Best weed killer for gravel driveways (get rid of weed completely)

Gravel driveways are a nice addition to your home, and generally speaking, they are much cheaper than alternatives such as block paving.

However, if neglected, gravel pathways can become a real pain as they can become overgrown with weeds and grass.

There are various ways to eliminate weeds in a small patch, but a designated weed killer will be better if they are persistent.

In our considerations, Roundup Ready-To-Use Weed Killer is the best of them all due to its fantastic formulas and quick, visible results.

What we like

This weed killer employs a dual-action formula that kills existing weeds and prevents new ones from growing for months afterward.

Our first weed killer pick captures us as it can turn rainproof in a matter of 10 minutes and you will see visible results in 3 hours. You can use it on other areas besides the gravel paths, such as the patio, curb, the fence, and parts of the lawns.

What can be improved?

This product is not without its fault, however. The weed killer can be too potent, thus causes an unpleasant smell that poses a health risk if too often exposed.

Buying Guide for the Best Weed Killer for Gravel Driveways


Even the best weed killer for driveways can only kill certain types of plants instead of all of them; thus, it is advisable to research the weeds growing on your gravel driveways before deciding on a purchase.

Selective weed killers are effective on broadleaf weeds, such as clover, creeping charlie, or dandelions. Unwanted grasses like crabgrass can also be quite susceptible to weed killers.

Non-selective weed killers will kill everything in sight once you apply them to your gravel driveways, giving you full weed control – highly recommended for this purpose.

Homeowners usually don’t want anything left growing on their gravel areas for a cleaner look, unlike lawns, where the presence of grass is nice and welcoming. That’s why you must check first whether the weed killers are selective or not.


Persistent weed killers will kill grasses and many types of weeds effectively. The effectiveness is easily seen: once applied to an area, besides the initial effects, usually minutes after application, there will be residues that linger and continue to prevent unwanted grasses from reappearing.

In this regard, liquid rather than granular weed killer are better as some of them will protect an area for a long time, even up to a year. But don’t expect every weed killer to be like this, as this long-term, powerful performance is rather exclusive.

However, if possible, try to find the most persistent yet natural weed killers out there to accompany your household maintenance. They will kill even the toughest weeds without relying on extra toxic chemicals.

Pre-Emergent or Post-Emergent

The first method is possibly more common, which is killing weeds after they’ve already grown. Grown weeds are visible, hence easier to counter.

For that reason, if you have weed roots already growing in your paths, consider a post-emergent weed killer. They will be effective in helping you gain back control over unwanted weeds.

However, if you despise seeing even a sight of weeds in gravel or any weed growth, consider a pre-emergent weed killer. It’s used as a preventative measure to make sure that weed won’t grow in the first place.

The effectiveness is enhanced when you combine both of these techniques. If your gravel areas already have stubborn weeds, after you’ve applied the post-emergent weed killer, spray the pre-emergent weed killer to prevent them from growing back.

Get to know more about when to apply pre-emergent weed killer to your lawn:

Contact or Systemic

Contact weed killers will act only upon the plant’s parts being sprayed, meaning that so long as the plant is sprayed correctly, it will be killed.

But the effectiveness of said weed killers leaves a lot to be desired, for they won’t kill the roots. The weed killers won’t be as effective beneath the soil, allowing the weeds to grow back again.

In contrast, systemic weed killers will attack the plants from the inside, kill them entirely, even the roots. They are absorbed through the leaves, so it might take some time for you to notice the results.

Systemic weed killers are for patient customers, but the outcome is worthwhile as once a plant is killed, it won’t grow back. With enough application, your gravel driveways are sure free of weeds for a long period.


Safety is quite an underrated feature, but important nonetheless. If you are using a weed killer for your gravel pathways, make sure that you wear protective gear and avoid being exposed to toxic chemicals that might pose serious health complications.

Look for components, such as backpacks, nozzles, and more, so that you will only have minimal exposure when spraying the weed killers. Some types of weed killers are more eco-safe, especially for people and pets, while still being effective.


Your weed killers’ size is very important, as this will determine how effective it is for your gravel areas. It is better to assess firsthand how big the weeds and the weed-covered areas are, then go over the size of the weed killer you intend to buy.

If you have a wide and long gravel path but only minimal weed growth, you probably don’t need too big of a weed killer. However, if you have a small gravel area but infested with unwanted grass, a large-sized weed killer might be what you need to help with removing weeds from gravel.


There’s a balance in ensuring the safety of your family, yourself, and your pets. The potency of the chemicals required to kill weed growth effectively will determine how fast and thorough the weed killer will be in their effects, but they might also pose a health risk if used frequently.

Industrial weed killers are usually deemed as the best and most effective weed killer for gravel, but more and more people these days are opting for a more organic alternative instead.

Rock salt, table salt oriented, or pure vinegar-based weed killers are almost just as effective as the industrial weed killers, but usually, they will require your patience and effort spent on applying them.


In our consideration, Roundup Ready-To-Use B001OELY9C Weed Killer is our choice as the definitive best weed killer for gravel.

However, for this list, there are no wrong choices. We’ve included a buying guide with detailed reviews to help you determine which is the best and most suitable weed killer for you.

Have a nice time revamping your gravel driveways, and remember to wear protective gear!
