DuPont Plantex ®

Landscape fabric

Frequently asked questions


DuPont™ Plantex® works by suppressing weeds. When combined with a mulch covering or under paving, light cannot penetrate to the weeds. The unique structure of DuPont™ Plantex® gives it immense strength. Weeds already weak from lack of light cannot penetrate through the fabric. However, unlike black polythene, DuPont™ Plantex® will allow the soil to breathe and lets water through.

Which way up do I lay DuPont™ Plantex®?
Any way. DuPont™ Plantex® can even be laid vertically to stop weeds penetrating from next door.

Can I feed my plants through DuPont™ Plantex®?
Yes. Liquid feed will pass straight through.
The nutrients in solid feed will also leach through over a short time, therefore providing a more controlled feed.

Can I lay DuPont™ Plantex® around existing beds?
Yes. Although slightly more fiddly than a new bed, DuPont™ Plantex® can be cut around the base of your plants. Remember to allow a 100mm overlap.

How long will DuPont™ Plantex® last?
When covered with the correct depth of mulch, DuPont™ Plantex® will last for over 25 years. If used uncovered or with insufficient cover the ultra violet rays in sunlight will weaken the tensile strength of DuPont™ Plantex®.

Can I walk on DuPont™ Plantex®?
Yes. DuPont™ Plantex® is used under footpaths in many public parks. It is also used under golf bunkers and turfed sports surfaces.

Will DuPont™ Plantex® harm children or pets?
No. It is chemically inert. It can even be used to line pond plant baskets and as a filter layer in fish tanks.



Will DuPont™ Plantex® stop all weeds?
There are a few weeds that need special attention. With sharp pointed grasses like couch it is advisable to double the amount of mulch cover (e.g. bark use 100mm). If you wish, you can spray the area first with a glyphosate-based weed killer. Ground creeping weeds like bindweed and ground elder will not penetrate DuPont™ Plantex®. However, where you have ground creeping weeds make sure the edges of the DuPont™ Plantex® are buried at least 100mm into the ground around the edge of the bed.

One weed we all fear is Mare's tail. For this we recommend a hand full of lime placed around the infected area, then use two layers of DuPont™ Plantex® topped up with a double thickness of mulch. We have had an 85% success rate with this weed, but no guarantees!
