Spring, summer, fall and winter: Vermonters celebrate the four seasons in a multitude of ways. Farm to Ballet seeks to honor the impact those fluctuating temperatures have on cultivators with a “year in the life”-style production. Dancers twist and leap their way through the story of seasons on a Vermont farm, from the return of geese to rituals of planting, irrigating and harvesting the crops. Conceived and directed by Chatch Pregger, formerly of Boston Ballet, the series returns for its second season beginning on Saturday at the Philo Ridge Farm in Charlotte. Gear up for kicking cows, lilting lettuce and pigs en pointe.
