  I could do with some advice on grass minimum temperatures.

For years, I have been trying to record this parameter.  I have tried using the grass minimum thermometer as suggested by the Met office and no using a Davis Soil Thermometer but still don't get the correct temperatures.

Last night - there was a patchy grass frost and yet my soil thermometer records 4.4oC.  How do I get this to record the correct temperature.  Some blades of grass must have been below 0oC?

Thanks

When I had one - not a Met Office approved one, mind you - I used to prop it up about 5cm above the ground using Y-shaped sticks at each end.

AFAIK grass minimum thermometers shouldn't be in touch with the ground... I'm guessing yours touched the ground directly?
