Night time temps. are forecast to dip to 2-3C in Bruton over the first w/e in May. Do you put fleece on tomatoes, etc. in the poly tunnel? Even in sunny Exmouth a low of 3C is forecast. My tunnel has permanent ventilation gaps above the doors so I can’t seal it shut.
I see that your 30/4 update has the answer, so I shall have my fleece for the poly tunnel at the ready over the weekend.
Thank you again for your most informative website including the twice monthly updates which I look forward to almost as much as I did with the Tiger magazine, featuring Roy of the Rovers, 60+ years ago!
