What should I do if the leaves of the pear tree wilt? The leaves of the pear tree are dry, what s go

1. Soil alkalization.

During the growth of pear trees, the leaves turn yellow and wilt, which may be caused by soil alkalization. After the soil is alkalized and agglomerate, the root system of the pear tree grows poorly, and it cannot breathe and absorb nutrients normally, which will cause the leaves of the pear tree to wilt and turn yellow. If the soil is alkalized, you can use a soil conditioner for the pear tree, which can adjust the acidity and alkalinity of the soil.

2. Insufficient light.

Pear trees love light, but seedlings and potted pear trees are not tolerant to strong light and are suitable for growing in a mild light environment. During the maintenance period, seedlings and potted pear trees are exposed to the scorching sun for a long time, which is easy to sunburn, and the leaves will turn yellow and wilt. If it is caused by too much light, it is necessary to shade the seedlings and change the growth environment of the potted pear trees to a cool and ventilated environment.

3. Overwatering.

Pear trees need water during the growth period and are not resistant to waterlogging and need the right amount of watering during the maintenance period. During growth, when overwatered, the root system of the pear tree is damaged, and the leaves turn yellow, dry out, or wilt. If it is caused by overwatering, it is necessary to loosen the soil for drainage of the pear tree, and the watering frequency needs to be adjusted later.

4. Insufficient fertilizer.

Pear trees have a higher need for fertilizer during the growing period, especially before the flowering and fruiting period. Pear trees lack nutrients during the growth period, flowers and fruits grow poorly, and the leaves will wither and the flowers will not open. If it is caused by insufficient nutrients, it is necessary to supplement fertilizer to the pear tree in time, and the fertilizer is mainly composed of Bika granule compound fertilizer containing nitrogen, phosphorus and potassium.

Is it a lack of water before, cutting off the dead leaves, it may have an effect.

Hello dear, pear scab: It is common in all pear producing areas, and the disease is especially serious in years with more rain. Pear scab disease occurs in sepals, fruits, leaves, petioles, new shoots and bud scales, and the lesion is bent at the beginning of the pale yellow round lesions, which gradually expand, and then black mold grows.

Leaf damage mostly occurs on the back of the leaf, extending the veins of the leaf, and the disease of the leaf is suppressed. Fruit damage is mostly caused when the fruit is young, and the lesions expand with the increase of the fruit, and the fruit will fall early when it is severe. Pear scab can occur throughout the growing season, with the heaviest in April and May.

Pathogen spores are mainly spread by wind and rain, and the most suitable temperature is 20 oC 23 oC.

Summary. Pear leaf scorch blight is a common abnormal physiological phenomenon in the growing season of pear trees, which is often manifested by the sudden appearance of scorched oranges on the edge or front of a large number of leaves, which further expands to more than half a leaf and causes a large number of leaf drop.

Pear leaf scorcht is a common abnormal physiological phenomenon in the growing season of pear trees, which is often manifested as the sudden appearance of a large number of leaf edges or former friends or clever ends, which further expands the bond to more than half a leaf and causes a large number of defoliation.

The main reasons for its occurrence are as follows: 1. Fertilizer damage causes high pear leaf scorch blight after spring rainfall, the leaf tip or front leaf margin of the sapling or young tree suddenly turns yellow and scorched in 2 3 days, and the boundary is obvious, and soon expands to more than half of the leaves, resulting in a large number of leaf fall. Digging up the roots corresponding to the side branches with more scorched leaves, you can see a large number of white absorbing roots turning brown, drying up and dying, and sometimes you can see the fertilizer that has not completely dissolved in the shed bridge.

This type of scorch blight is caused by fertilization.

2. Pear leaf scorch wilt caused by water imbalance summer drought, some varieties of pear trees peripheral extension branches, long branches at the front end of the leaf edge or leaf tip suddenly yellow, scorched, the boundary is obvious, the development of limbs is very fast, most or the whole leaf yellow-brown, scorched, brittle, in severe cases, the front leaves of the short and medium fruit branches also turn yellow. The causes of this type of scorch wilt are complex and complex, which are related to the sudden increase of leaf water transpiration, root weakness, hypoxic asphyxia, and water reflux caused by excessive concentration of soil solution.

3. Waterlogged pear resistant to scorchroids in summer and autumn, with more rain, the low-lying plots in the pear orchard are waterlogged for a long time, and the upper leaves of the branches of the pear tree gradually turn yellow, scorched, and fall into the leaves, and the roots under the tree absorb root rot, have a sour rot smell, and the skin holes of the side roots are enlarged and blue. This type of scorching is caused by waterlogged root rot.

There may be several reasons why the leaves of potted pear trees wilt off more than acres:

1.Underwatering or overwatering: If the leaves of a potted pear tree are wilting, the first thing to check is whether it is caused by improper watering. Too much or too little watering can cause water shortages in the roots of the pear tree, which can cause the leaves of the pear tree to shrivel and wilt.

2.Insufficient nutrients: Pear tree potted plants need sufficient nutrients to grow luxuriantly, and if they lack nutrients, the leaves will shrivel and turn yellow. It is necessary to make an appropriate amount of fertilizer to provide sufficient nutrients for the pear tree.

3.Too much or too little sunlight: Pear trees prefer a sunny environment, and if placed in a low-light environment, the leaves will shrivel. However, excessive sun exposure can also dry out the leaves and damage the roots, causing the leaves to shrunk.

4.Pests or diseases: Leaf wilting of potted pear trees can be due to being attacked by pests and diseases. Common pests include aphids, slugs, whiteflies, etc.; Common plant diseases include brown spot, anthracnose, etc.

In view of the above reasons, you can take corresponding measures according to the actual situation, such as watering management, strengthening nutrient supply, paying attention to adjusting the light environment, eliminating pests and diseases, etc. If you still have any questions, please feel free to contact me.

The leaves of the pear tree are withered, what**, how**?

If the leaves of the pear tree are withered, it is due to a variety of reasons, such as pests and diseases, lack of water, malnutrition, etc. You can take a closer look at the leaves and trunk of the pear tree to see if there are any signs of insect infestation or germ infection. If so, the corresponding pesticide can be used for spraying.

At the same time, to ensure that the pear tree has sufficient water and nutrients**, it can be changed to proper fertilization and watering. If the leaves of the pear tree have withered, the leaves and wilted branches can be cut off to promote new growth. If the situation is more severe, it is recommended that you consult a professional horticulturist or agricultural technician so that you can better solve the problem.
