Here's a tip I'll share.
Once the rosette blooms are set, I now pull up the blooming rosette and move it to my "bloom" pot, which is a cracked 10 or 12" clay pot. The rosette continues to bloom and set seed, even though the roots have no substrate and the plants get neglected. I just stack the stalks together, so end up with a big pot of blooms and later, a lot of seed.
Getting the blooming hen out of the pot with the offsets remaining gives the offsets more space. Putting the bloomers together means easier pollination for the bees and more seed from the plants, all in a small space to make my job of collection easier. I'm hoping to have a lot of seed to share with members this year, later in the year.
