Question
I have had a Dwarf Patio Orange Tree for about 6 years and a Meyers Lemon for 2 years.  I live in upstate New York.  In the winters, on above 40 degree days, I usually put them outside to get some sun.  I find they don't loose as many leaves in the winter when I do this.  Well about a month ago I forgot about them and left them out for the night.  The temperature dropped down to about 28.  When I brought them in they dropped all their leaves and fruit.  The branches are very brittle and some break off every time I bring them in and out of the house.  I have been watering them and putting them outside hoping they will comeback.  But I have not seen any sign of life.  Will they come back?  If so how long will it take?  Thanks for any help and/or advise you can give.

Answer
Hi Diane, scratch the bark at soil level, if it is brown, then your trees are indeed dead; if the bark shows green , then they are still viable and need to be given more time. Citrus can't take temps that cold, so I am inclined to think the worse. Nick
