The UK has already experienced some of the heaviest widespread early snow for 17 years. The deep freeze has seen a record low where sub-zero temperatures have reached double-figures and it has been reported that the snow is going to stay right through Christmas and New Year! (Oh Joy!)
Whilst growth in the Polytunnel is now slow to non existent, the Polytunnel gardener should still protect all tender crops from extreme temperatures. Adding cloche hoops covered in fleece, or a mini polytunnel covered in polythene over raised beds inside your already exsisting Polytunnel like “double glazing” can help protect frost sensitive plants. You might also want to consider the use of a thermostat controlled propane gas heater to take the edge off the cold inside the Polytunnel.

Although a light layer of snow can provide some insulation, snow is heavy stuff! Remember to gently remove any lying snow from the roof and sides of your Polytunnel with a soft brush. A good bang on the inside of your polytunnel with the back of your hand also works a treat – don’t let it accumulate!
Crop bars are the perfect addition to any Polytunnel. These horizontal galvanized steel supports are fixed across the width of your tunnel at head height. They serve a multitude of purposes from supporting hanging baskets, canes and wires to strengthening the Polytunnel structure against wind on blustery sites and helping with snow load.

Polytunnels are FANTASTIC!!
Our Begonia’s take the stage.
Thanks to the new crop bars on the “old” tunnel (ordered through First Tunnels replacement tube design system) and all the bars in the newer one, they all stood up well to the recent weather.
