Why are the tips of your garlic plant leaves turning yellow?

Nutrient deficiency: Garlic plants require a balanced supply of nutrients, including nitrogen, phosphorus, potassium, and sulfur, to grow healthy and green. If the soil is deficient in any of these nutrients, it can cause the tips of the leaves to turn yellow.

Water stress: Garlic plants need regular watering, especially during hot and dry weather. If the soil is too dry, the leaves will start to wilt and turn yellow.

Sunlight: Garlic plants need plenty of sunlight to produce chlorophyll, which gives the leaves their green color. If the plants are not getting enough sunlight, the leaves can turn yellow.

Disease: Fungal diseases, such as Botrytis and Fusarium, can also cause the leaves of garlic plants to turn yellow. These diseases can be spread through water, soil, or contact with infected plants.

Insects: Some insects, such as aphids and thrips, can feed on the leaves of garlic plants and cause them to turn yellow.

Herbicide damage: If you have used a herbicide near your garlic plants, it may have damaged the leaves and caused them to turn yellow.

Harvesting: If you are harvesting the garlic scapes, the leaves may start to turn yellow as the plant focuses its energy on producing bulbs.
