Quick answer

How to stop garden weeds: pull them with the roots after rain, smother the bare soil with cardboard and 2 to 3 inches of mulch, and keep at it for a few weeks. In beds you will not dig again, such as shrub borders and paths, woven landscape fabric under the mulch blocks the light that new seedlings need, so the weeds stop coming back every week.

Free fix vs. permanent fix

Free fix · 1 to 2 hours

Weed, cardboard and mulch

  • Pull weeds after rain so the roots come out
  • Lay flat cardboard over bare soil
  • Cover it with 2 to 3 inches of mulch
  • Top up thin spots each spring

How long it lasts: One season. Mulch breaks down and thins out, and new seeds blow in on top.

Most readers choose Permanent fix

Woven landscape fabric under mulch

Fabric stops the light that buried seeds need and blocks most weeds from pushing up from below. The free steps clear today's weeds, and the fabric stops the next round. It works best in beds you do not dig or replant.

What to get: Woven landscape fabric roll

How long it lasts: Several years in shrub beds and paths, as long as the mulch on top stays 2 to 3 inches deep.

Why it happens

1

Seeds already in the soil

Garden soil holds a bank of dormant weed seeds. Digging or raking brings them up to the light, and they sprout within days.

2

Roots left behind

Dandelions and dock regrow from a piece of taproot. Bindweed and nutsedge spread from roots and tubers. Snapping off the top only resets the clock.

3

Bare soil

Open soil gets light and moisture, and wind and birds drop in more seeds. Weeds fill any gap you leave.

4

Mulch that is too thin

Mulch under about 2 inches lets light through. Over time it also breaks down into soil, and weeds root in that.

Do these in order, starting with the simplest.

  1. Pull weeds after rain

    Tool used: Hand weeder or weeding knife

    Wet soil lets roots slide out whole. Grip low at the base and pull straight up. Use a weeder for dandelions and other deep roots, and bag any weeds with seed heads instead of composting them.

  2. Stop digging the bed

    Do not till or rake the soil afterward. Turning it lifts buried seeds into the light, so leave the surface undisturbed.

  3. Smother bare soil with cardboard

    Tool used: Plain cardboard

    Lay overlapping sheets of plain cardboard over the cleared soil and wet them down. The cardboard blocks light and rots away over a season.

  4. Lay fabric in beds you will not replant

    Tool used: Woven landscape fabric

    Roll woven landscape fabric over cleared shrub beds and paths. Overlap seams by 6 inches, pin the edges and seams about every foot, and cut an X for each plant. Fold the flaps down around the stem.

  5. Cover it with 2 to 3 inches of mulch

    Fabric left bare breaks down in the sun. Cover it with bark, wood chips or gravel, and keep mulch off plant stems. Pull any seedling that sprouts in the mulch while it is small.

When free fixes aren't enough

If you pull the same bed every week even with mulch down, the soil is feeding a heavy seed bank or perennial roots keep coming back. Mulch alone thins out, and you end up topping it up every season. Fabric is the fix for beds you plant once and leave: shrubs, hedges, tree rings and gravel paths. It will not stop weeds that root in old mulch on top of it, and it will not stop bindweed or nutsedge, so dig those out first. Skip it in vegetable and flower beds you replant or fill densely.

Woven landscape fabric roll

Fixes: weeds sprouting from seeds in the soil below

Look for: Woven and permeable, so water and air pass through; UV-stabilized for sun exposure at the edges; A roll wide and long enough for the bed, with room for overlap; Strong enough not to tear when you cut plant holes.

Who it's for
Anyone with shrub borders, tree rings or paths they do not want to weed all summer.
Honest downside
You replant or dig the bed every year, as in a vegetable garden, or the bed is full of bindweed that you have not dug out.

Heavy-duty woven ground cover for gravel paths

Fixes: weeds pushing up through gravel paths and under stone

Look for: A heavier weight sold for use under gravel or stone; Permeable weave with a UV note on the label; Roll widths that fit a path with minimal seams.

Who it's for
People laying a gravel path, a patio base or a bed under heavy stone.
Honest downside
Your bed is small and mulched. Standard fabric under mulch is plenty.

How we picked: How we picked: this page is based on university extension advice on mulching and weed control, installation guides from landscape fabric makers, and what owners report in reviews. We do not test products by hand.

How much to buy and how to lay it

  • Measure the bed's length and width, then add 6 inches for each seam where sheets overlap.
  • Clear the bed first. Pull weeds, remove rocks and rake it smooth, but do not dig deep.
  • Pin the edges and seams about every foot.
  • Cut an X for each plant, fold the flaps down and mulch right away.

What to skip

Solid black plastic sheeting

Plastic sheeting blocks weeds, but it also blocks water and air. Roots under it stay shallow, and rain runs off to the edges. If you want a barrier, choose a woven, permeable fabric instead.

Frequently asked questions

Does landscape fabric work in a vegetable garden?
Not well. You dig, plant and pull crops every year, and the fabric gets in the way. Use cardboard and mulch between rows instead, and pull weeds early.
Should landscape fabric go under or over mulch?
Under. Lay it on cleared soil, then cover it with mulch or gravel. Fabric left bare breaks down in the sun and looks messy.
Why are weeds growing through my landscape fabric?
Usually they are rooting in the mulch on top, where leaves and dust have broken down into soil. Pull them while small and add fresh mulch. Perennial weeds such as bindweed can also push up from below, so dig them out before you lay fabric.
How long does landscape fabric last?
A woven, UV-stabilized fabric under mulch often lasts several years. Thin cheap fabric tears sooner, and fabric left bare in full sun breaks down fast. Keep it covered.
