Hi All,
What works for me regarding stratification of Sarracenia
& any CP seed for that matter: Wait until the seed pod
is dry; crumple it up, toss in a pill/vitamin bottle & stick
it the refrigerator for 6 to 12 weeks, making sure the
containers are air-tight, which can be accomplished
by putting them in a ziplock bag. After this, I just toss the
seed on the surface of a pot full of wet peat moss or
peat:perlite in a 2:1 mix, barely cover with a layer of damp
peat moss, set the pot in a tray of water and wait. (Season to taste..serves
one) This has always worked for me at
least, with excellent germination results.
Happy Holidays,
Doug
