While sawdust is listed as the last ingredient, thus supposedly the smallest amount, and I certainly would not return it, and I would use it, I just want to make a point about sawdust in general: It is not a good ingredient to add to any garden. Why? First off, it robs the soil of the all-important Nitrogen. The Nitrogen in your growing medium is automatically used up in breaking down the sawdust first before what is left gets to your plant roots. Secondly, in my personal experience, sawdust attracts all kinds of different "bugs"! In particular, what we used to call when we were young, cutworms, which I noted some years ago, no one else calls them that. They are, full grown, about an inch long, very thin, brown in colour, and move very slowly, like a centipede. They have a hard shell. I have upturned soil just a year ago, that I had put a fair amount of sawdust in, and it was full of all sizes of this insect, curled up, in breeding circles. Cheers!
