Ah yes, I throw tonnes of Rooi bos tea on the compost as well (well, a few bags worth). How do you find the eggshells? Even when I grind them down with a pestle and mortor I still see them in the compost a year later. I didn't bother last year because of that...
I am sure a fish would be great for the soil, I generally buy my fish fillited so tend not to have too many fish bones/heads
Oh, I am flushing for the first time ever and adding molasses. Well, when I say flushing, the last couple of waters on my personal stash is getting molasses.
