What Causes Yellow Kale Leaves

Posted on Jun 23 2010 - 3:13am by Mike Lieberman

I haven’t had the best of luck on my balcony garden. The oak greens were wiped out by cabbage worms and the purple kale had an aphid infestation.

Now the leaves on my kale containers are continuing to yellow. From what I’ve heard and read there a bunch of causes for the leaves of kale to yellow.

It could be a lack of nitrogen, so I added coffee grinds to help with the yellow leaves. That didn’t work.

I’ve also read that it could be because of poor drainage. I stopped watering them for a bit. That didn’t work.

Someone else said that it could be due to lack of watering. I watered more frequently. That didn’t work.

The most important thing is that kales are a decent size, so I am gonna harvest and eat them before the end of the week.

This is another reason that I don’t read many gardening books (except for “Grocery Gardening” ) and listen to the “experts” because there is no one right answer.

I’m sure there are a million other causes that people can think of for yellow kale leaves. What are they?
