For what it's worth, here's another progression of three consecutive N. sabre pitchers: http://s138.photobucket.com/albums/q...t=faca549d.pbw
If someone out there reading this has a N. sabre of similar size (~12 inch leafspan) or N. red dragon (~13 inch leafspan) and doesn't fertilize, could you post your most recent pitchers for comparisons sake. Not exactly scientific, since we most likely have different growing temps, lights, etc.; but it might help. Maybe there are some other plants between us all that we could compare for posteriors sake?
