How to stop weeds in artificial grass

Stopping weeds in artificial grass
Jump to section

There are many reasons why people choose to install artificial grass in their yard. There is no need for mowing, fertilizing, or watering. Artificial turf is also very low maintenance and easy to clean.

One of the downsides of this type of lawn is that weeds can grow through it fairly easily.

If you have an infestation of weeds on your artificial turf, then you should consider using one of the weed killers below.

Why do weeds grow in artificial grass?

Artificial grass is a man made non organic surface so why are weeds growing there?

Weeds are successful because of their ability to reproduce and grow in varied conditions. Seeds are blow in on the wind or walked in on shoes and then sit waiting for the time to germinate.

If they have access to nutrients they will be able to grow roots and establish themselves. If weeds can grow on my PVC windowsill they can grow anywhere!

Weed killer

Weed killer is the number one solution for speed and ease. There are many options from weed killer sprays to granules or liquids.

The easier the product is for you, the better chance of success it will have in keeping your synthetic turf free of weeds.

What makes a good weed killer? Weed killers work by being either selective or non-selective making them more suitable for different types of weeds and different garden situations.

Selective weed killers are used in gardens where you want to keep the existing plants.

Non-selective weed killers are used when it is not important what gets killed, and this tends to be more damaging of other types of vegetation around them as well as synthetic turf.

One thing that all good weed killer should have is a long residual effect so that weeds will continue to be supressed for a long time after you have sprayed. weed killer

Contact weed killers are typically the simplest form of weed control to use. These types of weed killer work by preventing weeds from taking root and growing, so they need only be applied every few months between spring and fall for most lawns.

2.Systemic weed killer

Systemic weed killers work by being absorbed by the roots of weeds and gradually killing them. This type of weed killer is typically applied as a granular or liquid product to lawns, gardens, and other outdoor surfaces where you want to kill existing weeds before they grow up again.

A systemic herbicide will affect any plants that have contact with the chemicals and will work its way into their roots, eventually killing them.

Systemic weed killers can take longer to look like they are working than contact weed killers.

3.Residual weed killer

The most popular type of weed killer is a residual weed control product. These products are typically sprayed on the ground, and they remain active for months after application to prevent new weeds from growing. This long-lasting property makes them very effective at controlling both broadleaf and grassy weeds in lawns.

Residual weed killers are designed to hand around for a long time and can be poisonous to pets and other plants. It is generally not a good idea to use them on artificial grass which will be used frequent.

Spraying weed killer

Some weed killers come in a spray bottle. These are fine if you have just one or two weeds but for persistent problems, we recommend getting hold of a good quality sprayer that can be filled with an herbicide of your choice.

Weed sprays offer precision when spraying chemicals and the added benefit is being able to fill it with cheaper bulk-bought weed killer


Is using salt solutions to kill weeds in block paving just an old wives tale or can it be effective? Salt has been used throughout history as a low-cost way of keeping things from growing, and this is no less true today.

A high salt content can make earth unsuitable for both plants and pests alike.

How should salt be used

Salt is a natural weed killer. It will kill everything in its way so make sure you don’t let it seep into other areas or your garden because the salt may not wash away with rain over time and re-application of this solution needs to be done every six months!

How should salt be applied?

Salt is a highly effective weed killer, but has many drawbacks. It corrodes metal and concrete surfaces, leaves behind a residue that will need removing for safety reasons if you plan on planting anything close by or in this area again soon after application (or anyone who walks over it).

Sprinkling as grit results in more surface contact than spraying which may be desirable when using around delicate plants like tomatoes. 

A better method would be making your own saturated solution of water mixed with table-grade rock salt; then apply carefully from your garden hose onto target areas only!

Preventing weeds in artificial grass

The best cure for weeds is prevention. Thankfully there are a few quick things you can do every now and again to stop them from growing in the first place.

Brushing up

To get rid of pesky weeds, we recommend brushing your artificial lawn regularly with a stiff brush. This quick and easy task will keep your perfect looking lawn in pristine condition.

Make sure to use the synthetic bristles rather than metal ones when you are cleaning up as these won’t hurt grass blades or leave any grime behind.

Brush firmly towards pile direction for best results – this not only removes seeds but also helps keep turf upright so it always looks great!

Cleaning artificial grass and the whole garden can be a chore. See our top picks for power brooms, brushes and garden vacuums which take the effort out of the job.

Maintaining surrounding areas

For neat and weed-free lawns, regular maintenance of overhanging trees or hedges is a must.

Pruning tree branches will stop leaves from accumulating on your grass in the autumn; for quick clean up jobs use a leaf blower to remove any fallen foliage still lingering around when winter approaches!

Weed membrane

Weed membrane usually comes as part of the artificial grass however you should make sure its good quality or it may be ineffective in stopping and weeds coming through from underneath.

Seeds also settle on the surface of the turf and can grow through the membrane, so make sure to maintain a weed free surface and cover any exposed soil.

Sand and hardcore base

A properly installed base of compacted sand will starve the weeds of nutrients so even if they do start to grew it will be very difficult for the to become established.


Even artificial grass needs proper drainage or it could end up waterlogged.

A waterlogged lawn will be a great place for weeds and other living things to make their home.
