Rock Your Garden With Rock Dust! | Gardens Alive!
Q. I''ve been enjoying your program on our local NPR station, WSCL in Salisbury, MD. I ran across an intriguing article in the UK''s Independent about an apparently miraculous growth medium for plants called rock dust. Sounds like this stuff is right up there with corn gluten meal. I hope you have an opportunity look into this and perhaps comment on it in future broadcasts.
