growing greens

Question

my kale and collard green plants, constantly turn yellow all through the growing season…. what is the cause of that?

Answer 1

Yellowing could be caused by watering issues, but due to the fact that you are having this issue with different plants and you may have had this issue in past years, I would say a fungus issue.
