Cold is especially dangerous to citrus trees.Agricultural specialists at the University of California suggest putting paper or cloth around the trunk and central branches of young Citrus trees.
In Florida,as temperatures fell to record lows,citrus growers sprayed water on their trees to help prevent freeze damage.
Jim Bottcher is a master gardener with the University of Florida extension.He explains that as the water freezes,it produces heat,and the ice forms a protective blanket around the tree.If you spray a tree,keep the water away from nearby power lines.Heavy ice can form and break them.
You can also wrap a tree in palm tree frond leaves,corn stalks or fiberglass.Adding plastic film works well in rain and snow.But experts say plastic alone does not help much.
