I am in New Orleans
We had 26F temps last year.
i lost a lot of stuff, but my Longan was not phased.
it wasnt over 2ft tall either.
Loquat wont be bothered by anything above that temp either.
My Cherimoya both froze to the ground, but came back
(they were only 3ft tall)
if they are small, i would bring them in
I cant speak for the rest, but i understand Rambutan to be very sensitive.
New Orleans got the cold front yesterday and this morning.
it was 82F 2 days ago
today we have SLEET.
my little seedlings before i could get them inside.
Jaboticaba.
