What are the latest reasons why zucchini does not set fruit?
Zucchini is a fairly common vegetable at present, with an enormous planting base, and one of the more serious problems is failure to set fruit, which can cause zucchini yields to decline over the long term. Let's take a look below at what causes this problem!
1. Insufficient light
Light is an extremely important factor for this type of fruiting vegetable; without sufficient light, fruit will fail to set, and zucchini will fail to set fruit for this reason as well. Attentive growers will notice that if the weather is bad or there is continuous rain during the fruiting period of zucchini, the number of fruits on the plants will drop sharply, or even no fruit will set at all. Therefore, choosing good weather for planting zucchini is extremely important; at the very least, plant only after the rainy season.
2. Excess nitrogen fertilizer
Nitrogen fertilizer is one of the fertilizers most commonly used by growers, and its greatest role is to promote the plant's own growth. But some growers blindly assume that as long as the zucchini seedlings grow well, there will be more fruit, so they apply rather a lot of nitrogen fertilizer; in fact, this is wrong. When nitrogen fertilizer is excessive for zucchini, the nutrients are absorbed only by the stems and leaves and do not go to the fruit, ultimately resulting in very lush plants that then fail to set fruit. A moderate amount of nitrogen fertilizer is best.
3. Overwatering
Zucchini has a relatively high demand for water, because water can promote the rapid growth of zucchini, and growth in a moist environment is always much better than when water is lacking. Because of this characteristic, when zucchini is in extremely moist conditions, it will grow excessively, that is, the seedlings run to vines, with no fruit. Although vegetables need water, the consequence of overwatering is exactly this, so growers should not water blindly.
4. Insufficient pollination
Pollination is also a major obstacle to zucchini fruiting; pollination during the flowering period affects the number of fruits later on. If pollination during the flowering period is not ideal, or the weather is poor, so that normal pollination cannot occur, then growers had best carry out hand pollination, as only this can ensure the fruit-setting rate. The timing of hand pollination must be grasped well, and it is best concentrated at the peak of flowering, when the success rate is highest.
The above are some of the more common reasons why zucchini does not set fruit. In addition, there are some less common factors that can also have an effect, such as seed problems and so on. Growers should first clarify the situation; treating the cause accordingly is the best choice.
