Hawthorn trees, as one of China's traditional fruit trees, are loved by people for their unique fruit taste and medicinal value. In recent years, many hawthorn trees have shown symptoms of leaf shedding, causing confusion among many fruit farmers. This article will unveil the reasons why hawthorn trees lack leaves and provide corresponding maintenance measures to help you restore the vitality of hawthorn trees.
Reasons for Hawthorn Trees Lacking Leaves1. Disease Infection
One of the reasons for the leaf shedding of hawthorn trees is disease infection. Common diseases include powdery mildew and spot diseases, which can cause leaves to turn yellow and fall off. The occurrence of these diseases is related to factors such as climate, soil, and management.
2. Pest Infestation
Pests are also an important cause of leaf shedding in hawthorn trees. Common pests include red spiders and aphids, which extract nutrients from the leaves, causing them to wither and fall off.
3. Malnutrition
Poor soil and improper fertilization can lead to malnutrition in hawthorn trees, which in turn affects leaf growth. A deficiency in elements like nitrogen, phosphorus, and potassium can cause leaves to turn yellow and fall off.
4. Climatic Factors
Abnormal climate conditions, such as drought, high temperatures, and low temperatures, can also cause hawthorn trees to shed leaves. Especially in spring and autumn, when climatic changes are significant, leaf shedding is more likely to occur.
Maintenance Measures for Leafless Hawthorn Trees1. Prevent and Treat Diseases
Regularly inspect hawthorn trees and treat diseases promptly. You can use pesticides such as Bordeaux mixture and carbendazim for control. Strengthen orchard management, maintain ventilation and sunlight in the orchard, and reduce the occurrence of diseases.
2. Prevent and Treat Pests
For pest control, pesticides such as pymetrozine and abamectin can be used. Strengthen orchard management, clear away weeds, and reduce the breeding of pests.
3. Improve Soil
Based on soil test results, fertilize appropriately to supplement nitrogen, phosphorus, potassium, and other elements in the soil. Pay attention to soil drainage and aeration to create a favorable growth environment for hawthorn trees.
4. Watering in Time
Water appropriately based on the climate and soil conditions to keep the soil moist. Avoid excessive or insufficient watering to prevent affecting the growth of hawthorn trees.
5. Pruning Branches
Prune the branches of hawthorn trees in time, removing diseased and weak branches, as well as crossed branches. This improves ventilation and sunlight in the orchard, which is beneficial for the growth of hawthorn trees.
Hawthorn trees lacking leaves is a complex issue involving multiple reasons. Understanding these reasons and taking corresponding maintenance measures can help restore the vitality of hawthorn trees. It is hoped that this article can provide some help to fruit farmers and remind everyone to focus on scientific management during the planting process, creating a favorable growth environment for hawthorn trees.
