If memory serves, POD’s not-too-distant relatives toiled in southwest Michigan’s celery flats. Fast forward a few generations, travel several hundred miles to the east, bunker in for yet another nippy weekend and growing celery indoors doesn’t sound like such a bad idea. This Pennsport gardener and her trusty knife-wielding sidekick hacked off the end of a nice fresh bunch and stuck it in a bowl of warm water. With any luck, fresh shoots and roots will emerge in a week or so.
