HAMBURG, Pa. â Judy Henderson doubted her green thumb as she struggled to keep her potted indoor plants alive. That was until she grew her first batch of microgreens. After moving to Berks County three years ago and setting up her little farmette, Humming Hills Farm, her garden and small microgreen operation flourished. The short growing cycle suited her well, she said, as âI like quick results.â Judy Henderson with her packaged microgreens.

At the start of the year, she was recovering from two hip surgeries and using her down time to research more about the microgreens that were growing in her basement.
