Question

The Plant  

Room w/ Window   Hey Experts,
I'mm sure you get this question a lot but I just need to ask in my specifics. I have a beautiful nepenthes plant that is growing large leaves with small pitcher starts at the ends that never form into pitchers. When I bought the plant it had pitchers which died and shriveled away. I moved it to the location below which is a south/west window which receives direct sun and lots of ambient sunlight throughout the day. I keep the soil moist (peat, spaghnum moss, and orchid bark. I did recently re-pot the plant into the large pot seen in the picture.

What is going wrong here?

Hi Miles,

This looks like a Nepenthes x "Miranda".  Mirandas need lots of sun to be able to pitcher.  They also like warm temperatures.  When they are getting enough sun they usually have a slight reddish color to their leaves, and yours looks pretty green.  A recent transplant can also interfere with pitchering.  Also, if your windows are UV blocking glass I find this can be a factor too.  They often need some ultraviolet light to make the pitchers.  It's just a very energy intensive business to grow those.  If you have a window with more sun that will help.  You could also hang the plant outside partially shaded by a tree for the rest of the summer.  We do that all the time, and I've had some beautiful Mirandas outdoors in warmer summers.

Good Growing!
