What is the cause of yellowing and withering of flowers and leaves Causes of yellowing and withering

The reasons why the leaves of plants turn yellow and dry are as follows. 1. Lack of sunlight: If the plant is kept in a shady place for a long time, the leaves cannot form chlorophyll and nutrients, so they turn yellow or even dry up and fall off.

2. Improper watering: the root system is anoxic and rotten, which affects the transportation of water nutrients to the leaves, resulting in poor leaf growth.

3. Excessive fertilization: Excessive or too concentrated fertilizer is applied to the plant during maintenance, and fertilizer damage occurs.

1. If the light is too strong, the tips of the flowers and leaves are yellow and dry, and it is likely that the light is too strong and the sun is too strong. Although most flowers and plants love light, they are not sun-tolerant. If you are exposed to strong light for a long time, you are likely to get sunburned, and the tips of the leaves will turn yellow and wilt at the beginning.

It should be shaded as soon as possible, moved to a place of astigmatism in summer, and sprayed with water appropriately, which will help it recover as soon as possible.

2. Improper watering, if improper watering during the maintenance of plants, it may also lead to yellowing and wilting of the leaf tips. Frequent watering or overwatering, the plant can not absorb all of them, and after a long time, it will hinder the respiration of the root system, and the leaf tips are easy to turn yellow. It should be drained as soon as possible, loosen the soil, and evaporate the water.

If you forget to water for a long time, it will not work, and there will be a drought and yellow situation. In this case, it is necessary to replenish water as soon as possible to make the soil slightly wet.

3. The soil is unsuitable, the leaf tip is yellow and dry, or it may be that the soil is unpleasant, and the soil is not changed for a long time, the soil is seriously compacted, which hinders the respiration of the root system, and the leaves will be yellow and dry after a long time. In this case, it is recommended to change the soil as soon as possible, and loosen the soil first if the environment is not suitable to promote the normal respiration of the root system and absorb fertilizer and water.

4. Infected with pests and diseases, the tips of flowers and leaves are yellow and dry, and it may also be infected with pests and diseases, and the environment provided is not suitable for infection with pests and diseases. Once found, the part of the pest and disease should be cut off as soon as possible, and the bactericidal agent should be sprayed to avoid further deterioration. In addition, it is necessary to change the environment in the later stage, especially to control the temperature and humidity.

The reasons for the yellowing and dryness of the leaves of the flowers are long-term watering, lack of water or too little watering, too much fertilization or too large concentration, only watering without fertilizer, etc., due to long-term watering caused by the yellow leaves of the leaves are manifested in the young leaves Yang Huang annihilation is dull, and the old leaves have no obvious changes.

Due to lack of water or less watering, the leaves are yellowed, which is manifested in the old leaves withering and yellowing from bottom to top, but the new leaves generally grow normally. Due to too much fertilization or too much concentration, the top of the new leaves appears dry brown, and the tips of the old leaves are dry and scorched and yellow and fall off, although the general leaf surface is thick and shiny, but most of them are uneven.

1. The leaves of the flowers are yellow and dry and pointy, mainly due to the following three points.

2. The first is water yellow, too much watering causes water to rot the roots, and the leaves of the plant will turn yellow and wilt if they cannot absorb nutrients.

3. The second is light, long-term strong direct light will cause plant leaves to burn, serious water loss, insufficient light affects photosynthetic plants, and the leaves will also be yellow.

4. The third is improper fertilizer, excessive fertilization or application of unrotted fertilizer will cause the leaves of the flowers to turn yellow and dry tips.

The flowers and leaves are yellow and dry, it may be that the light is too strong, causing the flowers and leaves to be burned by strong light, and it is necessary to do a good job of shading measures for the plants, or it is possible that the flowers and leaves are watered and rotten, and they need to be watered every three days to keep the soil moist, and it is also possible that there is less fertilization, resulting in malnutrition of the flowers and leaves, and it is necessary to fertilize every other month.

1. Shade in time

When cultivating plants, if they are exposed to strong light, it will cause the plants to be sunburned, which will make the flowers and leaves dry and yellow, and it is necessary to immediately do shade measures for the plants, and it can also be moved to a ventilated semi-shaded environment for maintenance, and it is necessary to use scissors to cut the dense flowers and leaves to strengthen the circulation of air.

2. Control watering

When raising plants, if you water too much, it will lead to water accumulation in the soil, so that the root system of the plant does not breathe well, which will cause the flowers and leaves of the plant to turn yellow and dry, you need to stop watering immediately, and put the plant in a cool and dry place to dry, wait for the soil to dry completely, and then water every three days.

3. Sufficient nutrients

Mosaic leaves need sufficient nutrients in the growth process, if the nutrients are insufficient, it will lead to plant malnutrition, so that the mosaic leaves are yellow and dry, need to increase the number of fertilization, fertilizer can choose nitrogen, phosphorus and potassium compound fertilizer, provide the required trace elements for the mosaic leaves, so that the mosaic leaves can grow vigorously.

4. Maintenance management

Mosaic leaves in the maintenance, need to regularly observe the growth of the plant, if you find the mosaic leaves on the traces of pests crawling, you need to immediately carry out manual insect removal, wipe off the pests with paper towels, also need to use scissors to cut off the diseased leaves and yellow leaves, and spray insecticides every other week, after a period of time can get rid of the pests.

1. Lack of light; The leaves of many plants are easy to yellow, and they don't know what the reason for the yellowing of the leaves is, it is likely to be caused by a lack of light, and if they do not get enough sunlight, they will not be able to photosynthesize, and they need to be moved to a well-ventilated and sunny place immediately for careful maintenance.

2. The temperature is too low; There are some plants in life that are more cold-resistant, and there are also plants that are afraid of cold, and eventually they will frostbite the plant, make the leaves of the plant yellow, and may even cause death, if it is caused by too low temperature, it needs to be controlled at a temperature suitable for growth, and it should be given enough light to restore the health of the leaves.

3. Improper water and fertilizer; Each plant has different requirements for watering and fertilization, if the watering and fertilization are improper, it will cause damage to the roots of the plant, resulting in the inability to consume water and nutrients normally, and finally lead to the yellowing of the leaves.

4. Pests and diseases; There are many reasons for the yellowing of leaves, in addition to improper maintenance, it may also be suffering from pests and diseases, it is necessary to cut off all the diseased leaves immediately, move them to a ventilated place, strengthen management, and spray insecticides, carbendazim and other agents to control pests and diseases.

The yellowing and withering of flowers and leaves may be due to too much watering, dry damage, excessive fertilization, etc.

1. Watering too much

Potted plants will have wilted, dull and even rotten leaves. After discovering this situation, it is necessary to pour the plant soil out of the pot and put it in a cool and ventilated place indoors, so that the saturated water in the soil can be dissipated, and the air permeability can be enhanced, so as to quickly restore the normal activities of the root system. At the same time, spray a little water onto the foliage.

to reduce the consumption in its body. In this way, the plant will recover after three to five days. After restoration, repot with new soil.

2. Dry damage

Due to business trips, leakage of watering or drought climate, the potting soil is dehydrated and completely dry. Once this situation occurs, be sure not to water a lot of water immediately, water thoroughly, step by step, water slowly, you should move the pot to a semi-shaded place first, and then water a little to make the pot soil moist, at the same time, spray some water on the leaf surface, and wait until the stems and leaves are all erect, and then water through the water into normal maintenance.

3. Excessive fertilization

If you find that the potted plants have just been covered with thick fertilizer or too much fertilizer, you should immediately water the potting soil with water to dilute the diluted fertilizer solution, and put the potted plants in a cool place to allow them to regrow.

If the leaf wilts and turns yellow because of the serious fertilizer damage, a part of the yellow or wilted leaves should be pruned first. Then pour the flowers out of the pot, remove some soil, then rinse with water, cut off part of the roots, if there are rotten roots, to cut off thoroughly, to prevent continued decay, and then use sand to re-pot, water thoroughly, put under the shade for maintenance, and then carry out normal maintenance after recovering vitality.
