I did not use a little greenhouse since this was just an experiment to see if they'd grow. All cuttings were taken during the summer and just stuck into a soilless mix and kept in half shade, half sun. They're in a tray that's in a typical watering tray.
When the mowing guys leave I'll empty a pot to take photos of the tubers, I hope!
If this works I won't have to face digging so many dahlias on what is usually a nasty late November day.
