How should large cherry trees be managed in summer? What should be noted? Experienced netizens are also asked to help explain.Summer is a critical period for the growth of large cherry trees, and pests and diseases are also very likely to occur. Therefore, Zhongdi Network has compiled three key points for summer management of large cherry trees. They are listed in detail below for netizens' reference.
Key point one: Pinch the tips of the cherry trees:
Because large cherry trees grow vigorously in summer, too many leaves and branches have a certain impact on the fruit set of the following year. Therefore, when 1-year-old branches grow to more than 25 cm, the tips should be pinched in time. Pinching must be carried out repeatedly to have some control over the tree's growth vigor.
Key point two: Bend the branches of the cherry trees:
Because all cherry trees that do not bear fruit or bear little fruit are caused by improper branch bending. For branch bending of large cherry trees, the angle between the main branch and the trunk should be controlled at 90°; 70° or 80° both have an impact on 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 tomatoes, leaf thinning should be reasonable, and it is recommended to use hemp rope or other rope.
Key point three: Pest and disease control for cherry trees:
Because increased rainfall in summer easily induces various diseases in cherry trees, during this time leaf pests and diseases on large cherry trees occur relatively severely. The main leaf diseases are brown spot disease and black spot disease. The main prevention method is: promptly spray carbendazim or mancozeb before 10 a.m. or after 4 p.m. on sunny days for control; the main pests are scarab beetles, peach leaf blotch miners and various slug moths. The control method is: spray 5% cypermethrin 2000-fold solution, which has a good control effect.
