Will a paper bag protect my potted plants (herbs and flowers) from frost?

We've got a frost warning for tonight and of course, I've already planted all of my Spring herbs, veggies, and flowers. I've read that a bedsheet will work and I plan to use that with my herbs and tomatoes that are planted in a nice row on my deck. However, I have a couple of freestanding pots here and there (2 on the front porch, 3 more on the deck but separate from the others) that are too small for covering with a sheet. These pots are all small enough that I could easily fit an inverted paper bag over them without smushing the plants. Will a paper (grocery) bag protect them from frost, or should I use something else?

It should be fine. Really, if they're near a building they'll probably stay warm enough without a covering, but a paper bag will protect it from wind chill if it gets windy. I usually just line all my pots up against the house and just worry about covering bed plants that can't be moved.

Frost? Yep, should be fine.

If it were a hard frost, however, I'd go for something else. Black plastic, for instance.

And by "hard frost," I really meant "hard freeze."

Yes. Make sure everything is well watered.

Thanks guys! Best answers all around. The plants aren't really next to the house - they're against the far deck railing, and the deck is a full story off the ground, so I'd rather not chance it.

Oh, and they've all been well watered. It seems like we've had non-stop rain here lately. The plants are all doing so well I'd hate to see them die now!

We're worried about our garden in Boston, too... Gotta love spring weather!

You can make protective cloches from soda bottles, too. Then they're reusable, and they let the sunshine in on those chilly late-spring days.
