This weeks' edition of Bob Tanem In The Garden features guest Robert Summers, who has an invention that could save a lot of trees; see www.rootquencher.com for more information about what he's talking about.   Other than that it's all phone calls all the time; America's Happy Gardener is on the air!  This podcast is an on-demand version of our on-air show; all the musical segments have been lifted to comply with licensing realities.
