3. The soil of the repotted Junzi orchid is best in a moist state, so that there is no need to water it after potting, so as not to make the potting soil too wet and not conducive to the wound. After potting, place it in a cool and ventilated place, wait for the orchid to take root, it generally takes 1 or 2 months to give birth to new roots, during this period, do not be in a hurry to shake the orchid, so as not to damage the new roots that have just grown.

Rhizome rot disease.

1) Symptom characteristics.

Both false bulbs and leaves can be damaged. The stem is infected, the initial dark brown water-stained spots, irregular shape, the stem tissue quickly becomes soft and rotten, causing the whole plant to collapse. Leaf infection mostly begins at the base of the leaf, the leaf loses its luster, and dark green water-stained spots are produced on both sides of the leaf, which then expands upwards and downwards along the veins, and the diseased part becomes soft and rotten, and the leaves droop or fall off.

The stems and leaves of the infected stem and leaves emit a foul odor. Pathogenic bacteria often invade from wounds. In summer, it is easy to develop diseases when the temperature is high, the humidity is high, and the ventilation is poor.

2) Prevention and control methods.

The cultivation of Junzi Orchid should use humus soil or special soil for Junzi Orchid with loose texture, good water retention and ventilation, and it is best to use it after high temperature disinfection.

Watering along the edge of the pot, avoiding top watering, pouring water into the heart leaves, and keeping the room ventilated and fresh.

Avoid all kinds of insect wounds and man-made wounds.

At the beginning of the disease, spray or water 3000 times of medical streptomycin sulfate or 800 times of 47% Garinone wettable powder, 600 times of 12% green milk copper emulsifiable concentrate, and 4000 times of 1 million units of neophytomycin.

Many flower friends of the Gentleman's Orchid have raised the issue of maintenance. The flowers of a pot of orchids that had been cut off by arrows had all drooped, and the soil of the orchid was torn open, and the roots of the orchid were found to be rotten. Let's take a look at the causes and reasons for the root rot of the Junzi Orchid, and even lead to the root empty.

1.Water often. We can look at these empty roots.

These Gaiqing brother roots are already empty, and then this plant material is very wet, and the whole plant material is very wet. Then it's because we usually water too much. If you water it frequently and the environment is not ventilated, it can easily lead to Junzi Orchid root rot.

Then, the gentleman's orchid can see its bottom, but only guess that there is only one left, and the connection of this one is unstable. So if this happens, you can first prune the roots a little and leave some rotten roots, because it is useless to keep them. 2.

The potting soil is too dry. If it's like this root system, it's actually broken. It doesn't matter if we want it or not.

Then, if it's at the bottom, here there are two more root systems on either side. We see that there are two root systems here. So why are these two root systems going up?

In fact, it may be because this potting soil has been in a drought state for a long time before, and then this root system has gone up, and there is more watering in the later stage. Potting soils are always in a particularly sultry state, and if there isn't much oxygen for these roots to grow, they will grow in fresh air. So if we find your junzi orchid, we have to see if it is potting soil, and then the potting soil is too dry or this potting soil.

Like this, the potting soil was too dry before, and then a large number of empty roots appeared, plus too much watering in the back and the roots were suffocated. 3.Sterilized with carbendazim solution.

We can break off two leaves at the base of this root system. These two leaves have withered. Since the roots have been cleaned up, let's disinfect them again.

Carbendazim solution can be used. Carbendazim is diluted with water at a ratio of one to one, and then we put this gentleman's orchid in it and soak it for about half an hour, until there is still an hour left, so that it has a sterilizing effect. However, it should be noted that when soaking, the nuclear attack base and center of the entire leaves of the monarch orchid cannot be soaked in water.

We just need to soak the roots at the bottom.

The flowers are bright and the ornamental value is high, but it is not easy to raise the orchid well, and it is necessary to master good breeding techniques. Without adequate care, the leaves of the orchid can easily turn yellow. In addition, Monarch Orchid may also have rotten roots.

What should I do if the roots of the Gentleman's Orchid rot? When you encounter a problem, analyze the cause first. The following gardener uncle will introduce the causes and solutions of Junzi Orchid root rot.

1. Causes of root rot of Junzi orchid: too high temperature, too much watering, too much base fertilizer, too sticky soil, poor pot ventilation, incomplete application of fermented fertilizer, and poor soil disinfection will cause root rot. When the hot summer comes, if you don't pay attention to water control, it will be easy to root rot, and bacterial infection will also cause root rot.

Second, the solution to the rotten roots of Junzi Orchid 1. Clean up rotten tree roots. Plant the rotten roots of the orchid from the pot, gently peel off the soil, then rinse the roots with water, and cut the rotten roots with scissors.

2.Root disinfection. Soak the cleaned roots in potassium permanganate solution for 5 minutes, then dip a little sulfur powder or plant ash or multi-bacterium chain cavity, and then dry in the shade.

3.After the replanting of the orchid is dried, it can be planted in sandy soil to promote the germination of new roots. If the root system is not rotten, it can be placed directly in a pot instead of planting in sandy soil.

After planting, it is necessary to control the water to avoid root rot again. Put it in a cool and ventilated place in the shade. After 30 days, if the leaves do not wither, it will survive.

Raise flowers, go to the gardener's forum:, sing and laugh all the way. It's so lively on the road to raising flowers!

Many flower friends of the Junzi Orchid raised the question of maintenance, a pot of Junzi Orchid had cut the flower arrows before, all of them had drooped, and opened its soil, and found that the Junzi Orchid had rotten roots, specifically look at why the Junzi Orchid will rot the roots, and what is the reason for the rotten roots, and even cause the situation of empty roots.

1. Frequent watering.

We can look at these roots that have been empty, these roots have all been empty, and then this planting material, especially damp, the whole planting material is very wet, then this is because we usually water the state erection a lot.

If you water frequently, coupled with the lack of ventilation in the environment, it is easy to cause the lack of big rotten roots in the Junzi orchid. Then, this junzi orchid can see its bottom, in fact, there is only one root system left, and its connection with this root system is also unstable. In this case, first of all, we can prune the root system a little and remove some of the remaining rotten roots, because it is useless to keep them.

2. The potting soil is too dry.

Like this root system, it's actually broken, it doesn't matter if we want it or not, and then at the bottom, there are still two roots on both sides of this side, so we see that there are two roots that go up, so why do these two roots go up?

In fact, it may be because of this potting soil, which was in a long-term drought situation before, and then the root system went up, and later watered too much, the potting soil has been in a particularly stuffy place, and there is not a lot of oxygen to grow these roots, so it will grow in a place with fresh air.

So if we find your Junzi orchid, we have to see if it is potting soil, and then the potting soil is too dry or this potting soil, like this, the potting soil is too dry before, and then there are a lot of empty roots, plus the roots are overwatered later.

3. Sterilization treatment of carbendazim solution.

We can break off the two leaves at the bottom of this root system, these two leaves have drooped, because the root system is cleaned, and we can give it a sterilization treatment, we can use carbendazim solution.

Dilute carbendazim and water in a ratio of one to one, and then we put this junzi orchid into it and soak it for about half an hour, to an hour, so as to play a sterilization and disinfection effect.

However, when you pay attention to soaking, you can't let the whole Junzi orchid sit on the base and the center of the leaf is soaked in water, we only need to soak the root part at the bottom.

The root system of the orchid is fleshy, not resistant to waterlogging, if it is watered too frequently or the amount of water is too large, it is easy to root the roots, and it is afraid of thick fertilizer or raw fertilizer, if the fertilizer is not properly applied is also easy to rot the roots, the orchid has high requirements for the soil, if the soil is too sticky, it will hinder the root respiration, and it is easy to rot the roots after a long time, and the roots will also rot if the orchid is infected with diseases.

The root cause of the rot of the gentleman's orchid.

1. Watering too much:The amount of watering for the orchid needs to be appropriate, and the amount of water should be strictly controlled, because its root system is fleshy and not resistant to waterlogging, if it is watered too frequently or the amount of water is too large, it is easy to root and cause the root system to rot.

2. Improper fertilization:Although it is a fertilizer-loving plant, it is afraid of thick fertilizer or raw fertilizer, if the fertilizer concentration is too high or not rotted when topdressing, it is easy to hurt the roots, resulting in root rot.

3. Soil discomfort:Root rot may also be caused by soil discomfort, it has high requirements for soil, if the soil used is too sticky, it will hinder the root respiration, and it is easy to rot the roots after a long time.

4. Infectious diseases:During the maintenance period, if the environment provided by the orchid is not suitable, it is easy to be infected with diseases, affect the growth of the orchid, and even have rotten roots.

Gentleman's orchid rotten root treatment.

1. Watering:Orchid has a certain drought tolerance and does not need to be watered frequently, usually waiting until the soil is dry before watering, control the amount of watering, and strengthen ventilation after each watering to ensure air circulation.

2. Fertilization:Top dressing for Junzi Orchid must be carried out with thin fertilizer diligently, before the fertilizer is used, it should be diluted with water, avoid using raw fertilizer or thick fertilizer, if there is fertilizer damage, immediately pour a large amount of water to dilute.

3. Soil:The soil used in the cultivation of Junzi Orchid must be soft, breathable, permeable and rich in humus, and the soil prepared by yourself must be disinfected before use.

4. Diseases:Once the disease is found, it is necessary to isolate the orchid as soon as possible, prune the diseased part, and spray the agent to treat it, so as to promote it to resume growth as soon as possible, in addition, try to provide a warm and well-ventilated environment during the later maintenance.

Prevent the rot of the roots of the gentleman's orchid.

Junzi Orchid likes cool, well-ventilated, sunny environment, it is best to provide a temperature of 15 to 25 during the maintenance period, although Junzi Orchid likes light, but is afraid of direct light, strong light, to block in time, Junzi Orchid likes to sell fertilizer and, not only in the cultivation to apply the bottom fertilizer, the growing season also needs to top dressing to star, so as to grow healthily.

Three reasons, such as excessive wetness, excessive fertilizer, and insect infestation, will lead to root rot in Junzi Orchid. If you want to solve the problem of sex with spinal fluid, you have to find out the specific cause of rottenness.

The reason why it is often said that the orchid is difficult to raise is that there is no in-depth understanding of the structure of the plant and the growth habits buried in the genes. For friends who have been planting for a few years, they will think that Junzi Orchid is a lazy plant. To get to the point, let's first look for the causes of rotten roots and give practical solutions.

1. Overwatering, causing water accumulation.

Junzilan naturally loves a moist environment, which many friends know; That is why it is necessary to let go of watering too much and strive to ensure that the soil does not have dry periods, which will cause excessive water accumulation to soak and rot the roots. Why do you water the wild and rotten the roots according to your habits? That's because the fleshy roots + false bulbs have a super water storage capacity, and a dry period is needed before watering to avoid stagnant water or excessive water.

2. Improper fertilization burns the roots.

I have personally maintained the Junzi Orchid for so many years, and I feel that it does not need a lot of fertilizer**, and it is a plant with low fertility tolerance. Once you have experienced the beauty of the flowering of the Gentleman's Orchid, you must not help but fall in love with it. If you intensify fertilization in order for the flowers to bloom, it will cause fertilizer damage.

If there is too much fertilizer in the soil, if it is not absorbed in time, it will heat up and burn the roots.

3. Breeding insect pests and corroding roots.

In summer and autumn, when the temperature is relatively high, if you apply a fertilizer with a strong smell, it will attract insect pests such as ants. In the early stage, it has no effect on the roots, but in the later stage, it will slowly corrode and breed bacteria, which will lead to root rot.

Generally speaking, the root rot of Junzi Orchid is inseparable from the above three reasons, and now for the specific reasons, a detailed analysis will be made.

Overwatering, improper fertilization, and insect erosion can cause root rot. Ryoko felt that no matter what the reason, it was necessary to change the pot and change the soil. Depot the plant as a whole, remove the original soil, and prune the rotten and blackened roots.

It is then sterilized with potassium permenite, then dried and replanted.

All in all, for a gentleman who has rotten roots, only by taking the way of repotting and changing the soil can it be possible to save his life. However, the subject must also be targeted** in order to avoid the same problem in the future.
