Nepenthes Yellowing/Dying

[nikom123]

I recently purchased a Nepenthes Stenophylla online and after being planted for five days, its leaves have started to yellow and produce brown spots. I'm not really sure why so any help would be greatly appreciated!

Weather: Currently I keep it outside, and the high temperatures where I live have me worried. It has gotten as high as 95 degrees with about 50% humidity and at night it averages about 70 degrees with about 80% or above humidity. Also, it is in a position where it receives full sunlight from 10 am to 7 pm. However, it has rained here the past three days for portions of the day (around four hours) and has been partly cloudy, but it looks like it's clearing up for the next couple weeks.

Soil/Watering: I planted it in a 4-inch net pot with a layer of perlite on the bottom and gently wrapped sphagnum moss around the roots and to fill the pot. I also have a short tray that the pot rests on, and after it rained I noticed that the pot was sitting in water for a while, so I removed the tray for now. As for watering it, I pour distilled water on it whenever the soil feels dry and I have misted the leaves on days when it has been in full sunlight for long periods of time.

I think that the roots have gotten too much water so for now I'm going to let it dry more then I did previously before watering it again. I'd be grateful to hear of any other suggestions though.

To me it looks like sunburn. Most vendors don't grow their plants in full sunlight, so the plant is likely not used to it, and probably needed acclimation to higher light levels. Also, depending on where it came from, it may have needed acclimation to lower humidity as well. Also, N. stenophylla is a highland hybrid, so the temperatures you're receiving are definitely going to strain it. This is a plant that needs nighttime drops into the 50's F, and daytime temps pushing 85 may be dangerous even.

N.Stenophylla is Highland, but not a Hybrid. Few Nepenthes can be acclimated to full sun when grown outdoors, especially a plant as small as this. I would keep it in dappled light until large and then MAYBE give it morning or afternoon sun. Nepenthes grown in full light need higher levels of Humidity. Yes, a lot of Nepenthes do grow in full sun in habitat, but the humidity for those specific plants would be adequate in habitat.

Thanks for all the information! I actually moved it to a convenient shelf right under the glass table in the photo above. Now it receives the same hours of sunlight, but a more diluted form then before. Hopefully it gets healthy again soon

Oh, sorry, didn't notice that I'd written that. No, it's not a hybrid, that's just become an odd habit recently to write that.....
