How do lily leaves turn yellow? learn 6 tricks to solve easily / light, water and fertilizer is the key.

The beauty of lilies is well known, so they are potted at home by many flower friends. However, the lily is a relatively weak plant, once we do not take good care of it, it will have problems, thus showing the symptoms of yellow leaves, what about the yellow leaves of lilies? According to the editor's summary, there are six main reasons for the yellowing of lily leaves. Here are the symptoms and solutions for everyone.

First, how do the leaves of lilies turn yellow? find the cause.

Yellowing leaves is a common symptom of plants, especially potted plants at home, once we do not maintain properly, it will have a problem. As for the lily leaves yellowing how to do, first of all, we have to find the cause of its yellowing, and then solve the problem. In this regard, the editor summed up six points, and attached a solution, let's move on.

II. Causes of yellowing of lily leaves and their solutions

1. Environmental mutation

There are many reasons for the yellowing of lily leaves, and flower friends should first consider environmental problems. If your lilies have just been bought or transplanted, they may not adapt to the great changes in their growth environment, resulting in leaf yellowing.

Solution: ask about the growth environment before the lily, and try to keep it the same, even if you want to change, gradually, let it have a process of adaptation. If the leaves are yellow caused by the environment, flower friends can put the lilies in a ventilated place and wait until the plants return to normal before taking care of them in the normal way.

2. Too much or too little watering

Improper watering is one of the main reasons for the yellowing of lily leaves. If the lily is watered too much or too often, the young leaves of the lilies will turn yellow, but the old leaves of the lilies will turn yellow, but the old leaves of the lilies will turn yellow from the bottom up, even leading to plant death.

Solution: if you water too little, you must immediately pour the right amount of water, of course, not too much at once; when you water too much, as long as you control the moisture in time. It is worth mentioning that too much watering is the most common fault, which will not only lead to yellow leaves of lilies, but also cause rotten roots of lilies to appear, so we would rather water less than more water, after all, lack of water can also make water, too much trouble!

3. Fertilize too much or too little

In the lily culture method, fertilization is very critical, but improper fertilization is also very troublesome, it will cause lily leaves yellowing: when fertilizing too much, the young leaves are thicker and glossy, and the surface will be concave and convex; when fertilizing too little, the young leaves and tender stems turn yellow, and if no timely measures are taken, the whole plant will eventually appear yellow leaves or even die.

Solution: when there is too much fertilization, reduce fertilization or watering to dilute the fertilizer concentration, and change the basin soil in serious cases; when there is too little fertilization, appropriate fertilization, but one-time can not use excessive concentrated fertilizer, otherwise not only can not solve the problem, but also cause root burning.

4. Lack of light

In the growth process of lilies, light is indispensable, once the lack of light, it will reduce the photosynthesis of lilies, resulting in yellowing leaves.

Solution: to increase the light time, it is best to move the lilies outside every morning and evening and bask in the sun for 2 hours.

5. Diseases and insect pests

When it comes to the yellowing of lily leaves, diseases and insect pests can not be ignored. If the leaves are yellowed by pests, insecticides should be sprayed immediately; if caused by bacteria, antibiotics should be used. What kind of medicine should be sprayed is introduced in detail in the pest control of lilies, so I won't say much here.

6. Iron deficient yellow leaves

If the above points are excluded, then the leaves of lilies turn yellow and it can only be due to iron deficiency. Under some special circumstances, once the iron content of the lily is insufficient, its leaves will turn yellow. Symptoms: the mesophyll of the young leaves is yellow and the veins are reticulate.

Solution: spray ferrous sulfate solution and mix it with a cake fertilizer: ferrous sulfate: water ratio of 7 to 5: 200, which is said to have a wonderful effect on the treatment of iron deficiency yellow leaves.

Generally speaking, lilies are easy to raise, but because many people do not control light, water and fertilizer in place, it will affect plant growth, resulting in a variety of problems, and leaf yellow is only one of them. With regard to the yellowing of lily leaves, the editor has introduced this. I hope you can remember the method and solve this kind of problem smoothly.

Culture method of Gardenia jasminoides the leaves of Gardenia jasminoides are yellowing and not blooming.

In the flowers, gardenia is undoubtedly one of the more familiar flowers, people like to breed at home, but many people do not know much about the breeding methods of gardenia, resulting in a lot of problems in the breeding process, such as yellowing leaves, not blooming and so on. Today, the editor introduces the breeding methods of gardenia and the reasons why gardenia leaves are yellow and do not blossom.

(gardenia is planted in the courtyard and has a strong ornamental effect.)

Gardenia grows like one in the four seasons, the leaf color is evergreen, the fragrance is elegant when blooming, and the white flowers are white, which is particularly beautiful and very attractive. It is often used for potted plants in courtyards and balconies. It has strong environmental adaptability, can grow well in these places, and has strong decorative and ornamental effects. The following editor will talk about the cultivation methods of gardenia from the various characteristics of gardenia.

First, sour soil culture, gardenia need scattered light, so like sour soil, if the soil is alkaline, it will make gardenia can not absorb iron very well, which has a great impact on the formation of chlorophyll, and further cause flower branches to wither and even die; so the soil must use loose, fertile acid soil, you can also add some substances with such effect.

(gardenia has a good decorative effect)

Second, put in a cool place, gardenia must not be exposed to the scorching sun, otherwise the leaves will be withered and yellow, but it does not mean that it should be put in the whole shade, because it has a certain demand for light, it is best to keep 60% of the light every day, in addition, after entering April, fertilizing should be carried out twice a month.

Third, the air humidity, gardenia like to be wet, so the air can not be too dry, according to expert statistics, if the air humidity is less than 70%, it will affect the normal opening of flowers, but if it is too wet, it will cause rotting roots and yellow leaves, so in addition to normal watering, we should often spray clean water nearby. Another problem we should pay great attention to is that water should not be watered too much, otherwise it will also affect growth. So how to water gardenia?

A, when you see the soil is dry, knock on the flowerpot with your hand. If there is an empty sound, it needs watering. The bottom of the flowerpot starts to leak and stops. It is better to add some eggs and soy milk to the watering water, which is more conducive to growth.

(gardenia in full bloom, different beauty)

Fourth, fertilization tips, gardenia like fertilizer, but can not add too much fertilizer at one time, must be thin fertilizer, must not save trouble, otherwise it will cause thick branches, big leaves, thick green, it will lose its own appreciation effect.

Fifth, temperature requirements, the growth temperature of gardenia can not be too low, because it likes temperature, generally speaking, the temperature of the growing period is 18 to 22 degrees, 5 to 10 degrees in winter, and frostbite if it is less than 10 degrees below zero, which should be paid special attention to in the north.

Sixth, proper pruning, gardenia is very easy to grow luxuriant branches, and cause airtight and disorganized feeling, which will cause nutrition dispersion and poor ornamental, so it is necessary to prune it, it is best to choose three main branches when pruning, and cut off the roots and tillers to sprout new branches at any time, and the branches should be truncated in time after the flowers are shedding, so that new branches will sprout under the cut. When the new branch grows three nodes, it is necessary to pick the heart so as not to grow blindly.

(put the gardenia in the sun.)

Seventh, disease prevention, we usually see four kinds of gardenia diseases:

A, iron deficiency, which is the most common, iron deficiency will cause the formation of chlorophyll, and then make the leaves lose green, when you can use ferrous sulfate water and low concentration of black alum water, three times a month.

B, magnesium deficiency will lead to yellow veins of the lower old leaves of Gardenia jasminoides, so it is necessary to spray with low concentration of magnesium sulfate solution.

C, the soil is too wet or too dry, this can be seen in the third point

D, the sun exposure, this can refer to the second point.

Eighth, breeding methods, Gardenia jasminoides generally have two propagation methods: cutting and striping

A, cuttings, 15 cm long with twigs in the rainy season, planted in the seedbed and rooting in 12 days.

B, in April, biennial branches were selected, which were 2O-25 cm long, buried in the soil and kept moist, about 30 natural roots were separated from the mother plant in summer and planted in the next spring.

The reason for the yellowing of the leaves of mast flower

First, improper moisture

A, too much watering, in this case, the tender leaves of the masts are dark yellow and dull, but there is no obvious change in the old leaves, so just take the flowers out of the pot and put them in a cool, ventilated place and put them back after the soil dries.

B, lack of water, leaf tip or edge withered, dry, old leaves withered and yellow shedding from bottom to top, but the growth of new leaves is relatively normal, at this time should be fully watered and thoroughly watered.

(there are many reasons why gardenia leaves turn yellow.)

Second, improper lighting

A, the light is too strong, the sunrise part of the leaf appears macula, at this time only need to move it to the shade to maintain can be restored, the new leaves will no longer have macula.

B. when there is not enough sunlight, the leaves will turn yellow or even fall off, as long as you put them in the sun to replenish the sun.

Third, improper fertilization

A, excessive fertilization, mainly manifested in the brown appearance at the tip of the new leaves, the thickening and dullness of the leaves, and the scorched yellow shedding of the old leaves. At this time, it is necessary to stop fertilization immediately, and in serious cases, the soil should be washed to reduce the concentration. B, insufficient fertilizer will also cause plant yellowing, such as iron deficiency, the leaves are light yellow or white, and the leaf veins are still green, so it is necessary to spray 0.2% Moe 0.5% ferrous sulfate for prevention and control; magnesium deficiency, the old leaves turn yellow first, then the new leaves turn yellow, and the leaf veins are still green. At this time, 0.7%-0.8% boron and magnesium fertilizer can be sprayed to prevent and control.

Fourth, the temperature is too low, too low temperature will also cause leaf yellowing, as long as it is moved into the high temperature.

The reason why the mast flower does not bloom

First, improper water and fertilizer, once excessive, it will cause plant overgrowth, reproductive growth without enough nutrients will affect the formation of flower buds, resulting in no flowering or few flowering, some blooming, or even immediately fall off. In the period of flower bud differentiation, special attention should be paid to the collocation of phosphorus and potassium fertilizer, such as 0.2% potassium dihydrogen phosphate solution, which is conducive to flower bud formation and bud pregnancy; excessive fertilization and watering during the bud period will also cause falling flowers and seedlings.

(gardenia hasn't blossomed all the time, so be careful.)

Second, the light is not suitable, Jiaozi flowers like shade, we should pay special attention to the strong light in summer and too weak light in winter, too strong and too weak will affect the blossom.

Third, the soil contains high alkali, Jianzi flower likes acidic soil, cultivated mast flower soil contains high salt and alkali, it will cause plant yellowing, and eventually affect flowering.

Fourth, no pruning and shaping, messy masts and branches, a large number of miscellaneous branches consuming a lot of nutrients and branches too dense, affecting photosynthesis, are all important reasons for not flowering.

Fifth, diseases and insect pests are serious. I believe everyone can understand that serious diseases and insect pests are bound to lead to the loss of flowers.

What measures should be taken after smooth sailing and yellowing leaves?

Content Abstract: plain sailing, the scientific name is white crane taro, recorded in the "Araceae", for angiosperms, aliases as bract taro, white palm, lily intention, etc., planting is more complex, what measures should be taken after smooth sailing leaves yellowing? [plain sailing leaves yellowing]

Cause of yellowing

Waterlogging: smooth sailing for temperate plants, daily excessive watering, resulting in stagnant water in the basin, leaves will appear yellowing phenomenon, at this time diseased and tender leaves, more than a year old leaves have no obvious change, while new branches and leaves, first atrophy, then yellow, and eventually wither, will also affect the whole plant.

Drought: the leaves yellowed due to lack of water, mostly showed that the edge of the leaves withered and dried, but mostly affected the old leaves, began to wither and yellowed from the bottom up, and the new leaves did not change in a short time.

Burns: sufficient light absorption, maintenance time under the scorching sun for too long, will also cause yellow leaf phenomenon, because smooth sailing for shade plants, and too much light, it will be because of its flowers, occupation withered, dry, the first performance of the leaf macula, can be transferred, but also contagious. But at the same time, due to the lack of daily light, it will also cause the leaves to turn yellow now, mostly for the whole plant leaves turn yellow, and then fall off.

Fat and strong: the reason for the yellowing of this kind of leaves is mostly because the daily pruning is not in place, resulting in branches and leaves too dense, while the root system and rhizome center do not get enough nutrients in time, and the leaves are lack of green, resulting in yellowing and shedding.

Undernutrition: lack of nutrition, mostly because of daily water and fertilizer reasons, due to lack of fertilizer will be shown as the new leaf color lighter, no freshness, the color will also change from green to yellow.

Disease and insect injury: smooth sailing and planting, the most common disease is leaf spot disease, and leaf yellowing is caused by disease pests, anthrax, brown spot and so on, mostly because of inducing the parasitism of scale insects, after absorbing smooth flowers and leaves, the virus is transmitted, and after the leaves turn yellow, most of them die. Solution method

1. After the leaves turn yellow, we should first observe whether the rotten roots have appeared, while those with serious illness need to change the soil and basin, because after the rotten roots appear, the soil can no longer provide nutrients, and the roots are difficult to breathe, but after changing the soil, it is necessary to avoid direct sunlight, and the soil should be kept loose.

two。 The cause of plant yellowing can be judged. If the growth is too dense, the ramet method can be adopted directly, which can not only improve the yellowing phenomenon, but also achieve the purpose of reproduction.

3. However, the yellowing of plants is too serious, which is caused by infectious diseases, so it is suggested that they should be discarded. This phenomenon is difficult to improve even if the soil and pots are changed.

4. Smooth sailing leaves turn yellow, because the environment is too dry, you can use foliar watering to water the roots in a short time, or you can wrap the yellowing leaves in plastic bags, but when the climate is right, you need to open them for plants to breathe. In this way, because of the internal temperature and height after the package, it has a certain inhibitory effect on foliar disease.

5. If the yellowing phenomenon occurs at the leaf tip due to the lack of soil nutrition, the soil can be changed, and nutrient elements can be applied to the soil to reconcile the acidity and basicity of the soil. After the plant nutrition is absorbed, the yellowing phenomenon can be avoided.

6. The yellowing phenomenon of leaves caused by too much light should be found in time, and it should be moisturized, transported indoors, or directly protect the leaves from the hot sun. However, if it is still placed in the hot sun for a long time, the yellowing of leaves will be aggravated, resulting in death.

7. Timely improve maintenance details, such as fertilization, avoid contact with agricultural fertilizer, raw fertilizer and so on, and after applying solid fertilizer, water should be irrigated in time, and fertilizer can also be diluted and irrigated, which is not only conducive to absorption. it can also improve the yellowing of smooth sailing leaves caused by improper fertilization.

8. Yellow leaves caused by scale insects often appear yellow spots on smooth sailing leaves. At this time, you can choose to use carbendazim, which can be diluted directly and sprayed with appropriate amount, which can help remove diseases and pests and play a preventive role. Prevention method

1. During daily maintenance, scientific application of water and fertilizer should be adopted to avoid plant pathological changes due to excessive and insufficient water and fertilizer. at the same time, smooth sailing is suitable for mild light, strong sense of light, and easy to form burns.

two。 From May to September every year, plain sailing plants will turn yellow because the environment is too dry, so it is necessary to keep the soil moist and spray water on the surface to avoid deep watering, while fertilization should be kept twice a month until November. It is necessary to move the plants indoors to avoid going out for the winter.

3. Learning the correct method of plain sailing cultivation and paying attention to daily details can avoid the phenomenon of pathological changes, death and yellowing of leaves due to incorrect maintenance.

Summary: smooth sailing leaves yellowing reasons, solutions, and prevention methods are introduced as above, we should pay attention to the daily planting environment, secondly, pay more attention to planting skills, more conducive to growth.
