My father used to own a bonsai nursery and made his own soil. I have only used his and it was wonderful. Since he passed away and I no longer have any of his soil left, I was very hesitant about using anything else. I even tried to use his recipe to make my own - didn't do something right! This is a very good product and even though it could never rate to be my father's (of course not) it is extremely good and I will purchase this again.
