I have a young apricot tree that has fruit on it already here in Albuquerque, New Mexico. We have some nights coming up that temps will be 32°F (or 0°C - frost). Do I need to protect the tree if it already has fruit?
Apricots often lose blossoms and fruits to freezes. Some varieties do better in that situation. If you can protect them, that would be advisable.
If this turns out to be a frequent issue, or if your harvest doesn't survive, you might consider getting a nectacot. They're a cross between a nectarine and an apricot, but the one Gurney's sells (Honey Pearls) is supposed to be for zones 4-7 and flower later than apricots. They look pretty similar to apricots. I'm not sure what they taste like.
