  • Advice on Using Polytunnel in Colder Weather

    First year growing so I'm still unsure of what I should be doing.

    It was cold last night and the fleece I laid over the tops of the veg growing in the PT was soaking wet when I came to remove it this morning. I was trying to keep the plants warmer but probably made things worse if they got wet under the fleecing.

    Should I be keeping a window open overnight now for ventilation or should I close it up completely overnight as I have been doing and just not add any fleece on top?

    Or am I worrying too much about it all

    You're worrying about it all............................I would close the doors at night but keep the fleece off unless a frost is forecast. Others may do different but that's my call.

      What crops are you trying to protect, Marie?

        Yes I thought I was probably worrying a bit

        Got spring onions in a bigger container which I wrapped in bubble wrap to keep temperature up

        individual containers of mooli radish, chinese cabbage, mustard spinach, raddichio, swiss chard, tatsoi, choy sum

        and a young raspberry plant in a pot

        The tomato plants are on the way out so not trying to protect those.

          Personally I wouldn't worry about fleecing anything inside the tunnel until/unless we get REALLY cold temps.

            OK good thank you. I've got some bubble wrap to line the inside of the tunnel which I might do in a month or so depending on the weather. Hope that will help with keeping it a fraction warmer.

            Last winter was very mild (we had snow for just half a day I think before it melted) but doesn't mean this year will be mild

              I would close the door at night, and with those you have listed tolerate low temperatures quite well. So i don´t think you have anything to worry about till hard frosts, if you get any.

                Thank you, that's good to know. Hopefully I won't kill them off then

                  Every time someone has a poly tunnel conversation, I have the urge to go and get some popcorn and just sit and read in wide-eyed and hopeless envy.... ggg

                    I would say all of the veggies you are growing would be fine outdoors so in a polytunnel they will be happy as Larry!

                      Just be careful how wet you keep the ground. A good water in the morning on a sunny day now and again will be fine, the ventilate well. I keep mine a bit on the dry side and it reduces the condensation problem

                        Thanks. Yes I am bad at over watering things and I guess as it gets cooler, you don't want things swimming in water. I bought a spray bottle for the spring onions because I was afraid I'd water them too much

                          You could also lay a few sheets of newspaper over them if you are worried.

                          And when your back stops aching,
                          And your hands begin to harden.
                          You will find yourself a partner,

                            Never thought of newspaper, good idea.

                              Personally I don't think there is any need to protect any of those things any more than the protection they're getting by the tunnel.

                              Some of us live in the past, always talking about back then. Some of us live in the future, always planning what we are going to do. And, then there are those, who neither look behind or ahead, but just enjoy the moment of right now.

                              Which one are you and is it how you want to be?
