A garden designer’s honest verdict (and what I’d do instead)
Let’s get the disclosure out of the way early, because it’ll save you reading the rest of my ramblings waiting for the twist: I’m not a fan of fake grass. There, I’ve said it. I know that’s not a wildly controversial stance for someone whose entire career is built on things that actually grow, but I still think it’s worth explaining why, properly, rather than just tutting at it from a safe distance, say on the fence!
Because fake grass isn’t going anywhere, it’s genuinely solving a real problem for a lot of people.
So here’s the honest version: what fake grass is actually good at, where it falls down (sometimes literally, in the heat), the bit almost nobody talks about, and what I’d genuinely suggest instead.
What it’s actually solving
Nobody buys fake grass because they’ve fallen in love with plastic. They buy it because real lawns are, frankly, a lot of ongoing work for a result that a wet British summer can undo in about four days. Mowing, feeding, scarifying, dealing with the bald patch where the trampoline used to be, watching it go from lush to swamp to bald depending entirely on what the sky’s been doing that week.
Fake grass promises to end all of that in one afternoon of installation. Always green, never muddy, no mower to store, no weekend lost to lawn admin. For a family with young kids who just want a clean, usable patch of “green” to kick a ball around on, or anyone who’s simply tired of a lawn that looks worse the harder they try, I genuinely understand the appeal. This isn’t a piece written to make anyone feel silly for considering it.
Where it quietly falls apart
It gets hot. Properly, alarmingly hot. On a warm summer day, artificial turf can reach temperatures significantly higher than the air around it, hot enough that bare feet, paws, and small children sitting down on it all have a genuinely bad time. Real grass, by contrast, actively cools itself through evapotranspiration, which is a fancy way of saying it sweats, gently, all day, and stays pleasant underfoot even in a heatwave. Fake grass has no such trick up its sleeve. It just gets hotter and hotter and radiates it back at you like a slightly resentful griddle.
It’s an ecological dead zone. A real lawn, even a modest one, supports soil life, worms, insects, the odd confused bee having a wander. Fake grass sits on top of the ground like a tarpaulin, offering precisely nothing to anything that isn’t a human standing on it. In a country already worried about pollinator decline, covering good soil in plastic sheeting is, ecologically speaking, a bit of a own goal.
It doesn’t actually eliminate maintenance, it just changes what the maintenance is. You still need to brush it to keep the fibres standing up, hose it down to stop it smelling (particularly if you have a dog and I promise you, you will notice), and remove leaves and debris that would otherwise compost into the “soil” it doesn’t have. It’s less maintenance than a lawn, certainly, but “zero maintenance” is doing some very optimistic marketing work.
And here’s the bit almost nobody puts in the brochure: off-gassing. Artificial turf is, unavoidably, a plastic product, usually polyethylene or polypropylene fibres, often with an infill underneath, sitting outdoors in direct sun for years. Plastics exposed to sustained heat and UV do release volatile organic compounds as they slowly break down, and that effect is worse, not better, on the hottest days, which is exactly when people and pets are lying on it. It’s not something that gets discussed nearly as often as the drainage specs or the pile height, and I think that’s a genuine gap in how this product gets sold. I’m not going to pretend I can give you a lab report in a blog post, but as someone who spends his working life thinking about what’s actually good for a garden and the people using it, it’s a real enough concern that it’s part of why I steer clients away from it, not just an aesthetic objection dressed up as a health one.
The bit where I admit it’s not all doom
To be fair to fake grass, the quality has genuinely improved. The better products look considerably more convincing than the bright, primary-green astroturf of a decade ago, drainage has improved so it’s less of a swamp underneath in wet weather, and for a genuinely difficult, low-light spot where real grass has never once thrived, it can be a reasonable last resort rather than a first choice. I’d rather someone have a small, well-installed patch of fake grass than an ongoing losing battle with a lawn that was never going to work in that spot anyway.
What I’d actually suggest instead
If what you’re really after is “always looks green, doesn’t need constant attention, kids and dogs can use it without wrecking it,” there are real alternatives that get you most of the way there without the heat, the plastic, or the eventual off-gassing question mark.
A tougher grass-alternative ground cover. Low, hard-wearing plants like chamomile or creeping thyme in a low-traffic area give you green, textured coverage that smells wonderful when walked on and needs nothing more than an occasional trim.
A properly chosen hard wearing lawn seed mix, sown for actual use rather than showroom looks, copes far better with kids and dogs than people expect, most “my lawn’s a disaster” stories trace back to the wrong seed mix for the job, not an unfixable lawn.
Gravel or bark with structural planting around it, for a genuinely low-maintenance, no-mowing solution that still supports soil life and doesn’t turn into a frying pan every July.
Or, my actual favourite: shrink the lawn, don’t replace it. A smaller, well kept patch of real grass surrounded by naturalistic planting is often easier to maintain than a full lawn ever was, and it gives you everything fake grass promises tidy, green, low-effort, without a single one of its downsides.
The honest verdict
Fake grass solves a real problem badly, when there are usually better solutions to the same problem that don’t involve plastic sheeting, summer heat spikes, or a slow chemical release nobody quite wants to talk about. I understand exactly why people reach for it, and I don’t think anyone’s foolish for considering it but if you’re weighing it up because you’re tired of fighting a lawn, that’s precisely the conversation worth having with a designer before you commit, not after.
If your lawn currently feels like more trouble than it’s worth, that’s usually a design problem, not a grass problem and it’s exactly the sort of thing I, Owen Brooks from PurelyPlanting sort out for clients across Sussex, real grass or otherwise.
Definitely real grass, as mother nature intended!!
