How to deal with yellowing of plant leaves?

Friends who cultivate flowers and plants are not uncommon for the yellowing of plant leaves. Why do the leaves turn yellow? There are three main reasons, too much watering, stagnant water retting roots, lack of light, lack of element yellowing. How can we solve the problem of yellowing of leaves? Let's take a look at it with the editor.

Using ferrous sulfate to improve soil

In one case, there is no shortage of all kinds of elements in the soil, but plants are still deficient in yellowing. There are two reasons:

One is the lack of these elements in the soil. Organic matter is the main source of trace elements in soil, long-term non-fertilization or only the use of inorganic fertilizers, the gradual decrease of organic matter, will lead to the lack of trace elements. If this is the case, increase the application of organic fertilizer. Flower friends with strong hands-on ability can use a variety of kitchen waste to ferment and rett to produce organic fertilizer. If the conditions do not permit, you can buy all-element organic nutrient solution.

There is also a situation that although there is no shortage of various elements in the soil, but the PH value is too high, soil salinization of various elements solidified into substances insoluble in water, plants can not absorb, over time, there will be symptoms of element deficiency yellow leaves.

If watering, long-term use of water with high hardness, it is easy to occur. At this time, ferrous sulfate can be used to improve the soil and reduce the PH value.

Supplement iron to solve the problem of yellow leaves

Iron deficiency in plants will lead to yellowing of leaves, and yellowing will occur when the content of iron in the soil is too low to supply plants. If the plant is yellowed by iron deficiency, 0.2% ferrous sulfate solution can be used to irrigate roots and spray leaves to supplement iron. As divalent ferrous ions are easy to react to trivalent iron ions in the air, it is difficult for plants to absorb trivalent iron ions, so ferrous sulfate solution should be used now.

To sum up, it can be seen that ferrous sulfate plays an important role in plant growth, and there are two main functions of ferrous sulfate: improving soil and replenishing iron. Therefore, in order to solve the leaf yellowing caused by iron deficiency, we can consider using ferrous sulfate.

How to deal with the yellowing of the bottom leaves of succulent plants? The yellowing of the bottom leaves of succulent plants is a problem that many people encounter in the process of raising meat, so can such leaves be ripped off in the end? Zuihua net told you today, in fact, the peripheral leaves slowly one by one, a circle of killing is a natural phenomenon, but why there is such a phenomenon? First of all, in order to prevent the succulent plants from becoming succulent, we do not give much water. If we water the succulent plants every few days, then the leaves below him will certainly not turn yellow, and they will always be so full. Not only will they lose their shape, but they will also continue to grow taller, and some will wear skirts, because there is no room for the new leaves above, and if the leaves below are not consumed, they can only continue to push down. Of course, in many natural environments, succulent meat can not absorb much water, which is why succulent meat stores water in its leaves for future use. Cactus is a very good example. But we don't have much water, so what if they are short of water? That is naturally to absorb water from their own leaves, so as to continue to survive. In fact, the water inside the yellowing leaves has not been fully absorbed, in fact, there is still a lot of water for succulent absorption, if we pull out the leaves at this time, then the plant will have to find a place to absorb water again. Secondly, those withered and yellow leaves actually store some nutrients. Don't underestimate those soft yellowing leaves, sometimes one or two leaves are useless, but over time, a lot of nutrients are wasted. In addition, the nutrients needed by succulent plants are not needed. The nutrition he produces is enough for his own use, so pulling him out is a waste. So when will it be unplugged? And in this case, it can be removed. It can be seen clearly that although the leaves are still a little soft, they have actually dried up. In fact, at a certain stage, the old leaf can be pulled out so that it does not affect its beauty, but to make sure it is not the right time. Under normal circumstances, after the nutrients in the leaves are completely absorbed, the leaves left behind will eventually become thinner and dry, and the older ones will even break as soon as they are touched (usually appear in the exposed succulent body). Of course, we don't have to wait for a touch to break it off, but there's no hurry. Through the detailed introduction of this article, I hope that flower friends can correctly deal with the yellowing succulent plant leaves. Welcome to continue to pay attention to the more information of Zuihua net! The reason and solution of flower plant leaf yellowing is the most common problem we encounter in the process of flower cultivation. A pot of flower leaves slowly turn yellow and wither. I don't know what the reason is. In fact, there are many reasons for the yellowing and falling of the leaves, some of which are natural phenomena of the plants themselves, and the leaves can be cut off after completing the mission, while some plants have the phenomenon of yellowing leaves in the normal growth cycle, which needs to attract our attention. and carefully find the reason to prescribe the right medicine. The causes and solutions of yellowing of leaves (1) too much watering, long-term over-wet basin soil, resulting in lack of oxygen in the soil, causing part of the fibrous roots to rot, hindering normal respiration and absorption of water and nutrients, causing leaves to turn yellow and fall off. After the injury, the young leaves turn pale yellow, and then the old leaves gradually turn yellow. watering should be controlled immediately, fertilization should be suspended, and the soil should be often loosened to make the soil well ventilated. (2) drought and dehydration. Flower cultivation leakage watering or long-term watering half waist water (that is, upper wet and lower dry) will affect nutrient absorption, and it is also easy to cause dull and dull leaves and drooping leaves. First, the lower old leaves aged, and gradually withered and yellowed off from the bottom up. At this time need a small amount of watering and spraying, so that it gradually recovered and then transferred to normal watering, (3) long-term fattening. There is no application of ammonia fertilizer or no change of soil for a long time, and there is a lack of nitrogen and other nutrients in the soil, resulting in thin branches and leaves and thin and yellow leaves. It is necessary to pour the pot in time and gradually apply rarefied mature liquid fertilizer or compound flower fertilizer into new loose and fertile culture soil. (4) excessive fertilization. If you fertilize too much, the new leaves will be thick and uneven, and the dry tips of the old leaves will fall off. You should immediately stop fertilization and increase the amount of water to make the fertilizer flow out from the drainage hole at the bottom of the basin, or immediately pour the pot, rinse the soil block with water and then plant it again into the basin. (5) hot and high temperature. In summer, if you put cool flowers (such as cyclamen, Golden Bell upside down, four Seasons Begonia) in a high temperature place to let the strong light shine directly, it is very easy to cause the young leaf tip and leaf edge to scorch, or the leaf yellow to fall off. Move to a well-ventilated shady place in time. (6) excessive shading. If the sun-loving flowers are kept in shade or lack of light for a long time, it will cause the branches and leaves to grow, the leaves are thin and yellow, and they do not blossom or rarely bloom. Be careful to move the flowerpot to the sunny place. (7) soil and water is alkaline. There are more saline and alkali in soil and water in most areas of northern China, and flowers with acid-like soil are planted, such as rhododendron, camellia, Michelia, gardenia, orchid, magnolia, sweet-scented osmanthus and so on. Due to the lack of soluble iron and other elements that can be absorbed by the soil, the leaves will gradually turn yellow. Acid soil should be selected when planting, and alum fertilizer and water should be often watered during the growth period. (8) whether it is airtight or not. If too much nitrogen fertilizer is applied, the branches and leaves will grow luxuriantly, coupled with the long-term unpruned, resulting in insufficient light in the inner chamber branches and leaves, which is easy to cause the leaves to yellowing and falling off. Reasonable fertilization should be applied and pruning should be strengthened to make it ventilated and transparent. (9) dry air. When the indoor air is too dry, some flowers that like the humid environment, such as hanging orchids and orchids, often appear leaf tip dryness or leaf edge scorching and so on. Attention should be paid to water spraying, plastic film cover and other methods to increase air humidity, (10) improper temperature. If the room temperature is too low in winter, the flowers are often vulnerable to cold damage, which leads to the yellowing of the leaves and death in severe cases. If the room temperature is too high, the transpiration of the plant is too high, and the root water and nutrients are in short supply, the leaves will turn yellow. Please pay attention to adjust the room temperature in time. (11) the soil is sour. It is easy to lose acid and magnesium in southern red loam. planting flowers and trees with alkali-tolerant or mute soil, such as oleander, yellow poplar, Yingchun, etc., are often prone to green and yellowing between the veins of old leaves. Can apply calcium magnesium phosphate fertilizer or spray magnesium sulfate solution. Through the detailed introduction of this article, I hope you can gain something!
