Biochar recommendation
« on: February 06, 2015, 05:50 PM »
So, I have read enough to convince myself that charcoal is a good ammedment to my soul mixes. However, it is hard to find enough minutia concerning particle size, breakdown info and perhaps a "brand". Anyone have thoughts on these variables or any thoughts to help facilitate purchasing. Also, I rutinely add micorhizae powder to collected conifers, but some biochar comes with it added already, it that abetter delivery system? I have mostly collected native (to Colorado) conifers, but also have acquired many deciduous trees over the years. Thanks in advance.

I have, in the past, added charcoal I get from orchid suppliers. I just bought some biochar from http://www.biocharsupreme.com/ since I'm out of charcoal. I am interested in this additive and look forward to what others have to say.

I like Hoffman Agricultural Charcoal, it has consistent grain size and holds up well.  The bags are not very big, 24oz, but it is readability available at most garden centers.  Nomatter what brand or source, you have to sieve to remove dust and fines.  After Sieving I use the same size charcoal as the grain size of soil media to retain cosistent permiablity.  I then inoculate my soil media after repotting since I use a inorganic based (pumice and lava) media mix.

I use Hoffmans as well for the same reason of particle size.  I got some once from an online orchid retailer, and the particles were everything from dust to 3/4".

Okay. Thanks everyone.
Just a quick follow up...the description I see for Hoffman is "pellet size", does that imply a consistent size or variable size pellets? Perhaps I am over thinking, but ideally I would like to match partical size to my soil mix size as EJ alluded to. Judy or EJ, your thoughts?

Thanks John.

Regards,
Patrik

It seems to match up well with my soil, I use akadama small, hyuga small and 1/4" lava mix.

Thanks again everyone. I'm going to order some now, probably from Amazon too.
