Why does cucumber bloom but not set fruit?

Cucumber is a popular vegetable that is widely grown throughout the country. Traditionally, cucumber planting and harvesting are mainly concentrated in spring, summer and autumn, but with the continuous advancement of greenhouse cultivation technology, we can now grow and enjoy cucumbers at any time, even in winter. However, during the planting process, some vegetable farmers found that their cucumber plants only bloomed but did not bear fruit. Let’s learn in detail why cucumbers bloom but do not set fruit.

1. Choose suitable seeds or seedlings

It is recommended to purchase seeds at a local agricultural supply store, or directly purchase ready-grown cucumber seedlings for planting. When purchasing online or from other places, be cautious and ensure the quality of the seeds or seedlings.

2. Reasonable control of water and fertilizer

Cucumbers are highly adaptable and do not require frequent watering and fertilization. Even in the summer when the temperature is high, you only need to water once every 5-7 days, and adjust according to the soil moisture when it rains. Reduce the use of nitrogen fertilizer and focus on the supplement of phosphorus fertilizer and potassium fertilizer. The required nutrients can be provided by spraying potassium dihydrogen phosphate and complete foliar fertilizer .

3. Control the vigorous growth of plants

For cucumbers that grow too vigorously, use growth control agents such as paclobutrazol and ethylenediaminetetrachloride in a timely manner, and use them strictly according to the product instructions to avoid overdosage.

4. Pest and disease control

Do a good job in preventing and treating diseases and pests. Aphids and thrips can be controlled with imidacloprid or thiamethoxam; downy mildew can be controlled with 72% cymoxanil·mancozeb; anthracnose can be controlled with 60% cypermethrin·mancozeb or 75% oxadiazine·tebuconazole; vine blight can be controlled with 30% benzyl·myclobutanil.

In short, the above are the main reasons why cucumbers only bloom but do not bear fruit and their countermeasures. Through these measures, we can effectively prevent and reduce the situation where cucumbers only bloom but do not bear fruit.
