    Minimum night temps for cukes?

    Okay so can't really keep the plants inside for much longer now as they're quite large. I've been bringing them in and out for a while now. Is it okay to plant them into there final growing position in the greenhouse yet? Also is there a minimum night temp I should look out for if I do?

    Thanks

    Advice on line always says 15C and over, dunno if they can wait for that LOL
    It's due to be a tad warmer by the weekend, here, so that's when mine are getting planted in the greenhouse border.

    If they commit Hara-kiri I'll just have to sow again

      Mine have been in the garden for 5 weeks and we've had lows of 6 and normally about 10 and they are fine. Having said that the temp was only that cold for an hour or so amd daytime temps have been low 20s. I would have thought they would be fine in a gh?

        mine have been in the (unheated) greenhouse for weeks now.
        They all have male and female flowers so can't be suffering too much (I do hope I haven't just tempted fate!)

          I'm still taking my cucs back into the kitchen at night the one time I left them in the GH the temp went down to 6c and my cucs went floppy they did recover later on in the day though.

            I have fruit developing on my cold greenhouse cucs. The temperature has been down to 8 degrees regularly, most recently on Sunday night. But as others have said, it doesn't stay cold for very long at this time of year.

            I planted out some Marketmore outside a couple of weeks ago. They have survived but they don't like it at all! They do have some flower buds though and I'm expecting them to pick up if we ever get some summer.

              Mine are going out over the next couple of days. Taking a chance, perhaps but cues are from India originally so I'll never, ever make it as nice for them here in West Kent. It's either that or them sulking in too small pots.

                Sounds like my market more. I had then out for a couple of nights which to start with had them looking ok but after the couple of nights they looked a bit sad. I have moved them into an outbuilding that gets plenty of sun through the big windows. They look a bit better now

                  Mine got too big to keep indoors I've planted mine in the ground. Under 10c and they've gone floppy (7 or 8) but I've been wrapping up with fleece if forecasts for 10 and under and they are looking ok. I picked two today

                    My cucs are still at the 1 true leaf stage, basking under grow lights in the spare bedroom. They are in fact smaller than the melons that were planted at the same time. Probably just as well really as I am full to bursting with tomatoes at the moment and have had to plant out some Sungold today with a cloche over them as the intended blowaway covers wouldn't stand up to this wind.

                    I think its going to be a case of get on with it and hope this summer - a few days ago we were promised a heatwave and all of the models were showing above average temperatures. But this is the latest run of the GFS today:

                    - far from a heatwave, the temperatures are struggling to get anywhere near normal (red line) for the time of year!

                      Well my tunnel hit 42C yesterday but it was too windy to risk opening any doors even a crack for most of the day. The overnight low was 7C. I'm hoping it's not at these temps for long, the tomatoes seem to be coping but the chillies are struggling and the aubergines are about to be thrown.

                      Thanks for the question Rhys - I've been wondering the same. I think I'll be erecting a trellis in the back room and putting grow lights on a Christmas light chain for the cucumber at this rate.

                        The min temp inside the poly last night was 5 degrees, so outside must have been close to freezing - which I knew by the frosty glistening on the grass early this morning.

                        horrible start to the growing year!

                          Mine are all outside now - I just cover with fleece and or a clay pot that has warmed up in the sun if the night temps look a bit iffy.
                          They are not dead but look like a 4 week holiday in the Maldives would do them some good.

                            Mine are in the gh and are going out on the weekend. I don't usually have problems with cukes, but these are really slow, on the second pair of true leaves after 5 weeks. I think my compost has been iffy this year too - am switching from Verve next year to MiracleGro or a bulk bag of something. It's a bit more expensive, but it seems to be worth it.

                              Thanks for the replies all, as Thelma said in an earlier post a minimum temp on 15 degrees at night is what's advertised when I look online, but their getting too big now and bringing them in and out is just more of a pain to be fair. Will be planting them out tomorrow and hopefully they'll be okay.

                              Thanks again
