Tammy Algood of the University of Tennessee Agricultural Extension Service shares some tips for preserving your fruit harvest. If your fruit trees are in bloom and frost is predicted, string outdoor Christmas lights through the trees to provide a heat source.
Larger bulbs work better than the small ones.
Another way to save your plants is to cover them with floating row covers. This is an especially good method for protecting vegetable crops such as tomatoes and squash. You can also use an old sheet, a blanket or even newspapers. Anchor the protective coverings with stones or bricks to prevent them from blowing off. Seedlings can be protected with plastic drinking cups.
