The bowl lotus has a little rotten leaves and yellows, I don t know why?

Your description of the situation is incomplete, so you can only guess the reason. I think the biggest possibility is that there is not enough light. The bowl lotus is a miniature lotus flower, and the lotus is a strong positive plant that needs more than 8 hours of sunlight a day to bloom and at least 4 hours of sunlight to barely grow.

Because the lotus grows rapidly, has a strong respiration effect, and consumes photosynthetic products quickly, it is a very shade-tolerant plant. Long-term lack of light will lead to the consumption of photosynthetic products by respiration is greater than the photosynthetic products accumulated by photosynthesis, and the growth of lotus flowers will be stagnant, the resistance will decrease, and in severe cases, it will "starve to death". Can your bowl lotus be dried for more than 4 hours on a sunny day?

There is also a possible cause, which is caused by your managing. Bowl lotus usually does not need to be fertilized, fertilization is easy to cause fertilizer damage, the smaller the pot, the more obvious the fertilizer damage, the usual manifestation is that the young leaves are shrunken, the petiole elongation speed is slowed down, and the leaves even crack. But looking at what you described, it doesn't quite look like this situation.

Under normal circumstances, the bowl lotus will not have leaf rot, and the bowl lotus is honest, it is still very good to plant, and the growth is very rapid. Therefore, if there is an abnormal phenomenon, it is likely to be caused by the poor cultivation environment. Insufficient light and not planted in the soil belong to a harsh cultivation environment.

1. Lack of fertilizer: Bowl lotus likes fertilizer during the growth period, especially potassium fertilizer. If there is a long-term lack of fertilizer, the leaves of the bowl lotus will turn yellow, the leaves will rust spots, and the leaves will gradually wither and die from the periphery to the center.

2. Insufficient light: bowl lotus likes strong light, about eight hours a day, if the light is insufficient, it will lead to the inability to carry out normal photosynthesis, which will affect the growth of leaves, and the leaves will be yellowing and long, so the leaves should be often exposed to the sun.

3. The temperature is too low: the temperature of the bowl lotus period is generally kept at about 30 degrees, if the temperature is lower than 15 degrees, it is easy to cause the leaves to wither and turn yellow.

4. Water quality: There is chlorine in tap water, and it is easy to cause dead leaves if used directly, so tap water should be exposed to the sun for one or two days before use.

5. Stem and leaf decay: In the process of breeding, some stems and leaves will die and rot, which will affect the normal growth of bowl lotus. Rotten stems and leaves can be removed, rinsed, and replaced with water.

6. Soil fertilizer and seedlings: Bowl lotus likes light fertilizer, so don't add too much fertilizer at ordinary times, it is easy to burn roots and rot. Generally, when 4 to 5 pieces grow, you can apply fertilizer for the first time, do not pour it directly in the pot, and wrap the fertilizer in mud.

7. Soil: Generally, yellow mud and sandy vegetable garden soil can be mixed. When the bowl lotus grows one or two leaves and has a white root system, it can be transplanted into the soil.

Bowl lotus is not so easy to feed! Here we will teach you how to fertilize the bowl lotus to keep the leaves away from yellowing and other problems.

Fertilization tips:

1. Potassium fertilizer should not be poured directly into the pot, but wrapped in mud to make a ball, which is slightly dried and stuffed into the mud in the middle of the pot.

2. The first fertilization is generally carried out in the pot lotus growing 4 to 5 floating leaves, which is equivalent to "colostrum fertilizer", the quality and quantity should be reasonable, with imported diammonium phosphate as the top, followed by the most reliable nitrogen, phosphorus and potassium ternary compound fertilizer. Apply 10 to 16 grains per pot per application.

Tips for using soil:

1. Generally, it is advisable to mix yellow mud and sandy soil in a ratio of 7:3, and you can also directly choose the garden soil of vegetable land.

2. When to put the soil, when the first leaf is released, the second leaf is about to be released, and when the white root system grows 1 2 cm, it can be planted in the soil.

Bowl lotus fertilization needs to be carried out step by step, not quickly. Applying too much fertilizer, especially nitrogen, can cause the leaves to turn yellow if too much. When too much fertilizer is applied, a large amount of overflow treatment is done to dilute the fertilizer.

Lack of fertilizer will also lead to yellow leaves, if there is a lack of fertilizer, it is necessary to apply fertilizer in time and reasonably, and a small amount of bean curd bran can be added to the potting soil as a base fertilizer before planting.

Lack of light may cause the leaves to turn yellow. Since the leaves are unable to photosynthesize properly, chlorophyll synthesis is affected, resulting in yellowing of the leaves. Therefore, it is necessary to ensure that it has sufficient sunlight time, place it in a position where it can reach sunlight, and change its position in time according to the changes of the sun.

Ensure sufficient sunlight and avoid scorching sun exposure, and block strong sunlight at noon.

In winter, when the temperature drops sharply or the temperature difference is too large, it may cause the leaves of the bowl lotus to turn yellow. When its leaves turn yellow because of the low temperature, it is necessary to take thermal insulation measures in time, and the container of planting plants must be filled with water, and it is best to cover the container mouth with a layer of plastic paper to avoid frostbite of the plant, and open the plastic paper for ventilation at the appropriate time. If necessary, move it indoors at a suitable temperature.

1. Common causes of yellowing of bowl lotus leaves:

1. Water quality problems: There are many reasons for the yellowing of bowl lotus leaves, including water quality problems. If there is too much chlorine in the tap water used, yellow leaves will appear.

2. If the temperature is too high or too low: it may also be related to temperature, when the growth temperature is too high or too low, the leaves will cause burns or frostbite.

3. Excessive fertilization: In addition, it is also possible that the bowl lotus is overfertilized during the maintenance period, and the concentration of the roots is too high to cause root burning, which causes its leaves to turn yellow.

Second, the bowl lotus yellow leaf remediation square pants mu method:

1. Change the water: If the phenomenon of the yellow leaves of the bowl lotus is more serious, you can change the water first, and put the tap water in the sun for exposure, so that the chlorine can be volatilized.

2. Warm measures: When the temperature is high, we should pay attention to the work of shading, and when the temperature is too low, we should take thermal insulation measures in time, and it is best to cover the container mouth with a layer of plastic paper to avoid frostbite.

3. Proper fertilization: Bowl lotus can be properly fertilized, if you accidentally fertilize too much, dilute the residual fertilizer in the soil with water and discharge it.

4. Daily maintenance: bowl lotus likes to grow in a sunny environment, only the potting soil becomes warm, it will make it develop more Hu Kuansen faster, and receive at least 6 hours of light during the growth period. When watering, it is necessary to pay attention to let the leaves float on the surface of the water, and to change the water source frequently, it must be clear water.

Summary. You pick up the soil to see if the soil is black and smelly, if it is, it is too much organic matter in the soil, fermentation and burning roots, and change the soil as soon as possible.

Switch to plain soil, it is best to soak in boiling water for a while, add some carbendazim to the soil to try, and the water should not be too alkaline.

It is best to peel off the shell of the lotus seed before planting.

Top dressing after leaf erection should first ensure survival.

You pick up the soil to see if the soil is black and smelly, if it is, it is too much organic matter in the soil, fermentation and burning roots, and change the soil as soon as possible. Switch to plain soil, it is best to soak in boiling water for a while, add some carbendazim to the soil to try, the water can not be too alkaline before planting it is best to remove the shell of the lotus seed and then top dressing the leaves, first of all, to ensure survival.

The leaves of the bowl lotus are black and rotten, which may be due to too many bacteria in the soil or water, which leads to the invasion of germs into the bowl lotus, affecting the normal growth, and causing the leaves to turn black and rot. In addition, if the leaves of the bowl lotus are black and rotten, you need to cut off these leaves first. Because the concentration of fertilizer in the water body is too high, it will cause this phenomenon.

Therefore, it should be replaced with new water to dilute the fertilizer concentration in the water body. At the same time, it is necessary to supplement the light for the bowl lily. If the disease causes the leaves of the bowl lotus to turn black and rot, it should be sprayed with fungicides to prevent and control.

Bowl of envy repentance lotus leaf hair brother black rot solution:

1. Pruning: The leaves of the bowl lotus are black and rotten, first of all, it needs to be properly pruned to cut off all its black and rotten leaves. This is done to prevent these leaves from polluting the water and preventing it from harming other normal leaves.

The rhizomes of the bowl lotus, which were severely damaged during pruning, should also be removed.

2. Replace the new water: When cultivating bowl lotus, if too much fertilizer is applied, resulting in too high fertilizer concentration in the key body before water, then the leaves of bowl lotus will be black and rotten. Therefore, at this time, it is necessary to replace the bowl with new water, and it is best to pour out half of the water in the pot.

Half of the new water is then added to dilute the fertilizer concentration in the water.

3. Supplemental light: Bowl lotus is a light-loving aquatic plant, and when the light is insufficient for a long time, it will not be able to photosynthesize well. In this way, its leaves will also turn black and rot, and this phenomenon will occur.

In this case, we need to add light to the bowl lotus, and it is best to move it to a sunny place to maintain it, so that it can grow and bloom vigorously.

4. Prevention and control of diseases: If the water quality is not clean, the bowl lotus will produce diseases, which will also cause its leaves to turn black and rot. In this case, it is necessary to replace the bowl lotus with clean and clean water.

At the same time, it is also necessary to spray the bowl lotus with a special fungicide during maintenance. In this way, the germs can be completely eliminated, so that the bowl lotus can be restored to health.

Too much fertilization Too much fertilization causes the soil and water to be too fertile and relatively dry, the water absorption capacity of the leaves is weakened, and the water required for their own growth cannot be reached. Excessive fertilizer will affect the absorption of water from the leaves of the bowl lotus, resulting in seedling burning and leaf blackening.

Bacterial infection When planting, the soil is not sterilized, or the water is not clean, bacteria will breed, affecting the growth of bowl lily, resulting in black leaves.

Insufficient light In the case of insufficient indoor light, it will put the bowl lotus in an excessively humid environment, and due to insufficient light, it will affect the photosynthesis of the plant, and the leaves cannot grow normally.

Water quality and quantity Bowl lotus is suitable for growing in acidic soil, if the water quality is alkaline or dirty during the watering process, changing the soil quality will cause the leaves to turn black.

Another reason is the lack of water, there is less water in the pot, and if it is not watered in time, it will also make the leaves of the bowl lotus black.

If there is too much fertilization, the water should be changed immediately, be careful not to change all at once, change half each time, and reduce the concentration of fertilizer in the water. When changing the water, the temperature difference of the water temperature should not be too large, so as not to change the pH and affect the water absorption of the leaves. In addition, if you apply too much fertilizer, you can also turn over the pot and change the soil.

If the leaves are blackened due to dirty water quality, it is recommended to turn the pot directly and change the soil, not directly change the water, otherwise the water temperature changes, acid and alkali changes, and the condition will be aggravated. The correct way to do this is to wait for the water to evaporate and then add isothermal water.

Note that there must be no lack of water during the growing season of bowl lotus, otherwise the leaves are easy to scorch.

Outdoor maintenance Except in winter, try to keep it outside the house during the day, and get more sunlight, but avoid direct sunlight.

Pruning and cleaning bowl lotus leaves are very susceptible to disease during the growth period, so the bad leaves should be cut off in time, and carbendazim should be used for disinfection and sterilization, and an appropriate amount of diluted pesticides can also be sprayed.

Rotting and burning of lotus seeds will also make the leaves black, so you can pull out those lotus seeds that rot and show symptoms.

There are four reasons why all the leaves of my bowl lotus are black and rotten:

1. Water quality. Bowl lily is suitable for growing in acidic soil, and if the soil quality changes or the water is dirty, the leaves will turn black.

2. Water volume. Afraid of flooding, water depth is easy to rot leaves, the water should be shallow in the early stage, and gradually deepen in the later stage, if not watered in time, the leaves will also be blackened.

3. Bacterial infection.

When planting, the soil is not sterilized, and the water pollution will breed bacteria, affecting the growth of bowl lily, resulting in black leaves.

4. Illumination. If the light is insufficient, it will affect the photosynthesis of the bowl lotus, and the leaves can not grow normally.

The transmission route of bowl lotus rot disease: the mycelium is overwintered in the seed lotus root and the spores are overwintered in the soil, and the fungus-carrying seed root and the diseased soil become the main source of infection.

Pathogenesis conditions of bowl lotus rot disease:

1. Continuous rain, insufficient sunshine or frequent storms are easy to induce this disease;

2. Poor soil permeability or high acidity in lotus root field, sewage entering the field or water temperature higher than 35 are easy to induce this disease.

Rotten leaves are due to bacteria in the water or the soil is not soaked well and planted on the zhi dao cause root rot If there are new leaves growing back out, then it is the cause of the bacteria You can add 2g of methyl or carbendazim to the water, which is conducive to killing the germs If there is no new leaf growth, then it may be a problem with the soil Generally, the seeds below will rot There is no way to treat it. There is also the one that has not been planted and needs to be planted, and it will eventually die if it is raised in water Because there is no soil to supply growth and nutrients, so the leaves will be thinner The probability of susceptibility will increase, and the soil must not be scalded with boiling water twice before planting.

The water is relatively clear, so it should be changed frequently, right? It is recommended to remove the rotten leaves, and then add carbendazim to the pot for disinfection, and increase the light, and ensure that the bowl lotus is exposed to direct sunlight for more than 6 hours a day, so that it can grow well and is conducive to flowering.
