Keeping Your Garden Deer Free

Poly deer fencing, such as Tenax C-Flex is a great way to keep deer away from gardens, orchards and other areas of your property. When installed correctly the fence is highly effective, long lasting, durable and best of all virtually invisible. The black mesh doesn’t draw the eye and practically fades away into the background allowing you to enjoy unobstructed views of you property and surrounding areas.

Tenax fence comes in various weights and depending on the number of deer your property draws, as well as the size of the area you are wishing to protect, the heavier the fence should be. The height of the fence is also important. Deer are much more reluctant to jump over anything above eye level, so a height of 7.5 feet is recommended. However, equally as important is securing the bottom of the fence line with ground stakes as deer will dig under a fence before attempting to jump over it.


Step 1 – Corners and end posts

Install all corner posts and end posts first. Tenax fence can be installed using a variety of post options from wood to tubular metal posts or even using study healthy trees. For best results though the post should be buried 3 feet deep and match the height of the fence above ground.  Support end posts and corner posts with braces or support wires if needed.

Step 2 – Monofilament Line

Attach the monofilament line from each end or corner so that a line runs the entire span of the area the fence will be placed.


Use monofilament sleeves to secure the line to the posts. Slide the line though one side of the sleeve, then around the post then back into the other side of the sleeve. Use the crimping tool to close the sleeve and secure the line.  Repeat this process for both the top and bottom ends of the posts.


Install monofilament lighteners along every run of line top and bottom between posts.



Step 3 – Support Posts

Support posts should be installed every 15 to 20 feet. If deer traffic is heavy opt for 15 foot spacing for better support.  Tenax tubular posts are easy to install and the black color will be less visable than a wooden post. The heavy duty Tenax posts come in three parts the driving cap, the ground sleeve, and the post. Start by using the driving cap to drive the ground sleeve into the ground. The sleeve anchors the post and prevents it from being damaged during installation. The driving caps will mushroom over time so replace them as needed during installation.


Step 4 – Installing the fence

Unroll the Tenax fence along the posts securing it with 6 self locking ties per post. Hand tighten the fence at first as it is being unrolled to prevent mistakes.


If using more than one roll of fence use hog rings to secure any overlapping areas. Once the fence is secured to the posts use a hog ringer and rings to attach the fence to the top and bottom line of monofilament. A hog ring should be placed at least every three feet to properly secure the fence.

Lastly use ground stakes to secure the fence to the ground and prevent deer from digging under the fence. A ground stake or turf staple should be installed at least ever 5 feet. Hook the ground stakes or turf staples to the actual fence not the monofilament line and make sure they are pressed down fully into the soil.


Step 5 – Finishing touches

Every 10 feet attach a 12 inch long white ribbon along the fence at a height of 4 feet. This will allow the deer to see the fence at night and prevent them from crashing into it. Leave the ribbons up for a minimum of 6 to 8 weeks until the deer are aware of the fence and have adjusted their paths and grazing habits.

If rodents are also a problem black vinyl coated hex netting can be attached to the bottom of the fence. Add an additional 12 inches to the height of the hex netting required and fold the fence along the ground to create an apron along the grass to keep rodents from digging under the fence and onto your property. Use ground stakes to secure the apron portion of the fence to the ground and attach the hex netting to the poly deer fence with a hog ring every 3 feet along the fence line.


An effective deer fence doesn’t just keep deer out; it permanently alters their migration routes, so proper installation the first time is crucial. Once the deer learn getting onto your property or into your garden is more trouble than it’s worth they will look elsewhere.
