I posted a while ago about trying to germinate sandcherry seeds, and I regret to report that the experiment was not a success, at least not to any significant degree. Of the tray that I planted, two seeds did germinate (not counting the one that germinated in cold stratification and that I transplanted into its own pot), but all three seedlings died very quickly for reasons that I could not identify. There did not seem to be any damping off. The moisture in the soil seemed good. They had plenty of light and a steady temperature. I have no idea.
More positively, my wild roses and concord grapes have germinated beautifully, and my niagra grapes, planted a week later, are starting to show shoots as of this morning. I also have red currents, elderberries, and nannyberries planted now, with tomatoes going in this week, so the grow-op is in full production, and I am fully immersed in the romance of the seed.
