Why doesn't the loofah bear fruit?

1. The ambient temperature is too high

1. Reason: The fruiting period of loofah is in summer and autumn, but the fruiting rate in autumn is higher than that in summer. This is because it is a plant that likes a warm environment. If the temperature where it is grown is too high, it will affect its pollination process and thus affect its normal fruiting.

2. Treatment method: Find a way to lower the temperature where it is kept. If it is a potted plant, you can move it to a place with slightly lower temperature. If it is grown in a greenhouse, you can increase the frequency of watering and spray water appropriately to lower the temperature in the greenhouse.

2. Excessive growth of branches and leaves

1. Reason: If excessive nitrogen fertilizer is applied during the plant's growing season, it will grow particularly vigorously. This will also cause it to use more nutrients for the growth of branches and leaves, thereby reducing the fruiting rate.

2. Treatment method: Change the flower fertilizer when fertilizing, and use one with a higher phosphorus content. In addition, if its branches and leaves grow particularly well, you can also spray some growth inhibitors to slow down the growth of its branches and leaves so that more nutrients can be used for fruiting.

3. Difficulty in natural pollination

1. Reason: If there are too many male flowers and too few female flowers on the plant, the chance of natural pollination will be very low, and it will be difficult for it to bear fruit.

2. Treatment method: Dip some pollen and apply it to the stigma to help it complete the pollination process.
