It sounds weird defining the growing season by the first and last frost. What about the growth that occurs in between those 2 dates? You can still grow plants in winter.

The 5-6c mean threshold makes far more sense.
I agree... often here as well we'll have a frost and then a mild period will last quite a while where we won't have one.
Depends on what you're growing. Here in central ME, I'm getting ready to plant garlic. The hard part is guessing when it's two weeks before the ground freezes...it hit 26F air temp last night, so I'm guessing it won't be too long...I'll be screwed if we get another year where it doesn't happen before the first week of December
Interesting to hear about the Garlic. For here it's November that we have to plant them. And interesting to hear you got screwed by the warm December as well! I couldn't believe the Garlics were sprouting!

Still going here as well but my lowest was 39F. I forget, are you closer to NYC? All of Long Island has been below mid 40s as the season low except the Western end

It's called freeze here. Growing season doesn't end with a frost but does kill some crops. And Of course there are winter flowers and plants that can grow after the freeze or frost but a select few only.
Once a freeze (especially a hard freeze) happens, it's hard for plants to generate and produce again and therefore deemed end of growth.
Sure it gets mild in winter and some plants sprout but for how long and how many? Sun isn't out long either.
Another way to look at it, if you plant a seed after growing season ends, will that seed germinate?
For here, would have to be an extremely warm month like last year in December for something to germinate and sprout. But that's what it is "extreme", not normal. And its not like it had time to produce.
And I'm not 100% sure but growing season is more important for farmers than anyone else. Frost and Freeze is a curse word for them.
Lettuce also likes cool weather 40s/50sF but not a freeze.

36F seems like a warm temperature to end the growing season -there would be some very short growing seasons here. Tomato seeds here self germinate in the garden until about late April, so seeds will germinate after the end of the growing season.
Lettuce can handle the temperatures of a freeze, as long as it doesn't get frost forming on the leaves. I grow my winter ones in a tunnel house, and while it still gets -2C/-3C they grow well. I think the heat stored during the soil during the day, stops the moisture in the plant from freezing.

That's how NOAA defines it

I think this method are well valid for Eastern US and few others parts of the world only,while many others climates like in Patagonia/New Zealand that would not match well.
Getting frosts and freezes mixed up. Can still be some short growing seasons in some years, particularly down south, where mid summer freezes happen. I once visited friends near Albert Town, and they had lost tomatoes in a January freeze, then I was back about two months later, looking at the replacement plants with a good crop

As I told,the same thing happens in Patagonia,Towns like Bariloche,Esquel,Balmaceda get freezes even in mid summer.
