Is the yellowing and curling wilting of clematis leaves caused by blight?

The first reason for the curling and drying of the leaves is improper watering, we raise clematis generally with more breathable and permeable soil, try not to use too large pots for cultivation. In the case of unnatural ventilation in the room, water the Duo soil frequently, and before the soil is dry, watering immediately will cause the roots to rot, which will cause the leaves to curl and wither. If you forget to water clematis, you forget to water the roots.

The leaves are also quite dry. Plant clematis, please control a watering method. Generally, earthwork excavation, one or two cm drying, and immediate watering is enough.

It will not rot because of rotten roots, nor will it wither due to curling of leaves.

The second situation is caused by fertilizer damage, for example, we raise clematis to fertilize it too often. For example, I raise clematis. If the fertilization frequency is too high and the fertilization concentration value is too high, the roots will be burned.

Just like if we use a chemical fertilizer with a high concentration value, if you spray it on the leaves immediately, the leaves will become hard and curly. The fertilization of clematis should be well controlled. It is a thick root, not a capillary.

If we apply fertilizer properly, the concentration value should go down. If the frequency is high, 2 or 3 times a month for him is enough. When spraying leaves, the concentration values also need to be reduced.

Never spray too often. The nutrient supply is sufficient, and the roots and leaves will not be roasted.

The third point is caused by insect infestation. Everyone feeds this in a room with poor natural ventilation. Small bugs such as budworms and planthoppers are often found on the leaves.

This insect is very small and sticks to the leaves to digest and absorb the water and nutrients of the leaves, making the leaves curl. I can't find it, and the leaves will wither over time, so in this case, check the back side of the leaf immediately to see if there are any small insects. If the seedlings of clematis we raise are relatively small, directly put under the sun, its root system is not very strong, it can not accept too strong light, the light is too strong, the leaf transpiration is increased, the water and nutrients consumed are relatively large, the root system is relatively weak, and the absorption is not on the volatilization of his entire branches and leaves, so it is said that the seedlings are put in a place where the light is relatively weak, so that the leaves will not be curled and dry.

If there is a small number of leaves at the bottom will turn yellow and wilt, this is a normal phenomenon, which may be caused by excessive temperature, improper light, improper watering, excessive fertilization, poor ventilation, and pest and disease infestation.

It is not always caused by wilt, but can also be caused by insufficient sunlight, improper watering, and malnutrition.

There may be a lot of it, it may be due to too much watering, it may be due to his environment, it may also be caused by blight, we have to go to the sun more, to check his leaves.

1. In order to make clematis grow better, it is necessary to fertilize in time, but the amount of fertilization must be controlled, not too much too often, if the fertilizer concentration is too high, it will cause the leaves to turn yellow.

2. Clematis needs sufficient light, but it should be properly shaded in summer, because the summer sun is relatively strong, if it is irradiated for a long time, it will easily cause the leaves to wither and yellow.

3. Too much water or lack of water can easily lead to yellowing of leaves.

4. If it is placed in a closed and cool breeding environment for a long time, it is easy to have yellow leaves and even die.

Solution: 1. Appropriate amount of fertilization, which can be increased appropriately during the growth period, and normal fertilization is required in normal times.

2. It needs about 6 hours of light a day, and can not be exposed to strong light for a long time in summer, sufficient sunlight is conducive to its growth, and strong sunlight will affect its growth.

3. When you find that the soil is dry, you should water more properly, if the soil has stagnant water, do not water it again, you can also spray some water frequently to keep it moist.

4. It can be placed in a well-ventilated position, and if it is indoors, it can also be properly opened or placed directly in the sun.

When the young leaves of clematis are dry, we must pay attention to observe whether there are pests and diseases, and if there are, we must pay attention to spraying the appropriate concentration of pesticides. It is also possible that it is due to the unadaptation of the temperature environment, you can search the literature and raise the plant according to the instructions.

Lack of water, clematis needs to absorb enough water when breeding, under normal circumstances should be watered every three to five days, if the watering interval is too long, it will cause water shortage, its leaves will wilt.

The garden soil itself is alkaline, although it is certainly not good to be so compacted, not only when watering the surface of the potting soil there are white water splashes to penetrate slowly, but also slow to dry, every time after watering to muddy for several days. , the surface is cracked, the bottom is still wet, the soil is too alkaline, and there are germs, presumably this time it suddenly withered,

1.One is that the soil is unsuitable and prefers alkaline and well-drained soil. If the soil is too acidic or too sticky, it will hinder the respiration of the root system and cause wilting.

It should be treated with soil replacement in time. 2.The second is overwatering, preferring moisture but not tolerant of waterlogging.

Water is easy to soak, causing wilting. 3.The third is to be infected with pests and diseases, no matter what kind of pests and diseases will hinder growth.

Due to the single type of fertilizer applied, the leaves of clematis will dry up, so in the later stage of cultivation, it is necessary to apply nutritionally balanced compound fertilizer to clematis to supplement nutrition. Strong sunlight can also dry out the leaves of clematis, so when the light is too strong, you need to block out the strong light in time.

Fertilization is single. The drying of clematis leaves may be related to single fertilization. When cultivating clematis, too much nitrogen and several fertilizers will make the clematis appear in a state of elongation, and the leaves will turn yellow and yellow due to potassium deficiency, so in the later stage of breeding, it is necessary to apply a nutritionally balanced compound fertilizer.

Overwatering. Clematis is suitable for growing in a humid environment, if the soil is in a dry and water-deficient state for a long time, the root system of clematis can not absorb water, which will cause the leaves to turn yellow, at this time to water enough water, soak the entire soil, so that the soil is in a slightly moist state.

Bright light exposure. In the process of growth, clematis has relatively high requirements for light, but is not resistant to strong light exposure, if placed in strong light for a long time to maintain, clematis leaves will dry up, so when the light is too strong, it is necessary to build a shade net above clematis to weaken the light.

Pest and disease infestation.

During the growth process, the leaves will also turn yellow after being attacked by diseases, so the withered leaves should be cut off with sterilized sharp scissors so as not to affect the growth and health of other leaves. After pruning, carbendazim should be sprayed on clematis leaves for sterilization and disinfection.

Most of the causes of wilt are caused by the damp air and the invasion of mold into the branches.

Therefore, in the rainy and warm spring, wilt will be more frequent. This is especially true when the weather is particularly sunny after heavy rains. In fact, the wilting point had already occurred a few days earlier, because of the rain, the branches did not lack water, and they still maintained the illusion of health.

When the sun came out, the branches were suddenly short of water, and the top shoots drooped down.

It is difficult to detect blight in advance, and it is not necessary to check every branch point by point every day;

However, taking some precautions as much as possible during the planting process, although it cannot be absolutely avoided, can still reduce the probability of some occurrences.

Although blight is common, it is generally not fatal. If only one or two branches are wilted, the treatment is to prune the wilted branches away from the blackened spots, which will have no effect on other healthy shoots. If the whole plant is wilted, after pruning it all, only the root system remains, and it is possible to grow new branches in the fall.

In fact, there is no need to discard the withered branches, if you find it in time, cut off the top shoots with flower buds, keep the semi-lignified part of the branches, and put the leaves in the water for a while, and the leaves will be very alive, which can be used for cuttings.

Try not to use organic fertilizer in winter at the root node, otherwise, the organic fertilizer that is not completely fermented is very easy to produce mold; In the early spring blight season, you can use some carbendazim, watering or spraying.

Enhance ventilation and reduce the generation of mold.

And the most important point is that everyone should try to choose a regular flower shop when buying, and before buying, you must understand your needs clearly, and buy back a pot of clematis varieties that are suitable for you.

The cause of clematis wilting may be due to the humid air, which leads to mold. Therefore, it is generally easy to wilt when it is rainy or humid and the climate is relatively warm.

However, it is difficult to detect the wilting of clematis in advance, after all, it is impossible for everyone to keep an eye on it all the time. Prevention is still possible, and it can prevent the wilting of clematis to a certain extent.

First of all, when we are breeding, we should pay attention to fertilization, and try not to apply to the root system, so as not to cause rot and mold. The second is to spray some fungicide, in early spring, it is the time when the wilting occurs for a long time, at this time you can spray clematis with carbendazim and other agents to prevent wilting. Enhancing the ventilation of the environment and keeping the air flowing can also reduce the occurrence of mold.

Another point is to choose suitable good varieties when worrying about flower seedlings. This way the plants will be healthier.

Clematis often wilts, but many times it is less deadly.

If only a few branches of clematis have wilted, it is relatively simple to deal with them, just prune the branches from the blackened point, and the rest can grow normally.

If the clematis plant is wilted severely, then it should be pruned a lot, and after cutting off all the branches, the root system will be retained, and new branches can grow again.

You don't have to throw away all the cut branches, you can choose semi-lignified branches that grow better and use them for cuttings.
