I planted a cherry tree, why are the old leaves yellow and wilting, what s the matter?

If the leaves of the cherry tree are wilted, if it is caused by pests and diseases, the leaves of the diseased branches and insects should be cut off and burned, and carbendazim and other agents can be sprayed for treatment. If it is caused by insufficient water or fertilizer, it is necessary to replenish water and fertilizer to the cherry tree in time. If it is caused by low temperatures, the frozen branches of the cherry tree should be cut off to avoid the consumption of nutrients.

There are many reasons why cherry leaves turn yellow, and we can look at them from the following aspects.

1. Caused by lack of water.

When the climate is severely drought and water shortage, fruit trees will dry up and yellowish due to lack of water.

2. Caused by fertilizer and drug damage.

Too much fertilization or fertilization close to the root system, or the concentration of pesticides sprayed is too high, and too much dosage will cause the leaves to turn yellow, and the intuitive manifestation is that the leaf tips and leaf edges are yellow, and then rust color.

3. Caused by pests and diseases.

Exposure to fungal and viral erosion will cause different degrees of yellowing. The main manifestations are that the leaves are dark and light yellow, and the edges are not clear; with striped spots, yellowish and green along the veins, with broad bands or fine reticulations; It is a bright yellow patch of varying sizes with well-defined edges.

Fruit trees that suffer from insect infestations can also have yellow leaves.

4. Caused by lack of elements.

Cherry trees need a variety of trace elements to support their growth. The absence of a certain element will have a different reaction. The old leaves lacking nitrogen lost their green and yellowed, and finally fell off; The upper part of the iron-deficient treetop has only the veins of the new leaves that are green, and the other parts are yellow or yellow-green; When zinc is deficient, the leaf veins are normal and the mesophyll is yellow.

Second, how to prevent and control.

1. Prevention and control of water shortage: in dry weather, it is necessary to do a good job in water management, timely watering, and keep the soil applied, but one watering should not be too much, and the soil can be properly loosened after irrigation to maintain soil permeability, and drainage should be paid attention to in the rainy season, so as not to accumulate water and cause diseases.

2. Prevention and control of fertilizer and pesticide damage: when fertilizer damage and pesticide damage occur, irrigation can be carried out in time to alleviate the concentration of pesticides and fertilizers, reduce damage, or spray growth regulators to alleviate the damage, and the effect is better.

3. Pest control: pest and disease hazards should be prevented and controlled in time, and 25% tebuconazole 4000 times + Kemykang 1000 times + Aizengmei 30 kg of water 5 ml + Trim amino acid foliar fertilizer 500 can be sprayed on the whole tree, and sprayed again after ten days, and peach Xiaoling is added to kill insects.

4. Prevention and control of element deficiency: for the symptoms of yellow leaves caused by deficiency, the best prevention and control measure is to supplement the corresponding elements to make them recover.

According to the situation, it is necessary to determine what causes the yellowing and wilting of the leaves, so as to grow good quality cherries.

If the leaves of the cherry tree suddenly wilt, if it is caused by low temperature frost, you can remove the leaves, residual flowers, and fruits that have been damaged by the frost, and cover the cherry tree with straw to keep warm. If it is caused by a lack of fertilizer, it should be supplemented with fertilizer to supplement nutrition, and trace elements should also be applied. If it is caused by pests and diseases, the cause can be found out and targeted spraying.

If it is caused by insufficient watering, you can water it in time to ensure water supply.

1. Pruning and insulation.

Cause: The leaves on the cherry tree suddenly wilted, possibly caused by a sudden drop in temperature, causing the cherry tree to suffer from frost. When the branches and leaves of a cherry tree are damaged by frost, the leaves wilt, rot and turn black.

Solution: If this is the reason, you can remove the frost-damaged branches, leaves, residual flowers, and fruits to reduce nutrient consumption, and cover the cherry tree with straw next to it to keep warm, which is conducive to the recovery of the cherry tree.

2. Increase fertilizer.

Reason: Cherry trees need nutrients to grow, and reasonable fertilization can ensure growth, if there is a lack of fertilizer in the growth, it may lead to nutrient deficiency and cause leaves to wilt.

Solution: Determine the lack of nutrients in the cherry tree, apply fertilizer to supplement the nutrients such as water-soluble fertilizer in fertile leaves, and apply trace elements to ensure good nutrition, and wait for the cherry tree to absorb enough nutrients to alleviate the wilting situation.

3. Prevention and control of pests and diseases.

Causes: Improper maintenance may cause cherry trees to be infected with pests and diseases, and it can also cause leaves to wilt.

Solution: Determine what pests and diseases the cherry tree is infected with, and then spray the drug symptomatically.

4. Replenish water.

Causes: Long-term failure to water can lead to soil drought, which can cause the leaves to wilt.

Solution: After finding that the soil is short of water, the cherry tree should be watered in time to promote the roots to absorb enough water.

If this happens, it is likely that the damage is too heavy, and there are too many branches on the tree, and the ** of water and nutrients is also deformed.

High temperature and water shortage is one thing, organic matter is reduced, and the possibility of nitrogen deficiency is greater.

Yellowing and wilting leaves are generally considered to be a problem with the rhizome.

Summary. The following measures are mainly taken to prevent and control it.

Disease control: for diseased plants, open the roots in spring, cut off the roots and irrigate the roots; Before germination in spring, spray stone sulfur mixture to prevent and control branch dry rot, for the diseased, scrape off the lesions in time For the prevention and control of gelatinous disease, the trunk can be brushed with 10% 20% solution of fungus poison in early spring in early March, if there is a flow gum disease in the growing season, it can be brushed with fruit rot or fungus poison clear liquid at any time, and the trunk is painted white in autumn.

In addition, the wound should be minimized when pruning. The use of water-soluble fertilizers at the peak of the incidence can prevent or reduce the occurrence of such phenomena.

Why did the newly planted cherry trees grow leaves and wither?

Hello, I'm your counselor and I'm sorting out the answers for you, please wait.

Cherry trees have dead branches, indicating that they are infected with pests and diseases. The main diseases that harm cherry branches are cherry root cancer, branch stem rot, and gum disease. The insect pests are mainly red-necked beetle, golden-edged gilding, mulberry scale scale insect and so on. All of these pests and diseases can lead to dry branches.

Summary. Hello, half of the leaves of the cherry tree are yellow, if it is caused by long-term lack of water or water accumulation in the roots, it should be watered regularly during the growing period to keep the soil moist, if it is too much watering, you can stop watering and set up drainage ditches to promote drainage. If it is caused by the lack of a certain nutrient element, it is necessary to fertilize reasonably to meet the nutritional needs.

If it is caused by infection with pests and diseases, after the occurrence of pests and diseases, the diseased branches and leaves should be pruned, the types of pests and diseases should be determined, and the corresponding spraying should be carried out**.

Big cherries are also called cherries, cherry beads, Yingqing fruit, when the cherries are ripe, the fruit color is bright red, delicate and clear, and the taste is sweet and sweet. The large cherry hall is rich in vitamins A, B, C and iron. The big cherry has the effects of regulating and replenishing qi, nourishing blood and beauty, and anti-aging, and is widely loved by everyone.

When the leaves of the cherry tree are yellow and dry, it is necessary to observe the state of the leaves, analyze them well, and deal with them in a targeted manner.

Ways to improve the yellowing and dryness of the leaves of cherry trees:

1.Without fertilizer, the leaves of the cherry tree will turn yellow and dry.

Generally, the lack of fertilizer is mainly manifested in the color of young leaves, which become pale green or yellow, while the old leaves will gradually turn from green to yellow.

Solution: The state of the cherry tree should be observed in time, and when the soil is compacted, the soil should be loosened or replaced in time. When fertilizing, you can properly water some alum water to supplement iron.

2.The lack of water causes the leaves of the cherry tree to turn yellow and dry up.

Lack of water and yellowing of leaves is not the same as yellowing due to excessive watering, yellowing due to lack of water means that the tips or edges of the leaves are dry, and the old leaves are yellow and fall off from the bottom up, but the growth of new leaves is relatively normal.

Solution: Watering in time, replenishing water, watering should be watered thoroughly at one time.

3.The lack of light causes the leaves of the cherry tree to turn yellow and dry up.

Cherry trees are in a shady environment for a long time, and the leaves cannot absorb light and form chlorophyll, resulting in yellow and dry leaves.

Solution: Replenish sunlight in time, because there is a lack of light in the early stage, so the cherry tree should be placed in a place of astigmatism first, and gradually increase the light to avoid burning the leaves.

4.Overwatering causes the leaves of the cherry tree to turn yellow and dry up.

Excessive watering is mainly manifested in the young leaves are dark yellow and dull, the old leaves have not changed, and the branches are small and yellow-green.

Solution: Loosen the soil to speed up the flow of water. Place the cherry tree in a well-ventilated place.

5.Yellow leaf deficiency causes the leaves to turn yellow and dry.

The lack of oxygen in cherries causes the old leaves to turn yellow until the old leaves fall off. Iron deficiency in cherries can also cause yellowing of leaves, mainly manifested in the fact that the veins of the new leaves in the upper part of the shoots are green, and the rest of the leaves are yellow-green or yellowish-white, the leaves are small and thin, and the edges of the leaves are scorched and withered, and a lot of them fall off.

Solution: This symptom is due to a lack of nutrients, and the missing elements should be supplemented accordingly to allow it to recover. Foliar fertilizer supplementation can be used to supplement elements in a targeted manner.

6.Pests and diseases make the leaves yellow and dry.

When cherry trees are damaged by pests and diseases, the leaves will be dull yellow with fuzzy edges.

Solution: Strengthen the defense of pests and diseases, timely pests and diseases, targeted medication, and strengthen the management of fertilizers and water.

Lack of water, fertilizer, pests, lack of elements, and other factors will cause the yellowing of cherry leaves, and different solutions should be found according to different reasons.

The maintenance method of cherry trees eliminates the disadvantages of liquids.

1. Pay attention to the time period after the pruning of large cherry saplings.

Large cherry seedlings are not suitable for a large number of pruning in a dormant state, because there is a wound flow, and should be pruned after the fruit is harvested in summer. During this time, the tree is very vigorous, and the wound heals quickly after pruning, and there is no glue flow.

2. It is necessary to pay attention to the frost protection of large cherry seedlings during the flowering period.

Flowering frost is a relatively common natural disaster for large cherry saplings to bury erections. Choose a good frost resistant option. Smoke before frost reduces the hazard.

3. Pay attention to the vigorous growth of fruit tree seedlings.

Considering the strength of large cherry seedlings, especially in summer, it is difficult to enter the fruiting period early. Only by maintaining a medium-strong fruit tree seedling can it have a high yield and stable yield. The rapid growth period of new shoots can last 2 to 3 times of topping, the branch corners are opened, and the branches are pulled before and after the autumn equinox.

4. Pay attention to timely fertilization.

Cherry trees can be sprayed with fertile leaf foliar fertilizer before the flowering stage, which can promote flower bud differentiation and lay the foundation for later yield increase.

Have you used any fertilizer or medicine, or have you used too much herbicide, or it is bacterial wilt, look at the root situation.

Causes and control methods of yellow leaves of cherry-peach trees

1. Yellow leaf type buried wax deficiency.

Nitrogen deficiency in cherry-peach causes the old leaves to turn yellow, which is manifested as the old leaves turn yellow, and finally the old leaves fall off. Iron deficiency in cherry-peach also leads to yellow leaves, which is manifested by the fact that only the veins of the new leaves in the upper part of the shoots are green, and the veins are green. The rest is yellow-green or yellowish-white, the leaves are small and thin, the leaf margins are charred and withered, and a large amount of them fall off; Zinc deficiency in plants also leads to yellow mesophyll and sequential development in the veins.

Prevention and control methods: For the symptoms of yellow leaves caused by nutritional deficiency, the best prevention and control measures are to supplement the corresponding elements to make them recover. For yellow leaves caused by various defects, foliar fertilizers can be used to supplement targeted supplements.

2. Yellow leaves with pests and diseases.

When the plant is destroyed by a viral disease, the leaves are dull yellow, with unclear edges, or bright yellow, with stripes of varying sizes, the salt veins turn yellow to green, the bands or fine reticulations widen, and the vein margins turn yellow. The yellow leaves caused by root rot are small and yellow. Within a few days, the leaves will turn yellow and charred.

Sakura-peach seedlings suffer from one or more pests, and yellow leaves will also appear.

Prevention and control methods: pay attention to the prevention and control of pests and diseases, timely control of pests and diseases, strengthen the management of fertilizer and water, and make them recover.

3. Drought and water shortage.

When the climate is severely drought and water shortage, fruit trees dry up and turn yellow due to lack of water.

Prevention and control methods: In dry weather, water management should be done well, timely watering and soil application, but not too much water at a time. After irrigation, the soil should be properly loosened to maintain soil permeability, and the liquid traces should be paid attention to drainage in the rainy season to avoid water rooting and disease.

4. Fertilizer and drug injuries.

The destruction of chemical fertilizers and pesticides often results in the yellow leaves of the cherry-peach trees. When fertilizing too much or near the root system, or when the pesticide concentration is high and the pesticide dosage is too large. When fertilizers and pesticides are destroyed, the tips and edges of the leaves are mostly yellow, and then rusty.

Control method: When fertilizer damage and pesticide damage occur, timely irrigation can reduce the concentration of pesticides and fertilizers, reduce the damage, or spray growth regulators to alleviate the effect.

5. Yellow leaves with root rot.

Yellow leaves caused by root rot, large cherry tree-peach seedlings with rotten roots, small and yellow leaves, all the leaves turn yellow and scorched within a few days.

6. Arid yellow leaves.

Fruit tree drought, due to the lack of water in the fruit tree, resulting in the leaves of the fruit tree due to lack of water and yellowing.

7. Early deciduous yellow leaves.

Early defoliation disease of fruit trees can also cause yellow leaves of fruit trees, which are mainly brown spots, with green lines around the lesions and gradually turning yellow outward.

8. Bacterial perforated brown spot disease yellow leaves.

Symptoms are irregular macula or brown ban, and some leaves are perforated.

9. Magnesium deficiency yellow leaves.

The symptoms are green veins and yellowish mesophyll, which are transverse and one by one on the leaf surface.

The above is the analysis of the reasons for the yellow leaves of the large cherry tree-peach sapling, according to the above reasons. Targeted treatment can be carried out to improve the survival rate of cherry-peach seedlings and achieve high yields.

In general, there are many reasons for the yellowing of cherry and peach leaves, and the main problem is the problem of fertilizer. Increase the application of phosphorus and potassium fertilizers and trace element manganese. It can also improve the acidity of the soil, which is conducive to the absorption of water and fertilizer by the roots.
