PRODUCTS: DEER FENCE GROUND STAKES, WARNING FLAGS, AND WEED BARRIER
Use ground stakes (item 18-01, 18-02, or 18-02A) to secure the bottom flap of the deer fence to the ground (see Deer Fence Installation: Securing the Fence Bottom), placing one stake about every six feet along the fence line. This may seem like a minor matter, but it's really important. Most fence penetrations happen not because deer go over or through the fence but because they nose their way under the bottom. So it's well worth sacrificing 6 inches of height in your 7.5 or 8 foot deer fencing in order to secure the fence bottom really well. These stakes are intended for that purpose, the 12-inchers being suited to most soils and the 18-inchers being best for light, dry, and sandy soils. For welded wire fences that have no bottom fold and that are seeking to keep out elk or other large animals, insert one ground stake about every 4 feet along the fence line.
Here's another small but key accessory. Deer will have trouble seeing a properly installed deer fence. You don't want them to find it by running into it--or even by bumping into it, because that will convince them it's not dangerous and may encourage them to explore and find out how high it goes, thereby increasing the possibility of their eventually jumping over. Use these warning flags (two per 20-foot fence section) when the fence is first installed and for three months or so thereafter in order to show deer roughly where the fence is and to warn them away from it. These small white flags somewhat resemble the white "flash" a white-tail deer shows by raising its tail to warn its companions of danger (see Deer Fence Installation: Warning the Deer Away). Tie them onto the fence at roughly waist height, and in no case higher than 4 feet.
Here's a gardening tool that goes really well with deer fences. Do you fret about weeds and vines growing into your fence, or grass growing up next to the fence and creating problems for your mower? If not perhaps you should. You can lick these problems by laying this thin plastic sheeting down under the fence before you install it. Then, once the fence is up, cover the sheeting with an inch or so of wood chips or pine bark mulch. That way the sheeting will keep down the weeds and the wood chips or bark mulch will protect the sheeting from the sun, allowing it to last for many years. This is especially important if you're planning a garden fence to be removed seasonally, because typically the biggest difficulty with such a fence is removing grass and weeds that have become entangled in its bottom without damaging the fence. A weed barrier greatly reduces or eliminates this problem.
Our 1.3 mil sheeting comes in 3 x 50 foot rolls. However, you don't need a strip that wide to protect a deer fence. So you may wish to fold it into a 1.5-foot width before you install it, or if you are thrifty you may wish to cut it lengthwise with a scissors (easily done) into two 1.5 foot sections.
This sheeting is not covered in our videos, but it's easy to install. Merely lay it down straight along the fence line, being sure it covers the area where your fence's 6-inch bottom fold will go. As you lay it down, keep it from being blown away with small stones. Then install the fence on top of it. It's that simple.
