Answer: Plastic bags are never a good option for shrubs or trees. They can hold in too much moisture and cause fungal diseases. And, they aren't very good insulators from the cold. Most fruit trees can handle some frosty weather. You can leave yours alone and plan to prune out any winter damage or, if the predicted frost is short (a few hours) you can drape an old sheet or blanket over the top of the tree. If frosty weather is expected to last for several days, don't bother with the protective covering. Instead, prune away the damaged branches when new growth begins in the spring. Best wishes with your fruit tree.
