Since July and August, Dalian has experienced increased rainfall, which has contributed to the vigorous growth of large cherry trees. Farmers are advised to focus on summer and autumn pruning, including branch spreading, tip pinching, and removing the central shoot. These practices help promote branch lignification, improve branch hardiness, and enhance the tree's ability to withstand cold weather and survive the winter.
At the same time, the current climatic conditions—high temperatures, heavy rainfall, high humidity, and prolonged cloudy days—create a favorable environment for leaf diseases. Early defoliation and downy mildew can spread rapidly under these conditions. This serves as a reminder for farmers to carry out timely spraying and not take any chances. Delaying treatment may lead to severe leaf loss, which can negatively affect the tree’s growth and fruit production in the following year.
In addition, it is recommended that farmers monitor their orchards regularly, especially after heavy rains, to detect any signs of disease early. Proper irrigation management is also important to prevent waterlogging, which can weaken the trees and make them more susceptible to pests and diseases. By staying proactive and maintaining good orchard hygiene, farmers can ensure healthier trees and better yields in the long run.
