I opened up my winter greens tunnel this afternoon, but it wasn’t a pretty sight. All the romaine lettuce was wilted and rotting. I guess the week of sub-zero temperatures was too cold for it. Plus it looks like a mouse had gotten in. There was a mouse nest and the iceberg lettuce and spinach were eaten and torn up. There were a number of holes chewed in the row cover and pieces of it were in the mouse nest. Arugula, mustard greens, and a rosemary plant looked OK. The soil was pretty dry. I left the tunnel open to get some rain. I don’t know how to get rid of that mouse. I suppose a mouse trap.
