Thanks to all of you who responded to my question about wood chips. Several mentioned that certain kinds of trees, especially black walnut, produce some chemical which discourages competition from other plants.  That is intriguing.  I'm a pharmacist and, of course, antibiotics are from molds and bacteria which produce chemicals to reduce competition.  Now you say trees do it, too.  I wonder, has any research been done on these chemicals--it seems they might be very fruitful in producing herbicides.  Jerry in southern Indiana
