At what temperature do apples freeze on the tree?

How do I protect my trees from sudden freeze?
Protect your trees and plants:
Cover susceptible trees and plants with burlap, sheets, tarps, etc., that extend to the ground to trap in the earth’s accumulated warmth. Use a frame or stakes to minimize contact between the cover and the foliage. Bring potted plants and trees to more protected locations.

Prune the apple tree every winter prior to new growth. Cut out any crossing branches, water spouts, and generally over-crowded areas.
Will frost hurt apple blossoms?
Answer: A late freeze in spring may damage the blossoms or developing fruit on apples, cherries, and other fruit trees. As a result, the fruit crop may be smaller than normal. The extent of damage will be determined by the plant species, stage of flower/fruit development, and temperature.
What happens if tree buds freeze?
Symptoms of freeze damage include shriveling and browning or blackening of damaged tissue. Damaged growth usually becomes limp. Eventually, damaged or destroyed leaves drop from the tree or shrub. Fortunately, trees and shrubs have the ability to leaf out again if the initial growth is damaged or destroyed.

Why do farmers spray water before a freeze?

Does spraying plants 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.
How do I protect my new trees in the winter?
Place a 4-inch layer of mulch around your tree’s base, spreading it out at least 2 feet from the trunk. Mulch protects your tree’s soil from frost and helps retain water so your tree’s root system receives adequate moisture. Remember not to let the mulch touch your tree’s trunk.
