Mary Grace Canfield, a veteran character actress who played handywoman Ralph Monroe on the television show “Green Acres,” died of lung cancer on Saturday at a hospice in Santa Barbara, Calif. She was 89.

During a four-decade career, Canfield appeared on TV shows including “General Hospital” and “The Hathaways.” She was Harriet Kravitz on four episodes of the 1960s series “Bewitched.”

But she was best known for her role of Ralph Monroe in some 40 episodes of “Green Acres,” which ran from 1965 to 1971.

Monroe greeted folks in the town of Hooterville with a cheery “howdy doody,” wore painters’ overalls and was forever working on the Douglas family’s bedroom with her brother, Alf.
