Martin_mtl Posted April 11, 2006 Report Share Posted April 11, 2006 My N. sibuyanensis has brown leaf damage. Anybody can tell me what it could be? I am in dilemma as if I should repot it in pure LFS and/or put it in shadier conditions... thanks in advance! Quote Link to comment Share on other sites More sharing options...
SPECIALIZED Posted April 11, 2006 Report Share Posted April 11, 2006 looks like it is sunburn..... What type of soil is it potted in? Was it in full sun? Once my leaves lose their pitcher they have a tendancy to turn yellow and then brown but this is quite some time after they lose their pitcher. Actually I don't know if this is suppose to happen either. It usually starts from the bottom area and works its way up but has not gone very far. Nothing of what yours looks like. The newst leaf near the top left seems to be fine as it is the newest leaf to open. I would move it to the side/shade for a week or two and then move it "slowly" back into the light. Just my two cents but I grow everything under lights. Quote Link to comment Share on other sites More sharing options...
gardenofeden Posted April 11, 2006 Report Share Posted April 11, 2006 for me this is normally cold shock... Quote Link to comment Share on other sites More sharing options...
An D Smith Posted April 11, 2006 Report Share Posted April 11, 2006 Hi Martin I have had similar problems on a couple of my plants in the past and eventually found that it was stress induced by the environment. Often water drops on the leaves when the temperature drops too low or when the sun comes out and shines on the wet leaves will cause this mottling. There is a fungal infection which affects Neps in a similar way but I have never had this with my plants and have never seen it on anybody elses. Do you find N. sibyanensis slow?

Tim Posted April 11, 2006 Report Share Posted April 11, 2006 Without commenting on the top of the leaves or the cause of it on my plant, which I've had for three years, the bottom of the leaves look just like yours. And it's the only one in my collection that looks that way. Quote Link to comment Share on other sites More sharing options...

Martin_mtl Posted April 11, 2006 Author Report Share Posted April 11, 2006 Thanks for the replies! I think I am keeping this one too wet...this would have encouraged an infection. I have a tendency to overwater! I will repot in LFS and treat the roots with fungicide. Quote Link to comment Share on other sites More sharing options...
Martin_mtl Posted April 11, 2006 Author Report Share Posted April 11, 2006 Do you find N. sibyanensis slow? Yes, but not as slow as N. lowii Quote Link to comment Share on other sites More sharing options...

chesara Posted April 12, 2006 Report Share Posted April 12, 2006 HMMM looks like its had a chill i had many plants like that and much much worse at -7 but be patient as they are tougher than you think most of my plants are coming back from that freeze so be patient .I would ditch the soil its in and go for pure LFS can beat it really. Yes Sibuyanensis is "i find"is a funny grower sometimes goes in fits and starts,ive recently put it in a huge pot of LFS and an giving it almost unfiltered sunlight for most of the day and its looking better ,the leaves have gone very thick and rubbery and are looking well,im just hoping its going to start to produce some large pitchers with more light,only time will tell.

LLeopardGGecko Posted April 13, 2006 Report Share Posted April 13, 2006 This usually happens to my Neps when they're moved to a new environment (like in the few weeks after I get them) or when I overwater. Quote Link to comment Share on other sites More sharing options...
Martin_mtl Posted April 13, 2006 Author Report Share Posted April 13, 2006 The plant was not subject to cold and was in it's current environement for several months (a terrarium). However, it had daily water misting on its leaves. I repoted it with NZ LFS and perlite, the roots seems OK. I also treated the whole plant with fungicide. The N. sibuyanensis is a fussy plant, I have less problems with other highlands such as N. lowii and N. diatas :o Quote Link to comment Share on other sites More sharing options...
D. Truesdell Posted April 13, 2006 Report Share Posted April 13, 2006 That should help alot. Was the soil compacted or really, uh slimey or starting to compress at all? Quote Link to comment Share on other sites More sharing options...
Martin_mtl Posted April 17, 2006 Author Report Share Posted April 17, 2006 Hi D. Truesdell, the soil was coco peat mixed with perlite. It didnt look too compacted to me, but then again I have lost several Nepenthes due to inadequate soil. I was begining to question the coco peat quality, but I have a N. diatas in the same mix doing fine... For highland Nepenthes, I will try to stick with LFS combined with some coarse materials from now on. Quote Link to comment Share on other sites More sharing options...
tonyc Posted April 17, 2006 Report Share Posted April 17, 2006 My two sibuyanensis are still babies, but I can't say I've ever found them particularly fussy: the one on the right in pure lfs as per most of my Neps and the one on the left in orchid bark (moss seemed to be out-of-season when I received it). The one in lfs is definitely doing better, though. Cheers, T. Quote Link to comment Share on other sites More sharing options...

Guest Andreas Eils Posted April 18, 2006 Report Share Posted April 18, 2006 Hmm, I add about 20 to 25% of coconut fibre to my Nepenthes soil (and also to Heliamphora soil), but doubt that it would be good to use it as a main component. :-k My two sibuyanensis are still babies... What are they? They´re already adolescent I would say! Cheers, Andreas Quote Link to comment Share on other sites More sharing options...
