There are numerous threads on diatomite on this website so do a search.Luke308 wrote:Thanks Grant, very helpful.
I've never heard of Diatomite before. I just "googled" it and it seems it is available from Hydroponic stores, is that correct? Is there any particular brand you would recommend? Also, is that a typical analysis of the potting mix you would use for maples? Also the coconut fibre you referred to, does that come in solid bricks as coir fibre?
Thanks for your help once again. I'm learning so much from this site, I don't know how I managed without it
Also search for potting mix trials etc.
The Diatomite in hydroponics stores were too large; 15mm plus.
Get Maidenwell or Mt sylvia Diatomite in 2mm to 6.4mm approx.
Yes Coir fibre comes in bricks that swell up in water.
The mix above is roughly what I am using for everything except azalea where i use Kanuma.
