I have several citrus in huge clay pots here in zone 9 (lake elsinore, socal) and the forecast is for rain and a low of 35 degrees. It rained heavily on Monday night, and I had put xmas lights and sheets over them before the rain began. They are OK, however, the sheets were so heavy with rain, I am reluctant to do it again. I have no plastic. Do you think they will be OK? Should I just turn on the xmas lights and leave them uncovered? Thanks for your advice!
