I read a statement from a reputable website that stated information regarding mulch. It's wrong IMHO. Today's Garden Bite is about what NOT to use and the best types of mulch for your landscape. One type in particular for pest resistance and another that's renewable! Check it out. PS, I haven't used the particular website that I won't mention after seeing several missteps. Again, it's my opinion after gathering a lot more information and my own experience.
