So are you planning on moving your tender trees indoors each fall/winter; or will you be growing them under lights entirely in your basement?
I actually started 26 different daylily seed crosses yesterday. Was planning on sowing a few Ginkgo seeds as well, giving them a cold stratification, but didn't manage to get that done. Maybe today. On the daylily seeds I'm testing some from 2013. They would be approximately 2 years + 4 months old.
I usually don't sow anything else this early, but need to start making list and checking.
