I'm in the Knoxville area and just finished planting the rest of my tomatoes Sat. and my beans are about 2" tall. Wonder if it will hurt anything, even if there is no frost?

I don't know, I direct sown some big-boys and grape tomatoes last monday as well as a couple varieties of bell peppers into my raised beds thinking that I was safe to plant by 04/21 but apparently not. There's a good chance those seeds wont ever germinate at this rate, lol.

As for the rest of my seeds I direct sown last monday, most of them have sprouted up so now I'm in a hari kari to make sure they're protected for these next two nights. :sigh:

There's lots of us out here that 'thought' we were safe to plant now. I've got seedlings of brandy wine tomatoes in peat trays I started but I can bring those in. Guess I will get the newpapers out and cover my tomatoes that are in the ground. I bought pepper plants but was afraid to plant them. Glad I didn't. I can get those in the house tonight and tomorrow.
I'll be glad when the warm weather stays and we don't have to worry about this cold stuff anymore.

I've spent several hours yesterday and today putting out most of my house plants so they could get rained on. They're on their own so far as the frost goes! For tonight our Knoxville forecast is 40 as of a few minutes ago -- for tomorrow, 38. I think most things will get through it just fine, but I agree that covering the real heat lovers like tomatoes is probably a good "just in case" idea.

The weather channel is showing low 40's for Knox-vegas. All my orchids, Hoyas and the rest of the indoor gang are outside and have been since after the last cold snap. I think the ground is warm enough to endure an over night cold snap for the tenders. If it got into the 20's, I would do something about it. I have two maters in containers that might suffer a bit, but it is only two if I have to replace them.

It got down to 34°F here with a little frost on the truck this morning. I'm in NW Knoxville.

Well I had frost in the Solway community of west Knoxville this morning! I went out at 6:30 am and took the water hose and water down my tomatoes and beans before the sun hit them. We had a rain and wind storm about 11:00 last evening so covering them didn't help! Tonight frost warning again so I'm covering what I can and hoping for the best. Thank goodness I didn't plant my peppers and hot peppers! They're in the house :)
