Orchids are not growing well, how do you know if they have rotten roots?

According to the subject's description of the title, it is also a normal phenomenon, because the newly planted plants will have a process of slow seedling period, but if the yellowing leaves continue to increase after 2 weeks, it is likely to be caused by excessive watering and unbreathable potting soil, please dry the roots immediately; There is a phenomenon that the leaves are yellow and wilted within a few days of potting, and the root system of the orchid that has just been transplanted into the pot cannot absorb nutrients to the reed head in a short period of time, and the orchid is supplied by relying on the original nutrients stored in the reed.

<> orchid does not have obvious reed head, the energy required by the orchid plant depends on the root system, the orchid root does not work normally in the slow seedling and potting period, and the orchid seedling is consuming the energy reserve of the old seedling, so it is common that the new pot of the orchid will be weeded (also yellow leaves). If it is an old seedling, it is fine, it is a normal physiological phenomenon, caused by plant metabolism, if it is a new seedling, and it wilts in a short period of time, it is bacterial soft rot, only soft rot can make the orchid die within 1 week.

It is not until the orchid root system slowly recovers its ability to absorb water, fertilizer and fertilizer that wilting disappears, and when the absorption of nutrients returns to normal, the leaves turn yellow to green. Only then can it be regarded as a righteous living tree. The maintenance of orchids is mainly the maintenance of the roots, when the pot is just opened, there will be a situation of not accepting the pot, the orchid will appear yellowing and wilting of the leaves, we can wait for it to serve the pot after it.

The temperature is too high or too low, the orchid enters a dormant state, can not take the pot and root normally, the root system can not absorb water and nutrients, the upper leaves slowly yellow wilt, and finally wilt and die Normally, the temperature is too high to transplant, especially when the temperature difference between day and night is too large, it can not be transplanted, orchids are not suitable for high temperature and strong sunshine, so transplanting must be selected at the average daily temperature of about 20 degrees, when the light is not so strong. The orchids dug up will wrap the roots with a little moss, and they will also pass.

Three or four hours, after returning home, you can plant in a pot. It is normal for the orchid leaves to wilt a little, and it can be restored the next day after planting and watering enough root water, and it can be transferred to normal management after being placed in a cool and ventilated place for a week.

First of all, it is necessary to see whether the leaves of the orchid are drooping, and whether the flowers of the orchid are also very weak, if the time is particularly long, it may be rotten roots, which may have something to do with your usual watering too much.

First you should pluck an orchid out and look carefully at the roots of the orchid. Or if the orchid is not growing and the leaves are getting more and more yellow, then the roots are rotten.

You can gently pull your head out and look at the roots of the orchid to confirm whether it is rotten.

The growth rate of crops should be carefully observed, if the roots are rotten, the growth rate is very slow.

In fact, orchids like a moist environment, but the fleshy roots of orchids are afraid of waterlogging, so it is easy to rot roots if they are too wet or rainy, leading to many diseases. So how can you prevent orchid root rot?

Orchids (details).

In winter, orchids are in the dormant or slow growth stage, and the potting soil should be dry; Spring and early summer are important periods for the growth of orchid peanut roots, and the potting soil should be moist. However, long-term overhumidity is also easy to cause root rot, causing leaves to wither and even die. Because of excessive water, the soil is waterlogged and the air permeability is poor, resulting in insufficient oxygen, hindering the respiration of the roots, and causing the roots to turn black and rot. During the rainy season or rainstorm, the orchid must avoid its harm, because of the long rain and humidity, black spots are most likely to occur on the new leaves, and the stamens often have "rotten clothes", which affects flowering and ornamentation.

However, if the potting soil is too dry, it is easy to dry up the pseudobulb or other tissues to lose water and affect the metabolism, which will also lead to weak tissues and poor plant growth. In autumn, the potting soil should be wet, so as to facilitate the removal of leaves and flowers in the coming year. Therefore, orchid growers should know the trick of "not getting wet in winter and not dry in autumn".

The above illustrates the different water requirements of orchids at different times, so the amount of watering should be strictly controlled according to the requirements. At the same time, improper fertilization of orchids is also easy to cause root rot, such as too much fertilizer, too concentrated or liquid fertilizer into the leaf sheath, will have an adverse effect on orchid flowers. When fertilizing, the amount of fertilizer should also be increased or decreased according to the amount of watering, so that it can grow in harmony.

Orchid rotten roots. The main reasons for this are nothing more than improper watering, excessive rainwater, or unreasonable structure of the potting soil, poor drainage, and sometimes the invasion of germs can also lead to root rot.

The first is to change the pot as soon as possible. It is found that the orchid rotten roots, it is necessary to change the soil on the pot planting material, the planting material should pay attention to the quality and water absorption performance, to fire soil or dry soil, charcoal and other planting materials as well, but also in the root reed part of the appropriate cover of some coarse sand, the effect is better.

The second is to control sunshine. For a period of time after changing the pot, it should not be exposed to the scorching sun, and it should be placed in a place with shade and air circulation, but it should be noted that the wind should not be too strong to avoid being affected.

The third is to pay attention to the method of changing potted plants. In addition to ensuring that the potting soil is waterlogged, the planting material from the lower part of the reed head to the outside of the root should be dense, and the reed head should be planted appropriately deeper, which not only plays a protective role, but also prevents the reed head from shaking or floating off the soil surface. Rotten roots and shrunken and yellowing leaves should be cut off to reduce nutrient loss and store nutrients in the reed head to maintain root development.

Fourth, reasonable watering. In the cultivation management, the water should be strictly regulated, and the potting soil should be semi-wet and dry, neither white and dry in the potting soil, but also not obviously too wet. In case of rain, you should move to a sheltered place and try to control the moisture of the potting soil to ensure its normal rooting.

If it is handled in a timely and proper manner, it will still be sent.

Agree with the above guy's point of view, orchid rotten roots are generally caused by overwatering or polluting water.

It may be that the soil is not suitable, and the water retention is too strong.

First, cut off all the rotten roots, the orchid will only have leaves and reeds, how to deal with it will become a version of how to promote the root of the reed head as soon as possible, has reached the supply and demand of nutrients. The method is similar to most of the online, cut off the rotten roots, disinfect, and dry.

2. Prepare clean soft river sand. If there is a pile of sand, take the damp river sand at the bottom, and if there is only dry river sand, soak the river sand in water to make it wet.

3. For the flower pots used in orchids, put some leaves or moss at the bottom to prevent sand loss and also play a moisturizing role.

Fourth, plant the orchid in a pot filled with river sand, and attach some moss to the surface, which also plays a moisturizing role.

Fifth, do not need to water, put the orchid in a cool place, wait for the good news, when the orchid sprouts, the orchid will be reborn.

Orchid rotten roots are the most likely to occur in orchid cultivation since the bai orchid.

The roots are rotten and they are not rescued in time

Governance, orchids can only go to death, whether it is a novice in raising orchids, or a veteran of raising orchids will have rotten roots, veterans are experienced, and the probability of rotten is small, that is, whether the orchid is rotten roots or related to orchid raising technology.

In winter, the roots of the orchid are rotten, how can they be dried, and they will freeze to death as soon as they are dried outside.

It seems that the fake bulb is not broken, and it has its own possibility of survival.

Prune the root system first, cut off the rotten roots, hollow roots, etc., rinse them with clean water, soak the whole plant with carbendazim and other fungicidal drugs for 30 60 minutes, take it out and put it in a cool and ventilated place to hang upside down to dry the surface moisture, if possible, soak it in rooting agent solution for 1 2 hours, then take it out to dry, and dry it until the white roots are chalky and soft, and choose the appropriate pots and planting materials that have undergone strict sterilization and disinfection and transplant them in pots.

After the above treatment, under the condition of proper maintenance, the orchid plant can regenerate new roots and sprouts.

When orchids encounter root rot, treat them first and then prevent them to minimize the chance of root rot.

The cause of root rot in orchids: water is the source of all living things, and orchids must have water to absorb and transport nutrients and metabolize normally. Orchids are fundamental plants.

A small part of the moisture** required for growth is supplied by moisture in the air, and most of the water must be absorbed from the moisture contained in the cultivation medium, which also needs to absorb oxygen from the pores of the substrate. If the substrate in the orchid pot is poorly drained and the moisture content is too high, the water will fill the substrate pores, resulting in water accumulation, the substrate pores are filled with water, the root system is hypoxic, the root system is lost, and the root system will gradually lose its function after a long time. Causes of root rot in orchids:

The water is not clean or the pH value of the water is not suitable. Prepare the appropriate orchid substrate. The seed orchid substrate needs to be filtered and breathable, moist but not 2, dry but not dry.

There are many special materials for orchid planting on the market, and they are also very applicable. For example, the soil of Mount Emei in Sichuan, the bentonite soil in Chongzhou, and the special soil for a variety of orchids in Guangdong are all good materials for orchid cultivation. Some humus can be added to these materials to supplement the lack of fertility.

There are many orchid books that introduce that streams and rivers are most suitable for orchid growth, but most orchid friends live in cities and are not professionally managed in orchid gardens, so it is difficult to meet this requirement. Judging from years of practice, the effect is also very good. If you use tap water or potted pesticides, pay attention to the volatilization of chlorine in the water.

If you water orchids with spring water or pond fish, you should pay attention to test the base pH value with a base number test strip. In the project, what kind of texture of orchid pot is used at the bottom of the orchid pot, the bottom of the pot must have appropriate small holes, and it is better to have a few small holes under the wall of the pot. In short, it is necessary to ventilate and filter the water.

When planting orchids, the lower part of the orchid pot can be covered with broken bricks or charcoal grains to facilitate drainage and ventilation. To decorate orchids, you need to have a suitable temperature, humidity, light and other environments. But to create a good environment for orchids, it is necessary to create a good environment for orchids.

Cultivating good orchids can also grow ideal orchids.

Orchid rotten root solution:First of all, we should take the orchid out of the pot to deal with the rotten roots, but don't use scissors to click too quickly, the root system of the orchid is very developed and entangled, to prune the root system must be straightened by hand, and then pruned, so as not to hurt the roots. After pruning, it is necessary to disinfect and sterilize to kill the bacteria, and finally dry the roots and repot.

The most fundamental reason for the rotten roots of orchids:1.Severe water accumulationXiaoju's suggestion to everyone is that when watering, you should first judge the dryness and humidity of the soil, that is, how dry the water is, you can use a soil moisture detector to measure the moisture, generally only need to insert it into the soil, you can quickly measure the moisture content, and then water according to the remaining amount of water shown by the data.

If you don't want to spend money, you can use a small wooden stick carefully inserted into the soil, and take it out after 30 minutes, if the humidity is very low, it means that the moisture is relatively small.

2.Stuffy roots are impermeable3.Burn the rootsAbout the skills of orchid farming Xiaoju will share with you this, if there are any questions, you can communicate more, let's make progress together!

Orchid rotten roots, what can be done?

If the potted orchid has rotten roots, then the orchid should be depotted, pruned off the rotten roots, sterilized, dried, and put back into the pot, probably because there is too much stagnant water, and the roots are particularly stuffy.

The most common reason is that it is due to overwatering or insect bites, and the orchid can be exposed to the sun in the right amount of sunlight.

Too much fertilizer is applied and not completely absorbed, resulting in root rot, in this case it is necessary to loosen the soil more, and the light is insufficient, this situation is taken out in the morning and evening to bask in the sun, be careful not to take it out at noon.

The reason for the rotten roots of the orchid may be caused by poor ventilation at the bottom of the pot, and then it is who watered a little too much.

Hello, the reason for the rotten roots of potted orchids may be a problem with the soil, and it is recommended to use carbendazim to water the roots.

I feel that there is a pattern to any flower I raise. If you water too much, your roots will rot.

Orchid rotten roots, rule out overwatering, and these 2 reasons.

In the past, watering was a little bit of roots, and the humidity was easy to rot the roots, so it was better to control the watering, and it didn't matter if the soil was dry, and the fleshy roots were afraid of waterlogging.
