What are the latest causes of fruit drop in jujube trees?

Jujube trees do have natural fruit drop. If only a small amount drops, this is normal behavior, but if the amount is larger, that indicates a problem. If there is a problem, what factors mainly cause it? Let's take a look below at several causes of fruit drop in jujube trees.

1. Insufficient fertilizer

This situation mainly occurs during the flower-to-fruit transition period, when 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 time, the jujube tree's demand for fertilizer is relatively high, and nutrients are supplied to the flowers and fruit 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.

2. Environmental factors

The environment also has a considerable impact on fruit drop in jujube trees. 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 receive sufficient sunlight and cannot bear too much fruit. 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 the environment leading to a water imbalance in 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, which is caused by excessive growth of the jujube tree. Such a jujube tree's own branches and leaves 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 fewer and fewer jujubes on the entire branch can obtain these nutrients. Finally, the fruit forms fruit drop due to insufficient nutrients. It is recommended that growers at this time prune the fruit tree to a certain extent to suppress this problem.

4. Diseases

Diseases are also a major key cause of fruit drop, and many pests and diseases can cause it. Jujube berry disease, jujube fruit shrink disease, jujube fruit rust disease, and so on can all cause relatively serious fruit drop. These diseases occur because the fruit is corroded by pathogens, then the vitality of the entire fruit declines, 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; after further judgment, targeted treatment can be carried out.

The above are some common causes of fruit drop in jujube trees. Fruit drop in jujube trees is relatively common. Before this, everyone should first identify whether it is natural fruit drop. If any of the above fruit drop situations apply, everyone should quickly treat the fruit tree.
