Soon I will be splitting my dahlias and potting them up in 1, 2 or 3 litre pots, depending on size of tuber. I use dry mpc and keep in greenhouse without watering until temps are clearly warming up. If it gets cold i cover with fleece. I then very lightly water and wait to see shoots. I increase watering, but still sparingly, until growth is really underway. This way I get large dahlias straining to go into garden in spring or into large pots.
