Backyard gardens will continue producing well into the fall, if gardeners take extra care with frost-sensitive plants.
Plants that originated in tropical or subtropical places -- tomatoes, peppers, summer squashes and cucumbers -- are among those that can't tolerate frost.
Frost-tolerant vegetables often originated in northern or temperate places. Those vegetables include broccoli, kohlrabi, cauliflower, Swiss chard, kale, cabbage, spinach, carrots, beets and turnips.
When frost is forecast, growers should water the soil around the frost-sensitive plants because wet soil holds more heat than dry soil.
Row covers can be made from many materials, such as old sheets, newspapers or old sheer curtains.
