Does the yellowing of lotus leaves mean that it will not wilt? Why are lotus leaves yellow?

There are three situations in which the lotus root leaves turn yellow and wither, namely, insufficient nutrients, diseases and insects sucking the juice of the lotus root, and the newly grown lotus root leaves have not yet undergone photosynthesis. If the lotus root leaves are yellow because of insufficient nutrients, then an appropriate amount of nitrogen, phosphorus and potassium fertilizers can generally be applied to the lotus roots, and the ratio of nitrogen, phosphorus and potassium fertilizers is generally 2:1

3 is appropriate. >1. What should I do if the lotus root leaves turn yellow and wither?

1. The newly grown lotus root leaf itself is yellow, and the reason why it turns green later is because it turns green after photosynthesis produces chlorophyll. Therefore, if you see that the lotus root leaves are yellow, you can observe them for a few days before making a judgment.

2. The yellowing and withering of lotus root leaves may be due to pests and diseases, such as water maggots, which will suck the juice contained in the rhizomes and leaves of lotus roots, causing lotus leaves to turn yellow. If this is the case, you can use the right amount of lime to drive it away.

3. The yellowing and withering of lotus root leaves is also related to the problem of nutrients, the absorption ratio of pure nutrients of nitrogen, phosphorus and potassium is about 2:1:3, and there is more demand for nitrogen and potassium, and at the same time, it also has an appropriate demand for calcium, boron, zinc and other micro-fertilizer elements.

If it is judged that the yellowing of lotus root leaves is due to insufficient nutrition, it is necessary to spray the foliage, such as trim amino acid foliar fertilizer, which can fully supplement the nutrients of lotus root.

What causes lotus leaf wilting.

There are many causes of lotus leaf wilting, which are related to water, light, fertilizer, and disease. During the maintenance period, water and fertilizer are insufficient, lotus leaves lack water and nutrients, leaf growth is poor, and there will be dryness. During the maintenance period, the light is insufficient, the lotus leaf can not carry out photosynthesis, the leaves will turn yellow and dry, and the leaves will curl or wither after being attacked by pathogens.

Lotus leaves are aquatic plants that prefer warm, moist, and well-ventilated environments. During the maintenance period, if the water is insufficient, the lotus leaves will gradually wither in a state of lack of water. In the hot and dry climate of summer, if the lotus leaves are not replenished with water in time, the leaf spray will wilt.

Lotus leaves love light and are suitable for growing in a sunny environment. During the maintenance period, the lotus leaves are placed in a cool indoor position for a long time, and the lotus leaves lack light, and the leaves will turn yellow and wither. Only in an environment with sufficient light can lotus leaves carry out photosynthesis, accumulate nutrients, form a large amount of chlorophyll, and make the leaves green.

Lotus leaves need to have sufficient fertilizer during the growth period, and sufficient nitrogen fertilizer during the growth period. Nitrogen fertilizer can provide nutrients for lotus leaves, and is also conducive to the formation of chlorophyll, which can make the leaves more vibrant green. During the maintenance period, if fertilizer is not applied to the lotus leaf in time, the lotus leaf lacks nutrients, the leaf growth is poor, and the phenomenon of wilting and yellowing will occur.

During the growth period of lotus leaves, after being attacked by pathogens, the leaves will also appear dry, yellow and wilted. Common diseases of lotus leaves are wilt and spoilage. In the early stage of the disease, the color of the lotus leaf will become lighter, the edge will begin to turn yellow, and the later leaf will gradually yellow, curl, dry and wither, which can seriously cause the lotus flower to die.

The yellowing of lotus leaves is caused by a lack of fertilizer.

You can give the canteen an appropriate amount of fertilizer to supplement nutrition. Promote the growth of chlorophyll, I hope it can help you.

It's autumn and the lotus leaves are turning yellow and wilting, especially north of the Yangtze River. The south may be a little later. This is normal. There's nothing you can do about it. Starting next spring, new leaves will grow.

Add some nitrogen fertilizer or spray nitrogen-containing foliar fertilizer.

The yellowing of the leaves of the lotus may be caused by the following points, one may be the lack of light during the growth process, which causes the photosynthesis of the plant to be affected and cannot be carried out normally, the leaves will turn yellow, and the lotus flower needs to be placed in a good light position; It is also possible that improper fertilization occurred during the breeding process; The turbidity of the water quality of the lotus may also cause the leaves to turn yellow, and the water needs to be changed frequently; It is also possible that there is an insect infestation and can be sprayed.

1. Too much fertilization.

Reason: Although a certain amount of nutrients are needed in the growth of lotus, once too much fertilization is usually applied, the lotus cannot be absorbed normally, which will cause the root at the bottom to burn out, the function of absorption and transportation will be affected, and the growth will be problematic, which will lead to the drying up of the leaves of the lotus.

Solution: You can observe the roots, if the roots are black and short, it may be burned, you need to control the fertilization, if necessary, you need to replace the substrate inside.

Second, the temperature is low.

Reason: The lotus flower cannot withstand the cold climate, and if the temperature in the growing environment is low, it will cause the lotus leaves to dry up, and even frostbite the lotus.

Solution: When the temperature rises above 0 degrees Celsius in winter, pay attention to warm measures.

3. Lack of sunlight.

Reason: The lotus flower is a sun-loving flower, and if it is kept in a place with bad light for a long time, the leaves will also dry up.

Solution: Keep it in a well-lit place and keep it in light for at least 4 hours a day.

It is better to have **, talk about the situation, whether there is a fertilizer before the use of medicine or the weather has abnormal fluctuations.

<> when the growth temperature of lotus flowers is higher than 35 degrees or lower than 5 degrees, it will cause the branches and leaves to wither yellow, so it is good to maintain a suitable temperature, 14-35 degrees. Long-term insufficient or too strong light will cause the leaves to wither and yellow, so keep 7-9 hours of light every day and avoid direct light exposure. If you apply too much fertilizer, the fertilizer damage will be serious, and the leaves will turn yellow, so you should apply fertilizer correctly.

Lotus flowers like to grow in a relatively warm environment, so when the temperature is higher than 35 degrees or lower than 5 degrees, it will lead to yellowing, so it is necessary to maintain a suitable growth temperature of 14-35 degrees throughout the year to promote the growth of branches and leaves, and do a good job of cooling and keeping warm. Funny is suspicious.

Lotus flowers are very fond of light, and if the light is insufficient for a long time, it will cause the leaves to wither and yellow. Therefore, it can maintain 7-9 hours of light conditions every day, which is conducive to the production of photosynthesis and promotes the growth of branches and leaves. When the light is too strong, it is necessary to properly shade to prevent sun exposure.

Lotus is a kind of fertilizer-loving plant, if each fertilizer is too much, it will lead to serious fertilizer damage, and the leaves will appear yellow. Therefore, it is necessary to do a good job in the principle of thin fertilizer and frequent application, and apply fertilizer every half month to promote the growth of branches and leaves.

Lotus has a high demand for water, and if there is a long-term lack of water or serious water accumulation, it will lead to yellowing of leaves. Therefore, it is necessary to water reasonably during the growth period and flower bud stage, which can be watered every 3-5 days, and can be watered without watering in rainy weather.

1. Lack of moisture.

The one-leaf lotus is an aquatic plant, and it cannot survive without water. If it lacks water during the growth process, it will turn yellow, so it should be watered promptly. Regardless of the stage of growth, moisten the soil and pour water in the potting soil as soon as possible to cultivate, so that the leaves will quickly regain their color.

Second, lack of nutrients.

A large part of its yellow leaves are caused by nutrient deficiencies. More nutrients are consumed during the growing period, so it is necessary to supplement fertilizer in time. If you don't fertilize for a long time, the roots can't absorb the proper nutrients and can't provide them to the leaves, and they will slowly turn yellow.

During the growing season, a compound fertilizer solution should be applied every other month, or well-rotted rice washing water can also meet the demand.

3. Lack of light.

Its growth depends on the light of the cult. If left in a dark place for a long time, the leaves will not be able to photosynthesize, and they will slowly turn yellow after a long time. If you want to move to a place with astigmatism, it is good to shade the sun in time when the temperature is high.

It is recommended to put it outdoors in a place with astigmatism, and the ventilation environment is good, which is more conducive to its recovery.

Fourth, infected diseases.

If the environment provided during the administration is not comfortable, such as poor ventilation, insufficient lighting, etc. It is easy to contract yellowing, and the leaves turn yellow. It is necessary to change the maintenance method in time, increase ventilation, and strengthen management. It is also necessary to dispose of the diseased leaves as soon as possible and spray pesticides to prevent diseases.

1. Get more sun.

Specific reason: lotus basking in the sun. If there is not enough light, it will not be able to photosynthesize sufficiently, and the leaves may turn yellow. Solution: Get more sunlight. Plants raised at home can be placed in a sunny place, not in the shade.

2. Supplementary fertilizer.

Specific reasons: The young leaves that have just grown turn yellow, and the old leaves are relatively normal. This phenomenon mostly occurs during the growth period of destruction.

The types of fertilizers that are missing are mostly nitrogen fiber slow local fertilizers and phosphate fertilizers. Solution: An appropriate amount of nitrogen and phosphorus fertilizer should be supplemented, and the concentration should not be too high, and the dosage should not be too large.

3. Add some ferrous sulfate.

Specific reasons: If it is a hydroponic plant, the water quality may be alkaline; In the case of soil-grown plants, the soil may be alkaline. Either way, it affects the plant's ability to absorb trace elements, turning the leaves yellow.

Solution: You can replace it with soil and water, or you can add some ferrous sulfate.

4. Put it in a warm place.

Specific reasons: Plants are not cold tolerant, and the temperature plummets. After freezing, or the temperature difference is too large, the leaves are prone to yellowing. Solution: Keep in a warm place. In addition, you should also pay attention to adjusting the temperature difference, not too large.

5. Prevention and control of diseases.

Specific causes: Threatened by fungal diseases, the appearance of the macula. Solution: carbendazim can be sprayed, but not too much, otherwise it will be counterproductive.
