    Default What temperature for frost?

    Hi all,

    I know this may sound like a stupid question but at what temperature do you actually get frost in your garden/Lottie etc.

    The reason I ask is because I just got a new min/max thermometer to put in one of my coldframes and it says that frost occurs about -20 degrees C or something like that.

    Any thoughts?

    I always assumed that frost appeared at freezing point 32F or 0 Deg C ?

    Default Frost

    Hello Fezinio. Good question about frost. I think there must be some mix up about about the temperatures you quote from your thermometer. -20 degrees C would be a record most parts of this country have never seen (but you could be in the Cairngorms). -17C is the record for this part of the country and I hope never to see it again
    The answer to your question is 0 degrees C is freezing point and you will get frost. Well that's according to the physicists. In reality you can get frost if the temperature falls below 4 degrees.

    In short - under 4 degrees C, take precautions
    0 degrees C, guaranteed.

    Hope this helps.

    Somethings not right Fez .Frost should appear around +1 deg or lower.
    -20 is the temperature of frozen food in the supermarket freezers.Could the label be stuck on the thermometer incorrectly?
    There comes a point in your life when you realize who matters, who never did, who won't anymore and who always will. Don't worry about people from your past, there's a reason why they didn't make it in your future.

    Thanks Alice and Snadger,

    I think I need to look at the thermometer again. Knowing me I have read it totally wrong.

    I would check now but all ready to settle for the evening and don't really want to tackle the cold in me shorts and t-shirt.

    Roll and grow your own veg at 8.PM and before I forget come on you rip roaring potters (Stoke City FC) who play in the FA Cup tonight
