My question is - why are not the air and sun dried grass clippings not considered a brown?
They are, they are! That’s why I said to go for it.
I’ve just always been stuck with loads of brown leaves; I just figured everyone else was, too.
But dried grass clippings are a great “brown.” Provided the grass is frequently mowed, there is no reason why they need to be removed from the lawn (hence my golf course comment).
