What are the main reasons winter melon does not set fruit

Winter melon is a large vegetable-type food; one winter melon is enough to feed a group of people for a long time, and winter melon has very good effects both in cooking and in health preservation. But winter melon failing to set fruit is indeed a problem for many growers. Qinnong Web takes everyone through some of the reasons winter melon does not set fruit.

1. Malnutrition

This is mostly caused by improper manual management. Winter melon needs fertilizing during both the vine-growing and flowering stages, and it should be done in small amounts many times, so that the fruit that forms is round and healthy in size. If nutrition cannot keep up in between, the flowers will not directly wither and die; they will remain in a flowering state the whole time, and only wither after the flowering period ends. The manifestation is that the flowers show no change for a long time, and the flower base shows no tendency to turn into fruit.

2. Little pollen from male flowers

This is mostly caused by natural weather conditions. The usual reason is that the temperature is too low and there is too much moisture in the air, so that male flowers have no pollen after blooming. This situation deserves special attention when flowering falls during a rainy period; at this time the temperature conditions need to be controlled manually to ensure the pollen production of male flowers. If the planting area is too large, it is best to carry out artificial pollination, and before flowering it is best to release some fertilizer that promotes pollen quantity to strengthen it.

3. Excessive flowers

Some novice growers think that the more flowers a winter melon has, the better, since that means more winter melons will grow. But they often overlook the nutrient supply capacity of the winter melon plant. The nutrients a single vine can supply are limited, and when there are too many flowers, each flower gets only a little and none of them can develop, ultimately wasting a good seedling for nothing. So when you find a mass of flowers blooming on the winter melon vine, you should immediately remove some in the right amount to ensure the nutrient supply for the other flowers.

4. Damage from pests and diseases

This uncontrollable factor is too great. Generally, if any disease appears and the flowers are infected, it will lead to no fruit set. Common symptoms are flowers drying up, or some mold spot symptoms, while some show flowers turning brown and splitting open. Of course, the most common is damage from pests, which damages the pistil and stamens so that pollination cannot succeed. For such situations it is generally recommended to treat the specific cause, spraying pesticide to solve the problem.

The above are the reasons winter melon blooms in daily cultivation but does not set fruit. When the above situations occur, everyone should deal with them promptly. Under normal circumstances the above problems are all fairly easy to solve; you just have to observe carefully. When planting, you should also avoid violating some of the taboos above.
