Yossu Posted July 16, 2017 Report Share Posted July 16, 2017 (edited) I have a Nepenthes Ventrata, whose two original branches had reached about seven feet long each. As some of the lower leaves were dying off (see this thread for a pic and the advice I got about it), I decided to have a go at snipping them down and propagating new plants from them. I followed a video that Welshy (think he changed his name to North West Neps or something similar recently) showed me ages ago, and now have about 25 cuttings sitting in a propagator under a full spectrum light. See below... The cuttings are in plastic cups of deionised water, with about 4-5 cuttings per cup, and the propagator was been partly filled with more water to make it really humid in there. I'm wondering what levels of light and humidity I should aim for. The video said to keep up the humidity, but my plant was sitting on a windowsill, so not subject to much higher humidity than a normal houseplant would get. I did get a bit more, as it was sitting over a tray of waterlogged clay pebbles, but the levels in the propagator are significantly higher than that. I haven't put a meter in there to measure it, but there are quite a lot of water droplets condensed on the clear lid, so it's obviously quite humid in there. The light was bought from eBay, but thanks to their hopelessly vague email, I'm not sure exactly which it was. I think it's a 36W cool white LED bulb. Anyone able to comment if I'm doing this right or wrong? This is my first go at this, and I'd like to get it right. Thanks Edited July 16, 2017 by Yossu Quote Link to comment Share on other sites More sharing options...
JMHoff Posted July 16, 2017 Report Share Posted July 16, 2017 You can not fail with a ventrata. I cut several basal shoots a couple of months ago, bagged them and placed them everywhere in the GH (some in very dark places). Every single one rotted. Cuttings want high humidity (up to 100%) in order to develop the roots, so it does not matter if the mother plant is in a 20% RH all day long. As a rule, with other more demanding neps, I give the cuttings exactly the same amount of light as the mother plant receives. Quote Link to comment Share on other sites More sharing options...
Yossu Posted July 16, 2017 Author Report Share Posted July 16, 2017 Did you mean "Every single one rooted"? Thanks for the reply. I'll leave them there then. I don't reckon I can get higher humidity than they are getting. Will I need to acclimatise them when removing them from the propagator? When they root, I'll want to plant them, and they will have to come out of there. Will they need to adapt to lower humidity? Thanks again.

JMHoff Posted July 16, 2017 Report Share Posted July 16, 2017 Yes, I meant ROOTED, typos are my speciality nowadays. Ventrata is a VERY forgiving nep so they might be fine with a short acclimatization to lower RH. Quote Link to comment Share on other sites More sharing options...
fltropical Posted July 17, 2017 Report Share Posted July 17, 2017 Mine sit in full deep shade all day, in a cup of damp LFS. And that's it. They root faster when it's warm, but root in the cold too. They don't seem to care about humidity. 1 Quote Link to comment Share on other sites More sharing options...
Yossu Posted July 17, 2017 Author Report Share Posted July 17, 2017 OK, thanks to both of you. Mine are actually fairly warm, as they are in my office, which stays a fairly constant warm temperature. Any idea how long I'll need to wait? The video said a couple of months, but I don't know how the different environment would affect them. I'm just impatient!

Yossu Posted July 23, 2017 Author Report Share Posted July 23, 2017 Hmm, been a week, and two of the cuttings have gone brown and look pretty dead. Should I leave them, or pull them out? Quote Link to comment Share on other sites More sharing options...
manders Posted July 23, 2017 Report Share Posted July 23, 2017 (edited) Seems odd they went brown that fast, cuttings can stay green for months if not years without doing anything. Edited July 23, 2017 by manders 1 Quote Link to comment Share on other sites More sharing options...
Yossu Posted July 23, 2017 Author Report Share Posted July 23, 2017 I was surprised, which is why I asked. Any suggestions? Should I remove them? Anything I can do to prevent the others doing the same? Thanks Quote Link to comment Share on other sites More sharing options...
manders Posted July 23, 2017 Report Share Posted July 23, 2017 It shouldnt matter if you leave them in although i like to get rid of dead ones just to keep things tidy. I wouldnt worry too much about it either unless a few other ones start to brown off, neps can be funny and die off for no obvious reason. The rest should root well enough.

Yossu Posted July 23, 2017 Author Report Share Posted July 23, 2017 OK, thanks. I'll see what happens Quote Link to comment Share on other sites More sharing options...
