Potato damage

Last year's new potatoes were a disaster due to frost damage. This time, determined not to be caught out, I carefully placed a plastic tunnel over the bed to keep the crop safe. The spuds have been drawn into early growth by a lengthy warm spell, followed by a cooler period and a couple of frosts, so I was glad I had thought to add protection. On checking the progress yesterday, I can confirm that the tunnel was bloody useless and the young leaves have all been burned to a crisp. Luckily, they do still seem to be growing strongly, so ditched the tunnel and earthed up instead. Let's see if that does the trick, if not, next time I'm going to have to put the potatoes in the ground much later and see if that works.
