Artificial grass is controversial. Once seen as a tempting alternative to keep your garden looking great all year round, it's since been engulfed by concerns about its environmental impact. There are even calls for it to be banned altogether. Plastic Green Wall

Best Artificial Grass 2024: Realistic and Good Quality Artificial Grass - Which?

Nevertheless, there may be circumstances where it might be a pragmatic choice. For instance, if you want to create a children's play area in a shaded north-facing garden where real grass won't grow. 

If you do decide that artificial grass is your only option, there are things you can do to mitigate the environmental impact (see below). 

Bear in mind, too, that even many current owners of artificial grass regret their decision. According to a recent survey by the insurance firm Churchill, nearly three in five respondents (58%) said they wanted to remove their artificial grass, and almost half (44%) said they were concerned about the environmental consequences.

Overall, yes. Although most products have some kind of environmental impact, there are good reasons why artificial grass is particularly bad.

The damage begins beneath the surface: most worms and soil insects that thrive under a real lawn can't survive under a synthetic one. This displacement disrupts the soil ecology, leading to unknown long-term effects. Above the surface, an artificial lawn can't provide the necessary nutrients to sustain birds and other garden wildlife, including bees. 

Artificial grass is often made of virgin plastic and lasts 10-15 years. Not only does its manufacture require significant energy and resources, but when it's time to replace it, the plastic often can't be recycled. This means that most is destined for landfill or incineration. Synthetic grass also brings the potential hazard of loose fibres, adding to microplastic pollution.

Finally, while real grass plays a role in mitigating climate change by converting carbon dioxide into oxygen, artificial grass simply can't do this.

If artificial grass is your only viable choice, there are some ways to alleviate its environmental impact. 

For a start, consider limiting the area you intend to cover with artificial grass. If you're creating a play area, for instance, leave a border of natural soil around the edge. This will provide a habitat for soil-dwelling creatures and help maintain the local ecology.

You can also grow insect-friendly flowers in pots or in the remaining soil around your artificial turf. Not only will this add colour and vibrancy to your garden, but it will also offer much-needed nourishment for bees and other crucial pollinators.

A growing number of artificial-grass manufacturers now offer schemes to take back old synthetic turf for repurposing or proper disposal. By choosing one of these companies, you'll help encourage the industry at large to develop better recycling processes for old artificial grass.

Fake turf is expensive compared with real turf (which typically costs around £6 per square metre). Artificial grass can cost anything from £15 per square metre – on a par with carpet. Premium-quality artificial grass, designed to look and feel like the real thing, can cost as much as £60 per square metre. Most artificial grasses come in rolls that are 2 or 4 metres wide. 

But remember, the grass is only part of the equation. You also need to consider the cost of installation, which typically involves preparing the ground, laying a weed membrane, spreading and compacting a sub-base of sand or other material, and finally, laying the artificial grass. You could try laying it yourself, but if you want a level lawn and a good finish, it’s probably best to employ a local landscaper or an artificial lawn specialist to fit it for you. 

Many manufacturers will offer to fit the grass for you, and prices vary depending on the complexity of your garden. The prices quoted for fitting a 50sq m area range from £2,650 upwards. Be sure to do your research and take advantage of any price-match offered by various professionals to keep the costs down.  

Keep your real grass looking fresh with our best lawn treatments

In 2021, we tested 13 types of mid-priced artificial grass to see which looked the most natural, even after it had been subjected to some tough wear and tear. The highest rated artificial grass we found looks from a distance like the real thing, but low-scoring options are let down by weak backing material that struggles to keep the grass secure.

Because of the environmental implications and sustainability concerns associated with artificial grass, we don't have any Best Buys and have no plans to test any more artificial grass products.

There are three materials used in the production of artificial grass, each with their pros and cons.

Artificial grass made with nylon is better protected against the elements than polypropylene grass. Nylon is a particularly strong type of plastic fibre, so if you're looking for an artificial lawn that can withstand children and pets, consider nylon grass.

This is a good option if you want to keep costs down. Polyethylene artificial turf has a natural look and a texture that's soft to the touch, like real grass. You obviously won't be running a lawn mower over it, but remember to brush or rake it occasionally.

Although polypropylene grass will usually be your cheapest option, it's also the least durable type. As a result, it's best to use this grass in small spots rather than for large lawns.

Most of us think of artificial grass as being a fake-looking dark green. But a range of tones are available, and many include strands of brown fibre and 'grass blades' of varying heights to simulate a normal lawn. 

It’s well worth researching the colours and finishes thoroughly and requesting samples of the different materials to make sure they fulfil your requirements. With artificial grass, you generally get what you pay for. 

The cheapest products look like the sort of bright green baize used by greengrocers, which is OK on a pitch-and-putt golf course, but not what you want in a garden.

Some of the the mid-priced grasses have individual strands of plastic that look remarkably similar to real grass. The strands are held upright by brushing a layer of fine sand into the pile. The sand will have to be renewed every year, and might need brushing occasionally to keep the strands upright.

In addition to the brand retailers mentioned previously, below we've included the top five most searched-for retailers for artificial grass:

You’ll need to remove any existing turf, then create a firm, level surface topped with a 25-35mm layer of coarse sand. 

Some artificial grass manufacturers also recommend laying a weed-proof membrane, depending on how densely woven the artificial grass is.

Bear in mind that replacing real grass with artificial grass severely disrupts soil ecology - the long-term effects of which are still unknown.

Yes, weeds can grow through artificial grass. But it's much less likely to happen if you prepare the ground properly and install a weed-proof membrane.

Some manufacturers claim you can get a decade or two out of an artificial lawn. But it all depends on how well it's laid , how well it's maintained, the level of foot traffic it endures, weather conditions and what's placed on top and underneath it. 

Artificial grass won't last as long as real lawn, though, so if you're after a longer term investment - and a more ecologically friendly one - we'd recommend laying turf instead.
