What does the word sparse mean?
as in.... " put various items where the grass is sparse.
as per miriam webster: thin, not dense. from the root meaning 'scattered'so basically, put the various items where the grass is the thinnest- aka where you can see the earth/dirt beneath.
It means they aint a lot of it and what they is is all patchy and scattered
it means where there is none or barely any.
Sparse means not full. Could be scattered looking. If the grass is sparse then it could use some filling in with either more grass or flowers.
Scarce less not there
