I have a white pineapple (sugarloaf pineapple), and a papaya tree that that were growing all spring and summer in Salt Lake City, UT. They were both doing very well, and I was planning on taking them down to my parents who live in a warmer climate for the fall and winter. However, we unexpectedly got a cold front recently and both plants were subjected to temps of 28 degrees F (-2 degrees C), and both looked sick the next morning. Since then I’ve been bringing them inside at night, and back out in the warm sunlight during the day. Do you think they’ll survive? Or is it too late?
