    Actually, I've heard people attribute this sensitivity to N. merrilliana.
    However, I've not observed it in the specimens in my collection.

    Yes, Merrilliana has a frequnet problem with small pots, as it has a very long and narrow root system, sorta like 1 giant tap root only made up of like 50+ Nepenthes roots. The reason lots of people have trouble with Merrilliana is because they don't know that Merrilliana likes a very deep not wide pot to extend it's roots into. If not given this extra deepness it will not do well and cease pitcher production first, then leaves will form very wavy,stunted,and deformed as a sign it is very rootbound. I will transplant my Merrilliana about every 3 years, I check the roots and if they are coming in close proximity to the pot bottom I transplant, but it has proven very easy to grow with true lowland conditions and very high humidity and I reccomend planting in Long fiber spahgnum with lots of perlite and quit abit of orchid bark, it is a VERY airy and super fast drianing mix that my merrilliana love. But just keep it in a deep pot with long fiber sphangum, I don't like peat and perlite as it is too heavy and not light and airy enough for the roots. BUT you can use it with succes, long fiber spahgnum also makes VERY easy transplanting and virtually no rot distubance if you transplant carefully.

    Unhappy

    hmmmm......

    Doesn't merriliana live on lateritic hills in the phillippines? Isn't laterite very dense?

    This all seems so confusing...

    I think someone should write a "Nepenthes of the Phillippines" book. (fatboy!!! )

    Anyway, I'm thinking of experimenting with laterite in my merrilliana soil mix once it outgrows it's current 6 inch pot (which i think will be in the next few months). I've read descriptions of the stuff, and I think that it sounds alot like the clay stuff under the top soil in my backyard. I managed to get some of the clay out of the ground, and I'm wondering if any geology expert on the forum can tell me if it's really laterite or not. The best things in life are free, so I'm hoping that the stuff really is laterite!

    (I put the clay in wide tray and mixed it with a lot of water to try to "purify" it so that's why it's so wet.)


    I know that this is sort of off topic but merrilliana and bellii are related, so it really isn't THAT off topic. hehe

    Thanks a lot.

    But Joel, you must remember that is in the WILD not in cultivation. And if we grew Merrilliana in it's natural soil mix it wouldn't do so well as it isn't in it's natural conditions. That's why Nepenthes people have soil mixes, to see what works best on a certain plant in cultivation/captivity.

    Laterite simply means soil formed from the decomposition of rock. Most laterite type soils are very well drained as there are usually alot of rocks and pebbles still mixed into it since rock does not decompose uniformly. Clay is not the same. (clay is hydrated silicates of aluminum)

    I think there is a product on the market called laterite which is expanded and fired clay or ceramic, hence the confusion that laterite is a physical thing. Adding this type of product to your potting mix will give it a laterite feel.

    Is that a Nepenthes in your pocket or you just happy to see me?

    Ok.

    Laterite is not a physical thing while laterite soil is. Laterite is a deffinition to describe a soil that has formed by the breakdown of rock. I am not a geologist that's for sure. I do have some knowledge on soils but mostly I am just looking up what these terms mean in the dictionary. But to say I am going to add laterite to my potting mix is technically incorrect. You can say I am going to make a laterite type soil. Usually by adding alot of crushed stone. The kicker here is there are many types of stone and the key would be to get the the type of stone and grade that is the base material for the laterite soil the plant grows in naturally. Adding pea gravel to potting mix is essentially making a laterite type soil but it might not be the correct laterite soil and hence act differently than the soil the plant naturally grows in.
