Leaf and Root Cutting do not work very well on Sarracenia. If you have any chance at all you have to cut off a pitcher while its still flat, before it separates and gets hollow, and you must cut it off very low taking some of the rhizome with it. This is fairly hard to get to work. Humidity between 80% - 100% is important. After you cut it off cover the rhizome area in a rooting agent or soak in SuperThrive for 10 or 15 minutes then insert it into its preferred medium. I use Superthrive and 50/50 peat/perlite with a layer of Long Fiber Sphagnum as a topping. Superthrive isn't a rooting agent per say but it is an overall plant helper that I use almost exclusively. Its hard to come up with a way to keep humidity high enough unless you cut off a short pitcher. This isn't a reliable way for Sarracenia propagation for the most part in my opinion, at least for the beginner.
Sarracenia Division
All Sarracenia division should be done at the end of dormancy, either just before it starts to grow again or just after. This is the best way to expand your collection but you have to wait for the plant to cooperate. Eventually the rhizome will develop a new growing point. Wait until the new growing point has several roots then cut them apart using a sharp knife/razor blade. Soak the roots of both sections in SuperThrive and pot them both back up. Keep the humidity up until they have a chance to settle in. You are cutting the rhizome into pieces, not cutting the growths off of the rhizome.
You can help large Sarracenia rhizomes develop new growth points by cutting a wedge shape about half way into the rhizome as shown. With some luck each notch will develop a new growth point that can be divided next growing season. If you have plenty of root growth along a long old rhizome you can cut it into smaller two to three inch pieces. Each piece doesn't have to have shoot growth but each piece must have developed roots. Plant the pieces in a pot using the same type of medium as they were in. If you do TC use the wedge pieces to start cultures.
Seeds
I always recommend growing Sarracenia seeds in vitro. Either way Sarracenia seeds need a wet stratification period. Meaning they must experience a moist cold period before they will grow. You can achieve this one of two ways.
One way you can do this is place the Sarracenia seeds in a small zip lock bag with a moist piece of long fiber sphagnum moss for six weeks. You can also wrap them in a moist paper towel, place the paper towel in a plastic bag then place in the fridge. Any technique that results in a cold/moist environment will do the trick. I have also used baby food jars to place them in the fridge.
If you do not want to wait several weeks you can use Gibberellic acid. This is my preferred method but Gibberellic acid is generally hard to find and pricey when you do. There is a link to a place that sells Gibberellic acid in the links area if you are interested. I add a 1/4 "Smidgen" (smidgen measuring spoon) of Gibberellic acid to 2 oz of RO water and soak them in it for roughly 24 hrs. This will keep approximately 2 weeks if stored in the refrigerator. For mixing instructions see the Gibberellic acid information page.
Use something small to hold the Sarracenia seeds while they soak. Like baby food lids or pop bottle caps. Make sure you sterilize them before use. After the 24 hours I use a pipette to suck the acid out. I discard used liquids into a bowl with a couple paper towels until the process is complete. Then use a pipette to fill the container with the appropriate liquid then suck it out again at the appropriate time, and so on. Forceps can be used to pick up the completed seed to disperse into the culture jars.
