This bed is two weeks old it had alfalfa in between the rows. In the next two pictures you will see rows planted last week and how much alfalfa I use. Most of the alfalfa has broken down or the worms ate it in this bed. I will put more as soon as I get time. We raised red worms in my younger days, when we could not get cow manure for our worn beds we used alfalfa. Alfalfa is just unprocessed cow manure.
