How to Tell if your Kale is Bad?

There are a few signs that your kale is terrible. The first is that the leaves are slimy, and the stem is brown. This signifies that the kale is past its prime and should be discarded. If you find a few black spots on the leaves, you can trim the remaining leaves. However, if you find that the majority of the kales have slime, it’s best to throw them out.

Another way to know if your kale is past its prime is to look at the color.
