I haven't done it personally (I really haven't planted any seeds yet since I am still new to this daylily obsession); however, when my husband and I visited Daylily World (David Kirchoff and Mort Morss) David showed me their method. They plant the seeds directly in the ground. The seeds are put in a trough of sorts...seeds end up bunched together and even on top of each other with this method. They let the seeds grow over the winter and then in the spring they dig them up, tease them apart, and replant them with better spacing. My only question with this method (which I thought of after our visit so didn't ask him) was how they keep the crosses straight if all the seeds are just piled together in the ground?
