Scuipici Posted July 12, 2017 Report Share Posted July 12, 2017 3 of my nepenthes, ampullaria, bicalcarata and albomaginata are showing decay on the leaves. Bicalcarata is in the worst shape but it's still alive, it makes a leaf and then it rots. The ampullaria was doing the same but recently the tendril showed signs of decay and I lost it. Now the albomarginata is showing signs also. Had these lowlanders since last summer. The albomarginata was forming pitchers but the lids never opened up. The temp is around 20-23 during day, I keep them on a windowsill and the ventilation is not very great. Could it be some fungus problem? is the temp too low and they are finally giving up? is it a root problem? should i repot? I have a truncata on the same windowsill and it's doing ok.

Tropicat Posted July 25, 2017 Report Share Posted July 25, 2017 oh that doesnt look good. unfortunately im more into highlanders than lowlanders. I have lowland/hybrids that grow in my windowsill (which is actually 'highland' condition). They arent doing great, but still grow and make pitchers. Especially high humidity made it possible for me to grow them in cooler conditions. Brown spots sometimes come from leaf burn, but in that case the rest of the leaf is still a normal shape and firm. It might be rotten roots, im not sure. Your leaves seem to loose their strength. How wet is the soil? How do you water them? What is the humidity? I hope more experienced nep growers can help you!

Stefan Posted July 26, 2017 Report Share Posted July 26, 2017 I think 20°C is just not gonna do it for bicalcarata especially, the plant looks aweful. In habitat its roughly 25-40°C. Probably a lot of factors like: light, humidity and temperature. I would not repot it now, thats addictional stress that would kill the plant in such a state. Really wondering how it went ok for so long? 1 Quote Link to comment Share on other sites More sharing options...
Mujinamo Posted August 1, 2017 Report Share Posted August 1, 2017 Your media looks pretty dense. Are you using peat? I would repot them into a lighter mix (such as long-fibered sphagnum). 1 Quote Link to comment Share on other sites More sharing options...
Plantsman89 Posted August 8, 2017 Report Share Posted August 8, 2017 Try higher day time temperatures, as mentioned above :) What night time temperature do they get? It's worth noting that N. bicalcarata dislikes being root bound and when they're happy they increase in size rapidly. Quote Link to comment Share on other sites More sharing options...
werds Posted September 25, 2017 Report Share Posted September 25, 2017 How are they doing? 1 Quote Link to comment Share on other sites More sharing options...
ham Posted December 26, 2017 Report Share Posted December 26, 2017 keep temperatures above 25 degree celcius and humidity above 80%, they should grow and pitcher nicely. Low temperatures and humidity will cause the lowlanders to shrivel up Quote Link to comment Share on other sites More sharing options...
