Carnivorous Plants/Nepenthes Soil Problem

Question
Hi Chris, all my nepenthes are doing great.  I grow them under two 40 watt cool white fluorescent tubes, have them on 14 hours a day, I water them with RO water, they get night time cooling, and they are all producing pitchers.

I've read that there are different types of soils that nepenthes can grow in, but I can't settle with an excellent mix.  It's starting to get me really, really confused now. Some of my nepenthes are growing in soil a little bit too wet, and my rajah I just repot is a little too course, but I'm just going to leave them all alone until they need to be repot again.

But when it comes to need of repoting, I'll definitely mess up on the soil again, and I don't want that to happen. From your experience, what is the best soil mix that nepenthes tend to like a lot?  I have Nepenthes Sanguinea, Mikei, Villosa, and Rajah of course.  Oh, and I've also seen people have live sphagnum growing around/or in the nepenthes, and they like to drop there pitchers in the bushy live sphagnum, and it looks gorgeous, and the plants look extremely happy and healthy. Even the sphagnum looks very happy.  How can I do all this for my nepenthes?

Answer
Hello Agustin,

I grow my Nepenthes in a pre-mixed soil that I obtain from cobraplant.com. It is composed of long fiber sphagnum moss, perlite, and orchid bark. It holds in some water, but provides a large amount of air pockets and great drainage. The problem is that it requires frequent watering as it will dry out rapidly.

I have a N. sanguinea and a N. truncata that both do very well in that mix.

I have never used live sphagnum, however; there would be no problem with using it as a top layer.

Expertise

I am capable of answering questions about the most common carnivorous plants found in cultivation. I have no personal experience with Byblis, Drosophyllum, Aldrovanda, and Heliamphora. I have not cultivated gemmae forming pygmy sundews nor tuberous sundews. For information regarding those aforementioned species, I would suggest contacting other experts. I can answer questions regarding most species of Nepenthes, tropical and temperate Drosera, Mexican Pinguicula, Sarracenias, and Dionaea. I have some limited experience with growing Utricularia, Cephalotus, and Darlingtonia.

Experience

I have grown carnivorous plants off and on for about 27 years. I have made the same mistakes and suffered the same mishaps that many growers make as they attempt to separate the myths from the realities of growing these plants. Currently, I am successfully growing a variety of tropical sundews, a Nepenthes, several Venus Flytraps of varying ages, and Sarracenias. I have been successful in stratifying Sarracenia seeds and providing artificial dormancy requirements for my temperate plants when needed.

Education/Credentials
I hold a Master's degree in Educational Psychology. Over my lifetime, I have constantly read books involving the growing conditions of carnivorous plants. I hope to incorporate the educational aspects involved in psychology with teaching other people how to cultivate carnivorous plants.
