    I figure it is time to repot my little bical from a 4" pot to an 8" round x 7"deep. I have read that there should be about 1" of "orchid" mulch at the bottom. What in the world is orchid mulch...ground up orchids? [img]http://www.**********.com/iB_html312/non-cgi/emoticons/smile.gif[/img]
    Would cypress mulch work also?
    I have also been told that bicals (as opposed to other nepths)should be grown in pure LFS. Is there a general consensus that this is the way to go? [img]http://www.**********.com/iB_html312/non-cgi/emoticons/rock.gif[/img]

    Hi Lauderdale -

    Everyone has their own particular mix, here's what I used for my bical & other neps:

    First, I put about 1/2 inch of LFS in the bottom of the pot.

    The mix is equal amounts of:
    LFS
    Orchid Bark (chopped to 1 to 1/2 inch size, if they came in really big chunks).
    Vermiculite
    Perlite
    Sand
    Peatmoss
    Lava Rocks, smashed with a hammer
    Aquarium Charcoal, smashed

    It works well for me. I got a small N. bical plant last August. It's in a terrarium and now has four 2 inch pitchers on it (a little traumatized from sixty 4th & 5th graders poking it last Monday - it will bounce back just fine). It will be interesting to hear what other growers recipes are. I use the above recipe for all my neps, however, for my N. villosa I added smashed granite chips at the suggestion of Phil Faulisi of the Bay Area CP Society.

    Good luck with it.

    Hi Jan and all,
    I've heard good things about granite chips as an additive to Nep mixes, but have never used it. Granite chips are hard to find in south Florida.
    Jan, for our south Florida climate, you could use a "traditional" Nep mix-peat, sphag., orchid bark,charcoal, aliflor, perlite, or preferably, pumice. As you have seen in our greenhouse, bicals are one of the few plants we grow exclusively in lfs. If you intend to grow the plant outside thru the summer, I'm not sure about using pure sphag because of the extended rainy season causing them to be too wet and thus prone to rot. For outdoor south Florida growing, I would suggest more the traditional mix, but without the perlite. Use aliflor (little clay balls) to help provide better drainage. Perlite with time will break down and leach Fluorides into the media-very much to the displeasure of N. bicalcarata. If you grow them under cover where you can control the water schedule, then stick to the lfsphag.
    see ya around,
    Trent

    Granite chips are form granite correct? The pretty metamorphic rock right? If so...I have a quarry of it behind my house, would it be in my interest to ground up the smaller granite chunk with a hammer to "chip" dimensions and use them as an additive in Nep mixes??

    Hi Dustin,
    I've heard only good things about granite chips. I've even heard that they leach out beneficial minerals to the plants. I know of some growers in Georgia who use granite in all their cp mixes. The chips are actually graded and sized, and sold in bags in the Atlanta area.
    I'm not sure about this, but doesn't Atlanta Botanical Garden use granite chips in their Nep mix?

    Hey There,

    I have two comments on this thread...

    1) Granite Chips are available at feed stores and grain elevators as "chicken grit" or "Turkey Grit". The Turkey Grit is a bit coarser and is a good size for potting mixes. In case your wondering about the name, poultry rely on small pebbles to help grind up the food in their stomachs, so these products are added to their food... I have never used them in CP mix.

    2) I think the best mix for bicalc is pure LF sphagnum. Other growers do well with lots of different mixes, so itís not the only thing that will work, but for me LFS is the only thing I grow bicalc in.

    Good Luck!
