No G in HGTV!
This was the subject of a recent thread on the perennial forum, and many posters remembered fondly the 'good old days' when American (and Canadian) gardening programs proliferated. They seem to be a rarity now.
One responder provided links to some British gardening shows on YouTube. That's not a resource I have ever made much use of - that has changed - I'm now a great fan of Alan Titchmarsh and Monty Don and the many beautifully filmed gardens. 'Around the World in 80 Gardens' is a great fix for cabin fever while we wait...
Kudos to the BBC. (Great accents too!)
