Sorry for your losses of your hoped-for registrations.
What really gets me about that one seedling is the heroic efforts that I went through to save it. I was sure that I DID save that last fan, which I repotted, IN THE SHADE, with a mixture of planting mix, vermiculite, and fine redwood chips (we don't have pine fines here). Yet still, it died. And while it would never have been a registration, it was a hoped-for bridge plant to a polymerous daylily. (And the other seedling that died before I knew what was going on, was of course a polymerous one.
)
I have been trying to reconstruct what things I might have done wrong. Fertilizing in the summer? A change in fertilizers? (This year I have been using Miracle-Gro's all-purpose time release fertilizer, with some alfalfa meal and also some supplemental liquid fertilizing.I don't recall what I used last year, but prior to last year it was Osmocote.)
Right now I have seeds from that hoped-for bridge plant, and I am wondering if I should just chuck them...
