    Use of burnt earth as media

    The local CPers started a year ago with the use of burnt earth (aka burnt clay or burnt soil) with their Neps. This media is used in general gardening to increase drainage. Here is the thread on the local forum if anyone is keen to take a look. http://www.greenculturesg.com/forum/...howtopic=11805

    The change was wonderful for N. northiana, which responded exceedingly well. Then we decided to use it for N. campanulata and N. merrilliana as well. The results are amazing!

    I have got no idea what is the pH is or the mineral content is(pretty high from the salt build-up). But well, it works.

    N. northiana - arrived bareroot in June this year, now pitchering on the leaves formed here.


    N. campanulata - arrived bareroot in June and July this year




    N. campanulata - these are plants grown in sphagnum moss and large pieces of orchid media (similar to pumice) under the same conditions as the ones above; I changed them into burnt earth yesterday

    wow, that' really cool.
    so do you use burnt earth as an addon or as a media by itself?

    The media is 100% burnt earth. I have some northiana in a mixture of shredded sphagnum, pumice and burnt earth but I have not noticed any difference in growth yet.

    Fantastic campys! I used your media recommendation for them off the other forum (1:1:1 LFS, perlite, coral) but mine isn't doing so hot.

    Your burnt earth looks just like what we call lava rock.

    The media is sold as Indonesia burnt earth. I assume it simply means it is from an Indonesian source. The media is heated rather unevenly so there are some chunks which will crumble once you water it. Other chunks are rock solid and are rather similar to bricks.

    This kind of harkens back to Rob's photos of the fields of N. rajah. I wonder if there is some trace elements in the clay that the Neps really like??

    I may have to do a little tinkering with some of the local clay here... Wonder if I can "burn" it in my spare grill?? Oh fun tinker time...

    Burnt earth??

    Is it a type of Fuller's earth?? It looks more like lava rock and/or pumice.
