I have put plant cozys on my frozen tomato plants to see if they will catch up with the others. They are filled with water, and circle around the plant, and red is supposed to set more tomatoes. We'll see.

If you happen to see some of these in a garden someplace, you are going to feel so smart when you explain just what they are to the people around you - JoAnne, where do you find these things. Will be interesting to see if they work.
