Well! This year has been an unmitigated disaster for beans, and almost everything else for me, but my seed sown freesias are starting to show themselves in an unheated GH. I have ignored them, watered occasionally and several times thought that the tray should just be binned, but there they are, looking like broad blades of grass at the moment, but definitely doing something.
The moral of the story seems to be never to give up!
