Orchids have just been repotted, when can they be fertilized?

First of all, we have to understand that orchid repotting is different from other repotting, repotting is the least damage to the root system, or almost no damage, and the pot is served soon after turning the pot.

If it is rotten roots to change pots, or burst pots and branches, at this time it is necessary to destroy the root system, so the potting period will be very long, so generally rotten roots, branches, etc.

When is it good to fertilize orchids after repotting? Three lessons have been made clear

1. Weak seedlings and diseased seedlings are repotted.

As we said just now, turning over the pot does not hurt the roots, but after turning the pot, how to fertilize the weak and diseased seedlings after turning the pot? My suggestion is not to fertilize, weak seedlings and diseased seedlings are not to fertilize, but you can use thin foliar fertilizer to fertilize, the concentration is controlled at more than 2000 times, and the leaves are thick and green, and then fertilizer is added to the potting soil after the seedlings are strong, and it is not recommended to supplement the base fertilizer when potting.

2. Fertilize before turning pots.

If you are worried that fertilization will lead to root dehydration after the orchid is repotted, and you are afraid that the root system will burn seedlings, you can fertilize before repotting, and you can water the nutrients about a week before repotting, so that the root system can absorb enough and then turn the pot, and then turn the pot after the potting, because the nutrition is enough, the leaf growth is good, and the better the leaves, then the root will be much faster again, and of course, the potting is also very fast.

3. Fertilize after turning the pot.

If the seedling condition of the orchid is very good, it is because the pot is too small and turned over because of the burst of roots, such as from a few seedlings to a dozen or twenty seedlings, at this time the root system is too much, and the nutrition must be insufficient.

Is it good for orchids to be repotted often?

In fact, orchids are not afraid of repotting, and there are many benefits of repotting, and repotting can gain experience in many aspects.

1. The wetness of potting soil planting material is judged to be watering frequency.

After turning the pot, you can check the wetness of the potting soil planting, and judge the frequency of watering through the wetness of the potting soil, which is a good way to determine the watering frequency, for example, when we pot the orchid, if it is still drying the roots, we can first pot the potting soil planting, and then pour out the potting soil planting material to check the moisture of the potting soil, and then judge the watering frequency.

2. Root development.

We can also check the root development of orchids by turning over the pot of orchids, such as poor root system, no new root system emerges, at this time you can adjust the maintenance method according to the situation of the root system, the potting soil planting material is too wet and heavy to adjust the planting material, watering too often on watering, and replenishing nutrition if the nutrition is insufficient.

3. Composition of potting soil planting material.

There are many components of orchid potting soil planting, the ratio of orchid planting material suitable for yourself is not the same, we refer to the potting soil planting material formula on the Internet, and find that the growth is not good after turning the pot, we can adjust the planting material formula appropriately and change the maintenance method.

After turning the pot, don't rush to apply fertilizer. Orchids are shade-raised, and after the orchids are potted, thin fertilizer or foliar fertilizer is applied. Because orchids grow slowly during potting, fertilization will increase the burden on orchids.

There is no fixed period for how long the orchid can be fertilized when it is just potted, and it should be determined according to its potting situation, and the fertilizer can be applied after the pot is completely served. After taking the pot, it will show that it will grow a new crystal head, which means that it can absorb nutrients normally and adapt to the new potting soil environment. Or the weeds are shed very slowly, the leaves of the new seedlings become very green and shiny, and the new shoots are very vibrant.

Fertilizing orchids usually refers to top dressing, because base fertilizer will be applied when potting, and chemical fertilizers, organic fertilizers or foliar fertilizers can be applied after potting in the later stage. And there are many ways to apply fertilizer, but no matter how you apply it, you should pay attention to two points.

First, if the fertilizer is applied to ensure that the proportion is balanced, the fertilizer can not be too single, and the amount of fertilizer cannot be excessive, and it must be carried out in strict accordance with the instructions. Second, if the organic fertilizer is applied, it must be fully fermented and sterilized thoroughly, otherwise a large amount of heat will be released after application, burn the root system, and may also multiply a large number of bacteria, affecting the growth of plants.

The fertilization method of orchids is very important, if you do not master the reasonable fertilization methods, unreasonable fertilization of orchids will often cause fertilizer damage, resulting in root rot and even death of orchids. So, when is the best time to fertilize orchids when they are just potted? On this issue, it is as follows.

In the past, when I raised orchids, due to the lack of experience and technology in raising orchids, I thought that whether the growth of orchids was lush or not was related to the amount of fertilizer, so I often made the mistake of unreasonable fertilization, and finally not only did not raise orchids well, but caused fertilizer damage, and the orchids were lost. The maintenance of orchids in the potting period is very important, if it is not properly maintained, it is difficult to potting and feeding, especially fertilization, special attention should be paid! The following points should be noted.

As we all know, orchids need to be dried and pruned when they are potted, and some empty and rotten roots must be pruned off before they are potted and planted. Orchids that have just been potted have a potting period, and the potting period is long and short, the short one month can be potted, and the long one is about half a year. Only after the orchid is potted will it grow new roots and absorb fertilizers and nutrients.

Before the orchid has not been potted and has not produced new roots, its old roots are not absorbed by fertilizer, if during this period, the roots of the orchid are fertilized, in the case of the orchid roots can not be absorbed, often form fertilizer damage, resulting in rotten roots of orchids. Therefore, orchid friends with planting experience rarely fertilize the roots of orchids in the first year of potting, and in the second year, after the roots are strong, they will apply thin fertilizer frequently.

The above is that when the orchid is just potted, it cannot fertilize the roots of the orchid, that is, it cannot be watered and fertilized, but it does not mean that it cannot be fertilized. Since the roots of freshly potted orchids cannot be fertilized, foliar fertilizer should be applied instead. As we all know, orchid leaves have the effect of absorbing nutrients, in order to ensure that the orchid just potted has enough nutrients, we can use potassium dihydrogen phosphate 1500 times liquid to spray a foliar fertilizer to the orchid just potted, which not only adds nutrients to the orchid, but also does not cause fertilizer damage, and will make the orchid plant eat the pot faster.

Figure 4 is the old seedlings that I potted this year, I thought the seedlings were too old and would not germinate, and only sprayed foliar fertilizer once after potting, and now a strong bud has been issued, just in case, wait for next year to apply root fertilizer.

Orchid can not be fertilized during the flowering period, at this time fertilization will cause its flowers to wither in advance, to fertilize orchids to master the principle of thin fertilizer diligently, generally in its growth period to fertilize, about 20 days after flowering can also be fertilized, orchid flowering period should also be reasonable watering, light should not be too strong, the growth environment also requires warm ventilation.

1. Fertilizer cannot be applied

The growth of orchids needs sufficient nutrients, but when it blooms, it can not be fertilized, at this time, fertilization will cause its buds to wither, and the flowers will wither in advance, so that the flowering time of orchids will be greatly shortened, and in serious cases, it will also lead to fertilizer damage to plants.

2. The principle of fertilization

When fertilizing orchids, we must master the principle of thin fertilizer diligently, and must not apply raw fertilizer or thick fertilizer to it, for example, when its leaf buds grow, we can apply light fertilizer water several times to it, spring and autumn and about 20 days after it flowers, you can apply thin fertilizer every 2-3 weeks.

3. Reasonable watering

When the orchid is in bloom, it also needs to be watered reasonably, this time it is necessary to water less, it is best to observe that the soil is dry and then watered, and the amount of water should not be too much, when watering should be slowly watered along the edge of the pot, and the water must not be splashed on its flowers and leaves.

4. Light and temperature conditions

When flowering, it is also necessary to let it have a suitable light temperature, sunshine maintenance in a semi-shaded environment, so that it has an appropriate amount of scattered light irradiation, must not be exposed to strong light, but also need to do a good job of temperature control and ventilation measures, to avoid letting it in a stuffy environment, otherwise the plant is easy to grow poorly.

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.

Extended information: In the process of orchid growth, the orchid leaves should be pruned frequently, and the old leaves should be cut off in time when they are yellow, so as to facilitate ventilation, and the tips of some leaves should also be cut off. In particular, leaves with pests and diseases should be removed in time to avoid infection.

The safest way is to cut off the flower stems in time after the flowers, and the safest way is to cut off the flower stems at two or three centimeters above the pot surface for the first time, and after a period of time, the remaining old stems will be cut off after withering, so as to prevent new wound infection.

Before pruning, be sure to disinfect the scissors with liquid or alcohol, which can be disinfected every time you cut to avoid wound infection.

1. All living animals and plants need nutrition, animal nutrition is food, plant nutrition is fertilizer, including orchids need fertilizer, I fertilize orchids when applying organic farm fertilizer and downhill humus when dividing or turning pots, accounting for one-tenth of the total planting material.

2. Orchids are fertilized, with different nitrogen, phosphorus and potassium content in different growth periods, and chemical fertilizers and organic fertilizers alternate.

3. 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!

4. All animals need to eat food, and if they are not full or eat well, they will affect their health, and they will starve to death if they do not eat; 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.

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

6. The soil of the orchid must be fertile, otherwise it will not bloom, but it must be applied thin fertilizer every time, and if it is not enough, it will be applied again after the interval time, that is"Apply thin fertilizer and more" 。
