Sound advice all round there. The fear of tuber rot. This is mainly due to the hollow stem of the plant. Interestinly also. This hollow stem is also the ideal highway for slugs and earwigs. Depending on each ones plans for their garden. If the plants have done well in a bed or border. Then why not leave them there? The bit about mildue etc. Unbeknown to many. When powdery mildue, as most call it appears on the cut stems etc of a plnt, and more so when the plant is naturally dying back. The mildew is a natural form of decomposition. In fact just as the upper part is dying back and rotting. The lower attachment to the tuber is also experiencing changes. It is in fact sealing itself off. This helps to naturally stop the decaying for want of better words, the chemical fluids etc form affecting the tubers. May I submit. If you intend to lift your tubers, The a few days in advance. Cut the plants down to say twelve inches from the ground. Leave them to the elements. Then when you do lift them, remove the soil and leave to dry in a well ventilated shed etc. Then whe dry, remove unwanted foliage but leave the main stem at abour four to six inches. Then store them in wood shavings or sawdust, after having dusted them with Flowers of Sulpur.
Otherwise. Why not leave them in situ. Let them die down and finally rfemove the debis. Then with bracken or straw apply a good top covering, so as to kee the frost out. Remember. Frost is the killer, not snow.
