Hi all,

Is anyone growing Utricularia longifolia at the moment or has done so in the past?

I have just orded one and it is my first Utricularia, any tips will be gratefully received.

Regards

Andy,

I find longifolia a bit awkward.  It does ok in live spaghnum and likes plenty if water, it can turn allmost aquatic spreading into trays etc.  Seems to flower best if given a cool winter.  I think it likes warmth and plentry of light the rest of the year.

interested to hear what others say, mine has struggled a lot since i moved it in the greenhouse.

Thanks manders, I'll keep it in a separate tray and put it in the bathroom over the winter, we always keep the bathroom window open, so it's cool in the winter for it.

Hi Andy I've been growing some for a few years and my experience sounds similar to manders. Mine grows in live sphagnum, in a greenhouse heated to about 8C in winter.  It never thrives, always has some purple spots that sometimes grow mildew.  I tried putting it in the shade then in brighter light, always the same.  It became pot bound so I split it last year and tried some in a more peaty type mix, it seemed to spring to life but this year is back to "normal".  Average leaf length about 4cm and last year the best was maybe 8cm so not so "long"ifolia in my experience.  I have never been able to get to flower yet.

My U alpina and U nelumbifolia grow just fine so I don't think it's just my lack of aptitude but who knows.

Manders' description of "awkward" seems to describe it perfectly.

I hope you have better luck and when you do don't forget to come back and give us some much needed advice.

Hi Gaz, cheers for the info mate, I have been reading a few old posts ,and it looks like there have been a few people having the same trouble with U, longifolia.

I'm not looking forward to getting it as much as I was now! Hahahaha.

I'm sure it'll be a challenge, but that's why we grow CP's isn't! Lol

Hi Andy, don't let it put you off, as you say the challenge is part of the fun and not every growers conditions suit every plant.  Good luck and remember to take some photos so we can admire your plant :tu:

I grow one and it's currently going through a growth spurt. I grow it in a west window, water level up to the top of the pot which I allow to occasionally go half way down the water container then I refill it.

Mine is in a bathroom windowsill with bright, diffuse light. Been there about a year and is growing like a weed but no flowers so far. It is in peat which i basically flood when watering. I think mine needs moving up to a larger pot though as it has filled this one and is spreading over the sides.

I've been growing it for a few years. It grows like all terrestrial bladderworts, but I had problems with some kind of purple fungus on the leaves. It doesn't kill the plant, but it seems to weaken it, so my leaves are rather short. It didn't flower so far for me.

I had it outside next to my sarracenia since spring. Now I let it experience some colder weather and let the substrate be only damp and no longer wet. It now has many leaves, which are all rather short. A few days ago I moved it into the house, removed all leaves that had signs of that purple fungus and placed it into a 15-liter terrarium net to me Nephentes x 'hookeriana'. I'll see how it will grow.  If the fungus appears again, I'll use a fungicide. I divided a small clump from my mother plant. I'll use that one to test the fungicide, just in case.

Next year I'll repot my plant before I'll place it outside. Hopefully, something will finally please it and it will flower. I heard people saying that U. praelonga was hard to convince to flower, but that wasn't a problem with me. It bloomed like crazy every year if I placed it during the winter onto a bright windowsill in the basement, where it was around 5 °C. U. longifolia, on the other hand, grows like a weed, with or without the purple fungus on the leaves, but there are no signs of it wanting to flower.

It is a mildew, but there are many different species of it. The species you see on grapes and cucumbers isn't the same as the one that is on my U. longifolia. That also means that the same fungicide might not be effective. I'll test it in the following days and report on how it worked later.

Do you guys feed your U, loinifolia, if so what do you feed them?

No, haven't tried that.
