Thank you for this, it was very in depth and even confirmed my long standing lack of confidence in the Tesco cat litter mix I am trying. I didn't realise it was as well known as this.
Is is a very thorough and well explained article. I guess what I got out of this for my work is that I’ll put a “drainage layer” in most of my taller pots and leave it out of my most of my shorter pots.
