I do dislike the sniffiness that raises its head on here every time anyone mentions artificial grass.
It may be the only practical solution for small or very shaded gardens where children are going to play. Stone or wooden decking are natural, yes, but they’re not friendly surfaces for children, and decking can become very slippery, not to mention providing cover for rats.
Might also add that a neighbour of ours has replaced wooden decking that was rotting, with a synthetic version.
A dd’s friend with two very little ones had artificial grass laid in
a small and very narrow urban garden where grass was never going to thrive for long. She also had well planted beds for wildlife. I dare say she’d have preferred a bigger garden with real grass but such gardens were impossible to find within her area and price range.
We had artificial grass laid in the very tiny garden - and even tinier lawn - of a rental flat. When I first renovated the garden from a very messy jungle I did have real grass laid, but after over 7 years, and despite very good tenants always, it was well past saving.
There are still planted beds for butterflies, and for birds to forage for worms in.
The surrounding mini ‘gardens’ are virtually all completely paved or concreted, with maybe a few pots, so I don’t see that ours is really worse.
