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.
