Garlic leaves turning yellow and drying at the tips may be due to reasons such as continuous cropping, early sowing, pest and disease damage, or insufficient nutrition. When growing garlic, it is important to adopt the method of crop rotation, choosing fields previously planted with watermelons or rice to grow garlic, and to sow when the temperature is around 12 degrees Celsius, while also providing compound fertilizers to supplement nutrition.
Why Do Garlic Leaves Turn Yellow and Dry at the Tips
1. -- Continuous Cropping --
Garlic leaves turning yellow and drying at the tips may be due to continuous cropping. Continuous cropping leads to a reduction in the necessary nutrients in the soil for garlic, causing the second batch of garlic to grow poorly. It's best to use the method of crop rotation when planting, choosing fields that have previously been planted with watermelons or rice.
2. -- Early Sowing --
Garlic leaves turning yellow and drying at the tips may be due to early sowing. Garlic thrives in a warm environment, and sowing too early can result in low environmental temperatures that affect the growth of garlic seedlings. Therefore, it is best to choose a time when the temperature is around 20 degrees Celsius for planting garlic to ensure the seeds germinate and grow smoothly.
3. -- Pest and Disease --
Garlic leaves turning yellow and drying at the tips may be due to pest and disease damage. Although garlic has strong disease resistance, providing fresh manure during cultivation can lead to fly maggots attacking garlic, resulting in yellowing and drying at the tips. It is necessary to spray insecticides on garlic in a timely manner to eliminate fly maggots and clean up severely diseased garlic seedlings.
4. -- Insufficient Nutrition --
Garlic leaves turning yellow and drying at the tips may be due to insufficient nutrition. Garlic requires a large amount of nutrients during growth, and insufficient fertilization can lead to weak plant growth and yellowing leaves. At this time, it is necessary to mix nitrogenous, phosphorus, and potassium fertilizers into the soil where garlic is planted, and to water the field to allow the plants to absorb balanced nutrition.
That is all the content about why garlic leaves turn yellow and dry at the tips. I hope it can help you, and I also hope everyone will come to see more green plant and flower experience and common sense!
