Grass

[lapis quarry]

Hi
I'm wondering how many days it takes for grass to spread. I want grass that's flat and green.
I want my grass to look like other people's grass
(I saw their grass at coral farm layout)
Please help
Thanks!

The flat green grass tiles commonly seen in layouts is a decor path tile! It’s unlocked later on at a higher town rank iirc

Is grass starter for my cows?
