    At what temp do gardeners consider there to be a frost? I watch the weather forecasts daily and when it says 1 degree i respond as that could drop to zero and zero and below is a frost as far as me and my car windscreen are concerned.

    But for gardening purposes should I consider slightly higher temps as frost?

    Did warn you it was a daft question and I don't think I have explained myself very well.

    Cheers - I have been warned tonight will be cold up here in the North East.

      Good afternoon @GYO newbie this is the official version:smile:

      A ground frost refers to the formation of ice on the ground, objects or trees, whose surface have a temperature below the freezing point of water. During situations when the ground cools quicker than the air, a ground frost can occur without an air frost. A grass frost, an un-official type of ground frost, can occur when other surfaces - such as concrete or road surfaces - don't experience a frost, due to their better ability at holding onto any warmth. It is possible for a grass frost to occur in late spring or even early summer when the risk of more wide-spread frosts has disappeared and is something that gardeners in particular need to be aware of.

      This is Woos version when my furry friend penny refuses to go in to the garden last thing at night:heehee:

        Wonderful - so not such a stupid question then.

        So anything circa 2 or 3 degrees needs to be monitored.

        Ta!

          You can get a "Ground" frost even though the air temperature is 3C, so you need to be ready to cover tender plants as they will suffer. Usually you see the grass with frost on it. Air frosts are when the temp drops to zero or lower, depending on humidity levels you might or might not get ice on your car windscreen. Both types are bad for plants, but the "Ground" frosts are the ones that catch us gardeners out at this time of year as the weather forecast temperatures don't give us a clue. Usually it's clear nights when you need to be wary.

              Hi Harry. Not that professional yet. Only been dabbling since mid Feb for the very very first time. Never grown a thing in my life. It is going well. Well things are growing - whether something edible comes along is another matter.

              I have windowsills, a patio with tubs - a small plastic non-heated grow home and garden fleece and bubble wrap. If this year goes well and i have to say i am really enjoying it - then i may invest in more in a greenhouse. For now though it is a rustic approach. ALready spent a small fortune of tubs, compost, seeds, raised beds, two grown homes, covers, netting etc etc etc. Hubby wants to see a return on my investment!!!!

                It does cost a bit of money when you first start . Once you get your kit though its not to bad in the following years . Lots of information on growing on the internet , plus you have here to help as well :blue thumb:

                    I'm in the same situation as you, a total noob but learning all the time! I use www.ifttt.com which emails me when the temperature is expected to be 2c or lower at which point I cover stuff that is particularly vulnerable. :)

                      Great tip Sarah - will sign up to that now.

                      Yeah a noob. Was advised to start slow but I soon ran away with excitement my list is similar to yours on another thread:

                      Various types of potatoes
                      Carrots
                      Round carrots
                      Onions from seed and sets
                      Beetroot
                      Broccoli - reg and purple
                      Butternut squash (haven't sowed these yet but have the seeds)
                      Courgettes
                      Cherry toms
                      Melons
                      Blueberries
                      Strawberries
                      Cucumber
                      Sweet corn
                      Apple trees - gala, holder delicious, red delicious.
                      Williams pear
                      Several kinds of lettuce
                      Radish
                      Broad beans
                      Runner beans
                      Peas
                      Sugar snap
                      Mangetout
                      Cucamelon
                      Salad peppers
                      Chilli's
                      Herbs

                      Think that's it - ha, its a lot. Loving it though. Lord knows if I am doing anything right. This forum does help - but I myself then have to implement what I have been told and that's often where the problem lies!!!!!!!!! Hee hee hee

                        Also take into consideration the wind chill:blue thumb: I know it seems a faff but anything even down to news paper thrown over outdoor stuff will help on things you can't bring in:thumbsup: I won't be happy until there's at least a constant 9/10 degrees overnight:dbgrtmb:
