Cucumbers are essential vegetables on our dinner table. They are crisp and cool raw, and each has his own favorite. In summer, the climate temperature is suitable. You can plant several plants on the balcony by yourself, beautiful and practical.

If the cucumber leaves grown on the balcony turn yellow, what is the cause? Let's take a look:

1. Overwatering

If the heart is too urgent, I always hope it will grow up quickly, and it will be watered too much! However, if there is too much water, the water can not be absorbed and discharged, the excess water is stored in the basin soil, the roots are stuffy and airtight, it will be damaged and rotten, and the leaves of the plants will turn yellow, and there will be more and more yellow leaves. more serious will cause cucumber plant wilting and even death.

Therefore, it can not be watered many times, as long as keep the soil moist, or see dry wet also, so that the plant root system can be normally extended and absorbed, can work normally, plant growth ability is exuberant.

2. Excessive fertilization or insufficient nutrition

There is a lot of demand for fertilizer in the growth process of cucumber, but the amount of fertilizer used can not be increased at will. If you fertilize too much, the excess fertilizer plants can not absorb, it will be stored in the basin soil, high-temperature transpiration, it will burn the root system of the plant, burn the root! Once the root is damaged, it can not absorb nutrients normally, lack of nutrients will lead to the emergence of yellow leaves.

Therefore, fertilization must be appropriate. Phosphorus and potassium fertilizer can be used in bud stage and melon setting stage, two to three times a month. This fertilizer is beneficial to plant root absorption and can increase production.

On the other hand, if you use too little fertilizer, do not fertilize it after planting, and allow it to develop on its own, the nutrients in the basin soil are almost absorbed, and if the nutrition of the cucumber plant is not reached, it will also have yellow leaves. At this time, the plant is thin and slim. The face is yellow and muscle is lethargic, and the cucumber with a big head and a small head cannot look directly at it.

3. Lack of trace elements

Cucumber growth period, also need a lot of trace elements, such as magnesium, iron, zinc, calcium and so on, if the growth is missing, the leaves will also be yellow. It is suggested that some special foliar fertilizer for cucumber should be sprayed during the growing period to supplement these trace elements and improve the quality of cucumber.

4. Diseases and insect pests

Cucumber long insects, mostly concentrated on the leaves, resulting in yellow-green mottled leaves, yellow leaves, flower leaves or deciduous leaves.

Usually, it is necessary to observe the growth state of the plant and find that there are insects to be controlled in time. If there are not many bugs, you can use vegetables with spicy flavors such as garlic, chili peppers and ginger, smash and rinse and mix them, and then spray the whole body of the plant. or high liquor diluted with water and sprayed, the effect is good. If the pest is serious, it will have to be sprayed with special insecticides to control it.

There is also a possibility that it is a natural phenomenon in the growing period, which, like human metabolism, grows new leaves, and the old leaves at the bottom of the plant will slowly turn yellow and fall off because of lack of light and nutrition. This is a normal phenomenon, and you don't have to worry about it.

Cucumber yellow leaves of these imaginations, are relatively common, early detection, early correction, cucumber can return to the normal state! When your balcony is covered with strips of cucumbers, are you very happy, too?
