In gardening, preserving the onion crop is one of the top priorities.
However, sometimes we encounter a problem when the tips of the onions start to turn yellow.
What can cause this phenomenon and how to prevent it? Let's consider the main reasons for yellowing onion tips and provide effective solutions for preserving the harvest, says Anastasia Kovrizhnykh .
Nutrient deficiencies
The reason for the yellowing of the tips of onions may be due to a lack of certain nutrients, such as nitrogen, potassium and iron.
To eliminate this problem, you need to feed the plant with suitable fertilizers that contain these essential elements.
Regular feeding of onions with specialized fertilizers will help strengthen the plant and prevent yellowing of the tips.
Lack of moisture
Yellowing of onion tips can be caused by insufficient moisture. Onions are a crop that requires regular watering, especially at the stage of active development.
Make sure that the soil around the onion is always moist, but do not allow it to become overwatered. Regular watering according to the plant's needs will help prevent the tips from drying out and turning yellow.
Diseases and pests
Certain diseases and insects can be responsible for yellowing of onion tips.
For example, fusarium, rot and aphids can cause tip discoloration and plant damage.
To prevent these problems, inspect plants regularly, remove affected bulbs, and apply appropriate control measures such as insecticides or fungicides.
To maintain a healthy onion crop and avoid yellowing tips, you need to provide the plant with the necessary amount of nutrients, maintain optimal soil moisture, and combat potential diseases and pests.
Careful care of plants and constant monitoring will help maintain their health and ensure a rich harvest.
