Why is your name 'Nepenthes gracilis' if you are a highland expert and specialist, lol?
Do you have any pics of your rajah? I would like to see what it looks like growing in live sphagnum. Of the highlanders that grow on ultrabasic soil, this one is the most unlikely for that compost, from what I have been told. A rocky substrate is supposedly very suitable.
I don't grow ultra highlanders myself, so this is just what I have picked up from others. Otherwise, growing in live sphagnum is great for high humidity plants(tentaculata supposedly really loves it).
Would love to see a pic of rajah for comparison. So many people have different favorite composts, it seems there is no basic recipe for these plants. It depend on your growing conditions.
George :How do you e-mail purple sundew for live sphagnum?
