I started using Sanicat Pink last year and the trees that I re-potted seem to be doing well.
I used this mix.
4 Parts Sanicat Pink
2 Parts Grit
1 Part John Innes No. 3
1 Part Bark
If anyone can recommend a good mix using Sanicat I would love to hear about it. I have read somewhere (possibly on Harry Harrington site before he closed the the link
bonsai4me.com/Basics/Basicscatlitter.htm) that all you need is Sanicat Pink and 10% bark.
