Wrapping tree trunks in plastic is the best way to ward off damage by rabbits and voles this winter, writes Jeff Gillman, associate professor of horticulture at the University of Minnesota. Castor oil repellents also prevent four-footed creatures from munching on trees and plants. "Remember, there's no sure-fire way to completely rid your garden of pests, even in the winter," Gillman writes. "But with time and a never-say-die attitude, you can prevent them from doing their worst."
