Question
The very first plant that I bought was from a local nursery, and it looks like there are either two or three Nepenthes in a pot that is about 12" in diameter.

Should I report them into single pots?

Answer
Hi John,

Only if you really want single plants.  Otherwise they look nicer together, and Nepenthes don't mind being a bit potbound.  They should be able to stay in a 12" pot for a couple of years at least.

Good Growing!
