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

the fi
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.
