They stopped making supersoil
They do not sell the supersoil in the yellow bags anymore. They make other kinds, but they are not as good. I bought some of the supersoil vegetable compost mix and it was mostly steer manure. I am pretty upset about this.
I am talking about the garden soil in a bag and not this sort of compost sludge called "supersoil" that they use for greening lawns. It sounds like a horrible product, anyway, and the name they took has been used. Supersoil should be a name for soil and not for liquid sludge.
So, I now am taking back the good things I said about supersoil helping my garden. That was the old supersoil, that they do not make any more that was good for my garden.
