What to do when persimmon trees drop fruit? Find the cause and treat it accordingly

Persimmon trees dropping fruit is a serious matter, because persimmon trees are generally quite tall, and when the persimmons fall to the ground, in many cases they are already smashed. So why do persimmon trees drop fruit? It is mainly caused by three aspects. Below, QinNong Wang takes everyone to understand the causes of these aspects and their prevention and control methods.

1. Causes related to the persimmon tree itself

Persimmon trees dropping fruit also has certain causes related to the tree itself. First, its own vegetative growth is too vigorous, resulting in scarce nutrients at the fruit site, and later the calyx cannot bear the weight of the persimmon, causing it to fall. Poor pollination at the early stage can also lead to this situation, and fruit drop can also occur when the fruit does not develop fully in the later stage. Finally, when too many persimmons grow on the same branch, after the persimmons become larger in the later stage they compete with each other for nutrients, and some that grow poorly also cause fruit drop.

Solution: For branches with vigorous vegetative growth, everyone should handle them, and in places with dense branches and leaves, some should be properly cut away so that nutrients are transported to where they are needed. During the early pollination period, everyone needs to observe more. If it is not ideal, artificial pollination is needed to ensure later development. Finally, when flowering, if the flowers on certain branches are too dense, or after fruiting the branches with more fruit grow noticeably slower than other fruit, some should be manually removed.

2. Environmental factors

Environmental factors can also easily cause persimmon trees to drop fruit. First, if water and fertilizer cannot keep up, the health of the persimmon tree will decline severely, and at this time serious fruit drop will occur, because the tree body can no longer maintain the nutrient needs of the fruit. Second, if the weather is unfavorable for a long time, with continuous exposure to strong sun or rain, the growth and development of the fruit will be seriously hindered, it cannot grow, and in the end it can only fall. If the soil where it is planted is too poor, then there is even less to say. If the persimmon tree itself is already developing poorly, is it not very normal for it to drop fruit?

Prevention and control methods: Fertilization is particular. Persimmon trees have different fertilizer needs at different time periods. In the early planting stage, various trace elements are needed, so more farmyard manure should be applied. In the later stage, to ensure the vitality of the fruit, chemical fertilizers should be the main choice. In cases of heavy rainfall, drainage measures should be done well, especially at the roots. In severe cases, some rain-blocking items can be set up at the roots. In hot weather, the water supply must be ensured. If it is hot for a long time, clean water can be sprayed over the entire persimmon tree to achieve the purpose of cooling. The fertility of the soil in the early stage must be ensured well. It is best to carry out composting for a period of time before planting.

3. Pests and diseases

This is one of the more serious aspects of persimmon trees dropping fruit. For example, the most common persimmon calyx borer is one of them. When found, the number is usually relatively large, and it causes serious damage to the calyx of the persimmon, reducing the vitality of the calyx or even causing it to wither. In the end, without the pulling force, the persimmon can only fall.

Prevention and control methods: The persimmon calyx borer often occurs in summer, around July, which is an important period when the larvae of the persimmon calyx borer begin to molt. If everyone finds larvae, they can be removed manually. For affected tree bodies, 50% dichlorvos emulsifiable concentrate 1000-fold solution can be sprayed for prevention and control. Generally, spraying twice with an interval of about 20 days is enough.

Persimmon trees dropping fruit is relatively normal. Persimmons that are growing normally will also fall under some external forces. So if a few drop occasionally, everyone should not be too nervous. When dropping occurs relatively frequently, attention must be paid, and it is necessary to check whether the above situations exist, so as to treat the root cause. During daily orchard inspections, everyone should try not to pass under the persimmon trees, to avoid unnecessary harm.
