A Physical Barrier That Deer Cannot Jump Over

Be Exclusive

Damage done to vineyards by deer can be both extensive and expensive. Several types of fence materials are available that can help reduce and possibly eliminate the deer problem in the vineyard. There are lightweight fences made from extruded plastic mesh. Fences that are made with single strand wires, and woven wire mesh are also available. Each type has its advantages and disadvantages.

Plastic Fence Materials

Made from black, UV stabilized polypropylene, this extruded fence material has a mesh opening size of 2" x 1-3/4". The size of the rolls is 7-1/2' high x 164' long. The black color makes this deer fence virtually invisible when installed. Lightweight rolls are easy to work with. Although this fence can be torn and ripped if a deer charges through it or becomes entangled, the repair is fairly easy.

Easy to Use--Single Strand Wire

The fence material used for these fences is 12-1/2 gauge high tensile wire. There are two finishes available: Class 3 galvanized and zinc/aluminum with a black painted finish. Both have superior resistance to rust and corrosion and will last for years. Single strand wire fences for vineyards can be either vertical or slanted. Seven strands of wire are often used. The angled fence takes up more space. You can watch a video showing one installation. These fences are fairly inexpensive and easy to set up. 

A Fence that Endures

Woven wire fence materials for vineyards are available in a variety of heights, from 4' up to 10'. Woven from 12-1/2 gauge high tensile wires with heavy Class 3 galvanizing, these fences will last for years. Some specifications are available with a high rust and corrosion-resistant zinc/aluminum finish that is painted black. More attractive than bright galvanized wire, the black color becomes virtually invisible against the background. Woven fences are very strong and will not unravel. They are the most expensive and the hardest to install. Still, if you are a vintner, the security of knowing that your vines and grapes are safe is well worth this investment of time and resources.

Choices

With so many different types of fencing materials available, how do you know which one to choose? Are you overwhelmed when it comes time to make a decision? How do you know which one is the right choice?

Defining the Purpose of Your Fence

Most often, fences are used to either keep something in or keep something out of an area. But sometimes fences are used for decorative purposes or to define a boundary line or construction area. There are seasonal fences such as snow fences. And there are fences used to control drifting sand. The fencing materials you choose should be defined by the fence's purpose.

Fencing materials made from wire are the most common type available. The wire can be either woven or welded into a wide variety of mesh opening sizes.

Strong but Flexible--Woven Wire Mesh

There are woven meshes strong enough to contain livestock with different styles for specific types of animals. And there are deer and wildlife fences tall enough to keep out deer. Lighter gauge woven hex netting chicken wire meshes with black PVC coating can protect your poultry and fowl as well as your garden.

Welded Wire Meshes that Last

Use welded wire fencing materials to keep your pets and children in the yard. Vinyl-coated welded meshes make an attractive and long-lasting garden fence. There are many different wire gauges and mesh sizes from which to choose. Smaller meshes are ideal for animal cages and wildlife exclusion barriers.

Do you have any preference in fencing materials, woven or welded?  Which type has worked best for you?

Industrious, Hungry, and Not so Funny

They are the scourge of gardens, lawns, nurseries, athletic fields, orchards, golf courses, and other open public areas. Anyone who lives in an area infested with gophers knows the signs - the mounds of fresh soil dotting the ground's surface. One gopher can create several mounds in a day. Mounds can interfere with lawnmowers and severely impact the appearance of lawns. Conditions for digging are ideal in irrigated areas: flower beds, lawns, and gardens. Gophers love to eat:

• vines
• shrubs
• trees
• ornamental plants
• vegetables                                                                                                                                                                     

• A burrow system can cover an area of 200 to 2,000 square feet.
• Food storage and nesting areas can be as deep as six feet.
• Feeding burrows with a 3" diameter are most often 6" to 12" below ground.

Do you have a solution that's different from using gopher wire you'd like to share?

Chicken Wire in Production   

The video below shows how chicken wire mesh is woven. You can see how the wires are twisted together to make a hexagonal opening. Chicken wire is also known as poultry netting or hexagonal netting.

The Continuous Weave Creates Inherent Strength

This particular machine is weaving mesh used in making gabions. Although the mesh is larger (3") and the wires used are heavier (11 gauge and heavier) than the chicken wire you can buy at your local store, the manufacturing process is similar.

There is one difference. This machine is doing continuous weave -  the twisted wires run in the same direction the entire length of the twist. Chicken wire available in stores is made with a reverse twist - the twist switches direction (reverses itself) halfway through the length of the twist. Continuous weave is inherently stronger than reverse twist. Good to know.

Is this the first time you have seen a loom weaving chicken wire?

Which of these rolls of wire fence would you buy? Do they have the same footage? If they are the same, why do they look so different? Not all rolls are created equal.

The final diameter of a roll of welded or woven wire fence is determined by four things:

• mesh opening size
• the gauge of the wire used
• the size of the spindle upon which it is wound
• how tightly it is rolled at the end of the assembly line

In the example above, all three rolls of heavy woven wire fence are identical in mesh size, gauge, height, length, and weight. They even have the same core openings. And yet they appear to be completely different. The roll on the left is wound very tightly. It is almost half the diameter of the right-hand roll which is wound under less tension. If you were to buy one of these rolls, which would you choose? Would you prefer the smaller roll because it is more compact and easier to handle? Or would you choose the larger roll because it looks as if it has extra footage?

Checking the Weight

Different wire mills may have different size spindles. And they may roll their product under different tensions. So if you see wire fence products in the store that are labeled with the same gauge, mesh size, width, and length, they may look very different. A quick way to tell is to check the weight of each roll.

Imported wire fence is usually very tightly wound. Rolls have a small diameter hollow core. This saves space, allowing more rolls to fit on a pallet. Higher density per cubic foot enables more pieces to be loaded in a container, cutting the shipping cost per piece.
