What causes jujube fruit drop

Jujube trees do experience natural fruit drop. If only a small amount drops, this is normal behavior, but if the quantity is large, then it indicates a problem. If there is a problem, what factors are mainly responsible? Let's take a look below at several reasons that cause jujube fruit drop.

1. Insufficient fertilizer

This situation mainly occurs during the flower-to-fruit transition period. At this time, the flowers begin to transform into fruit, but the connection point with the branch is relatively fragile; after all, the weight of the fruit and the flower are not on the same level. At this stage, the jujube tree's demand for fertilizer is relatively high, and nutrients are supplied to the flowers and fruits first, so the connection point receives very few nutrients. When fertilizer is insufficient, the connection point cannot bear the weight of the fruit, so fruit drops in batches as a matter of course.

2. Environmental factors

The environment also has a considerable impact on jujube fruit drop. If there is more rainy weather during the jujube tree's growing period that year, fruit drop will occur relatively frequently, because the tree body does not have sufficient light and cannot support too many fruits. Second, high temperatures and dry soil can also lead to this situation, because at this time the jujube tree is severely short of water, its own nutrient transport system is very slow, and fruit drop naturally occurs. These are mainly caused by environmental factors leading to a water imbalance within the jujube tree. Proper water control can alleviate this problem to a certain extent.

3. Excessive vegetative growth of the tree

Some growers should encounter this situation: the jujube tree grows vigorously and is full of vitality, but more and more jujubes drop, and this is caused by excessive vegetative growth of the jujube tree. In such a jujube tree, the branches and leaves themselves grow quickly and the branches are dense, and the newly grown shoots and the fruit begin to compete for nutrients. However, because the newly grown shoots have a stronger ability to seize nutrients, in the end the jujubes that can obtain these nutrients on the entire branch become fewer and fewer, and finally the fruit suffers from insufficient nutrients and fruit drop occurs. At this time, it is recommended that growers prune the fruit tree to a certain extent to suppress this problem.

4. Disease

Disease is also a major key cause of fruit drop, and many pests and diseases can lead to it. Jujube berry disease, fruit shrinkage disease, jujube fruit rust disease, and so on can all cause relatively serious fruit drop. These diseases occur because the fruit is eroded by pathogens, which then causes the vitality of the entire fruit to decline, and finally the connection point also gradually dries and rots, resulting in large-scale fruit drop. Fruit drop caused by disease can generally be analyzed from the condition of the fruit tree's leaves and the condition of freshly dropped fruit, and after further judgment, targeted treatment can be carried out.

The above are some common reasons for jujube fruit drop. Jujube fruit drop is relatively common, and before this everyone had better first distinguish whether it is natural fruit drop. If there are cases matching the above fruit drop situations, everyone should quickly treat the fruit tree.
