I was told this by a hosta breeder in Ohio. He said you can get two years growth from one year using this. I bought mine as Alfabits for horses. It was pure Alfalfa Meal. I can't get them any where near me now. The place I used to buy them closed down. If possible rabbit dune is suppose to be even better. I don't have any way to get that.
I was afraid if I used too much, It would draw mice or moles in my garden.
