@kennysh they all look fine! We had two nights of 28 degree nights. I'm amazed and optimistic! Grew these in the 2" x 5" cell trays, they had much more root growth than any seedlings I've grown so far, so even if set back, they have the stores to recover. All the new growth looks just fine. I did, while planting, add a pretty thick ring of alfalfa pellets around each seedling, and then mulched. Maybe that helped?
