Grass Frost ? When did BBC invent that..
Discussion
Grass frost is used to describe when the air will be cold enough to form frost on vegetation but not on concrete or paved areas as these surfaces retain heat from the day for longer. This is useful for gardeners to know to help protect plants as grass frosts can occur early into autumn well before you may start to put away delicate plants into the greenhouse.
Rather than Google an answer, or even just ask, you actually took the time to weave this into an anti-BBC rant, well done.

"When the temperature at ground level falls below 0 °C, it is called a ground frost. Interestingly, meteorological office weather stations have thermometers set over both grass and concrete, as the difference between temperature over the two can be great: on still, clear nights, with air of a low humidity content, there may be a difference of five degrees Celsius.
For this reason, you may hear the unofficial term grass frost in weather forecasts – this is to try to avoid panic by road, railway and airport operators but alert gardeners and growers to the risk of damage."

Not content with their pathetically inaccurate weather ‘forecasts’. Which are amended 5 minutes before the storm they didn’t forecast...
Ground Frost has been rebranded Grass Frost.
Why the hell did they need to change a term that has been around since god was a boy?
Pathetic
It's not been "rebranded", they are different things.Ground Frost has been rebranded Grass Frost.

Is it not because they don't want to use the term 'hoar frost'?
Hoar frost is very different.https://www.metoffice.gov.uk/learning/frost/types-...
