The string trimmer dance, every week
- Weed-eating along every post and under the bottom rail after each mow
- Herbicide sprays near the spots where kids and pets play
- Ragged, uneven edges that grow back in days
A barrier that sits where the grass grows
- Flat guards lie under the fence line and are designed to block sunlight and growth
- Interlocking dimples snap units together into one continuous strip
- A notch fits around each post, and teeth on the underside grip the soil
How it works
Designed to install in three steps, no tools.
Lay it along the fence
Set a Fence Fender under the fence line, with the notch around a post or gate pole.
Snap the next one on
Overlap the next unit and press the dimples together to keep the strip continuous.
Press it into the soil
Step or press down so the cone-shaped teeth grip the ground and hold it in place while you mow.

What makes Fence Fenders different?
Interlocking dimple system
Units are designed to overlap and snap together, so the barrier extends to fit any length of fence.
Universal notch
A cutout notch fits around fence posts and gate poles, so there's nothing to cut or modify.
Ground-grip teeth
Cone-shaped teeth on the underside grip the soil to keep each unit from shifting while you mow.
No herbicides needed
A physical barrier against grass and weeds, with no herbicides near pets and kids.

Lawn care without the tedious trimming
Fence Fenders was born from a frustration with overgrown grass under fences and the wish to stop spraying weed killer. We design smarter landscaping gear for homeowners who take pride in their yards but value their time. Our first product uses a simple interlocking system to create a seamless barrier against unwanted growth, and it's in development now.
What we build for
Simple installation
No tools, no digging, no cutting.
Fewer sprays
A physical barrier instead of herbicides.
Stability and durability
Designed to stay put through mowing and weather.
