The weather was great for weeks and so I planted tomatoes in a planter (moveable) and now the weather is predicted to drop to freezing at night. There are several flowers on it now. Should I bring the plants inside until the weather changes?? Thanks for any help.

If there's frost in the forecast (there is here), bring 'em in at night.

My dad grows wonderful tomatoes and he babies them to death until the summer. If the planter is moveable I would bring them inside.

Dad keeps his tomato plants in individual pots. If the temps are supposed to drop through the night he will bring them in and then set them back out that morning.
