Can you lay artificial grass on grass?

It is not recommended that put the artificial grass on the grass.

there are two reasons.

1st, the natural grass can grow in the basement, then it will be full the artificial grass holes. the holes on fake grass are for the water drainage.
that will make the artificial grass life shorter.

2ed, the natural grass is not flat. if artificial turf on it, the grass will be broken.

We recommend the flat basement will be better for laying the synthetic turf.
