This is my first year growing. My plants are in pots and are still producing , so for the 2 or 3 nights it was below freezing this year I brought them into the garage and would bring them back out when I got home from work the next day, they only missed one day of sun. How long can they stay in the garage if we have an extended cold spell. Being in pots, if I can pull off back and forth with the garage and weather there would be no need to cut them back right?
