Why does a pomegranate only bloom but not bear fruit?

The pomegranate is a very popular fruit in our daily lives. It has a large market demand, and the pomegranate planting area is now very large as well. When growing pomegranates, many problems often arise that affect the growth of the pomegranate, causing both yield and quality to suffer greatly. A pomegranate that only blooms but does not bear fruit is one of these problems. So what causes a pomegranate to only bloom but not bear fruit? Let's take a look below!

1. Insufficient pollinizer trees

When planting pomegranate trees, we must make sure to have an appropriate number of pollinizer trees nearby. If there are no corresponding pollinizer trees around the pomegranate trees, then a pomegranate only blooming but not bearing fruit will be an inevitable phenomenon. Therefore, when planting, we should plant according to a ratio of 5:8 between the main cultivar and the pollinizer cultivars. If there is no space to plant pollinizer trees, then top-grafting should also be carried out on the pomegranate trees of the main cultivar. The top-grafted cultivars should mainly be pollinizer cultivars, and artificial pollination should also be done well to increase the flowering and fruiting rate of the pomegranate trees.

2. Late frost and wind damage

During the growth of pomegranate trees, if they encounter late frost, strong wind damage, or phytotoxicity, this will cause flower and fruit drop in the pomegranate trees, and sometimes they will also only bloom but not bear fruit. To prevent these phenomena, we should do the corresponding preparatory work. For example, to reduce the harm of late frost, the time for removing the tree's cold-protection materials should be appropriately delayed, and methods such as covering the tree dish and irrigation should be used to lower the temperature of the pomegranate tree and the soil temperature. Delay the flowering period until there is no danger of late frost, thereby postponing the flowering period of the pomegranate trees.

3. Malnutrition

The pomegranate tree's demand for nutrients is actually quite large. During the growth period of the pomegranate tree, if sufficient nutrients are not provided for the pomegranate, causing insufficient tree nutrition, then it will affect the flowering development of the pomegranate tree and block pollination and fertilization of the pomegranate. Therefore, we must pay attention to doing the fertilization work well. About ten days before flowering, apply a topdressing of nitrogen fertilizer. The boron element is very important for the growth of the pomegranate, so during the flowering period, an appropriate amount of borax and urea should be applied to promote the germination of pomegranate pollen grains, which can increase the fruit-setting rate.

4. Excessive vegetative growth of the fruit tree

There are many varieties of pomegranate, and sometimes when a pomegranate only blooms but does not bear fruit, it is very likely due to the variety. After the nutrients used by the pomegranate for fruiting are taken away by new shoots, the young fruit will gradually drop because it lacks sufficient nutrients. So for some trees with excessively vigorous growth, we use pruning methods such as pinching and ringing to control the tree's growth and concentrate the nutrients on the fruit. If the tree is too weak, then all flowers and fruits should be thinned in time to carry out the tree's recuperation work.

The above is a brief introduction to what causes a pomegranate to only bloom but not bear fruit. That is all for today's introduction. This article is for reference only, and we hope it can be of some help to everyone.
