To protect your growing plants in the garden from a cold, harsh, unexpected frost, reach into your recycling bin and fish out a plastic water bottle. Cut off the bottom of the bottle (about 1 inch from the bottom) and place the cut side into the ground, surrounding the seedling. The water bottle will act as a greenhouse of sorts and protect the seedling from the frost. When the threat of frost is over, remove the bottle and recycle it as you normally would.
