Factors to Consider When Choosing the Best Weed Killer for Gravel

Sand and gravel can both be treated with the same weed-killing chemicals that are used on lawns, around fence lines, and in cracks in sidewalks.

But when it comes to gravel, it’s especially crucial to eliminate these invasive weeds early on as they will multiply rapidly and even a few clusters will destroy the aesthetic appeal of your outdoor gravel space.

Dead weed clusters can be concealed under shrubs and bushes around the garden area. You can learn more about the best weed killer for Bermuda grass here. However, it is different for gravel pathways and driveways.

Gravel has a wide range of weed issues, from a single dandelion that grows in the middle of a route to invasive crabgrasses that gradually erode the gravel pathway edges. 

However, before you buy a weed killer for gravel, you must take into account the following factors.

Selective Weed Killers Vs. Non Selective Herbicide for Gravel Driveway

There are two types of chemical ingredients that are used in weed killers: selective and non-selective.

Many herbicides are selective, meaning they only kill some types of weeds while leaving other types unharmed. Depending on the product, selective herbicides destroy different kinds of weeds. To improve the quantity and variety of weeds eliminated, a number of selective herbicides may be combined.

Any plant will be killed with a non-selective weed killer. It eliminates both undesirable and desirable plants if you aren’t careful. All precautions should be taken to prevent interaction between desired grass or plants and overspray when using non selective weed killers on gravel driveways and walks.

The Right Ingredients for Gravel Weed Killers

The best weed killers contain one or more chemical herbicides that are well-known for their capacity to destroy vegetation. To help the herbicide adhere to the leaves of the undesirable plants, a number of chemicals are utilized, some of which kill weeds and others of which serve as surfactants or mixing agents. The following are some of the most typical components in weed killers:


Some weed-killing products contain the chemical triclopyr. This herbicide is non selective. It is one of the finest options for usage on gravel walkways next to lawns because it won’t affect most varieties of turfgrass. But, it will kill a variety of weeds, including invasive species like mesquite and locust.


Some non-selective herbicides contain glyphosate as an active component. However, due to grave worries about its influence on the environment and potential connections to cancer, it is gradually being taken out of production in the United States. Unfortunately, glyphosate is still widely used today because of how well it kills all vegetation.


This is another targeted herbicide that kills invasive broadleaf weeds. It can also be used in conjunction with triclopyr to destroy weeds more effectively. It is safe to use close to lawns, just like triclopyr.

Duration of Effective Weed Killers

The persistence or lingering effect of a herbicide is determined by how long it takes to finish killing weeds after application. It also depends on whether it degrades upon contact with water. 

In other words, this relates to how long the weed killer will remain effective after a single application. It also counts when you will need to reapply to avoid weeds to regrow.

For gravel and sand, a weed killer that lasts on a path or driveway for a few months is ideal. Short-term weed killers will get rid of current weeds, but they don’t have a lasting effect, so you might need to treat your lawn more frequently.

Contact vs. Systemic Weed Grass Killer for Gravel

Non selective herbicides can be one of the following two types: contact or systemic weed killers.

Firstly, contact weed killers kill any form of green foliage as soon as it comes into contact with it. Spraying contact herbicides evenly and covering as much of the green sections of the weeds as possible will produce the best effects. The immediate death and browning of the leaves causes a shock to the weed root system, ultimately killing the entire plant.

On the other hand, a systemic herbicide seeps through the plant’s foliage and reaches the root ball, killing it entirely. These are extremely potent and should be handled with extreme care. It is better to spray them directly on the plant foliage. You can read about the best weed sprayers for this purpose. Overusing these chemicals can cause them to seep into neighboring plant roots, killing other desirable plants as well.

FAQs for the Best Weed Killers for Gravel Driveways

Yes, spraying weed killer on gravel can damage the garden soil. This can happen if your garden is located right next to the gravel driveway or path.

Overspraying any form of non selective herbicide can cause desirable plants to die and damage the garden soil quality. Keep in mind that some weed killers may also leave behind residual traces that can keep new plants from growing there.

You can permanently get rid of weed grass in your gravel driveway by paving over the gravel with concrete. 

If that is simply not an option for you, try a potent weed killer to eliminate existing weeds and discourage new weeds to sprout in the near future. You can then use a pre emergent over the gravel surface to keep invasive weeds from returning.

No, it is not safe to use organic weed killers for gravel around dogs. Digestion of any concentrated herbicide can cause a reaction or health complications in your dogs. 

Therefore, it is never safe to use any form or weed killer, be it organic or synthetic, around dogs.

No, natural weed killers do not eliminate weeds on gravel quicker than chemical weed killers. This is because chemical herbicides are packed with potent combinations of 2-4-D, glyphosate, etc. 

Each of these creates a lethal blend that can instantly result in invasive weed killing. Organic herbicides are milder in comparison as they lack the harsh chemicals.

Bottom Line on the Top Weed Killer for Home Gravel Driveways and Paths

Our top recommendation for the top weed killer for your home gravel driveways and paths is undoubtedly the Ortho GroundClear Year Long Vegetation Killer thanks to its instant and long lasting results. It also prevents weed growth in the future.
