    I would be less concerned with what the soil is that it naturally grows in. Potting mix must be tailored to your own growing conditions. BUT as a starting point:
    It naturally grows in loose gravely ultramafic soil.

    I can't really say exactly what mix or blend of ingredients you should use. I have used 100% New Zealand sphag. I have also used a mix of peatmoss/perlite/laterite. I have also used a mix of fine coconut husk chips/Chopped NZ sphag/perlite.

    I can't say the plants have down better or worse in either mix. More critical to success as long as the potting mix is very well drained will be temperature and moisture levels.

    What the heck is ultramafic soil??? Tony you know the sphagnum that grows around here don't you? Could I use that? I have a Truncata growing in it and it seems to be doing fine. Nep.G.

    Mafic means: of or pertaining to rocks rich in iron, magnesium or other dark minerals. Ultra being Highly.
    SOO Ultramafic soil.. soil highly rich with rocks containing iron, magnesium etc... As opposed to soil containing sedimentary rock (sandstone, limestone etc)..

    Basically means a very gravelly soil but one which is pretty unaffected by the gravel since it is very dense and insoluable. The important thing here is that it is loose and drains FAST because of the high gravel content.

    I would imagine the Sphag would be fine as long as it is not over compressed.

    Ok I didn't know that term. Thanks Nep.G. One question is it nessasary to feed Rajah rats or small mamals such as mice. Or do you just feed it very large quantitys of insects. Nep.G.

    Hi Nepenthes gracilis,

    I Think you have the wrong imagination of growing N. rajah.
    You will NOT get huge pitchers. If you can provide your plnat with good conditions, than you will have 3 cm pitchers after 2 years and maybe 6 cm pitchers after 5 years.
    IF the conditions are good !

    So you don't need to hink about feeding them rats or something else.
    Johannes M. has the biggest N. rajah I have ever seen in cultivation. The plant is more than 10 years old and grew up under excellent conditions (Johannes has a greenhaous only for highland Neps) The plant flowered this spring and had no pitchers when I saw it. He showed us some dried old pitchers and they have been about 15cm in high.
    Getting huge pitchers will take many, many, many, ma.... years !!!!!!!!!!!!!!!!

    (in nature the plants are producing about 2-3 leafes in one year. the internodes are about 2-3cm, so some big plants are more than 100 years old !!!)

    I will let you know when I have a rajah that considers a mouse a nice midnight snack food. I suppose occasional feeding with pesky neighbor body parts wouldn't hurt either.

    On a serious note...no you don't need to feed it small mammals. My understanding is that although they can catch them in the wild, it is probably very occasional and purely by accident. I would also think that such a meal would most likely rot the pitcher. A slow steady diet of insects would be much more preferable. Providing the plant with a steady intake of nutrients for steady growth vs. the occasional huge meal.
