    lol! thanks guys! I try to give all my plants the best of conditions in my capacity. I am happy that they respond. I still have a very very stubborn talangensis which refuses to pitcher though.

    vraev- Congratulations on getting your N. rajah established and happy. But please allow me to share some friendly advice on this species.

    Between Jeremiah Harris and maybe a scant few other people or botanical gardens...I had one of the largest plants in the country. Probably not far from blooming size. As of last year it was over 2 feet tall and over 3 feet across. It was the crowning glory of my collection and now it is DEAD because I repotted it! When they get really large they HATE being disturbed so please make sure that you grow it in a large enough pot, with excellent drainage, and do not disturb it! I fortunately have several others coming along that I have made proper accomodations for that should suit them fine for a long time. But if you do have to repot a large plant just put everything into a new pot..soil and all and try not to disturb a SINGLE root if possible.

    A truly TERRIBLE lesson learned on my part.

    Ooh please do certainly pop in. Any advice or comments in helping myself and the others grow this species to such a size is always useful.

    THanks philcula. I am really sorry about the loss of your rajah. Even now I am soooo attached to this plant (and all my neps), that I can never bear loosing them. Loosing one of them might mean me giving up all my other plants and stay out of CP cultivation.
    I am growing mine in a 12 inch square basket. As the others here have once called it...lol!... a 12 inch laundry basket. lol.

    I wouldn't suppose this is enough for the king in the long run....so would you have any suggestions for a pot size? What pot size did u grow yours in and what pot size were you transferring it to?

    Also I mean its kind of strange.....young rajah's are hard to establish as they don't have a good root system...however, once the plant gets older..its a lot easier as the root system is larger. It seems as if once it gets a lot older....it reverts back to its delicate level. I guess by loosing the roots, the plant isn't able to SUPPORT the large growth it has and hence just drops it all...which makes perfect sense.

    You're right that a 12 inch square basket won't hold it for too long. My plant was growing in a 14 inch round pot..14 inches tall by 12 inches deep and was moved for permanent growth into a 5 gallon pot that had a 4 inch layer of drainage. I'm a HUGE advocate of putting styrofoam peanuts in the bottom of all my nep pots so the water just rushes out the bottom really fast. It was a solid mass of roots in pure LFS. PLEASE!!!! DO NOT USE PURE LFS ON THIS SPECIES. Yes, many people do and many are successful. But you CAN NOT keep this moss in good condition for the long term and it must be taken off the roots when it decomposes or you risk the loss of the root system anyways.

    So many growers out there swear by this stuff. But how many of them are growing their plants in 2, 3 or 5 gallon pots of this rubbish anyways? They grow their plants, for the most part, in smaller pots. Usually under 8 inches. And those who do grow in larger pots of pure LFS have not been growing their plants long enough to experience the utter destruction to ANY Nepenthes root system when trying to remove it or just leave the plant in its old medium for who knows how long. And it MUST be removed when it goes bad. I've seen many plants from people who make claims that their plants are doing great in this stuff and it hasn't been replaced in 5 years. You know what? I've been around the block a few times. Their plants ALL looked like terds! They really don't know what a truly healthy specimen should look like.

    Nepenthes rajah does NOT grow in pure LFS naturally and it experiences very good drainage where it does grow. It may be fine for smaller plants and even was good for my plant in its larger pot. But the moss was bad..smelled like it needed to be replaced, and in doing so I did some damage to the roots. I even did this under water to try to ease the moss away with a pair of forceps. Took me 2 hours to get as much of the moss away as I could and I still left quite a bit but the roots were completely tangled up in the stuff and I couldn't prevent hurting them. I had no choice.

    So I replanted it into a 5 gallon pot of my standard mix; the stuff I use that all my other N. rajah are thriving in. It immediately went downhill from there. I knew it was destined for death at that point but I refused to put it back into LFS.

    Please don't go that route. Trying to grow large neps in pure LFS in large pots and cleaning it off the roots when it is NECESSARY to do so can mean the ultimate destruction of your specimen.

    It makes me cringe when I see sooooooooooo many testimonials from folks who grow their neps in pure LFS. It's even more funny how really newbie they are...growing the plant for 8 months to a year is not experience. Nor is growing it in a 4-6 inch pot. Oh Please! Let's see what happens when your plant is grown from a 1 inch seedling and is eventually, in time, moved up and taken from its 12-14 inch pot or larger (of pure LFS) and is cleaned and repotted. I do not use LFS for growing any neps, ever. Nor do I top dress pots with it. I only use it..sparingly and mixed with other components, for rooting cuttings. I'm sure there are growers out there who ARE successful in managing plants under the same circumstances...but they are probably way more experienced than I.

    I appologize for my ranting. I was and still am completely traumatized that I killed my prized specimen. I could have prevented it.

    A-ha! I knew I was justified in hating LFS. I've also had my share of bad experiences (i.e. rot or being too dry) when using LFS, but obviously nothing anywhere close to as terrible as losing a specimen rajah.

    Out of curiosity Phil, what are you using now? I use aged fir/pine bark, charcoal, and perlite mostly for my HL/Intermediates. Some of them are also in bark/perlite/arcillite. LLs are in 5:2:2 peat/perlite/vermiculite. The mix containing arcillite is seeming to work rather well. I've got a vieillardi in it growing like gangbusters.

    I consider myself lucky enough to have seen Phil's plant in person before its demise. It was spellbinding!!! It has me panicked because my larger rajah is planted in a mix of mostly LFS, which its been in for years. This was one of the early plants I ever had, and I've since moved to mixes with little or no lfs, but this one is still in the old stuff. I'm terrified of re-potting it, and when I get the guts to do so, I'll will not try to clean the lfs from the roots, but rather just take the whole ball and plant it in the new container. When I get the guts to do it at all, that is.

    Incidentally, I have another rajah in a pure mulch mix that is growing faster - I'm a believer in the fast-draining mixes, as over time I'm seeing that all my great-growing plants are in fast-draining mixes.

    So, if you get a nep in pure LFS you should replant it when it is young?

    Ant,
    This is a problem that seems unique to N. rajah. Most of my plants accept replanting with no problems at all, though I rarely if ever try to extricate all the old media from the roots.
