What to Do When Chive Leaves Turn Yellow? Causes and Control Methods

Chives can be eaten in many ways and are rich in nutrients, making them highly favored by consumers, and they are grown over a very wide area. However, many vegetable growers report that chives show yellowing leaves during cultivation, and in severe cases all the chives in the entire field develop yellow leaves, causing great economic losses to the growers. So what causes yellow leaves in chives? How can it be solved? Let's take a look together with Qinnong Network.

I. Causes of Yellow Leaves

1. Lack of trace elements: Generally, when chives are grown, a lack of trace elements such as iron, copper and zinc will cause yellow leaves.

2. Excessive application of nitrogen fertilizer: Some vegetable growers, in order to make chives grow quickly and shorten the growth cycle, apply too much nitrogen fertilizer while neglecting other nutrients, causing an imbalance in the ratio of nitrogen, phosphorus and potassium fertilizers, which inhibits the roots' absorption and use of other elements, thus causing yellow leaves.

3. Excessive application of acidic fertilizers: Applying too much acidic fertilizer during fertilization acidifies the growing soil, hinders the growth and development of the root system, and impedes the smooth absorption of nutrients and water, leaving the chives in a state of malnutrition and causing yellow leaves.

4. No application of organic fertilizer: Some vegetable growers apply only chemical fertilizers and no organic or farmyard manure, causing trace elements in the soil to decline continuously, which leads to soil compaction and hardening into clods, poor permeability, and affects the respiration and absorption of the root system, causing yellow leaves and, in severe cases, large-scale death of the plants.

5. Improper watering: Excessive and blind watering makes the field humidity high or the soil waterlogged, and the soil permeability poor; likewise, the roots cannot breathe normally, resulting in malnutrition and yellow leaves.

6. Pests and diseases: Many pests and diseases can cause yellow leaves in chives and, in severe cases, normal death of the plants.

II. Control Measures

1. Rational fertilization: When fertilizing, in addition to a reasonable combination of nitrogen, phosphorus and potassium fertilizers, some organic fertilizer should also be appropriately added to ensure the content of trace elements in the soil so that chives can absorb and use them and receive a balanced supply of nutrients. In addition, fertilization should be based on each growth stage of the chives. In September to October, apply about 100-450 jin of organic fertilizer per mu, and spray foliar fertilizer several times, which will fully supply the trace elements the chives need. It is also important to avoid applying large amounts of acidic fertilizer. If the yellow leaves are caused by soil acidification, lime powder and plant ash can be scattered into the soil to adjust the pH and restore the soil to normal.

2. Rational watering: Watering should be based on the dryness and wetness of the soil and the weather. When the climate is dry and the soil is dry, water in time to keep the soil moist; when the soil has sufficient moisture, there is no need to water. Also, in rainy seasons, drain water in time to prevent waterlogging. In addition, watering should take the soil texture into account: generally sandy soil needs a shorter interval, while clayey soil needs a suitably longer interval. When watering, loosen the soil appropriately to increase permeability.

3. Pest and disease control: Pest and disease control should focus on prevention. Generally, during planting, the soil and seeds should be disinfected, and fertilizer and water management should be strengthened during cultivation to improve the disease resistance of the chives. When pests and diseases are found, deal with them promptly and apply the right remedy.
