What causes curly cherry leaves?

Curling cherry leaves may be due to insufficient moisture or nutrients, or it is possible that the plant is suffering from pests and diseases.

If the plant does not have enough water or nutrients, it is necessary to immediately fill the plant with water and nutrients, so that the plant can grow and develop normally. If the plant has pests and diseases, the leaves should be cut off and damaged immediately, and the relevant chemical drugs should be used for treatment.

Cherry leaves are curled for the sake of it.

If the leaves of a large cherry are curled during the summer season, it may be due to the lack of water on the plant. During the summer period, the temperature is high, the gas water surface evaporates greatly, and the plants are in a dry state for a long time, and the water is not enough, the leaves will slowly curl and turn yellow, and they will wither and fall off in the middle and late stages. If the plant does not have enough water, it is necessary to fill the plant with water immediately, and adjust the amount of watering in the middle and late stages.

What's going on with the curling of cherry leaves.

The curling leaves of large cherries may also be caused by pests and diseases, and the common diseases of cherry trees are budworms, longhorn beetles and scale insects. Pests attach themselves to the opposite side of the young leaves of the plant, digest and absorb the nutrients and water of the leaves, give birth to many parasites and spread viruses, which will make the leaves wrinkle and curl. If the plant has pests and diseases, it is necessary to use organic chemicals to carry out insect control.

Cherry trees lack calcium and potassium fertilizers, and the leaves of the plant will curl and turn yellow, and calcium and potassium fertilizers are the main trace elements for the growth and development of the plant. The plant lacks nutrients, and the leaves will roll slightly in the early stage, and the leaves will become lighter in tone, and in the middle and late stages, they will be completely curled and the leaves will turn yellow. If the plant is deficient in nutrients, it is necessary to fertilize the plant immediately and supplement the plant with vitamins for its growth and development.

Cherry trees in the growth period, must also have abundant light, in the case of sufficient light, the plant can carry out plant photosynthesis, accumulate nutrients, beneficial to the growth and development of plant stems and leaves, but in the summer, must do a good job of shading. If there is not enough light, the leaves will wither and turn yellow, and if the light is too strong, the plants will be burned by the scorching sun.

The cherry trees were not fertilized at the time of planting, so the leaves of the cherry trees curled.

It may be a lack of water, no regular watering, or the temperature is too high, or it may be caused by pests and diseases, or it may be a lack of nutrients in the soil.

This is because the fertilization is not enough, the water is too little, and the light is too strong, so the leaves are curled, we should go to water more, reduce the light time, proper shading, and then go to fertilization, and that's it.

It is caused by too much watering during watering, or it may be caused by the inappropriate fertilizer selected during the planting process and prolonged exposure to sunlight.

Cherry leaf curling virus is a genus of nematode-borne polyhedral viruses. The viral plasmid is equisymmetric, about 30 nm in diameter, and occurs in Europe and North America. The virus is easily transmitted by sap and has a wide range of hosts.

In several host plants, the virus is transmitted by seeds and pollen, and if pesticides are available, remove the insects, but be safe. Cherry trees, about 4 cm in diameter, more than two meters high, a few days after transplanting, the leaves are curled, spraying dichlorvos is useless Dichlorvos is still harmful to plants You should buy methamidophos in a pesticide store with water 20L water 15ml of medicine Spray.

In order to avoid this situation, we must choose some sterilized seedlings when planting, which must be particularly robust and have very developed roots. Before the tree sprouts, you can apply a circle of epoxy resin to the trunk, and the leaves of the cherry tree are rolled up like insects, which are infested by aphids. Aphids will collect on the back of the leaf and suck up the sap on the back of the leaf, causing the leaf to curl.

In the early days, it can be effectively controlled by mixing chili juice and water in a ratio of 1 to 1 and spraying it on the tree.

Foliar fertilizer can be sprayed: tebuconazole 25% 4000 times + Kecon 1000 times (can also be used for 800 times of zeb) + Aizengmei (imported from Japan) 30 kg of water 5 ml, + amino acid foliar fertilizer 500, spray the whole tree, and spray again after ten days to add peach Xiaoling. 1. Increase the application of organic fertilizer, combined with the deep application of 1% ferrous sulfate solution and animal manure mixed fertilizer.

2. Foliar spraying of ferrous sulfate solution in the early stage of fruit tree germination.

When choosing a location, you can choose according to its preferences, and it should be noted that the surrounding temperature should be kept around 10 to 12 degrees above zero, which is more conducive to its growth, and if the temperature is too low, it is easy to freeze them to death. Strengthen orchard management, especially the comprehensive management of orchards with severe disease. During the spring drought, it is necessary to irrigate water and pressure alkali, dig drainage ditches, plant green manure crops between rows or increase farm fertilizer, improve the physical and chemical properties of the soil, increase soil organic matter, and release fixed iron.

This situation must be caused by its lack of water, so it should be watered more at ordinary times, so that it will be relieved a lot.

Water more, you can also buy some pesticides to spray on the leaves of cherries, that is, you can relieve the curling of leaves, you can also water and fertilize frequently, but also add some potassium, spray directly on the cherry trees, but also supplement rich calcium, can be solved.

Watering more or proper shading, timely spraying of corresponding pesticides, timely fertilization, and supplementation of calcium, potassium and molybdenum can effectively improve the curling of cherry leaves.

The first is that you need to water more, because it can also be caused by a lack of water. The second is to spray more pesticides, sometimes because some insect pests will also cause the leaves to curl, and finally you can also add some calcium to the cherry tree, add some calcium lactate or Motrin high-efficiency calcium, you can also go.

To water the plant more or shade properly, for aphids, you can use imidacloprid 2000 times liquid or pyrethroid pesticides to spray control, but also should be scientifically fertilized, you can also use calcium lactate, calcium preparation ga calcium treasure, Motrin high-efficiency calcium and so on for prevention and control.

You can properly water the cherry tree more, and also pay attention to the shade, so that you can get a certain relief, cherry leaf curl may also be caused by aphids, at this time you can also spray some pesticides appropriately, nutrient deficiency will also cause infusion minus, so you should be fertilized in an appropriate amount to supplement nutrition to the cherry tree, and you can also spray some insect repellent drugs.

The solution is to water regularly, to control pests and diseases regularly, and to prune the leaves. It is also necessary to remove the surrounding weeds in time. You should also put more nutrients in the soil.

The solution is to water more and fertilize properly, because this situation is caused by water shortage.

The situation of cherry trees rolling leaves may be caused by the lack of water in the hot summer, so it is necessary to properly shade and water the cherry trees in time to replenish the water. It may also be caused by insufficient fertilization and lack of nutrients, so it is necessary to fertilize in time and supplement nutrients accordingly to ensure that the nutrients of the plants are balanced. It may also be caused by aphid infestation, timely spraying**, can be sprayed with 10% imidacloprid 2000 times liquid or pyrethroid pesticides.

1. Lack of water in the heat.

Reason: Cherry trees need enough water to grow, and if they are in the hot summer months and not watered in time, cherry trees may cause a lack of water and cause leaf curling.

Solution: Give the cherry tree proper shade, avoid direct exposure to the scorching sun, water the cherry tree in time, replenish the water, so that the roots can absorb the water, you can alleviate this problem.

Second, lack of nutrients.

Reason: In the maintenance, if the fertilization is insufficient, the lack of certain nutrients in the tree will also cause leaf curling, such as the lack of calcium, which will cause the leaves to scorch and appear brownish-yellow, the lack of potassium will cause the leaf edges to scorch, bend and curl the leaves, and the lack of molybdenum will cause the leaf edge to curl upwards into a cup.

Solution: Determine what nutrients are missing according to the symptoms, apply water-soluble fertilizer to the fertile leaves in time, and supplement the nutrients accordingly to ensure that the plant nutrition is balanced.

3. Aphid hazards.

Reason: Cherry trees roll leaves, or aphids are doing tricks, if not properly maintained, cherry trees may be attacked by aphids, dense aphids will gather behind the leaves, suck the juice of the leaves, causing the leaves to curl and shrink.

Solution: In addition to strengthening prevention, it is also necessary to spray in time**, which can be sprayed with 10% imidacloprid 2000 times liquid or pyrethroid pesticides.

First of all, it is necessary to understand the reason for cherry tree leaf rolling, the first common reason is caused by lack of water, cherry trees have high requirements for water in the process of growth, so cherry tree leaf rolling generally occurs in summer. At this time, the weather is very hot, and the evaporation of water is relatively high, so you must water the cherry trees in time. As long as the water is sufficient, the symptoms of leaf curling can be gradually linked, and even the occurrence of leaf curling can be directly avoided.

It is a disease, the edge of the leaf is rolled upward, the diseased branch is easy to break when shaken, and it is necessary to water it in time when the weather is hot, and during its growth, you can spray some fertilizer containing potassium.

It is a disease, and it may be infected with germs. Professionals should be found to conduct sampling and testing, prescribe the right medicine, and manage it as soon as possible**, which can minimize losses.

Hello There are several possible reasons for the curly yellowing of cherry leaves, here are some of the possible reasons:1Water shortage:

If the cherry tree is short of water, the leaves will start to curl and turn yellow. Make sure the cherry trees get enough water, especially during the dry season. 2.

Lack of fertilizer: Cherry trees need enough nutrients to stay healthy. If the soil is deficient in nutrients, cherry leaves may turn yellow and curl.

3.Pests and diseases: Cherry trees can be affected by various pests and diseases, such as aphids, mites, and aphids, among others.

These bugs suck up the sap from cherry leaves, causing the leaves to turn yellow and curl. If you find pests and diseases in your cherry tree, you can try using organic pesticides or have a professional gardener deal with them. 4.

Environmental factors: Cherry trees can be affected by environmental factors such as temperature changes, excessive sun exposure, etc. These factors can cause the cherry leaves to turn yellow and curl.

To sum up, there may be many causes of curly and yellowing of cherry leaves, and it is necessary to carefully observe the growth status of cherry trees and find out the reasons before taking corresponding measures to deal with them. Hope mine can help you. Judgment

The curling of cherry leaves may be caused by long-term water accumulation in the soil, and the hot weather in summer will evaporate the moisture of cherry leaves, so that the leaves of cherries will also curl, and may also be caused by sudden environmental changes, in addition, pests and diseases will also make the leaves of cherries curl.

Summary. Hello. Possible causes are: potassium deficiency, uneven light, improper fertilization, and infection.

Hello. Possible causes are: potassium deficiency, uneven light, improper fertilization, and infection.

You can check the specific reason for this.

The brittle and unsuppossible leaves of the cherry tree can be caused by:

Drought: If there is not enough rainfall in the area and there is not enough moisture** in the soil, the leaves of the cherry tree will dry out and the branches will become brittle and hard.

Nutrient deficiencies: If cherry trees do not receive adequate nutrient support, such as deficiencies in elements such as nitrogen, phosphorus, potassium, etc., it can lead to yellowing of the leaves and becoming brittle.

Pest and disease infestation: When a cherry tree is infested by pests or germs, it can cause the leaves to become dry, brittle, or discolored.

Heavy pruning: If over-pruning or heavy pruning, the chic can upset the balance of the tree, causing the cherry tree to grow slowly and the leaves to become dry and brittle.

In summary, ensuring the suitable growth environment and providing sufficient nutrients for cherry trees, while strengthening plant protection, can effectively prevent the leaves of cherry trees from becoming dry and brittle.

The causes of leaf curling in peach trees can be leaf shrinking disease, peach aphids, leaf curling moths, too much light, and soil discomfort.

1. Leaf shrinkage disease.

Peach tree leaf shrinkage disease mainly affects leaves, and in severe cases, it also affects flowers, young branches and young fruits. After the young leaves, they can be damaged, the leaves are curled, the color turns red, and as the leaves grow, they thicken partially or completely, and curl towards the back of the leaves. When wet, a layer of gray-white mold is produced on the surface of the leaves, and then the diseased leaves turn brown, scorched and fall off.

Diseased shoots often grow in clusters, and often prune and die in severe cases. The damage of young fruits is deformed, and the fruit surface often shows cracks and scars, and most of them fall off.

2. Peach aphid.

The harmful symptom of peach aphid is that the damaged leaves of peach trees gradually thicken from the edge to the back and curl longitudinally, and the infested part becomes hypertrophied and resembles an insect gall. It not only affects the formation of flower buds, but also weakens the tree. The honeydew excreted by aphids pollutes the leaves and branches, retards the physiological function of peach trees, often causes bituminous coal disease, accelerates early defoliation, and affects growth.

To prevent peach tumor aphid, you can use yellow plate trapping, imidacloprid when the flower dew is red, etc., if leaf curling has occurred, you should choose a strong systemic drug such as flufeniliprole, and with a dialysis adjuvant.

3. Leaf curling moth.

The peach leaf curling moth not only reduces the number of leaves, but also accelerates the growth of secondary and tertiary branches due to the destruction of new shoots, which seriously affects the robust growth of the main branches. It can cause the leaves of the peach tree to curl up in spring, and the insect eats more flower buds in the early stage, and begins to transfer the damage after the new shoots spread their leaves, which can make the whole leaf curl into a clump. The first incubation period and young larvae are the best periods for medication, and cyfluthrin, emamectin acetamiprid, avi chlorobenzyl and so on can be selected for the disturbance agents.

4. The light is too strong.

It is recommended to move the peach tree to a cooler environment, and it is necessary to prune off the branches and leaves on the table in time, and also need to water appropriately, the frequency of watering can be increased according to the situation, this reason may occur in a few cases.

5. The soil is unsuitable.

If the peach tree is not adapted to the soil, the peach tree will not be able to absorb water and nutrients normally, which is also one of the reasons for the peach tree to roll leaves, at this time it is necessary to replace the acidic soil for the peach tree, and ferrous sulfate can also be used to improve the slight acidity of the soil, so that it can gradually recover its vitality.
