Why do cherry blossoms drop their leaves early? Please advise
Cherry blossoms normally drop their leaves in September. If cherry blossoms drop their leaves early, there may be three reasons. The first is pests: the larvae of longhorn beetles can, under the bark at the base of the trunk, cause an entire branch to drop its leaves early, and if the larvae are in the main root, they cause the whole tree to drop its leaves early, so checking whether there are pests is very important. Generally speaking, a nitrogen content of 3‰ is relatively suitable; if it is not stirred evenly, the concentration at the bottom increases, which can also cause the tree to drop its leaves early. In addition, dry climate, uneven water supply, water shortage in the nursery or excessive rainwater accumulation, causing poor tree growth and blocked nutrient transport, can also lead to early leaf drop. It is worth mentioning that this summer the south had excessive rain, which easily causes soil compaction and hinders the exchange between soil gases and air. Only by strengthening the management of fertilizer and water can the tree's resistance be enhanced and normal leaf drop occur.
