These tubers and bulbs, as soon as the frost has partly injured the
foliage, should be taken up, and dried thoroughly, either in the sun or
a room where there is fire heat, taking care at all times to keep them
clear from frost. When they are dry, divest them of their foliage and
fibres. When perfectly dry, pack them in boxes with dry sand, or moss.
Store these away for the winter, either in a warm room or a dry cellar,
where they will at all times be exempt from frost, the least touch of
which would destroy them. We have kept them completely secure in the
cellar.
