How to lay weed membrane on a bed or a garden path

Updated: October 2026

The sheet is in the hall, the bed is still full of couch, and you want the bark on before the rain. How to lay weed membrane is a sequence: clear perennial roots and sharp stones, overlap by the figure that matches the job, peg the edges, cut small slits, and cover the cloth before you stop. This page is that order for a bed or a footpath, not a product ranking and not a driveway. Sizes are on the [weed membrane comparison](/hub/weed-control/weed-membrane-150g), from listings read on 16 October 2026. The Products Compared editorial team did not lay a trial bed.

Clear the ground first

A membrane shades seed only after you cover it. It does not kill a root that is already underneath. Dig out bindweed, horsetail, couch grass, nettles, and brambles before the sheet goes down. If you lay over a live crown, the shoot comes up at a peg hole. Take out stones that would punch the sheet. On a path, a proud stone becomes a hole the first time you wheel a barrow across it. If the infestation is beyond hand digging, stop and get a gardener in, rather than pinning a sheet over a bed you already know will erupt.

Overlap, and why the number changes

UK guides do not agree on one overlap. GravelMaster says at least 100 mm where the aim is weeds, and 300 mm where the aim is ground stabilisation. Suregreen says at least 6 inches, about 150 mm. DuPont's Plantex page says at least 10 cm, and that page is written for a non-woven. Use the larger figure on a path or a slope. Use about 100–150 mm on a flat mulched bed. A 1 m roll on a 2 m bed means a seam. A 2 m sheet, such as Velway or a GardenGloss fold, can cover that bed in one width. The buying checks are on the 150 gsm weed membrane buying guide. Folded packs need to be opened fully before you cut. If you cut the parcel as it arrived, you cut several layers. Which size you should have ordered is on the best 150 gsm weed membrane page.

Pegs and planting slits

Peg the edges and the overlaps before you walk away. Ten pegs will not hold 30 m² in wind. YOUNTHYE includes 10 pins with a 3 m × 10 m sheet. Velway includes 30 U-pegs, stated as 150 mm × 36 mm and 3 mm wire, with only 10 m², and UK reviews say that wire bent in compacted soil. The other listings are the sheet alone. If the first peg folds, the ground is too hard for that wire. For a plant you are keeping, cut an X, tuck the flaps under, and plant through the gap. A cross, not a circle the size of a plate. Velway and iropro reviews describe fraying at a cut, and Vivo reviews say edges go hairy if you leave them uncovered.

Cover it before you leave it

Bark or stone keeps light off the cloth and the sun off the plastic. DuPont says at least 5 cm of mulch on its Plantex page. Suregreen says about 5 cm of mulch or about 4 cm of aggregate, and cover within 24 hours. For these sheets, cover the same day. A bare woven edge left until the weekend is how cuts fray. GardenGloss says its UV stabilisers do not mean prolonged direct sunlight, and iropro gives no years for its sunlight line. Call a fitter when the surface will carry a car, when the ground floods, or when water would run onto the highway.

Common questions

What do I remove before the sheet goes down?
Take out bindweed, horsetail, couch, nettles, and brambles, plus sharp stones and stubs. A sheet laid over a live perennial root does not finish that plant. It gives the shoot a peg hole to use. Strim the top growth if you must, then dig the crowns you can see. If the bed is solid with those roots, get help rather than pinning over them.
How much should the sheets overlap?
Use about 100–150 mm on a flat bed where the job is shade under mulch. Use a wider overlap, towards 300 mm, when a guide is talking about stabilisation or when the join is on a slope or under foot traffic. GravelMaster, Suregreen, and Hy-Tex do not publish one shared number. Do not treat 100 mm as enough for every path.
How many pegs, if the box has 10 or 30 or none?
Velway's 30 pegs belong to 10 m², and some of that wire bends in hard ground. YOUNTHYE's 10 pins belong to 30 m², which will not hold the sheet in wind. Every other listing here is the fabric only. Peg edges and overlaps before you leave the garden. If the first peg bends, change the pin rather than forcing the rest of a thin bag.
How do I cut for a plant without a huge hole?
Cut an X, fold the flaps under the sheet, and set the plant in the cross. A round hole the width of the pot is a gap for weeds and for light. Woven cloth frays at the cut, which UK reviews on Velway, iropro, and Vivo describe. Keep the slit small and cover the surrounding sheet the same day so the cut edge is not left bare.
Do I cover it the same day?
Yes. Bark or stone is what blocks the light and protects the plastic. Suregreen's own FAQ says cover within 24 hours. Other makers say cover and do not all use that clock. Leaving a woven edge in the sun for a week is how reviews end up describing hairy, frayed tape. A UV line on the listing is not a substitute for the mulch.
Will it stop horsetail or bindweed if I lay it on top?
No. Those plants are already under the sheet, and they come through joins and slits. Dig them out first. The membrane is for shade under a cover, so seed on the surface has less light. It is not a cure you unroll onto a bed of live couch. If you cannot clear the roots, do not expect the plastic to do that digging for you.
