Julie I'm vaguely remembering an older gentleman with suspenders who was very relaxing to watch (not the Cajun Chef). But I don't recall if the entire program was gardening or just a segment. It was on PBS but I think it was a local one in NC. Or maybe it was when I was a kid in NY? I can't really remember.
There's a younger guy now who recently got his own line of plants. I can't remember his name either but that's because he was just a bit too relaxing for my taste. I could only watch a few minutes until I got bored. Maybe P. Allen something?
