The last of these still in the ground are now putting on some luxuriant
topgrowth, presumably gearing themselves up to flower. Would it be
advisable to either cut off the foliage or lift them for storage
elsewhere?

I would expect the roots to be woody in the centre by now and then only fit
for the compost heap. BTW they freeze well if cut into bits.
