Missing lettuce, whose fault?
I garden at a community garden and a single head of bibb lettuce has gone missing. My plot is surrounded by a 5 ft 12 gauge wire fence. I had 8 bibb lettuce together in 2 rows and they are near mature size. One is missing at the end of a row. There are also other lettuce in the plot, mainly romaine type, all intact.
I generally haven't had problem with human theft there and since there is just one head missing I suspect it isn't a person. What would do this kind of damage to lettuce? I have had a few lettuce eaten to the ground earlier during the season but haven't had any issues since. Any help will be appreciated!!
