How do you keep fruit trees alive in the winter?

Place a thermometer near the trees to monitor the cold, and make sure the temperature stays warm enough for them to survive. Another option is to bury the containers in soil or bark mulch and wrap the tops of the trees in burlap to help them survive the winter in a protected spot.

At what temperature do fruit trees go dormant?

This dormant period is only broken after the tree has experienced a certain amount of “chilling hours,” which are the cumulative number of hours when the temperature drops between 32 and 45℉.

Why do orange farmers spray water before a freeze?
