Rubbish bag plantation?

Actually it's field of Aloe Vera, which have been bagged to protect them from the freezing temperatures over these few days.
Very cold all day today. I didn't go far, and had a chat to the neighbours next door and up the road. Apparently there have been a few cases of Covid in Distos, a nearby village, which is the nearest it's ever been. The Distos primary school has now been closed as a precaution.
