left that other site :" When WGBH (PBS) had its first gardening show, it was called “The Victory Garden”. "

I think that you are referring to Crockett's Victory Garden on WGBH; present by James Underwood Crockett.
In our family, we referred to him as :" Saint Crockett"; I reluctantly handed down my original "Crockett's Victory Garden " book to my son.
Crockett presented everything from companion planting, scheduling, crop rotation, explaining NPK (Nitrogen/Phosphorus/Potassium) fertilizers, inter cropping,
cold frame construction into a 'Hot Frame (with manure), dividing perennials, composting, etc., etc.
Always informative, and never talking down to novices, and was always very patient, even answered mailed-in questions to the TV station, etc.
Below is a very brief video of Crockett at work :

YES! It WAS “Crocket’s” Victory Garden. I hadn’t remembered the name, but you brought it back to my mind.
