Happy birthday, Linda!
Timing is my biggest problem in seed starting. By late winter- early spring, space under my little light set-up is at a premium. I end up moving some cuttings to windows, have seeds under lights. Then I switch things around. My indoor seedlings are just always too early to maturity or too late. That's probably why I rely on wintersowing so much- I don't have to decide anything. I stick them outside and am usually happier with those than the indoor ones. The problem is me, though, not the method. And I usually don't do things that take really long, like lisianthus.
Last year my indoor impatiens were ready to plant out way too early. They were half dead by the time I could actually plant them out. I don't remember when I started those, either.
