Theo, I believe lucerne hay is alfafa. (I also think it may have been used
for burlap bags back in the old days before plastic became common.)

Mulch. Ah yes! reams have been written on this subject and
there doesn't seem to be any consensus. Everything from wood chips
to straw to peanut shells to cocoa shells to stone chips to char coal
to Lucerne Hay(don't ask me what that is!!) has been promoted here.
I'm sure they all work.
