The gorse seeds in the trays have gone berserk. Last night there was only 1 thriving germinated seedling. This morning there were 6 more breaking through. By midday, 9. Just now this evening, 19.
In other news, I sowed the roses in a tray on a different windowsill. In a proper seed tray this time, following carefully the advice Prof. Google had to offer. There are still only 3 alder, but they're handsome wee seedlings. I'll plant them together, in the wettest bit of the West bed, above the French drain.
