I tried looking around and couldn't find too much on the topic. Basically I have 50+ Sarracenia flowers many of which are starting to open. While I plan on letting a few open-polinate, I would like to prevent this on several flowers so I can try and get pure species seed. I've read about bagging the flowers until they are mature and then hand pollinating, but I can't find too much on how to bag the flowers properly. Any tips?
