    U. reniformis Setup Good?

    Hello everyone!
    I have recently gotten a reniformis.
    I have it potted in a 14" net pot with a mix of LFS, orchid bark, and perlite.

    I'm keeping it drier as it gets established, as per a recommendation in a really old CPN article.
    Can it be kept like this successfully long term?

    Do you have any other comments on my setup?
    Thanks everyone!!

    it depends on what you consider long term...problem with LFS and bark is that they tend to break down which leads to compaction--the one thing these utrics hate. would be better if you used live sphagnum instead. the live sphag will continue to grow, preventing compaction.

    Do you know what 'size' it is ---- the diameter of the leaves when mature?

    No I don't know which one it is.
    I would have used live sphagnum if I had more than the 3 strands it came packed in.
    Thanks for the info about compaction!

    I grow several clones of both the larger & the smaller sizes. While they all grow well, the smaller versions are virtually bombproof and very vigorous. The larger size is somewhat more picky (however, Bob Z. has a large-form rennie that blooms all summer for him).

    The larger pot is probably a good idea but monitor it for going anaerobic (as Amp warns). When I first started to grow this species, I did multiple media tests - for me, they grew best in peat-based mixes (which is opposite what I found with all of the true Orchidioides). I'll probably try to use a very coarse Nep media with some peat in it next time I do some repotting - ideally in a large pot. Based on the people who have had (& haven't had) success flowering these guys - I'm inclined to believe that both seasonal photoperiod & temperature variation may be important (& possibly a winter drying-out period).

    So far, I've only had one clone flower for me - one of the weedier small forms - several months ago.

    This field trip thread is one I found very interesting (besides all the great pics). In it, the author noted:
    There were two forms of Utricularia reniformis there. One with small leaves, that was usually found in shady locations, growing as a reophitic in river margins, and other with big leaves growing in grassy swamps or partialy shaded swampy florest margins.
    This was the first (& only) time I've come across comments about different habitats for the two types.
    All the best,
    Ron

    I have the larger reneformis 'Big Sister' clone from BobZ. Growing it as he recommended, in a sandy peat.

    It's the pot in the back by the droso. Can't see anything other than leaves though.. sorry.

    That's similar to my setup - I used dried NZ Sphagnum moss/orchid bark/perlite mix in a mesh pot. I find that the plant prefers to grow from the bottom of the mesh pot, rather than the top. I think this is because it prefers the wetter conditions due to the pot sitting in a saucer of water. You can see in the picture below that the bigger leaves are those coming from the bottom of the pot. Mine really slowed down a few months ago and I thought I was going to lose it, with the leaves getting smaller and less of them but then I fed it with plant food and it has put on a growth spurt.
