|We have two three-year-old drawf peach trees. Is it okay to cover them with frost cloth? They are just about to flower. Our last frost date is April 18th. Days are running in low 60s, nights in the 20s. I was planning to keep them covered as long as possible.|
|It is a good idea to protect with frost cloth if frost is predicted, but to take it off during the day. You don't want temperatures to heat up too much beneath the covering. You also want pollinators to have easy access to the flowers. You can download this free publication from the University of Arizona Cooperative Extension, written by Lucy K. Bradley. It contains details on the best way to cover fruit trees. Good luck!
