Dahlia jobs in December

Not much to do but do inspect the tubers removing any diseased or broken parts.  Dust with flowers of sulphur and cover the roots, not the stems, with dry soil or sand or peat or ashes.  Pot roots can now be cleaned and cut back.
Prepare the greenhouse in readiness for laying the tubers down to begin propagation.  As a commercial grower I start off in mid-January and advise anyone growing the 'giants' to do the same, they just seem to take longer to develop to mature plants for planting out
