Will frost hurt fruit trees?

Will fruit trees recover from frost?
It is expected that this tree will recover, but will miss a year of fruiting. Pruning will be postponed until March, when most of the twigs will be removed and branch tips will be headed back to live (green) wood. If a majority of the dead leaves fall soon after the freeze, the tree is likely to recover.
Does spraying trees with water prevent frost damage?
Plants that are drought-stressed often suffer more injury during freezes; however, watering does not actually provide any protection to tender plants. To protect plants with a covering of ice the spray of water must start just before freezing temperatures begin and continue constantly until they end.

Should I water my fruit trees before a freeze?

Why do fruit farmers spray their blossoms in spring against light night frost?
So, when a freeze is forecast for a citrus farm, the farmers often spray the trees with water. When the temperature drops, this water freezes and releases heat to its environment, some of which is the still-ripening fruit. This heat is enough to preserve the fruit inside from freezing.
How do farmers protect fruit from freezing?
We use overhead irrigation to protect the crops during a freeze event. When the temperatures drop to critical levels to damage the fruit buds, we spray water over them. As the water turns to ice, heat is released. The critical temperatures for damage depend on the crop and stage of development.
