Spur (plant)

“ The shoot from the upper bud is cut away entirely. When this process is carried on from year to year, the spurs become longer and longer until they become unwieldy. Occasionally, however, happy chance permits the selection of a shoot on the old wood for a new spur. ”

“ When in flower the branches spread rigidly, but as the seed ripens the leaves begin to wither and drop off, the branches curl inward, and the plant becomes coiled up so as to resemble a small ball. In this state it is loosened from the soil and is drifted about with the sand over the arid plains. Should rain fall, or should it be blown into the water, the branches expand, the pods open, the seeds fall out, and it is a remarkable and newly-discovered fact that in the short space of twenty hours the seeds germinate and root. The plant will retain its susceptibility for years. ”

“ Those of the pine, fir, hemlock, and spruce are curved in such manner that, in being dragged through the air by the seeds, they are made to revolve, whirling the seeds in a close spiral, and sustaining them long enough to allow the winds to carry them to considerable distances,—a style of flying full of quick merry motion, strikingly contrasted to the sober dignified sailing of seeds on tufts of feathery pappus. Surely no merrier adventurers ever set out to seek their fortunes. ”

“ There are three modes of pruning and training the vine; but the best for vineries is what is called the spurring-in system. This consists in training the plant with one long main shoot, which is always suffered to remain, and shortening the strongest of the side shoots to one or two eyes every winter, and removing those that are weakly, or that grow too closely together, as the shoots left, which are called the spurs, should always be about twelve inches apart. ”

“ The leaves are scattered, large, often deeply divided, and of various highly developed forms. The undeveloped leaves are rolled up in the bud, having what is termed circinate venation. The sporangia are situated on the edge or on the lower side of the leaves, those on which the sporangia are borne (sporophylls) being often the ordinary foliage-leaves; but in a few cases the fertile differ from the barren ones (a higher stage in development) . The fertile leaves are not confined to definite parts of the shoot, and do not limit its growth. The archesporium is most frequently unicellular. ”

“ Press the ground firmly against the roots, but not on the bud. The soil just over this should be fine and mellow, so that the young shoot can push through easily, which it will soon do if the plants are in good condition. Except in the extreme South, spring is by far the best time for planting, and it should be done early, while the buds are dormant. After these begin to grow, keep the ground mellow and free from weeds. The first effort of the young plant will be to propagate itself. It will sprawl over the ground if left to its wild impulses, and will not make an upright bearing bush. ”

“ Starting high above the ground, these grow at an angle from the stem and generally reach the soil. They serve the twofold purpose of supporting the stem and of supplying it with sufficient air. If, by accident, the underground roots die off, the plant relies entirely on these air and prop roots for support and food. The strong prop roots are generally of the same diameter throughout, though sometimes they thicken at the ends. Normally they never branch above the ground, but after reaching the soil very often divide. ”

“ It is during this rainy period that they make their growth and produce their flower spikes. Both the foliage and bulbs being small, they require careful attention as regards moisture at the roots.
We find the most suitable material in which to grow them, is a little fibrous peat and sphagnum moss with good drainage, so that the water may pass away without becoming stagnant. Some portion of this material should be changed each year, just as the plant begins to show signs of making its growth. ”

“ In covering the seed pieces, whether they are planted flat or on ridges, it is well to leave a small, sharp ridge marking the line of the row. In some localities, however, where excessive moisture is not feared, the opening furrows are only partially filled after planting, leaving a depression along the row to be filled by the use of the smoothing harrow or other implement. ”

“ The year before the vines bear their first good crop, the spurs left should not exceed three or four, and each spur should not have more than two eyes, including the eye nearest the old wood, which eye is often overlooked and not counted in. The next year a few more spurs may be left, but at no time should each spur be allowed to carry more than two eyes. If more eyes are left, the lower eyes will not develop, and the only thing attained by such pruning is to increase the size of the head, and to place the leaves and the grapes farther away from the center of the vine. ”

“ It is a capital wind screen, and may be used to advantage on the exposed side of rockwork or flower beds, or as an ornamental shrub by the pond or lake side. The small dark-green leaves, the tiny white flowers, and great abundance of deep purple berries in winter, are all points that are in favour of the shrub for extended cultivation. The pretty, pinky shoots, too, help to make the plant attractive even in mid-winter. Propagation by layers or seed is readily brought about. To grow this shrub to perfection, peaty soil or decayed vegetable matter will be found most suitable. ”

“ It is by far the most majestic spruce I ever beheld in any forest, and one of the largest and longest lived of the giants that flourish throughout the main pine belt, often attaining a height of nearly 200 feet, and a diameter of six or seven. Where the growth is not too close, the strong, spreading branches come more than halfway down the trunk, and these are hung with innumerable slender, swaying sprays, that are handsomely feathered with the short leaves which radiate at right angles all around them. ”

“ Cherry shoots which are not required or desired for branch-forming can be transferred into fruit spurs, if the tree is of bearing age, by shortening them in. Do not, however, cut at an arbitrary distance of one inch from the starting point, but rather save one or two buds at whatever distance from the starting point these may be growing. If the tree is too young to bear, only growth shoots may appear from these buds, but they are likely to be short and will support fruit spurs later. ”

“ The cone-like fructification is about an inch in length and bears a number of peltate scales to which the spore capsules are attached. The spores are ready for dispersal in the month of May. Just about this time the barren stems put in an appearance. These rise to the height of two [114] feet, or even more, and have many whorls of spreading branches which in their turn may again be branched. It is these branches which carry on the real vegetative work of the plant. For the real leaves we must examine the sheaths, which with their wedge-shaped teeth are to be found at the stem joints. ”

“ It is a perennial low shrub, sometimes creeping near the ground, and at others growing more erect. The rootstock often creeps underground, a habit to which the plant owes its popular name, as it is said to be so tough as to wrest the harrow from the even tenor of its way. The more prostrate form is covered with viscid hairs; the more erect-growing plants are spiny. ”

“ If the plant is a large one, some of the leaves will probably bear spores. The spore-bearing leaves are at once distinguished by having the middle of each lobe of the leaflets folded over upon the lower side (F) . On lifting one of these flaps, numerous little rounded bodies (spore cases) are seen, whitish when young, but becoming brown as they ripen. ”

“ There are the twelve spruces, with short, sharp-pointed, four-cornered needles which grow singly all around the branches. They like cool places, and make their homes in great forests at the north or on mountains. The fir sisters and brothers have flat, blunt leaves growing on opposite sides of the branches, making them look like combs. The larches, who lose their needles in the fall; the cedars, the junipers, the arbor vitæ, the great California redwood—there are so many I can not name them all! They all belong to the cone bearing families. ”

“ Then if the growth be too vigorous, and there do not appear any indications of the formation of fruit spurs, as is often the case in the fertile soils of the West, our [158] impatient orchardists complain of the barrenness of their trees, and seek a remedy in root-pruning. This is generally performed with a sharp spade, with which a trench is dug in a circle around the tree. The excavation should be deep enough to reach all of the lateral roots ”

“ Flowers that make the tallest growth may be placed against the back with advantage—as Cobæa scandens, Ricinus, the Dolichos, Cosmos, and the like; giving them the advantage of the extra light and keeping them from withholding the light from the plants in front of them.
Coarse seeds should be planted in drills and covered to twice their depth. A furrow may be scratched with a sharp stick from an eighth to a half-inch deep, and the seed sown thinly in it, the earth being replaced and pressed firmly down with a piece of wood. ”

“ In the greenhouse, and even out-of-doors, under very favorable circumstances, plants may be grown from single buds; and green wood also propagates readily under glass. A vigorous young plant, with roots attached, may often be obtained by breaking off the suckers that start beneath the surface around the stems; and, by layering or bending bushes over and throwing dirt upon them, new plants are readily made also; but more shapely, and usually more vigorous, bushes are obtained by simple cuttings, as I have described. ”

“ When young the buds are a vivid red, changing to orange-yellow, and when fully expanded the flowers are creamy-white. It thrives in loam and peat to which a little dung has been added, and is well adapted for arbours, trellises, or stumps of trees. Sow the seed on a hotbed in March, harden off, and transplant when all fear of frost is over. Height, 8 ft. to 12 ft.
Mint.—May be grown in any garden soil. It is increased by runners, which, if not held in check, become very troublesome. The roots may be confined by means of tiles or slates. Flowers in July. ”

“ The root-pruning of pot-plants is necessary in the case of many soft-wooded subjects which are grown on year after year—pelargoniums and fuchsias, for example. After the close pruning of the branches to which they are annually subjected, and when the young shoots have shot forth an inch or two in length, they are turned out of their pots and have the old soil shaken away from their roots, the longest of which, to the extent of about half the existing quantity, are then cut clean away, and the plants repotted into small pots. ”

“ When a plant gets too tall for a room, and looks ungainly, make a slanting cut in the stem at the height desired, slip in a small wedge, and wrap the place with wet sphagnum moss, which must be then kept wet for several weeks. When you find a lot of new roots coming through this wrapping, cut off just below the mass and plant the whole ball in a pot with good soil. Keep in a shady place for a few days, and in a short time you will have two nice, well-shaped plants instead of the single straggly one. ”

“ The whole plant consists of a very long, much-branched, but undivided tubular filament. Where it is in contact with the substratum, root-like outgrowths are formed, not unlike those observed in Vaucheria. At first the walls are colorless, but later become dark smoky brown in color. A layer of colorless granular protoplasm lines the wall, becoming more abundant toward the growing tips of the branches. The spore cases, “sporangia,” arise at the ends of upright branches (Fig. 32, C) , which at first are cylindrical (a) , but later enlarge at the end (b) , and become cut off by a convex wall (c) . ”

“ After this stage spruce grows uniformly and rapidly, still somewhat slower than fir in height but exceeding it in diameter. The branches are slow to die, however, so that the tree remains bushy for most of its length until it reaches 60 or 80 feet in height, and even afterward a dense stand is required to clear it. In many pure spruce forests the larger trees have been able to withstand the pruning influences and remain limby, while the smaller ones, being pushed in height growth to reach sufficient light for survival, have cleared themselves with remarkable rapidity. ”

“ Requires wall protection, there being few situations in which it will succeed when planted in the open. It is a tall, climbing shrub, with dark green persistent leaves, and bearing purplish flowers in drooping racemes in mid-winter. Planted in rather dry soil, at the base of a sunny wall, this shrub forms a by no means unattractive covering, the twice ternate, glossy leaves being fresh and beautiful the winter through. ”

“ If the furrow has not been recently made, it will be well always to remove a portion of the surface, so as to have fresh soil next the roots. The tree being placed near the stake, the roots are carefully spread out in their natural direction, and the moist mellow earth is filled in among them, using the fingers when necessary, and gently shaking the tree so as to leave no empty cavities among the fibres. ”
