No more care is required in transplanting herbs than in resetting other plants, but unless a few essentials are realized in practice the results are sure to be unsatisfactory. Of course, the ideal way is to grow the plants in small flower pots and when they have formed a ball of roots, to set them in the garden. The next best is to grow them in seed pans or flats (shallow boxes) in which they should be set several inches apart as soon as large enough to handle, and in which they should be allowed to grow for a few weeks, to form a ma.s.s of roots. When these plants are to be set in the garden they should be broken apart by hand with as little loss of roots as possible.

But where neither of these plans can be practiced, as in the growing of the plants in little nursery beds, either in hotbeds, cold frames or in the garden border, the plants should be "p.r.i.c.ked out," that is, transplanted while very small to a second nursery bed, in order to make them "stocky" or st.u.r.dy and better able to take care of themselves when removed to final quarters. If this be done there should be no need of clipping back the tops to balance an excessive loss of roots, a necessity in case the plants are not so treated, or in case they become large or lanky in the second bed.
In all cases it is best to transplant when the ground is moist, as it is immediately after being dug or plowed. But this cannot always be arranged, neither can one always count upon a shower to moisten the soil just after the plants have been set. If advantage can be taken of an approaching rainfall, it should be done, because this is the ideal time for transplanting. It is much better than immediately after, which is perhaps next best. Transplanting in cloudy weather and toward evening is better than in sunny weather and in the morning.
Since the weather is p.r.o.ne to be coy, if not fickle, the manual part of transplanting should always be properly done. The plants should always be taken up with as little loss of roots as possible, be kept exposed to the air as short a time as possible, and when set in the ground have the soil packed firmly about their roots, so firmly that the operator may think it is almost too firm. After setting, the surface soil should be made loose, so as to act as a mulch and prevent the loss of moisture from the packed lower layer. If the ground be dry a hole may be made beside the plant and filled with water--LOTS OF WATER--and when it has soaked away and the soil seems to be drying, the surface should be made smooth and loose as already mentioned. If possible such times should be avoided, because of the extra work entailed and the probable increased loss due to the unfavorable conditions.
IMPLEMENTS
When herbs are grown upon a commercial scale the implements needed will be the same as for general trucking--plows, harrows, weeder, etc.--to fit the soil for the hand tools. Much labor can be saved by using hand-wheel drills, cultivators, weeders and the other tools that have become so wonderfully popular within the past decade or two. Some typical kinds are shown in these pages. These implements are indispensable in keeping the surface soil loose and free from weeds, especially between the rows and even fairly close to the plants. In doing this they save an immense amount of labor and time, since they can be used with both hands and the muscles of the body with less exertion than the hoe and the rake require.
Nothing, however, can take the place of the hand tools for getting among and around the plants. The work that weeding entails is tiresome, but must be done if success is to crown ones efforts. While the plants are little some of the weeders may be used. Those with a blade or a series of blades are adapted for cutting weeds off close to the surface; those with p.r.o.ngs are useful only for making the soil loose closer to the plants than the rake dare be run by the average man. Hoes of various types are useful when the plants become somewhat larger or when one does not have the wheel cultivators. In all well-regulated gardens there should be a little liberal selection of the various wheel and hand tools.
Only one of the hand tools demands any special comment. Many gardeners like to use a dibble for transplanting. With this tool it is so easy to make a hole, and to press the soil against the plant dropped in that hole! But I believe that many of the failures in transplanting result from the improper use of this tool. Unless the dibble be properly operated the plant may be left suspended in a hole, the sides of which are more or less hard and impervious to the tiny, tender rootlets that strive to penetrate them. From my own observation of the use of this tool, I believe that the proper place for the dibble in the novices garden is in the attic, side by side with the "unloaded" shotgun, where it may be viewed with apprehension.
[Ill.u.s.tration: Wooden Dibbles]
In spite of this warning, if anyone is hardy enough to use a dibble, let him choose the flat style, not the round one. The proper way is to thrust the tool straight down, at right angles to the direction of the row, and press the soil back and forth with the flat side of the blade until a hole, say 2 or 3 inches across and 5 or 6 inches deep, has been formed. In the hole the plantlet should then be suspended so all the roots and a little of the stem beneath the surface will be covered when the soil is replaced. Replacing the soil is the important part of the operation. The dibble must now be thrust in the soil again, parallel and close to the hole, and the soil pushed over so the hole will be completely closed from bottom to top. Firming the soil completes the operation.
There is much less danger of leaving a hole with the flat than with the round dibble, which is almost sure to leave a hole beneath the plant. I remember having trouble with some lily plants which were not thriving.
Supposing that insects were at the roots, I carefully drew the earth away from one side, and found that the earth had not been brought up carefully beneath the bulbs and that the roots were hanging 4 or 5 inches beneath the bulbs in the hole left by the dibble and not properly closed by the careless gardener.
I therefore warn every dibble user to be sure to crowd over the soil well, especially at the lower end of the hole. For my own part, I rely upon my hands. Digits existed long before dibbles and they are much more reliable. What matter if some soil sticks to them; it is not unresponsive to the wooing of water!
LOCATION OF HERB GARDEN
In general, the most favorable exposure for an herb garden is toward the south, but lacking such an exposure should not deter one from planting herbs on a northern slope if this be the only site available. Indeed, such sites often prove remarkably good if other conditions are propitious and proper attention is given the plants. Similarly, a smooth, gently sloping surface is especially desirable, but even in gardens in which the ground is almost billowy the gardener may often take advantage of the irregularities by planting the moisture-loving plants in the hollows and those that like dry situations upon the ridges. Nothing like turning disadvantages to account!
No matter what the nature of the surface and the exposure, it is always advisable to give the herbs the most sunny spots in the garden, places where shade from trees, barns, other buildings and from fences cannot reach them. This is suggested because the development of the oils, upon which the flavoring of most of the herbs mainly depends, is best in full sunshine and the plants have more substance than when grown in the shade.

THE SOIL AND ITS PREPARATION
As to the kind of soil, Hobson"s choice ranks first! It is not necessary to move into the next county just to have an herb garden. This is one of the cases in which the gardener may well make the best of however bad a bargain he has.
But supposing that a selection be possible, a light sandy loam, underlaid by a porous subsoil so as to be well drained, should be given the preference, since it is warmed quickly, easily worked, and may be stirred early in the season and after a rain. Clay loams are less desirable upon every one of the points mentioned, and very sandy soils also. But if Hobson has one of these, there will be an excellent opportunity to cultivate philosophy as well as herbs. And the gardener may be agreeably surprised at the results obtained. No harm in trying!
Whatever the quality of the soil, it should not be very rich, because in such soils the growth is apt to be rank and the quant.i.ty of oil small in proportion to the leaf.a.ge.
The preparation of the soil should commence as soon as the gra.s.s in the neighborhood is seen to be sprouting. Well-decayed manure should be spread at the rate of not less than a bushel nor more than double that quant.i.ty to the square yard, and as soon as the soil is dry enough to crumble readily it should be dug or plowed as deeply as possible without bringing up the subsoil. This operation of turning over the soil should be thoroughly performed, the earth being pulverized as much as possible.
To accomplish this no hand tool surpa.s.ses the spading fork.
One other method is, however, superior especially when practiced upon the heavier soils--fall plowing or digging. In practicing this method care should be taken to plow late when the soil, moistened by autumn rains, will naturally come up in big lumps. These lumps must be left undisturbed during the winter for frost to act upon. All that will be necessary in the spring will be to rake or harrow the ground. The clods will crumble.
[Ill.u.s.tration: Surface Paring Cultivator]
I once had occasion to try this method upon about 25 acres of land which had been made by pumping mud from a river bottom upon a marsh thus converted into dry ground by the sedimentation. Three st.u.r.dy horses were needed to do the plowing. The earth turned up in chunks as large as a man"s body. Contrary to my plowman"s doubts and predictions, Jack Frost did a grand milling business that winter! Clods that could hardly be broken in the autumn with a sledge hammer crumbled down in the spring at the touch of a garden rake!
CULTIVATION
Having thoroughly fined the surface of the garden by harrowing and raking, the seeds may be sown or the plants transplanted as already noted. From this time forward the surface must be kept loose and open by surface cultivation every week or 10 days and after every shower that forms a crust, until the plants cover the whole ground. This frequent cultivation is not merely for the purpose of keeping the weeds in check; it is a necessary operation to keep the immediate surface layer powdery, in which condition it will act as a mulch to prevent the loss of water from the lower soil layers. When kept in perfect condition by frequent stirring the immediate surface should be powdery. Yes, _powdery_! Within 1 inch of the surface, however, the color will be darker from the presence of moisture. When supplied with such conditions, failures must be attributed to other causes than lack of water.
DOUBLE CROPPING
When desired, herbs may be used as secondary crops to follow such early vegetables as early cabbage and peas; or, if likely to be needed still earlier, after radishes, transplanted lettuce and onions grown from sets. These primary crops, having reached marketable size, are removed, the ground stirred and the herb plants transplanted from nursery beds or cold frames.
[Ill.u.s.tration: Thinning Scheme for Harvesting]
Often the princ.i.p.al herbs--sage, savory, marjoram and thyme--are set close together, both the rows and the plants in them being nearer than recommended further on. The object of such practice is to get several crops in the following way: When the plants in the rows commence to crowd one another each alternate plant is removed and sold or cured.
This may perhaps be done a second time. Then when the rows begin to crowd, each alternate row is removed and the remainder allowed to develop more fully. The chief advantages of this practice are not only that several crops may be gathered, but each plant, being supplied with plenty of room and light, will have fewer yellow or dead leaves than when crowded. In the diagram the numbers show which plants are removed first, second, third and last.
HERB RELATIONSHIPS
Those readers who delight to delve among pedigrees, genealogies and family connections, may perhaps be a little disappointed to learn that, in spite of the odorous nature of the herbs, there are none whose history reveals a skeleton in the closet. They are all harmless. Now and then, to be sure, there occur records of a seemingly compromising nature, such as the effects attributed to the eating or even the handling of celery; but such accounts, harrowing as they may appear, are insufficient to warrant a bar sinister. Indeed, not only is the ma.s.s of evidence in favor of the defendant, but it casts a reflection upon the credibility of the plaintiff, who may usually be shown to have indulged immoderately, to have been frightened by hallucinations or even to have arraigned the innocent for his own guilt. Certain it is that there is not one of the sweet herbs mentioned in this volumes that has not long enjoyed a more or less honored place in the cuisine of all the continents, and this in spite of the occasional tootings of some would-be detractor.
Like those cla.s.ses of society that cannot move with "the four hundred,"
the herbs are very exclusive, more exclusive indeed, than their superiors, the other vegetables. Very few members have they admitted that do not belong to two approved families, and such unrelated ones as do reach the charmed circles must first prove their worthiness and then hold their places by intrinsic merit.
[Ill.u.s.tration: Center Row Hand Cultivator]
These two coteries are known as the l.a.b.i.atae and the Umbelliferae, the former including the sages, mints and their connections; the latter the parsleys and their relatives. With the exception of tarragon, which belongs to the Compositae, parsley and a few of its relatives which have deserted their own ranks, all the important leaf herbs belong to the l.a.b.i.atae; and without a notable exception all the herbs whose seeds are used for flavoring belong to the Umbelliferae. Fennel-flower, which belongs to the natural order Ranunculaceae, or crowfoot family, is a candidate for admission to the seed sodality; costmary and southernwood of the Compositae seek membership with the leaf faction; rue of the Rutaceae and tansy of the Compositae, in spite of suspension for their boldness and ill-breeding, occasionally force their way back into the domain of the leaf herbs. Marigold, a composite, forms a clique by itself, the most exclusive club of all. It has admitted no members! And there seem to be no candidates.
The important members of the l.a.b.i.atae are:
Sage (_Salvia officinalis_, Linn.).
Savory (_Satureia hortensis_, Linn.).
Savory, winter (_Satureia montana_, Linn.).
Thyme (_Thymus vulgaris_, Linn.).
Marjoram (_Origanum Marjoram_; _O. Onites_, Linn.; and _M. vulgare_, Linn.).
Balm (_Melissa officinalis_, Linn.).
Basil (_Ocimum Basilic.u.m_, Linn., and _O. minimum_, Linn.).
Spearmint (_Mentha spicata_, Linn., or _M. viridis_, Linn.).
Peppermint (_Mentha Piperita_, Linn.).
Rosemary (_Rosmarinus officinalis_, Linn.).

Pennyroyal (_Mentha Pulegium_, Linn.).
h.o.r.ehound (_Marrubium vulgare_, Linn.).
Hyssop (_Hyssopus vulgaris_, Linn.).
