My mom has a problem with squirrels eating her tomato plants that she has right behind her deck.?

Is there anything you can put out or put on the ground or in the soil that will keep animals away but not hurt the plants? She doesn't have anything she can use to enclose the tomatoes and keep them totally isolated from rabbits, etc.My mom has a problem with squirrels eating her tomato plants that she has right behind her deck.?
Well, the green parts of the tomato plant are poisonous. She should have started the plants out of the garden until they got large enough that when a squirrel ate some, it would realize it was harmful and either leave the plants alone or die.My mom has a problem with squirrels eating her tomato plants that she has right behind her deck.?
