when to pick ground cherries
Pick ground cherries when they fall to the ground. Lift the branches of the plant to see the ground cherries hiding in the papery, buff-colored husks. Allow the ground cherries to remain in the husk, unrefrigerated, until you're ready to use the fruit. When left in the husk and stored in a cool, well-ventilated room, ground cherries become sweeter and last for up to six months.
