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.

Pull out larger, whole plants or harvest older leaves to allow new growth. Squash should be 6 to 8 inches long with skin you can puncture with a fingernail.
