Hi all, 

Been growing vegetables and subtropical container plants for a long time and 
have seen plenty of frost-blackened vegetables outdoors.  What I don't 
understand very well is why 28 degrees in my sunporch didn't harm my tomato 
plants the other night and 24 last night didn't seem to affect my 
subtropicals--guava, jaboticaba etc.  The frost formation is more deadly than 
the sub-freezing temperatures?
