With the arrival of summer, many families and organizations choose to transplant trees during this season. Many people find that after transplanting trees in summer, the trees show a phenomenon of leaf drop. Why is that? And how can we prevent this situation from occurring? This article will reveal the reasons for leaf drop in trees transplanted in summer and provide corresponding transplanting techniques and caring methods.
Reasons for Leaf Drop in Trees Transplanted in Summer1. Root Damage
In summer, when transplanting trees, due to high temperatures and high soil evaporation, the water absorption capacity of the roots is weakened. During the transplanting process, the roots are easily damaged, leading to insufficient water and nutrient supply, which causes the trees to drop leaves.
2. Climatic Factors
In summer, high temperatures and intense sunlight can easily cause trees to be affected by climatic factors such as sunscald and drought after transplanting, leading to leaf damage and subsequent dropping.
3. Tree Growth Habits
Some trees have poor adaptability to transplantation, especially large trees that have been growing for many years. Their roots are deep, and the root damage during transplantation is significant, which can easily lead to leaf drop.
Techniques for Transplanting and Caring for Trees Transplanted in Summer1. Choose an Appropriate Time for Transplanting
Try to transplant during the early morning or evening when temperatures are lower and sunlight is weaker to reduce the impact of climatic factors such as sunscald and drought on the trees.
2. Prune the Roots
Before transplanting, prune the tree moderately to remove some roots to reduce the root's demand for water and nutrients and alleviate the stress after transplantation.
3. Watering to Maintain Moisture
After transplanting, water thoroughly and keep the soil moist. You can cover a layer of straw or leaves around the trunk to reduce water evaporation.
4. Fertilization Supplement
After transplanting, you can apply a moderate amount of slow-release fertilizer to supplement the nutrients needed by the trees and promote their recovery and growth.
5. Shading and Sun Protection
In the early stage after transplanting, provide appropriate shading to reduce the impact of sunscald on the trees. Pay attention to the growth condition of the trees and adjust the shading measures accordingly.
6. Observe Tree Growth
After transplanting, closely monitor the growth of the trees. If any diseases or pests are found, deal with them promptly.
Leaf drop in trees transplanted in summer is a common phenomenon, but by mastering the correct transplanting techniques and caring methods, this phenomenon can be effectively reduced. It is hoped that this article can provide useful references for your tree transplantation.
