3 Powerful Weed Killers That Actually Work On Gravel Driveways & Paths

Removing weeds from your driveway can be quite the task. While it may be tough to get into the nooks and crannies of your drive, there are many weed killers that can do just that — and fast. The best weed killers for gravel pathways will largely depend on how persistent and resilient the weeds are, and whether you want to use chemicals.

If the weeds are in a small patch or seem to be growing slowly, you can probably go with a mild or even a chemical-free herbicide. On the other hand, if the weeds just keep coming back (and back, and back) then it may be best to go straight for the big guns: a glyphosate-based weed and grass killer that banishes every unwanted growth down to the root. If you are dealing with truly persistent weeds, consider investing in a more expensive weed killer that also works as a preventative treatment to keep weeds away for longer.

To get the job done quickly and efficiently, it's important to find the best weed killer for your property. Here's a round-up of some of the the most effective options out there to help you tackle any and every weed.
