Summer is a critical period for the growth of sweet cherry trees, and pests and diseases are also very likely to occur, so fruit growers should pay attention to the summer management of sweet cherry trees. Doing the following points well will allow sweet cherry trees to smoothly pass through this growing season in summer.
Pinching In summer, sweet cherry trees grow vigorously, and excessive leaves and branches have a certain impact on the fruiting of the following year. Therefore, when 1-year-old branches grow to more than 25 cm, they should be pinched in time. Pinching must be carried out repeatedly to achieve some control over the tree's growth vigor.
Branch bending Summer is also a key season for bending branches of sweet cherry trees. Any large tree that does not bear fruit or bears little fruit is caused by inadequate branch bending. When bending branches of sweet cherry trees, the angle between the main branches and the trunk should be controlled at 90°; 70° or 80° both affect fruiting. Branch bending starts in June and continues until the end of August. In addition, plastic rope should not be used for branch bending; for summer cherry tomato leaf thinning, it should be done reasonably, and it is recommended to use hemp rope or other ropes.
Disease control Summer is also a period when pests and diseases occur in large numbers on sweet cherry trees. Especially with the recent increase in rainfall, leaf pests and diseases on sweet cherry trees have become relatively serious. The main leaf diseases are brown spot disease and black spot disease. The main method of prevention is: on sunny days before 10 a.m. or after 4 p.m., promptly spray carbendazim or mancozeb for control.
