I had asked
@Bonsai Nut to remove my entry from the contest. He suggested I close my entry with my experience. No seeds from Scheffields germinated. Why, I have no idea but I will not buy from them again. I bought a small amount of more seeds from treeseeds.com which germinated very well, same as they did last year. I went into the greenhouse yesterday to find that tray of seedlings decimated by what had to be mice. No other seedlings were touched, just the pines. Being now months behind I have no plans to buy more seeds.
My takeaway from this experience is where to buy and where not to buy my tree seeds and that my seed trays should've been covered despite being inside the greenhouse and up high off the ground. I see nothing wrong with my growing methods and can only assume the Scheffields seeds were too old. Especially since buying from another supplier and giving the same treatment to the seed gave me high germination.
