I've found one of two things happen. Either the grass dries out and blows
away or it turns to sillage and stinks. I mix mine with leaves and it all
seems to turn to leaf mold together (or at least it seems to - we have
mainly Oak leaves which take a while).

Is there any good reason why I shouldn't mulch my grape vines with grass
clippings?
