The best time and correct method for removing leaves from cucumber plants
Cucumber is a very common gourd vegetable in our daily life. It is grown in all parts of our country. When growing cucumbers, in order to avoid consuming too many nutrients and improve the air circulation of the plants, the work of removing leaves from cucumbers is very important. So when is the best time to remove leaves from cucumbers? And how should the leaves be removed? Below, the editor brings you the timing and methods for removing leaves from cucumbers. Let's take a look together!
1. Why remove leaves
When growing cucumbers, in order to extend the fruiting period of the cucumbers as much as possible, we generally need to lower the vines. Before lowering the vines, we need to remove all the old leaves on the lower part of the plants. If the old leaves are not removed in time, the air circulation in the lower part of the plants will be too poor, the air will not flow, the humidity will increase, and disease resistance will decrease. The old leaves are also very susceptible to infection by pathogens and disease. Therefore, everyone must pay attention to doing the leaf removal work well to ensure the normal growth of the cucumber plants.
2. Time for removing leaves
When removing leaves, the timing is also very important. If the timing of leaf removal is improper, it will not only fail to help the growth of the plants, but may also have adverse effects. Therefore, when we remove leaves, we should do it in the morning on a sunny day, and we must ensure there is no dew on the plants. If leaves are removed in the morning when there is a lot of dew, the wounds on the leaves are very likely to be infected by bacteria. If leaves are removed in the evening, the wounds heal slowly or even cannot heal, and at night the humidity increases, which also easily leads to bacterial infection and disease.
3. Parts to remove leaves from
When removing leaves, we also need to pay attention to which parts of the cucumber to remove leaves from. Counting from the top of the cucumber when starting to remove leaves, then starting from around the 15th leaf, remove leaves that have turned yellow, old withered leaves, leaves with yellow spots, and some leaves with pests and diseases. The number of leaves removed each time must not be too many, and should be kept at around 3. If too many leaves are removed, the cucumber plants will experience a relatively serious bleeding sap phenomenon. And the plants need a large amount of nutrients, so the cucumbers will gradually stop growing.
4. Method for removing leaves
The main targets for leaf removal have just been mentioned. For healthy leaves that are dark green and free of pests and diseases, they can be removed. The interval between each leaf removal should be at least around 5 days. When removing leaves, be careful to keep the petiole. If the petiole is removed together, it may affect the stem vine and cause injury to the stem vine. If the petiole is kept on the plant, the petiole will automatically turn yellow and gradually separate from the stem vine. And even if the wound becomes infected, it can be discovered in time, avoiding damage to the stem vine.
The above is a brief introduction to the timing and methods for removing leaves from cucumbers. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
