As Hoon as the frost cuts the foliage down in the late autumn it is advisable to go over the quarters and cut off the stems about 6 in. from the surface. The old top can then be placed over the stool as a protection from further frost. The tubers are best left in the ground for at least a week after wards, to allow the sap to settle down in the buds and crown.
Before lifting, the labels should bo wired on the stems carefully. Tie-tubers can bo stored in any place where they are protected from the frost, and where the wind can blow through them and so dry them, for to store them away in a sodden condition means courting failure They must be well dried off before winter. After this they have very little rest as a general rule, for by the second week in December they should be ready for another year's work.
