What to Do When Persimmon Trees Drop Fruit? A Detailed Guide to the Latest Solutions
Persimmon trees dropping fruit is a serious matter, because persimmon trees are generally quite tall, and by the time 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 Web takes everyone to understand the causes of these aspects and their 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 in the later stage the calyx area cannot bear the weight of the persimmon, causing it to drop. Poor pollination in the early stage can also lead to this situation, and in the later stage, when the fruit does not develop fully, it will also drop. 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 will also cause fruit drop.
Solution: For branches with vigorous vegetative growth, everyone should deal with them, and appropriately cut away some places with dense branches and leaves, so that nutrients are transported to where they are needed. During early pollination, everyone needs to observe more. If the situation 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 must be manually removed.
2. Environmental Factors
Environmental factors can also very 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 the sun or rainy weather, the growth and development of the fruit will be seriously hindered, it cannot grow, and in the end it can only drop. If the soil where it is planted is too poor, then there is even less to say; the persimmon tree itself is already developing poorly, so is it not normal for it to drop fruit?
Control methods: Fertilization requires attention to what is appropriate. The fertilizer needs of persimmon trees differ 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. When encountering 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 it down. The fertility of the soil in the early stage must be ensured well, and it is best to carry out composting for a period of time before planting.
3. Pests and Diseases
This is a relatively serious aspect of persimmon trees dropping fruit. For example, the most common persimmon fruit borer is one of them. When discovered, the quantity is generally quite 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 drop.
Control methods: The persimmon fruit borer often occurs in summer, around July, and this is an important time period when the larvae of the persimmon fruit borer begin to transform. If everyone finds larvae, they can remove them manually. For affected tree bodies, 50% dichlorvos emulsifiable concentrate 1000-fold solution can be sprayed for control. Generally spray twice, with an interval of about 20 days.
Persimmon trees dropping fruit is relatively normal, and persimmons growing normally will also drop 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 prescribe the right remedy. During daily orchard inspections, everyone should try not to pass under the persimmon trees, to avoid causing unnecessary harm.
