Prevent Deer Damage in Your Garden | Gardening Advice
Physically excluding these animals is the best way to prevent deer damage. But when deer become sufficiently desperate, they may learn to jump your barrier. Many types of fencing can work, including single- or multiple-wire strands at varying heights, electric fences, plastic or metal mesh attached to trees or posts, and solid structures made of wood or metal.
