On Receipt of Cuttings
It is always best to plant (rooted) or stick (unrooted) garden mum cuttings immediately.
If the cuttings cannot be planted immediately, they may be stored for a day or two but they must be held in a cooler at 33° to 40°F. Before placing cuttings in the cooler, inspect them for damage from heating or freezing, breakage or dehydration. Holding cuttings in sheds, barns, etc., is not suggested and often leads to trouble.
