sundewmatt Posted May 12, 2006 Report Share Posted May 12, 2006 I've got a few very nice Utricularia humboldtii and want to make more... Will this one respond to leaf cuttings? If so, would it be possible to cut off just the tip and place it on the medium? I see stolons growing out of the soil, but as of yet I have not gotten any new plants- and it's been a long time. Thanks Matt Quote Link to comment Share on other sites More sharing options...
Howard Snocken Posted May 12, 2006 Report Share Posted May 12, 2006 I have tried leaf cuttings several times but to no avail, so I would also be interested to hear if anyone else has had success with this. My plant, however, spreads rapidly and is relatively easy to propagate by dividing the mass of stolons it produces. Quote Link to comment Share on other sites More sharing options...
sundewmatt Posted May 12, 2006 Author Report Share Posted May 12, 2006 Thanks Howard. I think the issue with mine is that it was previously in very small pots. Now I've got it in a bigger pot, but it's probably still not wide enough for good vertical spreading. Is yours in a wide, shallow tray?

Howard Snocken Posted May 13, 2006 Report Share Posted May 13, 2006 Is yours in a wide, shallow tray? Sort of. I keep the main plant in a round glass tank 25 cm wide by 30 cm high, covered with a sheet of glass to keep the humidity high but held a few mm above the tank rim with 'spacers' to allow some air circulation. The growing medium is pure live Sphagnum kept permanently waterlogged and light is provided by a flourescent tube standing next to the tank ( like this I can have several such tanks on top of each other which works well, saves space and looks quite good too ). Growing under these conditions my U. humboldtii filled its tank in a couple of years to such an extent that I had to literally slice apart the mass of intermeshed stolons! I have had little success trying to confine this plant in small pots and the like, so I think you are right that this was the issue with your's. Let it roam, then round em up !

JanW Posted May 13, 2006 Report Share Posted May 13, 2006 I keep mine in a 13 cm square pot. At the ground there are clay pearls with living Sphagnum moss on the top. I mixed some peat in the substrate. The plants are sitting in the moss and grow happily. I grew the plant in the same substrate in a 7 cm pot root bounded and it was producing runners at all times, now it seems to fill the pot again and then I think it will start over with all those runners.

Markus Berg Posted May 14, 2006 Report Share Posted May 14, 2006 Hello, my U. humboldtii propagates itself through stolons, so I have now some U. humboldtii growing in my Brocchinia reducta as well as in some pitchers of Heliamphora heterodoxa x ionasii. My plants is in a small pot (9 cm), I filled the pot 2/3 with dead, milled sphagnum and planted some living sphagnum on the top. The sphagnum has now reached a height of 10 cm, so I use it when I'm sending plants. I found U. humboldtii is a very easy and nice species. It has not yet flowered so far, and I'm sure that the pot is not big enough for it - but unfortunately I have not more space.
