These are callas, cannas, and dahlias that I over winter in their pots and soil
I am sure this is NOT the expert's way of saving these bulbs/tubers, but I know of no easier method.
Jut remove the foliage and stick the whole container in a cold, but not freezing place and leave it until spring.
I put these in hibernation last October...they have been 7 months in the dark without one drop of water.
See how dry the soil is?
Yet they are already coming up.
I will start watering and fertilizing them and I expect all to make a healthy return.
