You can prune the root system properly, and at the same time change to a large pot to avoid rotten roots.
-
You can change to a larger pot. This may be due to the fact that the pot is too small, leaving no room for the plant to grow.

Here is how to deal with the burning seedlings caused by fertilizer, when it is found that the seedlings are burned due to excessive fertilization, the first time to pour the pot and wash the roots, including the orchid leaves should also be rinsed clean.
<> it is best to leave the langan in the shade for a day to allow it to breathe some fresh air. Even if you buy it, the store will tell you to fertilize less, or persuade you to buy a bottle of nutrient solution, which will not burn the roots and grow well, but it is also difficult to deceive you into buying a bottle of nutrient solution. The stems and leaves of orchids are rotten, and the subject has already said that it is caused by excessive fertilizer, so at this time we must remove the fertilizer first, and then replant.
<> this is the approximate rescue process, to introduce in detail the stone hard granular planting material (such as planting stone, etc.) below, with 30% snake wood (snake wood is hollow and has good air permeability), rinse the fertilized orchid root with clean water, dry it and put it in a pot, put it in a cool and ventilated environment to rest, do not bask in the sun, reduce orchids due to photosynthesis The most direct is to replace the planting material and then clean it, and the surgical removal of serious conditions must be carried out in time to remove the infected reeds. When planting, we should choose a small orchid pot planting, if you use a large pot planting, the planting material will be more and thick, it is very tolerant that we can only do a good job of prevention, orchid pots and planting materials must be disinfected, and the planting materials will be dried again.
Use orchids as shallow as possible, the probability of stem rot will be less, the planting environment must be ventilated, the pot surface should not be too wet for a long time, and try to use more organic years in May - September is the peak period of disease.
It is mainly said that stem rot is caused by fungi, but no matter what kind of **, most of them have the inducement of high temperature, high humidity and lack of ventilation. The diseased seedlings are disinfected and sterilized, dried in a cool place and then re-potted. If the disease is serious, use a disinfection and sterilization knife to cut off all the leaves, sterilize and disinfect the remaining parts, dry them in a cool and ventilated place, and then put them on the pot again.
-
You can directly expose the original pot planting material to the sun to kill the germs, and then you can continue to use it.
-
It is very likely that this soil will be mixed with other soils or discarded, and it will be used if necessary, and discarded if it is not needed.
-
After the orchid is refined, the Yuanpeng data should be put into the soil to decay to provide nutrients for the soil.

Repotting: Reason: If the plant is not repotted all year round, but the plant keeps growing, this results in the pot not being able to hold as many roots as the roots of the plant stretch to the fullest, so its roots will grow out of the soil.
If it is not repotted in time, its roots will be intertwined and squeezed with each other, which will lead to some roots not getting fresh air and nutrients, and finally the problem of empty roots and rotten roots.
Measures: It is necessary to remove the pot and repot as soon as possible. Before depotting, you can reduce watering and make the potting soil drier so that it is easier to depot and prevent damage to the roots of the plant.
Then choose a larger pot, the new pot needs to be disinfected and rinsed in advance, and the plants will be planted after filling in the soil.
Change the planting material: Reason: If the roots of the orchid are breaking through the soil, then it may be because the planting material of the cultivated plant is not breathable. The roots of the plant have difficulty breathing at the bottom, so they will grow upwards on their own, breathing fresh air.
Measures: It is necessary to prepare a more permeable planting material for the plants as soon as possible, and the proportion of granular soil can be appropriately increased. After preparation, it should be soaked in disinfectant water and the planting material should be disinfected.
If the orchid is left with only roots left, then it may be difficult to survive. You can plant it first to ensure the air permeability of the substrate, and then water it without watering too much, so that the substrate remains slightly moist, and maintain it well for a while to see if it can be saved.

1.What to do if the orchid root grows out of the earth.
Repotting: Reason: If you don't repot all year round, but the plant keeps growing, this will cause the pot to not hold so many roots, and the plant's roots will not reach the maximum, so its roots will grow out and be unearthed.
If the pot is not changed in time, the root system will be intertwined and squeezed with each other, which will lead to some roots not getting fresh air and nutrients**, and the problem of empty roots and rotten roots will eventually appear. Measures: Flower pots need to be removed and replaced as soon as possible.
Before unpotting, you can reduce watering and let the soil in the pot dry out, which is not only easy to unpot, but also prevents damage to the roots of the plant. Then choose a larger pot. New pots need to be disinfected and rinsed in advance, and plants are planted after filling.
Change planting material: Reason: If the roots of the orchid break through the soil upwards, it may be because the material of the cultivated plant is not breathable.
If the plant's root system has difficulty breathing at the bottom, it will grow independently, breathing fresh air. Measures: Plant material with greater air permeability needs to be prepared as early as possible, and the proportion of granular soil can be appropriately increased.
After preparation, it should be soaked in disinfectant water, and the plant materials should be sterilized.
2.What to do if only the roots are left.
If the orchid is only middle-aged in its roots, it may be difficult to survive. You can plant it first to ensure the air permeability of the substrate, and then water, don't water too much, keep the substrate slightly wet, and you can maintain it well for a period of time to see if it can be saved.

The roots of the orchid grow out of the pot, which is "asking for help", hurry up to improve 2 points.
-
It may be the reason for the environment in which the orchid grows, and the foot leaves of the orchid are relatively hard. After budding, it will be inhibited and hindered by pots. So it will continue to extend beyond the soil.
-
It is mainly because it has a certain relationship with the growth environment of the orchid plant and the granularity of the cultivation material.
-
It may be that the volume of the pot is relatively small, and the rhizome of the plant is more developed, so it grows out of the pot.
-
The rotten roots are cut off, disinfected, then soaked in a rooting agent solution, and finally soiled.
Analysis of the causes and solutions of empty roots in orchids.
Long-term lack of water causes orchids to empty roots.
Solution: Watering should be sufficient, and "half water" should be eliminated. Watering orchids is a basic skill of raising orchids, and it is also a difficult problem to master.
The so-called "half-cut water" refers to the moderate moisture of the upper half of the planting material in the orchid pot, while the lower part is dry. This is the crux of Langen's hollow roots. There are two ways to put an end to this phenomenon:
First, watering the orchid should be repeated several times, and do not stop watering as soon as you see the water running at the bottom of the orchid pot. In fact, sometimes if you water the orchid a little bit, there will be water flowing out from the bottom of the orchid pot, but the internal planting material is dry. Therefore, it is necessary to repeatedly water several times to ensure that the planting material is fully moistened.
The second is to use the "sitting pot" (soaking pot) method for watering. That is, the orchid pot is placed in a container containing water, so that the surface height of the potting soil is basically the same as the height of the water surface in the container, so that the water slowly rises from the bottom of the pot to fully moisten the planting material. This method of watering is most uniform and sufficient.
The planting material is not in good contact with the roots, and the lack of nutrients leads to the empty roots of the orchid.
Solution: The planting material should be mixed evenly to ensure that the potting soil is in full contact with the root. Gu Puyun "does not touch the soil, its roots are empty".
It's really a matter of experience. Practice has proved that the contact between the potting soil and the root is not sufficient, and after a long time, the root will lose water in the air, and the phenomenon of empty roots will appear. Based on this, this requires Yilan people to fully mix the planting material when planting orchids, fill in the order of large, medium and small particles in turn, and pat the pot wall to make the pot soil fully contact with the orchid root after the potting; Further increase the contact surface between orchid root and planting material, and then incorporate it into daily management, if properly managed, it can effectively avoid the occurrence of orchid hollow roots.
The planting material is not breathable, causing the roots to rot and then empty the roots.
1. Potassium permanganate treatment. Soak the planting material with a concentration of one thousandth for more than 10 minutes. Potassium permanganate is a strong oxidant, and its purple liquid is too concentrated to burn the orchid plant, so it should be used with caution. >>>More
The root system of the large-flowered orchid is very developed, and most of the commercial orchids in the general orchid garden are 4-year-old seedlings, in order not to affect the growth of the orchid seedlings in these 4 years, they will not prune the roots, but will only constantly change the pot. >>>More
This process is necessary because most of the empty roots have lost the necessity of their existence. Keeping them in pots will only deteriorate the potting soil environment due to decay, and repairing them in time can give the new roots a better environment. >>>More
