Every night they come in the house. We've had temperatures below 30F the past few nights, but I'm going to trust the weatherman when he says we'll be in the 40s by tomorrow night. There isn't a freeze warning for tonight, but it's close enough that I'm not taking a chance, so I brought the plants in one last time! Tomorrow they will all get planted in the garden (except for those in containers). Ten tomato plants and 11 peppers were already planted last week, and they survived the low temperatures just fine with minimal cover. *Update, the local TV station is just now forecasting 29F for tonight.
