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.

Many flower lovers have just bought orchids in less than a month after being potted. The reason is that they didn't do anything more. Because most of the orchids we just bought are cultivated in greenhouses, and the orchids grown in greenhouses are often sterilized and disinfected, so there will be no problem next to the good sail cavity.
So the orchid we just bought must be sterilized and sterilized. First of all, after buying it, if the acorn does not have a good pot, we will first use the fungicide penicillin and add water at a ratio of 1:1000.
Then, we will put the whole orchid in and soak it for 15 minutes. At the same time, we will pour it again after putting the pot on it. Water all of its soil thoroughly and let it completely remove harmful bacteria from the soil.
In this case, a pot will be placed under the round reed, which is not easy to cause problems in the new environment and ensures its healthy growth in the new environment. So that's why, many friends who raise new orchids always can't raise the orchids they buy back, and they die soon after they are put in the pot. Then, one more thing to keep in mind is that after placing the pot, do not fertilize and do not water for three months.

Orchids are a very popular ornamental flower, but many people often encounter the problem of rotting sprouts in the process of caring for orchids. Bud rot not only affects the beauty of orchids, but can also cause pests and diseases. So, how to deal with the problem of orchid sprout rot?
First, we need to understand the causes of orchid sprout rot. The main cause of orchid sprout rot is due to overwatering or the root system is not airy. Therefore, the method of dealing with the rot of orchid sprouts is obvious:
Watering should be controlled and the roots of the orchid should be ventilated.
Specifically, there are several approaches that can be taken:
1.Controlled watering: Orchids are plants that are adapted to arid environments, and they do not have a high need for water.
Therefore, when maintaining orchids, you should pay attention to the amount and frequency of watering, and do not overwater. In general, orchids should be watered once a week to avoid water accumulation at the bottom of the pot.
2.Improve ventilation conditions: The root system of orchids needs to be ventilated, otherwise it is easy to cause root rot.
Therefore, the orchid can be placed in a well-ventilated and sunny place, or the cultivation medium and potting soil of the orchid can be adjusted appropriately when caring for the orchid to improve its ventilation.
3.Apply the right nutrients: Orchids need the right amount of nutrients to maintain their growth and flowering during their growth.
Therefore, some nutrient-rich fertilizers, such as organic fertilizers, compound fertilizers, etc., can be appropriately applied during the long-term relationship of orchid flowers. However, it is necessary to pay attention to controlling the amount and frequency of fertilizer and avoid over-fertilization.
In conclusion, orchid sprout rot is a common problem, but as long as it is treated according to its cause, it can be effectively avoided and solved. The growth of orchids requires patience and concentration, and only after careful maintenance can orchids grow more beautiful and healthy.

1. Strengthen ventilation: Put the orchid sprouts in a ventilated place. 2. Reasonable fertilization
Fertilization is applied by burying and leaf spraying to avoid fertilizer contamination of new shoots. 3. Watering correctly: water the sprouts with a fine stream of water or a dense small sprinkler to avoid the sprouts from breathing due to stagnant water.
4. Pest control: spray imidacloprid every 2-3 days, and spray twice.
1. Strengthen ventilation
Orchid cultivation in the environment of not ventilated, high humidity, easy to cause the breeding of soft rot bacteria, planting orchids can use pots with drainage holes, the soil is loose, strong air permeability is the best, maintenance should be placed in a place with air circulation.
2. Reasonable fertilization
The new shoots of orchids are afraid of fertilizer, once the fertilizer water wets the bud head, it will lead to rot, so the safest way to apply fertilizer is buried and leaf spraying, which can effectively avoid fertilizer dripping onto the new shoots.
3. Water properly
If the water flow is too rapid when watering, it will rush into the center of the orchid sprout, causing the sprout to breathe poorly and thus rot, so when watering the sprout, it is necessary to use a thin stream of water or a small nozzle with a dense spray eye, and to water before 7 o'clock in the morning, so as to promote the evaporation of the water left in the heart of the sprout leaf as soon as possible.
4. Pest control
Encountering insect pests will also lead to the decay of orchid shoots, for insect pests under the soil, generally use root irrigation to remove pesticides, if you find traces of pests on orchid leaves, you can use imidacloprid after mixing water for root irrigation, irrigate the roots once every 2-3 days, use twice.

In the world of raising orchids, it is also a problem that orchid friends will encounter, and it is something that often happens to novices in orchid raising.
1. There are many reasons for the rotten sprouts of orchids; The main problem is that there is too much water mist sprayed. The second is that the spraying of foliar thin fertilizer is too heavy (such as; potassium dibasic phosphate). Third, spraying insecticidal and fungicidal drugs is too concentrated (such as; carbendazim, etc.).
Fourth, the orchid is watered too much and too often. Fifth, the environment is not ventilated. Sixth, the planting material is not breathable and other reasons.
Second, there are two ways to rot new shoots in orchids. 1. "Half poured pot"; It is to pour one-third or half of the planting material in the orchid pot. Operation method, put the orchid pot upside down, the orchid seedlings with rotten sprouts facing upward, slowly pull out the planting material around the rotten sprouts, to see the roots of the rotten sprouts, use sterilized scissors, cut off the roots of the rotten sprouts, cut off the roots of the rotten sprouts, and wipe the wound (cutting surface) of the orchid mother plant with carbendazim solution.
Then put the poured raw planting material back into the orchid pot, and water the orchid thoroughly the next day.
2. Orchid rotten sprouts, it is also possible that there is a problem with the orchid root system, causing the orchid to rotten sprouts, if there is? Turn the pot thoroughly, prune the root system of the orchid, cut off the root system of the rotten new sprouts together, disinfect and cool the roots after pruning, and plant it back from the new trace pants. When operating the half-poured pot, you can check the root system in the orchid pot by the way, and turn the pot in time if you find the relationship.
3. If the new orchid seedlings rot, will it affect the other orchid plants in the whole pot? It will definitely affect the other orchids in the pot. Because the new shoots are rotten, there will be rotten liquid bacteria from the rotten buds, which will infect the root system of the original orchid mother plant, which will lead to cross-infection with each other, and seriously affect the orchids in other orchid pots.
All: When encountering such problems, they should not be underestimated and should be dealt with immediately.
Orchid stem rot ** method:
First of all, the whole pot of orchids should be removed, washed, and then all the diseased plants should be cut off, and the decayed parts should be repaired with a razor blade. Then soak the orchid in a sterilization agent for one hour and then leave it in a cool place to dry. >>>More
