No herbs are so easy to propagate by means of cuttings as spearmint,

peppermint, and their relatives which have underground stems. Every

joint of these stems will produce a new plant if placed in somewhat

moist soil. Often, however, this ability is a disadvantage, because the

plants are prone to spread and become a nuisance unless watched. Hence

such plants should be placed where they will not have their roots cut by

ols used close to them. When they seem to be extending, their borders

should be trimmed with a sharp spade pushed vertically full depth into

the soil and all the earth beyond the clump thus restricted should be

shaken out with a garden fork and the cut pieces of mint removed.

Further, the forked-over ground should be hoed every week during the

remainder of the season, to destroy lurking plantlets.

The other perennial and biennial herbs may be readily propagated by

means of stem cuttings or "slips," which are generally as easy to manage

as verbenas, geraniums and other "house plants." The cuttings may be

made of either fully ripened wood of the preceding or the current

season, or they may be of firm, not succulent green stems. After

trimming off all but a few of the upper leaves, which should be clipped

to reduce transpiration, the cuttings--never more than 4 or 5 inches

long--should be plunged nearly full depth in well-shaded, rather light,

porous, well-drained loam where they should remain undisturbed until

they show evidences of growth. Then they may be transplanted. While in

the cutting bed they must never be allowed to become dry. This is

especially true of greenwood cuttings made during the summer. These

should always have the coolest, shadiest corner in the garden. The

cuttings taken in the spring should be set in the garden as soon as

rooted; but the summer cuttings, especially if taken late, should

generally be left in their beds until the following spring. They may,

however, be removed for winter use to window boxes or the greenhouse


Often the plants grown in window boxes may supply the early cuttings,

which may be rooted in the house. Where a greenhouse is available, a

few plants may be transplanted in autumn either from the garden or from

the bed of summer cuttings just mentioned, kept in a rather cool

temperature during the winter and drawn upon for cuttings as the stems

become sufficiently mature. The rooting may take place in a regular

cutting bench, or it may occur in the soil out of doors, the plantlets

being transplanted to pots as soon as they have rooted well.

If a large number of plants is desired, a hotbed may be called into

requisition in early spring and the plants hardened off in cold frames

as the season advances. Hardening off is essential with all plants grown

under glass for outdoor planting, because unless the plants be inured to

outside temperatures before being placed in the open ground, they will

probably suffer a check, if they do not succumb wholly to the

unaccustomed conditions. If well managed they should be injured not at
