When cucumbers start to bend, their market value tends to decrease. To maintain quality and prevent bending, there are several effective methods you can follow:

First, avoid removing too many lower leaves too early. The photosynthesis of the leaves plays a key role in the yield of cucumbers. As long as the lower leaves remain green, it's usually unnecessary to remove them prematurely.

Second, apply balanced fertilization techniques. Start with organic base fertilizer and maintain a ratio of N:P:K:Ca:Mg = 5:2:6:9:0.7. When using quick-acting fertilizers, make sure to supplement micronutrients like boron and zinc. To prevent early aging of roots and leaves, consider spraying a compound microbial foliar fertilizer at a dilution of 200 times, once every 7 days, and repeat this 2 to 3 times if needed.

Third, manage watering carefully. Water in smaller amounts each time, and ensure that the intervals between waterings are not too long, especially during hot periods.

Fourth, avoid overloading the plant with too many fruits. Excessive fruit production increases the stress on the plant. If too many fruits are left unharvested in the early stages, the leaves may age quickly, which can lead to bent cucumbers.

Finally, if some cucumbers have already started to bend, you can place small stones or bricks under them to support the stems. This method can help the cucumbers straighten naturally within about 7 days.
