What is the reason why pomegranates only blossom and do not bear fruit?

Pomegranate is a very popular fruit in our life. There is a great market demand, and now the planting area of pomegranate is also very large. When planting pomegranate, there are often many problems affecting the growth of pomegranate, resulting in a great impact on the yield and quality of pomegranate. And pomegranate only blossoms but does not bear fruit is one of them. So what is the reason why the pomegranate only blossoms and does not bear fruit? Let's take a look at it.

1. Insufficient pollination trees

When planting pomegranate trees, we should pay attention to the provision of an appropriate number of pollination trees around. If there is no corresponding pollination tree around the pomegranate tree, then it will be an inevitable phenomenon that the pomegranate will only blossom and not bear fruit. Therefore, when we plant, we should plant according to the ratio of main varieties to pollinated varieties at 5:8. If there is no place to plant pollination trees, then high grafting should also be carried out on the main varieties of pomegranate trees. High grafting varieties are mainly pollinated varieties, and artificial pollination should be done to improve the flower and fruit rate of pomegranate trees.

2. Late frost wind damage

In the process of growth, if pomegranate trees encounter late frost, strong wind damage and drug damage, it will lead to the phenomenon of falling flowers and fruits, and sometimes only blossom but not bear fruit. In order to prevent these phenomena, we should make corresponding preparations. For example, in order to reduce the harm of late frost, it is necessary to delay the release of cold protection, cover the tree plate and irrigate to reduce the temperature and soil temperature of pomegranate trees. Delay the florescence until there is no harm from late frost, and postpone the flowering of pomegranate trees.

3. Malnutrition

Pomegranate tree demand for nutrition is actually relatively large, in the pomegranate tree growth period, if there is no adequate nutrition for pomegranate, resulting in insufficient nutrition of the tree. Then it will affect the flowering development of pomegranate trees and hinder the pollination and fertilization of pomegranate trees. Therefore, we should pay attention to fertilizing well and apply nitrogen fertilizer once about ten days before flowering. Boron is very important to the growth of pomegranate, so appropriate amount of borax and urea should be applied at flowering stage to promote the germination of pomegranate pollen grains and increase the rate of fruit setting.

4. Fruit trees grow excessively

There are many varieties of pomegranate, and sometimes if the pomegranate only blossoms but does not bear fruit, it is probably because of the variety. After the nutrition of the pomegranate is taken away by the new shoots, the young fruit will gradually drop off because of the lack of adequate nutrition. So for some overgrown trees, we use pruning, ring-cutting and other pruning methods to control the growth of the tree and concentrate the nutrition on the fruit. If the tree is too weak, then all the flowers and fruits should be removed in time, and the rest and recuperation of the tree should be carried out.

The above is a brief introduction to the reason why pomegranate only blossoms and does not bear fruit. That's all for today's introduction. This article is for reference only. I hope it can be helpful to all of you.
