Ground Cherries are open branched plants that kind of half sprawl. This variety, in my experience, grows about 2 feet tall by 2-3ft wide in part sun. I plant them around garden boarders so I can easily pick the husks once they fall from the plant.
To harvest ground cherries, wait until the husk falls from the plant and pick them from the ground. But you could have guessed that. They will be at their sweetest then. If you harvest sooner than that, they will be more tart, which some prefer. Don’t be afraid to try them at different levels of ripeness. Although I don’t recommend eating them green.
