Although it may seem like a good idea to leave the snow on to act as an insulating layer (it was 8oC inside mine today and
-3ºC outside), it isn’t!
A twitter friend @northcountryken who owns an organic farm in Newcastle, England posted pictures of one of his collapsed tunnels yesterday where they’ve been having very severe snowfall – several feet in places. It was a sight none of us would like to see in our own gardens, but even worse if it’s your livelihood.
You can see from my pics that it doesn’t need a massive layer to put pressure on the plastic, so if you’re able to get to your tunnel, try and remove as much snow as you can with a soft brush.
When the snow has cleared, check the plastic. If you notice any tears or holes repair it promptly with special repair tape that you should be able to pick up from your local garden supplier or polytunnel supplier. As polythene ages it can become brittle so repairing tears promptly will prevent them from getting bigger, therefore prolonging the life of your tunnel.
