Why do cherry blossoms crack their bark?

Why do cherry blossoms crack their bark? Please introduce examples of cherry blossoms with sufficient fertilizer or water supply, where the bark of cherry blossoms is cracking due to excessive growth. In this regard, the application of urea in the nursery in spring may play a relatively obvious role in promoting the growth of the plant, making its xylem grow faster, but the outer phloem failed to keep up, resulting in bark cracking. However, generally speaking, this phenomenon will not have any effect on the growth of cherry blossoms. Under normal conditions of fertilizer and water, its callus will form spontaneously within two or three years, making the bark back to normal. It's just the cracked bark that affects the landscape. But it should be noted that without the protection of bark, the crack is easy to be invaded by diseases and insect pests and needs some protection to prevent it. The use of topiramate, chlorothalonil and other agents, according to the preventive dose of regular administration, can play a very good effect. In the absence of special requirements, there is no need for other physical protection. Click for more cherry blossom planting techniques click to get more flower planting techniques
