I have some nepenthes in the house, which i have used for cuttings last september. The problem i am having is the cuttings turned black on the tips, even with cutting the black area off it still returned. They are all dead now. And to top it all off the plant i took the cuttings from is also going black at the growing point and stem. i cant remember the plant name but it has small pitchers 4cm high and is rapid growing.
Does any one know what is causing the black area.
