The bad news is, deer can jump high. Even an 8-foot-tall wire fence may not be enough to keep a determined deer out of your garden. The good news is, while deer may be able to jump high, they do not jump far. This means that two lower fences, double fences as low as 4 feet, can be enough to deter even a hungry deer from your garden, if they are properly spaced.
Drive stakes into the ground using a hammer. Wrap 4-foot-high wire netting around the stakes. Use metal ties to tie the netting to the stakes so it is secure.
Pound in stakes 4 feet further out than the first fence and wrap 4-foot-high wire netting around these stakes as well. Secure this second fence to the stakes with metal ties. This creates two fences with a 4-foot space between them. The space is not enough for a deer to get a running jump over the second fence so the deer will not jump the first fence. An adult should be able to step over each fence, so no gate is required.
Tie Mylar ribbons to the outside of the two fences so that the ribbons will move when there is a breeze. The movement will be an additional deterrent to the deer.
Plant deer-repellent plants in the space between the two fences to deter the deer further. Some deer-repellent plants include: baby's breath, lavender, St. John's wort, spearmint and sage.
