What non-lethal methods work best to keep city squirrels away from tomatoes?
It is a serious problem here. I wouldn't mind sharing some tomatoes, but the
squirrels here are very rude and do not share. And actually taunt. Taking
a bite out of a perfectly good tomato and then leaving it.

Building a wire cage probably is the best method, but I hear they can even
get through those. And I'm not all that handy at building things.

Last year, putting soaking a rag with vinegar about every 3 or so days
seemed to work for a while. Though at the end of the summer, even that was
not deterring them that well.
