A dozen roots or more of this herb should be planted in some part of
the garden where it will not be disturbed by the plow, or if this
cannot be done readily, the roots can be taken up when the plowing is
done, divided and reset, which would probably raise a larger and finer
crop of leaves than allowing them to stand in the same place year
after year. The crop should be cut off a few inches above the ground,
as soon as it has made its growth and before it begins to bloom. The
shoots will again start to grow, and two or three crops can be cut in a
season; the cut tops can be tied in bunches and hung to the rafters, or
spread thinly on the floor of a cool loft or garret.
