Insulating your greenhouse with bubblewrap

    I haven't used bubble wrap in my greenhouse for years. Aside from the faff, l found it increased the level of moisture even if l left a window open in milder weather.
    Mine is a cold greenhouse as opposed to frost free and l wouldn't use a heater even "back in the day" when energy costs were lower.

    I much prefer using a layer of fleece, or more if exceptionally cold weather is forecast. As soon as the temperature starts to rise during the day, l take it off and replace it at dusk.

    If you did decide to use bubble wrap, it's better to use horticultural/greenhouse stuff as opposed to the type used for packing.
    My mother in law hasn't used her greenhouse for years, and when my OH tried to remove the bubble wrap, as mentioned above it just disintegrated into dust with loads of little round pieces of plastic everywhere.

    Hi,AnniD, depends where you live as well of course, which is why we usually ask the newcomers. Just popped out and taken a picture of the scented pelargoniums in my front south facing garden, they've been in about 8 years, don't get any winter protection. Shame, the other day there was a lot more flowers. A few years ago, I bought some green fleece on e bay. A roll used it to line our bottom green house,I didn't bother to remove it in winter,as you say "too much faff"(as I've now got 4) it lasted a few years,till it disintegrated.so it shaded from the sun and gave frost protection. Oh,Lynfromthrsea,rose cuttings can just be pushed into a spare bit of soil

    I seem to remember Lyn saying she lived in an area of Devon where palm trees line the streets winter and summer.  I could be muddling her with someone else! 
    My bubble wrap disintegrated as Anni D said.
    I also bought some bubble stuff that had a silver reflective backing,  like the stuff you put behind radiators,   I used in the GH to shade the tomatoes,  works very well but that disintegrated as well.

    Thank you for your advice Anni but I did have a chuckle at your description of your bubble wrap as I can just imagine how I’d react to that!

    Thank you for taking the time to answer my request. I would put my roses in the ground if we weren’t intending on moving. I took cuttings of all my roses (most of which have taken) and many other cuttings too, with the intention of taking them with us. We would need a separate van for all my pots etc!! But now our house sale has fallen through, due the chain collapsing, I think I will leave them where they are for the time being.

    No that’s not me I’m afraid Lyn. We live in South Somerset in a very rural environment but we do get quite a few heavy frosts and dreadful winds. I’ve lost quite a few trees due to the extreme weather conditions so I now make sure they don’t suffer in the drought and they are quite secure in the wind.
  • I was sceptical - but it does seem to work. I'm giving it a try in the greenhouse this winter.

  • I line the back and floor of my lean too greenhouse with the silver backed bubble wrap you buy for car windscreens, works great ( you also get one without the bubble wrap, but it has a light layer of polystyrene type material on the back) easy to manipulate and just rolls up for storage later. On really cold night I supplement with a double layer of fleece over the pélargoniums.

    How long have you had your silver backed wrap Jacqui? Mine went to dust.

  • Three years so far, I bought them in lidle, not expensive at all.
