When do I need to protect a fruit tree from cold, and how do I do it?
We have several cherry trees and an apple tree in our back yard. Due to the very warm March we had (in Minnesota), they are all covered in flowers. In a few days, there is a chance of snow, and an overnight low of 26.
What do I need to do to protect them?
I saw When do I need to protect a fruit tree from cold, and how do I do it?, but I don't know if the difference between just starting to bud, and having flowers on them for a week or two is important.
