How to prepare plants for frost?
I think it's going to be 37 degrees tonight.....do I need to cover my plants? I have a few tomato plants, a pepper plant, and 2 citrus trees(lemon & grapefruit). Or can I wait until it gets colder? It will probably get warmer again, so I don't want to bring them inside yet. They're in pots out on my balcony. Can I just cover them with garbage bags or something??
