I have a question regarding the availability of Diatomite, which is hard and suitable for Bonsai usage.
There are many threads over the recent years advising that suitable Diatomite for Bonsai is no longer available in Australia.
However, viewing the recent post from the APAB Exhibition from Canberra appears to show many trees are potted into Diatomite. Is this correct

Is someone able to advise us as to the medium which appears popular in Canberra

I have researched the availability of the many suitable Bonsai mediums that can be easily obtained without costly postage and was on the verge of conceding to the fact that postage was the only alternative. Then finally I found a source which is actually very close to me. They actually state in their write-up that their Diatomite is suitable in Water filtration's, Bonsai and many other Horticulture applications. I have attached a link to their site below.

Back to my original questions:
- Do the good folk of Canberra use Diatomite


- Is suitable Diatomite actually available in Australia

As of yet i haven't made contact with Mineraland, but plan to very shortly. I just thought I'd check with the Canberra members first.
Thank-you,
Kevin
