The way I have done this for several now and it has worked out ok. I plant all the seeds in each pod in a gallon pot and plant them outside the first week of September. (I live in zone 8b) By the time the weather gets cold the plants have gotten big enough to survive just like any mature Daylily. Then I separate them after that. (The following Spring.). When I plant the seeds I also write the number of seeds I plant along with the cross...pod parent and pollen parent. I cover everything with pine straw over the winter.
