Why Melons Don't Set Fruit and How to Fix It

Muskmelon, also called Oriental melon, is an annual plant of the Cucurbitaceae family. Muskmelons have good adaptability and are grown throughout China, and in recent years muskmelons have sold quite well on the market. So what should you do when melons don't set fruit? What causes it?

1. Causes of muskmelons not setting fruit

There are many causes of muskmelons not setting fruit. For example, too many female flowers and too few male flowers, or too many male flowers and too few female flowers, will affect pollination, so naturally the plant very likely won't set fruit. Improper fertilization can also cause the vines to grow excessively, which likewise prevents fruit set. Poor nutrition causes the growing tips of the vines to compete with young fruits for nutrients, leading to fruit drop. If the growing environment is unsuitable, such as temperature, moisture, soil and light, these factors can also affect fruit set in muskmelons, and some pests and diseases have a very large impact on fruit set in muskmelons as well. These are all causes of muskmelons not setting fruit.

2. The relationship between muskmelon growth and fruit set

The growth of muskmelons has a very large impact on fruit set, and it can be said that the two have a mutually dependent relationship. The vigor of stem and leaf growth in muskmelons is closely related to how many fruits are set, but this does not mean that the more vigorously the stems and leaves grow, the more fruits will be set. Secondly, muskmelons need to be pruned during the growing process, which also regulates the relationship between growth and fruit set. This is mainly to control vine growth and increase the fruit-setting rate, so when growing muskmelons, the relationship between growth and fruit set is also a subject that must be studied.

3. Prevention and control methods for muskmelons not setting fruit

The measures taken differ according to the different causes of muskmelons not setting fruit. Do a good job of tidying the vines and pinching off the growing tips, as this can regulate nutrient supply and improve the relationship between vegetative growth and young fruit growth. Use fertilizer reasonably, do not apply nitrogen fertilizer alone, and combine it with phosphorus and potassium fertilizers and boron fertilizer. At the same time, under the condition of sufficient basal fertilizer, apply reasonable topdressing. When the ratio of male to female flowers is poor, hand pollination can be used to increase the fruit-setting rate. Reasonably control water supply and spray in combination with growth-regulating hormones, which can increase the fruit-setting rate.

4. Planting precautions

When growing muskmelons, there are also many points that need attention so as to ensure the fruit-setting rate of muskmelons. Generally speaking, when choosing agricultural chemicals for muskmelons, buy them from legitimate manufacturers and use them according to the directions and ratios in the instructions. For hand pollination of muskmelons, there are specialized pollination agents, so do not choose the wrong pollination agent. Pollination is generally done after four or six o'clock in the afternoon.
