Diatomaceous Earth for your garden

As my husband and I expand our garden this year, we realize that critters abound who are set on destroying all of our hard work.  Many folks recommended a natural insect killer called food grade diatomaceous earth, or food grade DE.  Thus far, we have seen great results in keeping the destructive critters away.  I am not good at explaining how DE works, but I want to send you to a DE LINK that I know you will find helpful and extremely informative!  The gentleman 'in the know' is named Paul Wheaton, and I'm thankful for his expertise!
