Dig bulbs and dry for several days. Cut off tops and roots and store in a cool, dry place. Harvest green onions when they are 6 to 8 inches tall. Peppers Peppers are shiny green in their prime and about the size of a baseball. They still are good after turning red or yellow.
Hot peppers are red or yellow when ripe.
Sweet Potatoes Sweet potatoes should be harvested before the first frost. Lift to avoid bruises and broken roots. Cure in a warm well-ventilated place for 2 to 3 weeks. Radishes Pull them up when they are about 1 inch in diameter. Radishes become hot and tough when left in the garden too long.
