This isn't the prettiest picture, but it is interesting.  

 

You can see that the old kale at the bottom is completely chewed up by the Cabbage White worms, but the pretty blue part above it is NEW growth.  And the new growth hasn't been touched.  

 

I guess I better harvest it soon, if we are going to have any kale this year.  

 

 

HAPPY GARDENING!!!
