I had a fourth seed germinate, at least three weeks after the third one. The final four seeds were either non-viable or failed due to too much water. Seedlings two and three also died, though I am not exactly sure why. I tried to make sure their soil was not kept overly moist, and their cotyledons (neither developed actual leaves) started to discolor before their stems, so it was not damping off. I think they might be susceptible to leaf diseases relating to moist, still air (which is just about all the air there is in an Alabama summer), as I kept them in a covered area of my yard sheltered from wind, rain, and any creatures that might want to eat them. I have moved both remaining seedlings into a more exposed area for some air movement. The first seedling is doing well (it seemed unfazed by the same conditions that killed the two other seedlings) but still growing very slowly, with one perfect leaf and the beginning signs of two more. I have my fingers crossed that I have gotten lucky and that first seedling is monoecious.
