3 Easy Steps to Kill Weeds in Rocks

1. Recognize the Different Weed Types in Your Rocks

Kill weeds in your rock beds in three easy steps.

You’ll find that most weed killers on the market attack a large variety of weeds. We advise that you, however, make sure you are purchasing the right one for your specific needs.

In some cases, weed applications will react differently depending on the weeds in your rocks; however, most weed killers for rocks will kill broadleaf weeds. These include dandelions and ragweed, and won’t harm your grass.

It’s essential to note what is around your weeds besides rocks. If there are flowers, shrubs, grass, etc. nearby, you’ll want to use a weed killer that is selective and only kills weeds. Some weed killers can destroy anything it comes into contact with, including grass and flowers. Make sure to read the manufacturer’s recommendations at all times.


2. Apply a Liquid Weed Killer Application to Kill the Weeds in Rocks

After identifying what weeds you’ll be killing and what non-weed greenery surrounds thems, you’ll need to use a liquid chemical herbicide on the weeds. So, why should you choose a liquid treatment over a granule application?

Killing weeds in rocks helps to create a beautiful and healthy rock landscape bed.

We believe that liquid spray is much more effective on weeds in rocks than granules. The reason for a liquid treatment is the opportunity to spot treat and to assure the weed killer is absorbed in the root system. Unlike granules, liquids can tackle the exact places you want to treat.

Keep in mind that when you are utilizing liquid weed killers, they typically need to be mixed with water due to their concentrated formula. Be sure to read the manufacturer’s recommendations at all times.

We recommend that you select your weed killer carefully and choose one that is perfect for your particular weed type. Keep in mind that most liquid weed killer applications are designed to kill a specific kind or small range of weeds. Some weed killers can kill plants, flowers, and shrubs.


3. Make Sure Weed Roots Are Saturated and Clean Up

After you’ve made note of the weeds in your rocks, applied the appropriate weed killer, you can pull the weeds or allow them to die naturally. Either way, make sure to allow enough time to pass so the liquid weed killer gets into the root system.

Weed Killer Warning! Always read the manufacturer’s recommendations when choosing and applying any chemical herbicides to your lawn or landscape beds. Wear protective gloves and remember that some weed killer applications can kill flowers, grasses, and shrubs.

FAQs About Killing Weeds in Rocks

How do you apply weed killer applications in rocks?

When applying weed killer in rocks, you should spray on a sunny day when there is no rainfall expected and not a lot of wind. For effective results, spray in the spring season, late summer, early autumn. We recommend checking the weather forecast to assure there is no rain for the next six hours after application.

There are, however, some weed killer concentrated products that are rainproof. Consider those according to your needs. It’s also important to keep in mind that you should spray weeds before they grow out to make it easier to control them.

It’s important to choose effective weeding tools to remove the weed root.

To apply properly, you should apply the solution with a sprayer thoroughly over the targeted spaces. This will make the solution penetrates the plant entirely into the root system.

How do you keep weeds from growing in rocks organically?

The simplest option to prevent weed growth organically is to pour boiling water on the weeds. This process will burn the leaves of the weeds and kill them immediately. If you add vinegar in the boiling water, it offers amplified results. Salt is another excellent substitute for harsh herbicides, but they should not be used in a rock garden because it can change soil salinity.

How do you kill weed permanently in rocks?

There are many weed killers available to prevent weeds from growing back. But keep in mind that these herbicides will only kill weeds for certain durations. Be sure to read the manufacturers recommendations. If you want to kills weeds permanently, you may want to consider a salt application that will adjust the salinity in the soil. You will need to mix one cup of salt in two cups of water and boil it. Then, pour this mixture directly on the weeds to kill them permanently.

Will bleach kill weeds in rocks?

Yes, bleach will kill weeds in rock, but there are some things you need to be aware of before using it.

All you need to do is spray undiluted bleach on the weeds in your walkway, driveway, or rock bed and then let stand to kill them. The solution will kill existing weeds and help prevent new ones from sprouting. 

Please note that bleach will kill grass, flowers, and other vegetation as well, so be careful. Also, bleach is NOT suitable for the environment and thus not recommended.

How do you prevent weeds from growing in existing landscaping rock?

If your landscape rocks are already in place, you can help prevent new weeds from growing by treating and discarding existing weeds before they can drop seeds. If you pull weeds, make sure you get the root (wet them down first – it will make the job much easier).

Some landscapers swear by periodically sprinkling salt over the area. Just pply the salt liberally and spray the area down with water. You can also use a preemergent weed killer, as long as you apply it carefully, in accordance with the manufacturer’s instructions.

How do you prevent weeds from growing in new landscaping rock?

If you are preparing to put down landscaping rock, do yourself a favor and prepare the area appropriately.

If you are so inclined, use a good preemergent according to the product’s instructions. Next, install a steel edging border that is at least 3 inches high (4” is better). This will prevent weeds, grasses and plants from sending roots into your rock beds.

Killing weeds in rocks is easy with the right weed killer application.

Now, put down a layer of underlayment. The heavy black plastic you may have seen in the past is not ideal. It decomposes quickly and corners start to stick up through the rock. Instead, top your bed with a good landscaping fabric. We highly recommend Hanes weed barrier fabric because, in our experience, it is the most weed-resistant.

If you want to add a layer to block the sun (sunlight encourages weed growth), add a thick layer of newspaper or cardboard over the fabric.
