Fencing in a garden is easy with wire mesh fencing, which comes in varying heights for different jobs. You also can purchase mesh with different sizes of holes to accommodate your needs. For instance, a 3- or 4-foot-high garden fence can be made with 4-inch mesh gaps. A fence that protects a garden from deer will need a higher fence than this.
Lay out the garden area. Mark each corner with a stake and tie the string to each stake, marking out the outer edges. Keep the string low to the ground or high enough so it is not a trip hazard.
Drive a fence post into the ground at each corner using the sledgehammer. If you encounter rocks or other hard debris under the ground, you might have to pull out the post and try again an inch or two over. Bury the post deep enough in the ground to support the weight of the fence when it is pulled tight. Metal fence posts that are made for this project have an extra 2-foot section at the bottom that is meant to be driven into the ground.
Measure the distance between each corner post and divide that by either six or eight feet, whichever measurement you have decided will be between the posts. The closer you put your posts, the more support your fence has. If you are trying to keep out dogs and larger animals, keep the posts closer together. If you are trying to keep out rabbits, eight feet apart should be fine. Lay a post at every interval on the ground, with the bottom marking where the posts should go.
Drive the posts into the ground at the marked spots using the sledgehammer. Measure each post to be sure you are making them level with each other. If you are hanging a 4-foot-tall fence, your posts should be 4 feet out of the ground. Adjust posts as necessary to be sure they are all the same height.
Wearing work gloves to avoid being stabbed by loose pieces of wire, unroll a 6- or 8-foot portion of the roll of fencing and stand the roll up on end next to the first post.
Secure the end of the fencing to the corner post by bending it around the post and securing it into the clips that are pre-manufactured on the post. To help secure the fence, feed a 6- to 8-inch piece of wire through the pre-drilled holes in the fence post and wrap the wire tightly around the post and the fence to hold them together. Secure the fence in several places along the post.
Unwrap more fencing from the roll and stand it next to the next post. Pull the fence tightly between the two posts and secure the fence to the second post. Try to get the fencing as tight as possible and secure it the same way, using the clips and wire pieces. Continue this process along the rest of the fence posts until you have wrapped the whole garden in fencing. Leave the last stake open to allow for a gate.
Pull the fencing across the opening and cut it about six inches longer than necessary to cover the hole.
Cut the last row of vertical wires away from the fencing. This will leave you with long horizontal tendrils of wire hanging off the end of your fence.
Bend these wires inward to form a hook with each horizontal piece of fence. Hook these bent pieces around the secured fence that is attached to the first post. Use these bent hooks as the latch to open and close the fence. You also can design a gate out of PVC pipe or boards.
