From Anne:

For several years I’ve enjoyed listening to an excellent gardening show
on the radio.  It is a nationally syndicated show produced at the Rodale
Institute Radio Studio in Bethlehem, PA. The host is Mike McGrath who is
the former Editor-in-Chief of Organic Gardening magazine.  The show is
touted as a “weekly dose of chemical-free horticultural hijinks” and is
full of valuable information on all topics related to growing
things—lawns, ornamental bushes and trees, vegetables, etc.  The show
is titled “You Bet Your Garden,” and current as well as past episodes
can be viewed online at wlvt.org.

I just watched Episode 79 where the central question had to do with the
difference between tomato blight and wilt and how to prevent them.  The
live show is a call-in where people can ask their own questions, ending
with a focus on the question or topic of the week.  McGrath is
knowledgeable, entertaining, and informative.  I have learned a ton from
tuning in.
