Tomatoes - Harvest before frost. Wrap mature green tomatoes individually in newspaper and store in cellar where temperatures are 55-58 degrees Fahrenheit. Inspect for ripeness weekly. (Warm, moist 55-60 degrees Fahrenheit, 80%-85% relative humidity.)
At the end of the season place any green tomatoes indoors next to ripe bananas or apples. They contain a type of ripening agent that will help speed the reddening of your green fruit.
