Division of the clumps of such herbs as mint is often practiced, a sharp
spade or a lawn edger being used to cut the clump into pieces about 6
inches square. The squares are then placed in new quarters and packed
firmly in place with soil. This method is, however, the least
satisfactory of all mentioned, because it too frequently deprives the
plants of a large amount of roots, thus impairs the growth, and during
st season or two may result in unsymmetrical clumps. If done in
early spring before growth starts, least damage is done to the plants.
Artificial methods of propagation, especially those of cuttage and
layerage, have the further advantage over propagation by means of seeds,
in the perpetuation of desired characters of individual plants, one or
more of which may appear in any plantation. These, particularly if more
productive than the others, should always be utilized as stock, not
merely because their progeny artificially obtained are likely to retain
the character and thus probably increase the yield of the plantation,
but principally because they may form the nucleus of a choice strain.
Except in the respects mentioned, these methods of propagation are not
notably superior to propagation by means of good seed, which, by the
way, is not overabundant. By the consumption of a little extra time, any
desired number of plants may be obtained from seed. At any rate, seed is
what one must start with in nearly every case.
