    What mix does everyone grow their plants in? I have mine in Peat/sand, but I think it may grow better in some other soil.

    The bulk of my Utrics are small species and they are in coarse sphagnum peat but some like: longifolia and calycifida are in long fibered sphagnum that is kept very wet but drained and sitting in 1/2" or so of water all the time.

    I too have been wondering if perhaps a coarser soil mix (like a 50:50 blend of LFS and small orchid bark) might be better for the larger epiphytic utrics.

    Since calycifida grows as a lithophyte (at least occasionally) I wondered how I might copy this at home?
    Perhaps a 12" glass fish bowl 1/2 filled with rocks and living sphagnum and some divisions of calycifida? Anyone ever try growing utrics lithophytically? How did you do it?

    Hmmm, this is getting off topic, but it is a worthy question. Maybe Pyro can set this up in it's own topic. This question is often asked :-)

    I grow most all my plants in fluffed up pure peat, or live sphagnum. Adding sand does nothing, and I feel it compacts the medium too much. I have experimented with various other things, but these 2 seem to fill all my plant's needs. I have noticed that, once established, the Utricularia that have made it into my pots containing live sphagnum have just done better than in any other medium. When I try to get material established in live moss, I have the devil of a time doing it! I plan now on establishing the new starts in pure peat, and then transplanting into milled live LFS, possibly with a little bark for aeration. I feel more and more that the plants need air about their stolons. It's an oxygen thing. After awhile, the water they sit in gets stagnant: in habitat there is usually a slow seep that is carrying oxygen beneath the surface.

    I fairly recently started keeping carnivorous plants, but I feel I may be able to add to this thread.

    I recently obtained my U. praelonga and it has not flowered, but I have had numerous conversations with those who are successful with theirs, and I am told that praelonga prefers to have the water level about even with the soil level, and that it enjoys occasional flooding.

    Under these conditions I understand that it should flower. I also suspect that it may be worth the effort after keeping a plant in this manner for an extended period of time to experiment by lowering the water level to see if that induces flowering.

    Hope this helps!

    Welcome to the forums Kayaker78!

    You're right about praelonga liking a lot of water, and many species of utrics do flower when the water level drops.

    I wonder if it could be some combination of water level changes and another cue, probably temperature and/or light.

    Hi Bryant,

    I have my plant underwater currently and its been like this for 2 months. I am holding my breath: if something is going to happen I think it will be soon when the plant returns to growth. After I get some aboveground growth, I will start to dry the plant off. I figure thats about every durned cue that I can give it. It is pot bound, went through a cold winter dormancy including a freeze, has been under natural photoperiod, semi-aquatic and about to dry.

    Anyone got any fairy dust?

    Looking at my plant today I noticed there are numerous things poking up: a forest of them! They are not green like the grass like leaves, and they are round in cross section, not flat. I think they might be scapes!
