I found the best and easiest way to kill weeds growing in gravel was to use weed killers containing Glyphosate. they kill the whole plant including the roots. It kills annual and deep-rooted perennial garden weeds, including grass, docks, nettles, willow herb, dandelion and bindweed in one application with no need to reapply. A single two Litre bottle treats up to 3332 sq/m. If you are clearing just a small area store it in your shed for next season.

Weeding gravel by hand.
The only sure ways I know to keep gravel weed-free is to dig the weeds out by hand or to treat the area with Glyphosate weed killer. I have described both of the weed control methods I use in this article.
All that sounds great, except for one thing – weeds. Because there is more flexibility and movement with a gravel path, it can potentially see some unwanted growth, as weed seeds sprout from the ground into the gravel surface. In addition, grass can also potentially sprout from the gravel areas.
Weed the area thoroughly yourself
Some people take this a step further and use garden or landscape fabric instead of, or in addition to, the mulch. This step will indeed add time and effort to the job, but it also offers very good results as far as keeping the weeds away. You also have to make sure to have a method to have the material held down into the ground, so that it does not blow away. Then simply put the gravel on top of this level.
If elbow grease isn’t for you, then you can always look down the chemical route.

How to stop weeds in gravel. It’s a common sight seeing weeds in gravel driveways. If you’ve not laid a good, weed control fabric foundation or just don’t keep on top of removing those weeds that have planted themselves in the gravel, it’s not long before there’s more weeds than gravel in your drive way and the only way of getting to your car is by using a machete and dodging the man eating fly traps!
The final step is to lay a layer of decorative aggregate. You need a decent layer (3 to 5 inches) but not too deep as this can lead to puddle and weed growth.
4. Another layer of Landscape Fabric.
Using a compacted subbase (Granular base / hardcore base) will ensure the decorative aggregate is evenly distributed plus allowing for drainage eliminating puddles.
The chemical free / preventing weeds naturally.
Following these steps to prevent weed growth in gravel / gravel driveway is best achieved BEFORE you’ve laid any gravel. However, you can obviously move gravel out of the way and follow these steps (it’s just a little more tricky).
By laying a later of landscape fabric / weed control membrane it acts as a ground stabilizer so stone and soil do not mix.
3. Lay Sub Base.
Here’s a diagram:
For the small amount of weed that may appear from then on you’ll find they’re small and with a tiny bit of elbow grease can easily be pulled. Much easier to manage weeds if there are only a couple every few weeks rather than a field full.
Common gravel weeds range from grassy weeds to woody weeds. Broadleaf, henbit, purslane, chickweed, dandelions all find it fair gain when it comes to rearing their heads between the stone.
So, how to stop weeds from growing in gravel?
Well, the honest answer, you’ll never completely get rid of weeds existing in your drive. Weed seeds can travel through the air or via birds / insects. If there’s dirt, moister and sunshine then weeds will soon geminate.
However, there are precautions you can take to stop many of the weeds shooting up from the ground below. So keeping on top of keeping your gravel weed free is that little easier.
