I have *attempted* to repot Cooper! I'd wanted to wait until I could get a potting mix from the local carnivorous plant nursery, but they've been out for a while and Cooper's medium was getting /nasty/. This is my first time repotting a nepenthes so I'll be keeping a close eye on its health for the next couple of weeks.
Coops has been *loving* the extra suna and warmer temperatures - we've been giving it outdoor time during the daylight hours and the colour of its leaves has developed wonderfully.
