertilizer with water, or the leaves can be sprayed directly with chemical foliar fertilizers, such as potassium dihydrogen phosphate, Huabao, Xishuo, etc.

When fertilizing orchids, you can mix fertilizer directly in the soil, or spray foliar fertilizer, which can supplement nutrients. The frequency is about once a half month, and the principle of thin fertilizer application is carried out frequently. Fertilizer can be used rotten farmhouse manure or compost, and phosphorus and potassium compound fertilizer can be used when fertilizing in the growing season.

If the roots of the plant are not healthy in winter, then do not fertilize it first, because the plant itself is problematic, and if you fertilize it again, the roots of the plant will suffer a certain burden. If the temperature of the breeding environment is too low, it must not be fertilized. In addition, when it is too cold, you should also pay attention to keep warm to avoid frostbite on the plants.

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.

1. Special fertilizer: There are special fertilizers for orchids on the market. If you do not know how to prepare fertilizer, it is recommended to buy special fertilizer directly for orchid application. The special fertilizer for orchids is specially designed for orchids, which is in line with the growth habits of orchids, and is suitable for fertilizing orchids.

2. Homemade fertilizer: If you don't want to buy special fertilizer, you can also make your own fertilizer. Mash fruit skins, fish bones and other substances into a bottle, add some water, and let the water surface reach about three-quarters of the height of the bottle.

Then screw the cap and put it in a warm place to ferment. After about 2-3 months, the fermentation is complete and they can be used as fertilizer.

1. Growth period: the growing season of orchids in spring and summer. At this time, it is recommended to apply 1-2 times a month to it. When fertilizing, the fertilizer should be diluted with water before applying it to the plant, so as not to burn the root system of the plant with too concentrated fertilizer.

2. Summer: Plants will also grow in summer. However, because of the high temperature, it does not grow very quickly, so the frequency of fertilization should be reduced. Generally, fertilization every 2-3 months is fine. It is best to apply slow-release fertilizer.

3. Winter: In winter, the temperature is very low, orchids grow very slowly, need less nutrients, and do not need to fertilize. Wait for the temperature to rise in the spring of the next year, and then fertilize it.

For orchids, there are many fertilizers available, and some are specifically for orchids, and the effect is better. However, some substances are inconspicuous and do not cost too much money, and the effect is good.

1. Shiitake mushroom soil: It is acidic and suitable for orchids. The nutrients contained in it are relatively moderate, and the fertilizer effect time is long.

Moreover, it can be used both as a fertilizer and as a substrate. Compared with other substrates, it has a looser texture, and has better drainage and air permeability. It can be mixed with other substrates as culture soil, and its volume can account for 20 to 30 percent.

2. Chuaf charcoal: This substance contains more potassium, and after application, it can make the soil more loose, and it can also appropriately increase the temperature of the soil. However, it is originally alkaline.

However, after a month or two of sun exposure, it can be neutral. It can be treated before use.

3. Bone char: It is mainly used as a phosphate fertilizer, because it is particularly rich in phosphorus. And, as a fertilizer, it works quickly and can last for a long time.
