Philadelphia has long been a gardeners' paradise, by East Coast standards anyway. The City of Brotherly Love enjoys relatively short winters and extended fall and spring seasons that aren't so wet and warm that they invite plagues of the pests that rule farther south. It's not surprising then that urban agriculture has deep roots here -- ones planted long before the recent national renaissance. But Philly's homegrown ag movement isn't just about getting more local produce into farmers markets. (Not that there's anything wrong with that!) It's focused on farming as a source of jobs and skills for city residents as well as a means to provide them affordable, healthy food.
