The Brassicas have received too little attention from botanists. The inevitable outcome of such neglect or of any superficial study is a reduction of species, and in this direction Brassica has suffered greatly. The most perplexing species in our manuals are those which contain the greatest number of old types or synonymous names. It is true that this is supposed to be primarily due to the variation of the species or groups, but it is often to be charged to superficial study or insufficient material. Our manuals contain too few rather than too many species of Brassica; at all events, the miscellaneous dumping of rutabagas, turnips, rape and other plants into Brassica campestris is unnatural, and, therefore, unfortunate.
Cultivated tree Cherries have probably sprung from two European species, Prunus Avium and Prunus Cerasus. The domesticated forms of Prunus Avium are characterized by a tall, erect growth; reddish brown glossy bark, which separates in rings; flowers generally in clusters on lateral spurs, appearing with the limp, gradually taper-pointed leaves; fruit red, yellow, or black, generally sweet, spherical, heart-shaped, or pointed; flesh soft or firm. Sour Cherries are low-headed and spreading; flowers in clusters from lateral buds, appearing before the hard, stiff, rather abruptly pointed light or grayish green leaves.
Figs have been grown on the Pacific coast for much more than a century. Trees were probably at Loreto Mission, Lower California, before 1710, and reached the Alta California Missions soon after their establishment. Vancouver found Fig trees at Santa Clara in 1792. At the present time the Fig is cultivated in almost all parts of the state of California. The tree stands a range of temperature of from 18 degrees to 120 degrees Fahr., and the only portions of California really unsuited to its growth are certain cold or foggy districts. In the drier parts of the state it needs irrigation, as do other fruit trees. Some of the old Fig trees in California are of immense size. It is not uncommon to see trees with trunks of more than 2 feet in diameter. One tree in Stanislaus county is 60 feet in height, covers a circle 70 feet across, and has a trunk that girths 9 feet.
In England the fruit of many of the large, fine-flavored varieties is used uncooked. In America the fruit of the Gooseberry is thought of only in connection with pie (tart) or jam, and when transformed into these food products, flavor, while of some importance, is but a minor consideration. The claim that English Gooseberries are less palatable than the natives is quite true, when passed upon from this standpoint. The best cooking apples are not usually prized in the raw state on the table, and vice versa. The point is this — and it is worth making — that there are dessert Gooseberries and also culinary Gooseberries.
Notwithstanding the high esteem in which the nuts of several species of Hickory have been held since the settlement of America, but little progress has been made in their domestication and improvement. Out of the 9 or 10 species recognized by botanists, not more than 3 or 4 have been found sufficiently promising from an economic standpoint to justify conspicuous effort at amelioration. Of these the Pecan stands easily first, followed in order of apparent value by the Shagbark, the Shellbark and the Pignut.
Horse-radish, the well-known condiment used so much with roast beef and oysters, is a member of the natural family Crucifarae, to which belong cabbage, turnip, wallflower, stock, charlock, mustard, and many other vegetables, flowers and weeds. It comes to us from Great Britain, where it is thought to have been naturalized from some more eastern European country. It is often found growing wild in moist locations, such as the margins of streams, in cool woods and damp meadows, and, in some places, notably in the state of New York, is troublesome as a weed.
Indigo is mostly the product of I. tinctoria, of Asia, but it is also made from the West Indian species, I. Anil. Other species, even of other genera, also yield Indigo. These species were early introduced into the southern states for Indigo-making, and the product was once manufactured to a considerable extent. The plant was introduced into South Carolina in 1742 from the West Indies. When it was found that commercial Indigo could be made, the British Government offered a bounty. In 1775, the production was more than one million pounds of Indigo. The Indigo is not contained in the plant, but the dye is a product of manufacture from a glucoside indican which is contained in the herbage, and which is obtained as an extract.
Mangrove is a name applied to species of Rhizophora. The common Mangrove is one of the commonest plants in the swampy shores of tropical and subtropical seas. It is not in cultivation, but its strange methods of propagation make it one of the most interesting of plants.
Decaying vegetable matter, a uniform and rather low temperature, a uniform supply of moisture, – these are the general requisites for Mushroom-growing. The decaying matter is supplied by horse manure. The manure is allowed to heat and is turned several times before it is placed in the bed. The heating itself is probably of no advantage except as it contributes to the decay of the material: heat can be supplied by other means if necessary. The broken and decaying manure is placed a few inches or a foot deep in beds. When the temperature is reduced to 90 degrees or less the spawn is planted. As soon as the bed has cooled sufficiently, it is covered with earth or litter to regulate the temperature and moisture.
The Peach is a showy tree when in bloom. There are double-flowered varieties, which are as handsome as the dwarf flowering almond, and they are more showy because of the greater size of the tree. The flowers of the Peach are naturally variable in both size and color. Peach-growers are aware that there are small-flowered and large-flowered varieties. The character of the flower is as characteristic of the variety as size or color of fruit is.
This information appeared in L.H. Bailey’s Cyclopedia of American Agriculture from 1900. It was one approach to field design at a time when rotation was king. Though the menu of crop succession is important and useful, we find the sterile approach to field reshaping, in the name of “efficiency,” to be harsh and somewhat suspect. With the return of our small farms and good farming comes a renewed interest in the powerful tool of crop rotation. It preserves soil, builds soil, activates the calendar year in helpful ways and spreads the farmer’s risk.
There are three general divisions or kinds of graftage, between which, however, there are no decisive lines of separation: 1. Bud-grafting, or budding, in which a single bud is inserted under the bark on the surface of the wood of the stock. 2. Cion-grafting, or grafting proper, in which a detached twig, bearing one or more buds, is inserted into or on the stock. 3. Inarching, or grafting by approach, in which the cion remains attached to the parent plant until union takes place.
Budding is the operation of applying a single bud, bearing little or no wood, to the surface of the living wood of the stock. The bud is applied directly to the cambium layer of the stock. It is commonly inserted under the bark of the stock, but in flute-budding a piece of bark is entirely removed, and the bud is used to cover the wound. There is every gradation between budding and grafting proper.
Grafting is the operation of inserting a cion (or scion) — or a twig comprising one or more buds — into the stock, usually into an incision in the wood. It is variously divided or classified, but chiefly with reference to the position on the plant, and to the method in which the cion and stock are joined. In reference to position, there are four general classes: 1. Root-grafting, 2. Crown-grafting, 3. Stem-grafting, and 4. Top-grafting.
Veneer grafting makes no incision into old wood, and all wounded surfaces are completely covered by the matching of the cion and stock. It is not necessary, therefore, to wax over the wounds, as a rule. If used in the open, however, wax should be used. So far as the union of the parts is concerned, this is probably the most perfect form of grafting.
In making the resin and beeswax waxes, the materials are first broken up finely and melted together. When thoroughly melted, the liquid is poured into a pail or tub of cold water. It soon becomes hard enough to handle, and it is then pulled and worked until it becomes tough or “gets a grain,” at which stage it becomes the color of very light-colored manila paper. When wax is applied by hand, the hands must be well greased.
Squashes and pumpkins are very easy plants to grow, provided they are given a warm and quick soil. They are long-season plants, and therefore in the North they are very likely to be caught by frosts before the full crop has matured, unless the plants are started early and make a rapid and continuous growth early in the season. In hard, rough clay lands the plants do not get a foothold early enough to allow them to mature the crop. On such lands it is impossible, also, to plant the seeds early. As a consequence, nearly all Squashes are grown on soils of a loose and relatively light character.
The Strawberry is an herbaceous perennial. It naturally propagates itself by means of runners that form chiefly after the blooming season. These runner plants, either transplanted or allowed to remain where they form, will bear the following year. Usually the plants will continue to bear for five or six years, but the first and second crops are generally the best. It is therefore the custom to plow up Strawberry beds after they have borne from one to three crops. The better the land and the more intensive the cultivation, the shorter the rotation. In market-gardening areas and in some of the very best Strawberry regions, the plants are allowed to fruit but once. The plants therefore occupy the land only one year and the crop works into schemes of short rotation cropping.
An edible tuberous root, much prized in North America, a staple article of food in all the southern states, and also much consumed in the North. The Sweet Potato plant is a trailing vine of the morning-glory family. The branches root at the joints. The edible tubers are borne close together under the crown and unlike the common potato they do not bear definite “eyes.” The varieties differ greatly in length of vine and the “vineless” Sweet Potato has a bushy habit. Good commercial varieties that are well cared for rarely bloom, and even then the flowers may not produce seed. The plant is tender to frost. The species is widely distributed in tropical regions but is supposed to be of American origin.
It is always advisable to place coldframes and hotbeds in a protected place, and particularly to protect them from cold north winds. Buildings afford excellent protection, but the sun is sometimes too hot on the south side of large and light-colored buildings. One of the best means of protection is to plant a hedge of evergreens. It is always desirable, also, to place all the coldframes and hotbeds close together, for the purpose of economizing time and labor.
The garden Pea is the most important member of the genus Pisum. It is native to Europe, but has been cultivated from before the Christian Era for the rich seeds. The field or stock Pea differs little from the garden Pea except in its violet rather than white flowers and its small gray seeds. There are many varieties and several well-marked races of garden Peas. Whilst Peas are grown mostly for their seeds, there is a race in which the thick, soft green pods, with the inclosed seeds, are eaten.
Wheat is a plant of vast economic importance, widely distributed over the civilized world and having a history coincident with that of the human race. The grain is used largely for human food, chiefly as food-stuffs made from its flour, and in the form of breakfast food. The by-products of its manufacture are used as stock-food. The grain, whole or ground, is also valuable for stock feeding.
Grafting is one of the oldest of the arts of plant-craft. It is probable that the real art of grafting was held more or less as a professional or class secret in the ancient world, for the writers seem to have only the vaguest notion of its possibilities and limitations.
ZÈA (an old Greek name for some common cereal, probably spelt). The genus is founded upon the single polymorphous cultivated species Zea Mays, Maize or Indian Corn, whose origin is unknown but is suspected by some to be Teosinte. Most of the evidence points to Mexico as the region in which it originated and from which it spread. Under the head of Corn are given the botanical characters of the genus, a classification of subspecies of Zea Mays, and a discussion of Sweet Corn and Pop Corn.
