dongliang_l Posted August 7, 2003 Report Share Posted August 7, 2003 it's been a few months now since i grow cobras, the big one i got from austin is doing well but today i just had a look, the tube of some of the big ones are turning brown and looks like it's gonna rot, i believe it's the flies and wasps in there doing that coz the same happened with my leucophylla. Does catching flies do that to the pitcher? is it normal? coz i doubt cobras rot from water. Quote Link to comment Share on other sites More sharing options...
Bob H Posted August 7, 2003 Report Share Posted August 7, 2003 It's too much food at once, isn't it? Quote Link to comment Share on other sites More sharing options...
Guest radmail Posted August 7, 2003 Report Share Posted August 7, 2003 yeah i'd definitely say it is too many flies, my large cobra lily is going the same way, they're too efficient at what they do! they start spotting with brown at the middle, then it spreads. but lots of new pitchers are coming up so the plant should be ok, as with yours? 8) Quote Link to comment Share on other sites More sharing options...
dongliang_l Posted August 7, 2003 Author Report Share Posted August 7, 2003 yeah tons of little ones, but some don't have a lid they're just a tube with a stringy end. Quote Link to comment Share on other sites More sharing options...
Bob H Posted August 7, 2003 Report Share Posted August 7, 2003 Sounds like the girls one our beach....no bikinis just stringy bits ;-) Quote Link to comment Share on other sites More sharing options...
Guest radmail Posted August 7, 2003 Report Share Posted August 7, 2003 stringy bits? hmm.. some of mine are like that, but only a few, there are normal ones as well. wonder what does that? too much/little sun? do you sit your cobras in water for long periods of time? i know they dont like that, they like their pots to be flushed through with water alot Quote Link to comment Share on other sites More sharing options...
Guest Aidan Posted August 7, 2003 Report Share Posted August 7, 2003 It all sounds entirely normal and your plants should be kept permanently standing in water. The one way you are guaranteed to lose them is by allowing the plant to dry out. Very small pitchers often don't form properly, hence the "stringy bit".

Guest radmail Posted August 7, 2003 Report Share Posted August 7, 2003 hmm... read in a book somewhere not to stand cobra lilies permanently in water. but i definitely will from now on instead i have been regularly watering them from overhead :) Quote Link to comment Share on other sites More sharing options...
Guest Aidan Posted August 7, 2003 Report Share Posted August 7, 2003 Overhead watering is fine, it can help to cool the plant in hot weather. It should nonetheless be standing in an inch or two of water at this time of year. Quote Link to comment Share on other sites More sharing options...
Guest radmail Posted August 7, 2003 Report Share Posted August 7, 2003 will do :) what is the best medium for cobras? at the moment they are in pure sphagnum and perlite.. didnt have any peat! should i change it? Quote Link to comment Share on other sites More sharing options...
Guest Aidan Posted August 7, 2003 Report Share Posted August 7, 2003 If they appear happy, leave them as they are. I have plants both in pure peat and peat/perlite. Quote Link to comment Share on other sites More sharing options...
schimatrix Posted August 10, 2003 Report Share Posted August 10, 2003 If they appear happy, leave them as they are.I have plants both in pure peat and peat/perlite. Hi Aidan, since I'm going to receive my first cobra and I'm quite worried (Will I be able to find sphagnum?), please could you tell me if I can avoid using it? Is it possible to treat it like a sarra (50% perlite,50%peat as compost, no sphagnum on the top)? Do you think I 'd better use a ceramics pot? thanks a lot for your help.. giuseppe Quote Link to comment Share on other sites More sharing options...
Guest Aidan Posted August 10, 2003 Report Share Posted August 10, 2003 Live sphagnum is not necessary although it looks better to have a layer growing on the surface of the compost. As I mentioned above, I have Darlingtonia growing in both pure peat and peat/perlite. If you want to use peat/perlite I would use a ratio nearer 75/25 than 50/50. Plastic pots are also quite suitable. Quote Link to comment Share on other sites More sharing options...
schimatrix Posted August 10, 2003 Report Share Posted August 10, 2003 sorry Aidan, ..and what's about vermiculite? Is it useful for cobras? giuseppe Quote Link to comment Share on other sites More sharing options...
Guest Aidan Posted August 10, 2003 Report Share Posted August 10, 2003 I would avoid vermiculite. Quote Link to comment Share on other sites More sharing options...
Guest smbgpd Posted August 11, 2003 Report Share Posted August 11, 2003 This time of year the pitchers on cobras are suscepuible to scorching if in direct sunlight for too long. Thats prob whats happening here. Dont worry too much, if young growth looks healthy then either chop the scorched ones out or leave em to provide a bit of shade. I've grown Cobras in pure peat, and varous peat/sphag/perlite mixes and doesnt seem to be much difference between them. DO NOT USE VERMICULITE cos it is mineral rich.
