    There are many reasons why the leaves of water lilies turn black: if it is caused by a large amount of fertilizer, it is necessary to increase the amount of water to dilute the fertilizer, or change the soil. If it is caused by a bacterial infection, the blackened leaves should be cut off and sprayed with carbendazim.

    If it is caused by insufficient light, it is necessary to increase the sun exposure appropriately. If the water quality is not clean, clean water should be used for aquaculture, and the water temperature difference should not be too large.

    First, the reason for blackening.

    There are actually many reasons for the blackening of water lily leaves, if too much fertilization is applied during the growth period, this phenomenon will occur, too much fertilization will reduce the water lily leaves, and the ability to absorb water will decrease, resulting in the phenomenon of black and zooming of the leaves.

    Secondly, the cause of the black leaves of the water lily is the infection of the bacteria, if the water lily is infected with the bacteria, there will be various problems, including the leaves blackening.

    In addition, when the light is insufficient and too humid, the leaves of the water lily are also easy to turn black, because the growth environment of the water lily is too humid at this time, it will turn black, and it will rot seriously.

    Another reason is that the water quality is not clean, and when the water is dirty, the leaves of the water lily are prone to turn black.

    2. What to do if it turns black.

    If there is too much water and fertilizer when breeding water lilies, you can change the water immediately, and pay attention when changing the water, you should first replace half of it to keep the water temperature close. If too much base fertilizer is applied at the time of planting, it is necessary to turn over the pot and change the soil again. Fertilization can be done by spraying potassium dihydrogen phosphate in fertile leaves.

    During the growth of water lilies, if they are infected with germs and leaf disease occurs, it is necessary to cut off the blackened leaves and spray them with carbendazim solution.

    In addition, it is also necessary to strengthen the sunshine, if the water of the water lily is dirty, it is necessary to replace it with clean water, and pay attention to the water temperature when changing the water, so as not to change the pH of the water.

    If the lotus leaves turn black and you have two small fish in your pot, there may be a few reasons and solutions:

    1.Water quality issues: The water quality in the fish tank may contain too much waste and ammonia, causing the lotus leaves to turn black.

    Check the water quality of the fish tank, and if there is an abnormality, consider replacing a portion of the water or doing proper filtration and cleaning to keep the water clean. Also, make sure that the water level in the fish tank is appropriate to avoid over-soaking the roots of the lotus.

    2.Hypoxia Problem: Fish in a fish tank may consume oxygen in the water, resulting in a lack of oxygen in the lotus roots. This may cause the lotus leaves to turn black. Provide adequate aeration and water circulation to ensure adequate oxygen to the roots of L. Pure Ho.

    3.Nutritional deficiencies: Fish in the tank may compete for the nutrients needed by the lotus flowers, causing the lotus leaves to turn black. Consider supplementing the lotus with appropriate plant fertilizer to meet its growth needs.

    4.Disease contagion: If pathogens are present in the fish tank water, it may cause the lotus leaves to develop disease and turn black. For infected leaves, you can cut them off and dispose of them promptly to prevent the disease from spreading further.

    In summary, it is necessary to pay attention to the aspects of fish tank water quality, oxygen**, nutrient supplementation and disease prevention. If the problem persists, it is advisable to consult a professional gardener or pet specialist for professional guidance and assistance.

    The blackening of lotus leaves can be caused by a variety of reasons, including oversprayed pesticides or fertilizers, diseases and insect pests, water quality problems, excessive sun exposure, etc. These problems need to be dealt with correctly in order to restore the health of the plant. Here are some coping strategies:

    Determine the cause of the problem: First, we need to determine the cause of the problem. If it is caused by oversprayed pesticides or fertilizers, we should stop using it immediately and rinse the plant with clean water.

    If it is caused by diseases and pests, we need to use appropriate pesticides or disease control agents.

    Disease control: If it is caused by a disease or pest, appropriate pesticides or biological control methods can be tried. Common lotus diseases include leaf spot, anthracnose, etc., which need to be carried out with corresponding pesticides.

    Control environmental conditions: Lotus flowers need proper sunlight, but too much sunlight can darken the leaves, so consider moving the lotus to semi-shade. If the leaves are blackened due to water quality problems, it is necessary to replace the clean water and pay attention to the pH value of the water quality.

    Correct fertilization: The demand for fertilizer for lotus flowers is not high, and too much fertilization can easily lead to black and lead deficiency in leaves. If it is caused by excessive fertilization, it is recommended to reduce the use of fertilizer and use organic fertilizer if possible.

    Pruning diseased leaves: If some leaves have turned heavily black, they can be pruned to avoid the spread of the disease and can help the plant recover by reducing its burden.

    Provide adequate air circulation: This helps prevent the growth of bacteria and fungi, which are often the cause of the leaves turning black.

    In any case, if the problem persists, or if there are serious problems with the overall health of the lotus, it may be necessary to seek the help of a professional horticulturist or plant pathologist.

    Not ventilated. If the indoor air is not circulated, the oxygen content of the water in the hydroponic plant will drop sharply, causing the plant to turn yellow and lose its leaves due to lack of oxygen.

    The temperature is too low. When the ambient temperature is lower than the safe overwintering temperature, due to the weakening of the physiological activity of the plant and the reduction of absorption capacity, the plant will shed a part of the leaves to adapt to the low temperature environment in order to reduce the consumption of water. In severe cases, the blades will completely fall off, leaving only the bare rods.

    The concentration of the nutrient solution is too high. Concentrations that are too high can cause fertilizer poisoning, which can cause defoliation.

    The water was not changed in time. When the water change interval is too long, the oxygen in the water cannot meet the needs of flower growth, and the number of microorganisms increases, which often causes root rot of hydroponic flowers. Since the absorption of water and nutrients is greatly reduced after the flower rots, it will cause a large number of defoliation.

    1. Bowl lotus is suitable for growing in acidic soil, if the water quality of the bowl lotus is alkaline or dirty, changing the soil quality will cause the leaves to turn black; Then there 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 and withered.

    2. Too much fertilization, resulting in too fertile and relatively dry soil and water, weakened water absorption capacity of leaves, 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. Generally, Bika water-soluble fertilizer is selected, and it is fertilized after secondary dilution.

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

    There are the following reasons for the yellowing of lobelia leaves, which can be treated.

    1. Dry yellow. The yellow of lack of water is different from the yellow of water, the yellow of lack of water is the withering and dry leaf tips or edges, and the old leaves are withered and yellow from the bottom to the top, but the growth of new leaves is relatively normal. Pay attention to watering when watering enough, water thoroughly.

    Second, lack of fat yellow.

    It is manifested in the color of young leaves becoming lighter, yellow or light green, while old leaves are more normal or gradually turning from green to yellow. It is necessary to check the potting soil frequently, if there is a dry knot phenomenon, the soil should be replaced, and the thin fertilizer should be applied diligently, and some alum water should be poured in a timely manner to replenish iron.

    Third, the lack of light yellow.

    If the leaves are shaded for a long time, the leaves will not get enough sunlight to form chlorophyll, and the whole leaves will turn yellow and then fall off, and this disease can be avoided by supplementing light.

    Fourth, fat yellow. The yellowing of flowers caused by excessive fertilization or excessive concentration is manifested in dry brown at the top of the new leaves, and the general leaf surface is thick and dull, and the concave and convex are not stretched, and the old leaves are scorched and yellow. Fertilization should be stopped immediately, and part of the fertilizer should be washed with plenty of washing in severe cases.

    Fifth, burn yellow. Strong sunlight directly onto some shade-loving flowers (such as spider plants, hostas, etc.) is easy to cause the leaf tips and leaf margins of flowers to wither, and the sunny part of the leaves to appear yellow spots. Move to the pubic area.

    Sixth, water yellow. The young leaves are dark yellow and dull, the old leaves have no obvious changes, the branches are small yellow-green, and the new shoots are shrunk and not long, indicating excessive watering. Depot the flowers, put them in a ventilated and cool shade, and dry the soil ball before putting them back into the pot.
