From bed in her East Greenwich Township house, Katherine Vaczi can see through patio doors into the backyard flower and vegetable garden she has been tending for more than 40 years. The sight inspires the 81-year-old to get up and start her day. “There’s always something I need to do,” Vaczi, a retired teacher, said on a recent afternoon while showing her Gloucester County property to a visitor and pointing out where she had just cleared a bed of celosia after the seeds had dropped.
