tomato relocation program

tomato relocation program

My mother-in-law bought me three grape tomato plants several weeks ago and planted them for me in a large pot. They're doing pretty well, but they've gotten huge. My husband's friend said I need to separate them or they'll kill each other. It seems easy enough, but I'm not quite sure how to approach it. Do I just have to gently dig around them until I can lift them out? I assume they're pretty delicate as far as handling goes. Can I grasp the bottom of the plant and pull them out like that, or do I need to completely dig around the roots? Also, any other tips to assure their survival would be appreciated!
