We haven't seen the butterflies, but we know they have been here.  

 

Cabbage whites are very noticeable flittering around in the garden, so I don't know how we missed them.  But they lay their eggs on the underside of the leaves of all the Brassicas.  I noticed all the caterpillar poop in the kale, so I started looking for the feeding caterpillars.  And here they are:  GROSS!!!

 

You really can't see any damage yet, but as they get bigger, they eat more, and leave huge holes in the kale leaves.  We have to get rid of them SOON!!!  

 

We use a biological insecticide, Bacillus thuringiensis, we just call it Bt, that disrupts the digestive system of the worms.  It doesn't kill the butterflies, or any other critters, including us, just worms.  Worms have an enzyme in their stomachs that reacts with these bacteria, and they stop eating our kale.  Really, that's a nice way of saying that Bt causes paralysis.  

 

Anyway, Bt is approved for organic gardening.  So we use it.  

 

 

HAPPY GARDENING!!!
