Martha Stewart and Byron Martin - begonias 101
I watched the clip. It was great to see Martha cut down this super tall overgrown B. maculata wightii ( there must be some subliminal message from Butch for me).
For those of you in the St. Louis, MO area, Martha will talk about begonias with Lloyd Traven from Peaceful Tree Farms this Saturday March 6th at 8AM ( I think) on the Fine Living Network. My DVR is set to record already.
I don't think this show can be viewed online yet.
You can see Lloyd's Travelling Begonia Show on Martha's web site if you want to see it now. A few mistakes but overall pretty good.
Go to Martha's Greenhouses first (Lloyd comes in late on this segment) and then the begonias segment for more.
