Hi Jonna!
Thanks so much for that tip. I'm sure that I covered the seeds, since what I was reading online tonight said to cover them. I can't remember what site I looked it up on when I planted them, but many sites I viewed tonight said to cover them. Obviously, that didn't work, and I never thought to try them without covering them!
I really appreciate your help! I'm going to try again tomorrow, since I have a nice sunny window for them without it being direct light. I can always put them in the greenhouse over winter, if they don't get large enough to plant outside.
