Why the leaves of Tripterygium wilfordii turn yellow, caused by light / watering / fertilization (with solutions)

Whenever the fragrant vine blossoms, it is always intoxicated with the splendor of more flowers than leaves, but the premise to enjoy these is to know the breeding methods and matters needing attention, otherwise the leaves may turn yellow. so why do the leaves turn yellow? What should we do if it turns yellow? This article focuses on these two aspects.

Why the leaves of the fragrant vine turn yellow

Before exploring why the leaves turn yellow, we need to know the most suitable growing environment, which is warm, moist and well-lit. At the same time, the temperature of 20-31 degrees is the best, and the highest temperature should not exceed 35 degrees. The lowest temperature should not be less than 10 degrees, otherwise the leaves may turn yellow. Here are some reasons and treatment measures that will lead to the yellowing of leaves.

I. watering

1. Caused by too much watering

Reason and phenomenon: we know that regardless of any plant, watering should be moderate. If the vine is watered too much, it will appear the following phenomena: the new leaves are yellow and have no luster; the old leaves are very normal; the branches are small and a little yellow; the new shoots are shrunk, why are the leaves yellow at this time? The reason is that there is too much water and the phenomenon of water yellow appears.

Treatment measures: remove the fragrant vine from the basin, then put it in a cool place to dry and then put it back into the basin, after that, you need to pay attention to the amount of watering is not too much.

2. Too little watering

Reason and phenomenon: when we find that the leaves of the vine turn yellow, and the tips and edges of the leaves become dry, and the old leaves turn yellow and fall from the bottom to the top, at this time we can judge why the leaves of the vine turn yellow because there is too little watering, which makes the vine dry.

Treatment measures: pay attention to watering, each watering needs to maintain a sufficient amount, but need to be careful not to water Thailand frequently, otherwise the phenomenon of water yellowing may occur.

II. Fertilization

1. Apply too much fertilizer (fat yellow phenomenon)

Phenomenon and reason: if the top of the newly grown leaves of Piaoxiang vine appears dry brown, and the leaves look very thick but lack of luster, and the phenomenon that concave and convex can not be expanded at the same time, it belongs to fat yellow at this time, why are the leaves of Piaoxiang rattan yellow at this time? The reason is caused by too much fertilizing.

Treatment measures: stop fertilization, check whether the concentration of fertilizer is too high, if it is a serious leaf yellowing phenomenon, then we need to use a lot of water for cleaning, but it should be noted that the water should be drained after cleaning.

2. Too little fertilization (lack of fat and yellow)

Phenomenon and reason: the color of the new leaf looks very dim, there are more yellow or light green, although the old leaf color is normal, but will gradually change from green to yellow, this phenomenon is called lack of fat yellow, why do the leaves of fragrant rattan turn yellow? The reason is the lack of fertilizer.

Treatment measures: check the dry knot of earthwork, if it is necessary to change the soil, and increase the frequency of fertilization, but not too much each time, and add some alum when applying fertilizer.

Third, lighting

1. Excessive light (burning yellow)

Phenomenon and reason: when it is found that the tips and edges of the leaves have withered, and there are yellow spots on the leaves facing the sun, this situation is burning yellow because the light is too strong.

Treatment measures: avoid the stronger sun directly shining on it, while moving the fragrant vine to a more cool place.

2. Too little light (lack of light and yellow)

Phenomenon and reason: the leaves of the plant slowly turn yellow and begin to fall off. Why do the leaves of the fragrant vine turn yellow at this time? The reason is that the vine has been in a dark place for a long time and lacks light.

Treatment measures: fill the light to the fragrant vine, or move it to a place where the light is relatively sufficient, and the yellowing of the leaves will be alleviated.

Conclusion: the main reasons for the yellowing of leaves are fertilization, watering and light. Don't panic when the leaves are yellowing, look for the corresponding causes for different phenomena, but take reasonable measures to improve the symptoms of yellowing of leaves.

How to raise the fragrant vine in winter? can the vine survive the winter outdoors in winter / stop fertilizing

It is well known that the most suitable temperature is 20-31 degrees. However, in most parts of China, the winter temperature is not within this range, so can the vine survive the winter outdoors? The answer is yes, raising fragrant vines in winter will be slightly different from other seasons, but in addition to understanding the breeding methods and points for attention, we also need to know how to raise fragrant vines in winter.

How to raise the fragrant vine in winter

Although we know that the lowest temperature of Piaoxiang rattan culture should not be lower than 10 degrees, because too low temperature may cause freezing damage, we will find that the temperature is often lower than 10 degrees every winter, so many people want to know whether Piaoxiang vine can survive the winter outdoors. The answer is that if you know how to raise fragrant vines in winter, you can put them outside.

I. temperature control

Because we can't control the outdoor temperature in winter, but the indoor temperature can be adjusted, so it is necessary to control the temperature if we want to make the vine safely through the winter. for friends in the north, how to raise them in winter? Try to put it indoors and in a well-ventilated place.

If you are in the south, raising fragrant vines in winter will depend on the situation to decide whether to put them indoors or outdoors, because the temperature difference between indoor and outdoor in the south is not obvious, so can fragrant vines survive the winter outdoors in winter? The answer is yes, but only if reasonable measures are taken, such as putting fragrant vines outdoors in Hangzhou, but covering a few plastic bags and leaving air holes to prevent them from freezing.

2. Control of watering

1. Due to the change of climatic conditions, the watering method in spring, summer and autumn is not suitable for winter. How to raise fragrant vines in winter? It's crucial in watering. It should be noted that the amount of water in winter should not be burned as far as possible. It is not too late to water the basin soil when it is found to be dry. If the basin soil is not dry at all, do not water it.

2, each time the amount of water should not be too large, do not let stagnant water appear in the basin, if you find that the basin soil is slightly moist, you should stop watering, you can put it in the light for maintenance.

III. Fertilization control

1. We know that one of the reasons why the leaves turn yellow is caused by fertilization, so how to fertilize the leaves in winter in order to prevent the leaves from yellowing? The answer is that fertilization should be stopped in winter.

2. The fragrant vine can enter dormancy in winter, and at this time we should stop fertilizing to let the vine go dormant. If we continue to apply fertilizer, the leaves and roots of the plant will grow. On the contrary, there will be the possibility of frostbite on new branches and leaves.

Fourth, lighting control

Although the winter fragrant vine into dormancy growth is slow, but at this time it is inseparable from the light, then at this time how to raise the fragrant vine in winter? You can put it on the balcony or windowsill where there is plenty of light.

What kind of soil is used to plant fragrant vines? what if the leaves turn yellow?

Then what kind of soil is more suitable for planting fragrant vines? What if the leaves of the fragrant vine turn yellow? Let's learn about it next.

First, what kind of soil is used to plant the fragrant vine

Indoor pot cultivation in the north can use rotten leaf soil with a small amount of coarse sand, the south can use pond mud, peat soil, river sand mixed at 5:3:2. During the growing period, an appropriate amount of compound fertilizer 3Mel can be applied for 5 times, but the amount of nitrogen fertilizer should be controlled to avoid excessive vegetative growth and affect reproductive growth and reduce flowering. In the process of maintenance, watering should be properly controlled to form a developed root system.

Second, what if the leaves of the fragrant vine turn yellow?

1. Dry yellow: the yellow with lack of water is different from the yellow with more water, the yellow with lack of water is withered or dry at the tip or edge of the leaf, and the old leaves wither and fall off from the bottom up, but the growth of the new leaves is relatively normal. Pay attention to watering enough and thoroughly.

2. lack of fat yellow: the color of the young leaves becomes lighter, yellow or light green, while the old leaves are more normal or gradually change from green to yellow. To often check the basin soil if there is a dry knot phenomenon should change the soil, usually apply thin fertilizer frequently and timely pour some alum water to supplement iron.

3. Light yellow: if the leaves are placed in a shady environment for a long time, the leaves can not get enough sunlight and can not form chlorophyll, and the whole leaves turn yellow and fall off. Supplementary light can avoid the disease.

4. Fat yellow: flowers yellowing caused by too much fertilization or too much concentration, showing dry brown at the tip of new leaves, general leaf thickening and no luster, and concave and convex not stretching, old leaves scorched yellow shedding. Fertilizer should be stopped immediately and some fertilizers should be washed with a large amount of washing.

5. Burning yellow: the strong sun shines directly on some shade-loving flowers (such as hanging orchids, hairpins, etc.), which is easy to cause withered leaf tips and leaf edges, and macula appears in the sunny part of the leaves. Just move to the shade.

6. Water yellow: the young leaves are dark yellow and dull, the old leaves have no obvious change, the branches are small and yellow-green, and the new shoots are not long, indicating that they are overwatered. Remove the flowers from the pot and place them in a ventilated, cool, self-drying soil mass and then put them back into the basin.
