100% diatomite for soil?

Yep. Me too. Simple.

Funny since I posted that I started using a Organic Nursery type mix I make myself. Plants do just fine in it and require a lot less maintenance. It drains very good here and looking at it over a couple of years I am certain I have better roots now and more robust growth.

Not certain why as I spent a lot of time on everything when inorganic :confused:

Can't get pumice cost effectively here

Your mix the plants came in seems to be fine. I will most likely just repot 1 or 2 of the 12 this season giving them a little more space.

I just wanted you all to see what DE did at the bottom of a pot at 115F after 4 hours.
You're preaching to the choir here.
I know all about how good this stuff is.
I don't get to try it out at 115 degrees though.
Thank God.
 
Could you reveal what's in it? PM if you'd rather.:cool:

I have been using 1/3 each of Fafard Topsoil(pure black compost very fine ground), Course Silica sand(any brand, I have Quikrete this year), and Horticultural Perlite. If it is a acidic loving plant I add a generous amount of Canadian sphagnum peat moss. Either combination drains the same as ANY inorganic I have tried and allows great root growth. For much larger potting I also add Pine bark mulch instead of the Canadian sphagnum - in 12 to 15 gallon pots it drains far better ;)

Thanks Grimmy. That's a radical change. I don't see how it can drain as well as pumice with all the fines but I'll bet you don't have to water as much. Wouldn't mind that at all.
