The Victory Garden on the Fenway in Boston was still in operation when I was a child. My folks would point it out to me as we rode by it on the way downtown.
When WGBH (PBS) had its first gardening show, it was called “The Victory Garden”.
I LOVED ‘The Victory Garden.’ Marion had awesome kitchen knife skills, LOL!
I still see re-runs once in a great while on local PBS and old episodes are on YouTube.

The Victory Garden on the Fenway is still there.
What I was surprised to see was the gardens along the rail lines outside of cities like Zurich or Geneva in Switzerland.
People from the cities would rent land plots near the stations out in the Swiss countryside. Right along the side of the rail line. Then they would take the train out to tend their plot.
This was very common when I was there in July 1990.
The other place that is very conscience about growing their own food is on the island of Bermuda. There are 60K+ packed onto an island that is 25 miles long. Wherever there is not a golf course people grow all sorts of vegetables. Even if it is right in downtown Hamilton. Virtually everything on the island of Bermuda is imported.
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 :
