Grass Barrier · Along a fence

How do I keep grass from spreading under a fence?

Set Grass Barrier on edge in a trench along the fence. The standard layout puts 6 in below the soil and 4 in above, so runners have to climb the lip, where you can see and trim them.

Under-fence questions

Will Grass Barrier stop every weed along a fence?

No. It helps keep grass that spreads by runners and rhizomes from crossing the line. Seeds that land near the fence still sprout, so plan to weed and trim along it.

Which way does the 10 in run?

Up and down. Grass Barrier is 10 in tall, top to bottom. In the standard layout, 6 in goes below the soil and 4 in stays above.

Can I trench beside fence posts?

Yes. Call 811 before you dig. Mark the posts, their footings and irrigation too, and keep the trench clear of all of them.

What goes in my cart?

One cut of Grass Barrier at the length you chose: 10 in tall, 100 mil HDPE, in one continuous piece up to 110 ft. Each cut is its own cart line.
