Yeah, I've always noticed that a little frost doesn't do much damage to the vegetable garden. It usually takes an actual freeze to end the growing season. We have a frost advisory here and the temp could get down to about 36 tonight, but I'm not too worried. My pole lima beans are producing like crazy right now, and I'm hoping they can keep going for at least 2 more weeks. Tomatoes, peppers and eggplants are still producing decently too. The light frost threat tonight shouldn't be a problem.
