My fourth tomato plant cut down by a cut worm. I thought this one was too big for cut worms, but I guess not. Look at the stem. It looks like a beaver chewed it. If you look close by the green arrow in the photo, you will see the little rascal that did the damage. He is no longer with us. I stuck the plant back in the dirt with a 'we'll see' attitude. It does not look so good right now.
