It's America's happiest gardening show, Bob Tanem In The Garden with Edie Tanem.  We broadcast live on 810 am KSFO on Sunday mornings at 9:00; sometimes we have a guest but some days -- today, for example --we just take calls and talk about stuff in, around and for the garden.

Concerned about recent cold snaps?  The tip of the day came from caller Neil at the very end of the show, who suggested "heat tape" -- a product originally designed for use to prevent pipes from freezing, it plugs in to 110 power and comes on automatically at 38° F, and shuts off at 40° F.  Neil says you can put it at the base of trees or wherever you're concerned about frost damage.  Of course Edie reiterated Bob's old trick of using incandescent holiday light strings for a similar purpose, though those are getting harder to find; LEDs don't produce enough heat to help.
