How to Get Rid of Weeds in Gravel, Pavers & Patios

Weeds in gravel, block paving, and patio cracks need a different approach than lawn weeds. Here are the tools and methods that remove them for good.

Weeds poking through gravel, patio cracks, and block paving are a different problem from lawn weeds — and a claw-style weed puller tool isn’t the right fit for them. Here’s what actually works on hardscape.

Why pavers and gravel are different

In a lawn or bed you can get a tool around a weed and lever the root out. In a paver joint or gravel path, the weed is wedged into a narrow crack with stone or sand packed around it. You need tools that fit into the gap and scrape or dig the weed out — not claws that need open soil.

Tools that actually work

Block-paving / crack weed knives — an L-shaped or hooked blade that drags along the joint, digging weeds and moss out of the gap. The single most useful tool for paving.
Long-handle crack weeders — the same idea on a stand-up shaft, so you can scrape joints without bending.
Wire brushes / weeding brooms — a stiff wire brush (handheld or on a long handle) scrubs weeds, moss, and debris out of cracks fast.
Weeding torches — a propane flame wand that wilts weeds in gravel and cracks without chemicals. Use carefully and never near anything flammable.
Boiling water — the cheapest option: pour it straight onto weeds in cracks to kill them, roots and all, over a day or two.

Step by step: clearing weeds from cracks

Loosen the weed by dragging a crack knife or wire brush along the joint.
Pull what lifts out, getting as much root as you can.
Treat the rest — scrape the remaining roots out, or wilt them with boiling water or a weeding torch.
Sweep the joint clean of debris and old soil.

Preventing weeds in gravel and pavers

The real win is stopping them coming back:

Re-sand paver joints with polymeric sand, which hardens to seal the gaps.
Lay a weed membrane under new gravel to block weeds from below.
Sweep and clear regularly — weeds need trapped soil and debris to root in.

What about a stand-up weed puller?

A stand-up weed puller is the wrong tool for cracks — its claws need open soil. But it’s the right tool the moment those weeds spread into the lawn or beds beside your patio, so it’s still worth owning. See our best weed puller tools guide.

The bottom line

For pavers and gravel, skip the claw puller and reach for a crack knife, wire brush, or a chemical-free wilting method — then seal the joints so the weeds don’t return.
