Yes, but you don't need temperatures to be freezing to cause problems
for toms. At the moment in the SE it's barely getting above 50?F in the
day. and that's been the case for most of the past few weeks. That's not
warm enough to be on the safe side. Normally at this time of year I'd
have expected to see temperatures near 60?F by now in the south.

My melon and tomato plants in the greenhouse are looking ropey, let alone
anything outside. :-(
