    Nice flower and pictures, Ron. Did you report the divisions into a different soil mix and were they also in a net pot? I've noticed when repotting Utricularia alpina that the largest leaves and tubers are the ones at the edge of the pot (normal pot, not net), basically the tubers seem to like touch the inside of the pot.

    I've been very happy with the growth I've seen using live LFS in a netpot - so that's my primary approach. However, when repotting the original Orchidioides (not Iperua), sometimes they can get cranky, initiate a dormancy & perhaps decide to die. One of my backup pots is the one with two flower stalks & the 1st bloom (above) - this plant is in a 3" regular pot (w/ 100% live LFS). From what I've noticed, Orchidioides abhor anaerobic conditions. The netpots help keep those conditions away somewhat longer than regular pots - especially as the pots get larger.

    I plan to experiment with an airy Nep mix at some point in the future (it's on my ToDo list) - but all prior media experiments that contained any peat did not fair well. I've also got some ideas about using that new Hygrolon as a media ...

    From what I recall, the tubers in the U. endresii were spaced all through the media. When I repotted this U. alpina back in 2011, the tubers were packed solid in the pot, like a bunch of marbles.

    I wonder what's wrong? I would think your conditions would be ideal - much better than my basement ..... your pots aren't sitting in water? Is there any liverwort on the media?

    Keep an eye on this hybrid - it seems that it might not have the good sense to slow down flowering once it gets tired. I just cut 3 or 4 stalks from one pot because 1) each stalk was very long with lots of buds/flowers and 2) there was only 1 small leaf left on the plant. I'm somewhat concerned that I waited too long...

    Some other random updates:
    - U. humboldtii that I stuck on an east-facing windowsill last year is sending up a stalk (my 1st for this species). This is the same windowsill that coaxed a flower out of U. reniformis f. courte (also my 1st)
    - stuck some tubers of U. campbelliana & U. jamesoniana on Hygrolon plaques to see how they grow
    - the small pieces of U. campbelliana that I placed on treefern plaques (back in Oct) have both sprouted new leaves & stolons
    All the best,
    Ron

    Sure. Most are buried in the moss but they are typically growing out from the junction that also has leaves. (there are also 2 tubers to the left of the highest leaf)


    .... but sometimes the tubers are there without any associated leaves (these two are probably the only ones I've seen like this). Full-sized ones are about the size of a grain of rice (give or take).

    hmmm. toes wet but not feet wet. Will have to look inside. had relatively deep layer of lava/perlite/bark then live sphagnum. But then i do see one of the liverworths also. Quelchii seems to be doing OK. finally making larger leaves this year.

    What's the texture of that like? I've seen pictures and it looks sort of woven.

    It is. It's a fabric - or like a fabric. If you haven't seen it yet, Goods started a thread on the stuff - has some good info & links. The one orchid guy has gone crazy with the stuff & apparently the plants have responded well (in one of the links).

    Here are the two experimental plaques I set up. The left side is Hygrolon on Epiweb with 2 small U. campbelliana tubers (1st time I've tried tubers that don't have leaves). The right side is Hygrolon over closed cell foam (pipe insulation from what I can tell) with a U. jamesoniana root and tubers (again - no leaves). I spiked both with pieces of moss from the original U. campbelliana slab.


    Here's a closeup showing the material. You can see the cross-section as well as the dimples they weave into the fabric - interesting stuff.
    All the best,
    Ron
