We had artificial lawn pit down about 7 years ago which wasn’t ideal but our garden was so awful and we’d spent £1000’s of pounds having gardeners in to try and improve the soil (as it was horrendous) plus have it re-turfed twice. None of it worked and our garden was permanently awful with consistently dead grass or bald patches where grass wouldn’t even grow 😢
We had two young children and ultimately we wanted a garden that they could use and so rather than continue paying out to try a fix problem that we’d already tried to fix twice, we just had artificial lawn put down.
The downside, like a previous poster said, is that the grass gets so hot when the sun is out that you cannot walk on it barefoot or lay your hands on it for much longer than 10 seconds.
Also, when it rains there is no mud to soak up the water so the grass gets wet and even going out the next day can still result in getting wet socks or wet resulting in wet foot shaped patches through the house.
We do still have lots of little bugs in the garden as they all live between the cracks of the patio and on the lining of the artificial grass. We also have loads of potted plants in the garden so we still get bees and butterflies and little insects creeping around in the soil. It’s not as ideal as natural grass obviously but the insects we do get seem happy enough.
I’ve never washed the lawn but I have swept it a few times, normally in the autumn when leaves off the next door neighbour’s tree drop into our garden.
It may not be considered as good for the environment but a lot of things aren’t. As a previous poster said, driving and flying aren’t good for the environment either but that doesn’t stop people doing it. I don’t think my small artificial garden is anywhere near as damaging as other factors that affect the environment.
We would have much preferred a natural lawn but it wasn’t to be for us.
So yes, there are upsides and downsides to it, as there are with most things in life, so just weight it all up OP and go with whatever decision suits you best.
