Question
I have a couple nepenthes ventricosa, I believe, and the plants are slowly turning from green to shades of yellow. I grow them in a cold frame greenhouse. High/low temps are mid 80s and lows to 60. They are growing in peat/orchid bark/sphagnum mix and are watered with RO water. I read online that moving the plants into more direct like will make them do this. Any ideas? Overwatering perhaps?

Thanks much for any insight you might have on this.

Answer
Hi Kirk,

Bright, warm conditions will make many Nepenthes more yellow.  This is pretty normal, especially for N. ventricosa.  If it's still producing pitchers nicely, it's probably fine.  If it indeed seems like too much sun, shade it slightly; put some other plants around it to dapple the light some.

Good Growing!
