Good!

The drainage may consist of any coarse material, such as old broken pots, small stones, pieces of charcoal, and the like, over which should be placed small broken sod or a littlemoss to keep the dirt from washing through and eventually stopping up the crevices through which the excess water should flow.

A safe rule to follow in first potting the majority of house-plants, is to use one-third turf-loam, one-third leaf-mold or decayed leaves, and one-third sand, thoroughly mixed. Reduce the amount of leaf-mold and sand at successive pottings, adding a little well rotted manure, until, when the plants have been potted in 6-inch pots, at least four-fifths of the soil is turfy loam. Press the soil firmly in the pot and around the plant. Never fill the pot level full of soil, else the plant cannot be watered.

Prickly Poppies, orArgemones, are hardy annuals, with large, bluish striking foliage and yellow flowers. They are easily grown in a warm soil and sunny exposure. Sow the seeds where the plants are to stand. Thin to 12 to 18 inches apart. They grow 2 feet high.

Primulas, orPrimroses, are of various kinds. One of them is the Auricula (which see). Others are hardy border plants. The true or English cowslip is one of these; also the plants commonly known as Polyanthus. Hardy Primulas grow 6 to 10 inches high, sending up trusses of yellow and red flowers in early spring. Propagated by division, or by seed sown a year before the plants are wanted. Give them rich, moist soil.

The Primula of the winter-garden is mostly theP. Sinensis(Chinese Primrose), grown very extensively by florists as a Christmas plant. With the exception of the full double varieties, it is usually grown from seed. The seed sown in March or April will make large flowering plants by November or December, if the young plants are shifted to larger pots as needed. The seed should be sown on the flatsurface of the soil, composed of equal parts loam, leaf-mold and sand. The seed should be pressed down lightly and the soil watered carefully to prevent the seed from being washed into the soil. Very fine sphagnum moss may be sifted over the seed, or the box set in a moist place, where the soil will remain wet until the seeds germinate. When the plants are large enough they should be potted separately or pricked out into shallow boxes. Frequent pottings or transplantings should be given until September, when they should be in the pots in which they are to bloom. The two essentials to successful growth through the hot summer are shade and moisture. Height 6 to 8 inches. Bloom in winter and spring.

At present the “baby Primrose” (Primula Forbesi) is popular. It is treated in essentially the same way as the Sinensis. All Primulas are impatient of a dry atmosphere and fluctuating conditions.

Prunesare varieties of plums with firm, meaty flesh, and which readily make dried fruit. Some of the Prunes are commercially grown in the East, but they are sold in the green state as other plums are; and they are adapted to all the uses of other plums. Prunes are cultivated like other plums.

Pruning.There are two general types of inquiry connected with the question of Pruning: First, that which has to do with the healing of the wounds; and second, that which has to do with the shaping of the top and the general welfare of the tree.

Before pruning

When a limb is cut off, it heals by being covered with callus tissue, which grows out from the cambium zone between the bark and wood and rolls over the face of thewound. The hard wood itself never heals; that is, the cells do not have the power of making new cells; therefore the old wood is simply covered up, or hermetically sealed as a cap is put on a fruit jar. It is evident, therefore, that no kind of dressing will hasten the healing of this wound. The merit of a dressing is to keep the wound sound and healthy until the callus naturally covers it over. All things considered, the best dressing is probably thick linseed-oil paint.

After pruning

So far as the wound is concerned, the best time for Pruning is ordinarily in the spring, when the vital activities are beginning; but the season also influences fruit-bearing and wood-making, and these questions should be considered. Those wounds heal best which are on strong main limbs, where there is a full flow of nutritious sap. The limb should be cut off so that the wound is parallel with the trunk upon which it sits, and close to it. That is to say, the longer the stub, the less rapid in general is the healing of the wound. It is the custom to cut the limb just outside the bulge at its base; but, in most cases, it is better to cut through this bulge, and to have the wound close to the main trunk.

Heavy Pruning of the top tends to the production of wood; therefore the severe Pruning of orchard trees, following three or four years of neglect, sets the trees into heavy wood-bearing, and makes them more vigorous. Such treatment generally tends away from fruit-bearing. This heavy Pruning is usually necessary in neglected orchards, however, to bring trees backinto shape and to revitalize them; but the best Pruning-treatment of an orchard is to Prune it a little every year. It should be so Pruned that the tops of the trees will be open, that no two limbs will interfere with each other, and so that the fruit itself will not be so abundant as to overload the tree. Pruning is a means of thinning. In general, it is best to prune orchard trees late in winter or early in spring. It is ordinarily better, however, to leave peaches and other tender fruits until after the buds have swollen, or even after the flowers have fallen, in order that one may determine how much they have been injured by the winter. Grapevines should be Pruned in winter or not later (in New York) than the first of March. If Pruned later than this, they may bleed. The above remarks will apply to other trees as well as to fruits.

It should be borne in mind that Pruning has two objects: one is to merely trim the tree or to make it assume some designed shape; the other is to make the tree more vigorous or more fruitful, or to make some other change in its character. These ideals are well illustrated in the Pruning of ornamental shrubs. If one wants to have the shrubs sheared into some particular shape, the shearing may be done at almost any time of the year; in fact, it is better to do it two or three times each year in order to keep the trees trim and neat. If, however, the desire is to secure more flowers, the case is a very different one. Some shrubs and trees bear their flowers on the wood of the preceding year. Such, for example, are the early flowering shrubs like lilacs and the snowballs. The flower buds are made the fall before. In this case, Pruningthe shrub in winter cuts off the flower buds. The ideal time for Pruning them, therefore, is just after the flowers have passed. The flower buds will form later in the season for the production of the flowers the following spring. Other shrubs, however (particularly those which blossom late in the season), bear on wood of the current year’s growth. That is, the clematis blossoms in late summer and fall on wood which grew that same season. The greater the quantity of strong wood which grows in any season, therefore, the greater the quantity of bloom in that season. With such shrubs, it is well to Prune in winter or early spring, and to Prune rather heavily. The abundance of new shoots which arise may be expected to bear flowers later on in the same season.

Following are some shrubs which, for best results in flower-bearing, may be Pruned when dormant (in winter): camellia, Jackmani type of clematis, cornus, hibiscus (shrubby), hydrangea, many loniceras or honeysuckles, philadelphus or mock-orange, some spireas.

Shrubs which may be Pruned when in leaf (just after blooming): lilac, deutzia, weigelas, exochorda, spring-flowering loniceras, tree peony, flowering almond, some spireas and viburnums, wistaria.

The marginal illustrations show how apple, pear and plum trees may be Pruned when received from the nursery. Cut back the roots to fresh, unbroken wood.

Various kinds of useful tree Pruners are shown in the margins.See alsoScraping.

Pyrethrum.The little, low-growing yellow-foliaged Feverfew, called Golden Feather, is used extensively for edging and design beds. Propagated by cuttings, as are geraniums.

The tall-growing species are very fine border plants, being easy to grow and having showy flowers, in colors ranging from white through lilac to crimson. Their flowers appear in June and last a month, when, if the plants are cut down, they will flower again in the fall. The Persian insect powder is made from the dried flower heads of some of these species. Propagated by seed or division. Hardy and fine.

Radishes (top)

Radishes (bottom)Spring Radishes

Spring Radishes

Radishesshould be grown quickly in order to have them at their best. They become tough and woody if grown slowly or allowed to stay in the ground too long. A light soil, well enriched, will grow most of the early varieties to table size in from three to five weeks. To have a supply through the early months, sowings should be made every two weeks. For summer, the large white or gray varieties are best. The winter varieties may be sown in September, harvested before severe frosts, and stored in sand in a cool cellar. When they are to be used, if thrown into cold water for a short time they will regain their crispness. Sow Radishes thickly in drills, 12 to 18 inches apart. Thin as needed.

Raspberry.Both the red and black Raspberries are essentials of a good garden. A few plants of each will produce a supply of berries for a family through six or eight weeks, provided both early and late varieties are planted. A cool situation, soil that will hold moisture without being wet, and a thorough preparation of the ground, are the conditions necessary to success. The black-cap Raspberries should be set 3 to 4 feet apart, the rows 6or 7 feet; the red varieties 3 feet apart, the rows 5 feet apart. Spring setting is usually preferable.

As with blackberries and dewberries, Raspberries bear on last year’s canes, and these canes bear but once. Therefore cut out the old canes after fruiting, or before the following spring, thus destroying such insects and fungi as may have lodged on them. New canes should have grown in the meantime, 3 to 6 to a hill.

Black Raspberries

The first year after the plants are set the canes should be pinched back when they reach the height of from 30 to 36 inches. If a very vigorous growth has been made the first season two canes may be left for fruiting, but in the case of weak growth, only one cane should be allowed to fruit. In case of low-growing varieties—those that have been pinched back short—a mulch of straw or grass around the plants at fruiting time will help to hold the moisture, and also serve to keep the fruits clean in case of heavy rains. A Raspberry plantation will last three to five years. The black varieties are propagated by layers, the tip of a cane being laid in the soil in midsummer; by fall the tip will have taken root and may be separated. The red varieties are propagated by suckers from the roots. In nurseries both blacks and reds are often propagated by means of root-cuttings.

For red rust, pull out the plant, root and branch, and burn it. Short rotations—fruiting the plants only two or three years—and burning the old canes and trimmings, will do much to keep Raspberry plantations healthy. Spraying will have some effect in combating anthracnose. Raspberries may be bent over to the ground so that the snow will protect them, in severe climates.

Varieties are always changing in favor. Good black-caps are Gregg, Ohio, and Kansas. Good red and purple sorts are Shaffer, Cuthbert, Loudon, and others.

Rhododendronsare broad-leaved evergreen shrubs which require a fibrous or peaty soil and protection from bleak winds and hot suns in winter. It is well to plant them amongst trees for protection. In the North, mulch heavily with leaves in the fall. See that the soil is made fibrous with leaf-mold or other material. Rhododendrons bloom from winter buds: therefore prune just after flowering, if at all.

Rhubarb, orPie Plant. This is usually propagated by division of the fleshy roots, small pieces of which will grow if separated from the old, established roots and planted in rich, mellow soil. Poor soil should be made rich by spading out at least 3 feet of the surface, filling with well rotted manure to within 1 foot of the level, throwing in the top soil and setting the roots with the crowns 4 inches below the surface, firming them with the feet. The stalks should not be cut for use until the second year, but the first, as well as the succeeding falls, some coarse manure should be thrown over the crowns, to be forked or spaded in lightly when spring opens.

In growing seedling Rhubarb, the seed may be sown in a coldframe in March or April, protected from freezing, and in two months the plants will be ready to set in rows, 12 inches apart. Give the plants good cultivation, and the following spring they may be set in a permanent place. At this time the plants should be set in well prepared ground, at a distance each way of from 4 to 5 feet, and treated as those set with pieces of roots.

If given good care and well manured, the plants will live for years and yield abundantly. Two dozen good roots will supply a large family.

Ricinus.SeeCastor Oil Plant.

Roses.It seems to be the first desire of the home maker, when he considers the planting of his grounds, to set out Roses. As a matter of fact, it should be one ofthe last things to do. Roses are essentially flower garden subjects, rather than lawn subjects. That is to say, the flowers are their chief beauty. They have very little to commend them in the way of foliage or habit, and they are inveterately attacked by insects and sometimes by fungi. In order to get the best results with Roses, they should be placed in a bed by themselves, where they can be tilled and pruned and well taken care of; and they should be grown as specimen plants, as other flower garden plants are. The ordinary garden Roses should rarely be grown in mixed borders of shrubbery.

Wild Roses

If it is desired to have Roses in mixed borders, then the single and informal types should be chosen. The best of all these isRosa rugosa. This has not only attractive flowers through the greater part of the season, but it also has very interesting foliage and a striking habit. The great profusion of bristles and spines gives it an individual and strong character. Even without the flowers, it is valuable to add character and cast to a foliage mass. The foliage is not attacked by insects or fungi, but remains green and glossy throughout the year. The fruit is also very large and showy, and persists on bushes well through the winter. Some of the wild Roses are also very excellent for mixing into foliage masses, but, as a rule, their foliage characteristics are rather weak, and they are liable to be attacked by thrips.

Probably the most extensively grown class of Roses is the Remontant or Hybrid Perpetual. These, while not constant bloomers, are so easy of culture and give such good returns for the care and labor, that their popularity grows each year. The list of good varieties is very extensive, and while a few, such as General Jacqueminot, Paul Neyron, Marshall P. Wilder, Victor Verdier, Anne de Diesbach, and Ulrich Brunner, are seen in most collections, onecannot go far wrong in planting any of the list. Two of the Hybrid Chinese Roses may go with the Remontants, having the same season of bloom and being about as hardy. These are Magna Charta and Mme. Plantier.

The next group in point of hardiness, and superior to the foregoing in continuity of bloom, are the Hybrid Noisettes, such as Coquette des Alpes, Coquette des Blanches, and Elise Boelle. The blooms of these are white, often tinted with pink, very double and fragrant.

The Hybrid Tea section, containing Duchess of Albany, La France, Meteor and Wootton, is very fine. These are not hardy in the North, but if protected by a frame, or if grown in pots, wintered in a pit, no class of Roses will give more general satisfaction.

The Bourbon section contains three of the best bedding Roses,—Apolline, Hermosa, and Souvenir de la Malmaison. These will bloom continually through the fall months until severe frost, and with a little protection will prove hardy.

The Bengal Roses, of which Agrippina is a leading variety, bloom through a long season, but are not hardy, and should be protected in a pit. They also make very fine pot-plants.

The Moss Roses are well known, and are desirable in a general collection.

The little Polyantha Roses, with Cecile Brunner and Clothilde Soupert as two of the best, are always attractive, either when planted out or grown in pots.

The climbing Roses, which bloom later in the season than the Remontants, are very useful as pillar and screen plants. The old Queen of the Prairies and Baltimore Belle are still in favor. A newer and better variety is the Crimson Rambler.

Hybrid Tea Rose

The Tea Roses have proved more disappointing to the amateur than any other. No one can resist the temptation to try to have a few of these highly perfumed, richly coloredRoses, but unless one has a conservatory or an especially favored location in the house, the results do not pay for the trouble. A few blooms may be had outdoors with plants set in the spring, but on the approach of winter they must be taken up and protected by more secure means than is taken with other Roses. If potted and grown in the house, they are the first plants to become infested with red spider; or if grown cool enough to escape that pest, they will be subject to an attack of mildew. Still, the results are well worth striving for, and a few persons will find the proper conditions; but the Tea Rose is essentially a florist’s flower.

All Roses are heavy feeders and require rich, moist soil. A clay soil, if well enriched and having perfect drainage, is ideal. Pruning should be carefully done, preferably in the spring. All weak growth should be cut out and the balance well cut back. The flowers of all Roses, except the Yellow Persian and the Harrison’s Yellow, being borne on the new wood, the bushes should be cut back half or more of their growth.

In the majority of cases, Roses on their own roots will prove more satisfactory than budded stock. On own-rooted stock, the suckers or shoots from below the surface of the soil will be of the same kind, whereas with budded Roses there is danger of the stock (usually Manetti or Dog Rose) starting into growth and, not being discovered, outgrowing the bud, taking possession, and finally killing out the weaker growth. Still, if the plants are set deep enough to prevent adventitious buds of the stock from starting, there is no question that finer Roses may be grown than from plants on their own roots.

The summer insects that trouble the Rose are best treated by a forceful spray of clear water. This should be done early in the day and again at evening. Those having city water or good spray pumps will find this an easy method of keeping Rose pests in check. Those withoutthese facilities may use whale oil soap, fir-tree oil, good soap suds, or Persian insect powder.

Roses in Winter.Although the growing of Roses under glass is a business which would better be left to florists, as already said, the following advice may be useful to those who have conservatories:

When growing forcing Roses for winter flowers, florists usually provide raised beds, in the best-lighted houses they have. The bottom of the bed or bench is left with cracks between the boards for drainage; the cracks are covered with inverted strips of sod, and the bench is then covered with four or five inches of fresh, fibrous loam. This is made from rotted sods, with decayed manure incorporated at the rate of about one part in four. Sod from any drained pasture-land makes good soil. The plants are set on the bed in the spring or early summer, from 12 to 18 inches apart, and are grown there all summer.

During the winter they are kept at a temperature of 58° to 60° at night, and from 5° to 10° warmer during the day. The heating pipes are often run under the benches, not because the Rose likes bottom heat, but to economize space and to assist in drying out the beds in case of their becoming too wet. The greatest care is required in watering, in guarding the temperature and in ventilation. Draughts result in checks to the growth and in mildewed foliage.

Dryness of the air, especially from fire heat, is followed by the appearance of the minute red spider on the leaves. The aphis, or green plant louse, appears under all conditions, and must be kept down by syringing with tobacco-tea or fumigation with tobacco stems.

A Hybrid Perpetual Rose

An effectual and preferable method now employed for destroying the aphis is to fumigate with the vapor arising from a pan containing a gallon of water and a pint of strong extract of tobacco. To generate the vapor, a piece of red-hot iron is dropped into the pan. From one to three or four pans are required to a house, according to its size. For thered spider, the chief means of control is syringing with either clear or soapy water. If the plants are intelligently ventilated and given, at all times, as much fresh air as possible, the red spider is less likely to appear. For mildew, which is easily recognized by its white, powdery appearance on the foliage, accompanied with more or less distortion of the leaves, the remedy is sulfur in some form or other. The flowers of sulfur may be dusted thinly over the foliage; enough merely to slightly whiten the foliage is sufficient. It may be dusted on from the hand in a broadcast way, or applied with a powder-bellows, which is a better and less wasteful method. Again, a paint composed of sulfur and linseed oil may be applied to a portion of one of the steam or hot-water heating pipes. The fumes arising from this are not agreeable to breathe, but fatal to mildew. Again, a little sulfur may be sprinkled here and there on the cooler parts of the greenhouse flue. Under no circumstances, however, ignite any sulfur in a greenhouse. The vapor of burning sulfur is death to plants.

Propagation.—The writer has known women who could root Roses with the greatest ease. They would simply break off a branch of the Rose, insert it in the flower-bed, cover it with a bell-jar, and in a few weeks they would have a strong plant. Again they would resort to layering; in which case a branch, notched half way through on the lower side, was bent to the ground and pegged down so that the notched portion was covered with a few inches of soil. The layered spot was watered from time to time. After three or four weeks roots were sent forth from the notch and the branch or buds began to grow, when it was known that the layer had formed roots.

Vase of Roses

Several years ago a friend took a cheese-box, filled it with sharp sand to the brim, supported it in a tub of water so that the lower half inch of the box was immersed. The sand was packed down, sprinkled, and single-joint Rose cuttings, with a bud and a leaf near the top, were inserted almost their whole length in the sand. This was in July, a hot month, when it is usually difficult to root any kind of cutting; moreover, the box stood on a southern slope, facing the hot sun, without a particle of shade. The only attention given the box was to keep the water high enough in the tub to touch the bottom of the cheese-box. In about three weeks he took out three or four dozen of as nicely rooted cuttings as could have been grown in the greenhouse.

The “saucer system,” in which cuttings are inserted in wet sand contained in a saucer an inch or two deep, to be exposed at all times to the full sunshine, is of a similar nature. The essentials are, to give the cuttings the “full sun” and to keep the sand saturated with water.

Whatever method is used, if cuttings are to be transplanted after rooting, it is important to pot them off in small pots as soon as they have a cluster of roots one-half inch or an inch long. Leaving them too long in the sand weakens the cutting.

Sageis a perennial, but best results are secured by resowing every two or three years. Give a warm, rich soil. Hardy.

Salpiglossis.Very fine half-hardy annuals. The flowers, which are borne in profusion, are of many colors, and rival in markings most other annuals. The flowers are short-lived if left on the plant, but will hold well if cut and placed in water. Seed should be sown inheat in February or March, the seedlings grown along until May, when they may be planted out. It is usually best to pinch out the centers of the plants at this time to cause them to branch.

Salsify

Salsify, orVegetable Oyster. Salsify is one of the best of winter and early spring vegetables, and should be grown in every garden. It may be cooked in several different ways. The seed should be sown as early in the spring as possible. Handle the same as parsnips in every way. The roots, like parsnips, are the better for the winter freeze, but part of the crop should be dug in the fall, and stored in soil or moss in a cellar for winter use.

Salvia coccinea

Salvia.TheScarlet Salvia(orSage) is a well known tender perennial, blooming late in the fall and making a fine effect in beds or borders. It is easily transplanted, and large plants removed to the house continue in bloom for some time. The blue and white species are both desirable summer flowering plants, and the low-growing Silver Leaf Sage is well adapted for edging. Propagated from seed, cuttings, or by division. Height 2 to 3 feet.

San José Scalehas now become a wide-spread pest. It has been introduced into the eastern states from the Pacific slope. It is a minute scale insect the size of a small pinhead, shield-shaped, with a raised center. There are various native and comparatively harmless scales which look very much like it, and an expert is usually needed to distinguish them. The San José Scale can usually be distinguished, however, by its very serious results. In favorable seasons it spreads with enormous rapidity, covering the branches of many kinds of plants, sapping their juices, and either killing or reducing them to such a low state of vitality as to renderthem useless; or they are killed by the winter. The indications are that the scale will never be so serious in the moist, cool climates of the northeastern states as it is in the hotter and drier climates of the West. It has been found by careful experiments that it can be killed by a spray of kerosene and water (seeKerosene) in a proportion of one part of kerosene to four or five of water. This material is applied with a mechanical pump mixer, and the application should be made on a sunny day so that evaporation soon takes place. Spraying with kerosene in cloudy weather is very likely to result in injury to the plants. Some experimenters have found crude petroleum to be a specific for the San José Scale.

It is not to be expected that the San José Scale can be exterminated any more than the tent caterpillar or apple scab can. It follows, therefore, that we should spray for the San José Scale as we do for other pests. It is such a serious pest, however, that the state or province should take measures to hold it in check. Some system of inspection should be inaugurated, and it is probably best that nursery stock be fumigated with hydrocyanic gas before it is sold. This gas is exceedingly poisonous, however, and should never be handled by the inexperienced. Whenever it is used, it should be under the control of experts. Plants or plantations which are badly infested with the scale would better be destroyed.

Scabiosa.Mourning Bride.A useful annual, producing a profusion of bloom through the greater part of the summer if not allowed to go to seed. The flowers range in color from white to rich purple, are borne on long stems, and are very lasting. The seed may be sown where the plants are wanted, or to hasten the season of bloom may be sown in boxes in February and grown along to be planted out in April.

Scarlet Runner.One of the pole or runningbeans (Phaseolus multiflorus). It is a great favorite with people from the Old World, especially English and Germans. This bean is used either as an ornamental vine for porches or trellises, or as a screen to hide unsightly objects. The red flowers are very showy, either on the plant or in bouquets. The green pods are excellent as string beans, and the dried beans are of superior quality. Seed should not be sown until the ground has become thoroughly warm; or the plants may be started in the house.

Scrapingof trees is rarely to be advised, except in fruit plantations. The old and hanging bark on apple and pear trees may be taken off in order to destroy the hiding places of insects and the breeding places of fungi, and also to make the plantation look more neat and kempt. Only the loose outer bark should be removed, however. Trees should not be scraped to the quick. If there is moss on trees, it can be destroyed readily by a spray of Bordeaux mixture.

A large part of the beauty of an ornamental tree lies in its characteristic bark, and it is very rare that such trees should be scraped.

Screens.SeeWindbreak.

Screw Pine.SeePandanus.

Sea-Kaleshoots are very highly prized as a delicacy when blanched. The seed should be sown in a hotbed early in the spring, plants transplanted to the garden when from 2 to 3 inches high, and given high cultivation through the season, being covered with litter on the approach of winter. The young stalks are blanched early the following spring by covering with large pots or boxes, or by banking with sand or other clean material. The Dwarf Green Scotch, Dwarf Brown, and Siberian are among the leading varieties. Sea-kale is eaten much as asparagus is. Highly prized by those who know it.

Sea-Kale is also propagated by cuttings of the roots 4 or5 inches long, planted directly in the soil in spring. The plant is perennial, and the early shoots may be bleached year after year.

Seed Sowing.The general rule in sowing seeds is to cover them twice or three times their thickness. This rule will apply to the majority of seeds, but in many plants of a naturally short season of bloom or growth, an instance of which is the sweet pea, it may be advisable to sow the seed deeper, that the roots may have sufficient moisture and be in a cool temperature through the hot summer months. Also, in sowing very minute seed, as tobacco, petunia, begonia, and others of like size, care should be taken to have them only under the surface of the soil,—simply pressed down with a smooth surface or allowed to settle into the soil with the soaking in of the water. The soil for all seeds should be loose and porous, in order to allow the excessive moisture to escape and the warmth to penetrate, but should be firmed directly over the seeds to induce an upward flow of moisture. One of the most common mistakes in sowing seed is in sowing all kinds at the same time without regard to the season, thus causing a failure with some, while others grow freely. All tender seed should be sown only when the ground has become thoroughly warm, while seeds of the so-called hardy plants may be sown as early in the spring as the ground is fit to work. A few kinds of seed are the better for soaking, especially such as for some reason have been delayed in sowing. Sweet pea seed is benefited by soaking if not put into the ground until the soil is warm. Seed of canna, moonflower and others with hard shells may be scraped until the outer shell is pierced or is very thin.

It is generally better to buy garden seeds than to grow them, for those who make a business of seed-growing become expert in the cultivation and selection of the plants.

Seedsof most plants should be kept dry andalso rather cool. It is always better to rely upon fresh seeds. Test them in boxes in the house, if possible, before planting them in the open. If beans, peas, corn or other Seeds become buggy, pour a little bisulfide of carbon (very inflammable) into them. The material will not injure the Seeds even if poured on them. It soon evaporates. A teaspoonful will kill the insects in four quarts of Seeds, if the receptacle is tight.

Most tree Seeds should be kept moist until planted. They are usually buried or kept in sand.

Sensitive Plant(Mimosa). This curious plant is often grown for the amusement it affords by its habit of closing its leaves and dropping the leaf-stalk whenever the plant is touched. Seed should be sown in heat early in the season, and the plants grown in pots or a protected border. The seed is sold by all seedsmen. The plant grows readily in a temperature suited to beans. It will not stand frost. The young plants are usually the most sensitive.

Shade Trees.The best Shade Trees are usually those which are native to the particular region, since they are hardy and adapted to the soil and other conditions. Elms, maples, basswoods, and the like, are nearly always reliable. In regions in which there are serious insect enemies or fungous diseases, the trees which are most likely to be attacked may be omitted. For instance, in parts of the East the elm leaf beetle is a very serious pest; and it is a good plan in such places to plant other trees than elms. Amongst the best exotic trees for shade in the northern parts of the country are the Norway maple, European lindens, horse chestnut, and the European species of elm. Trees for shade should ordinarily be given sufficient room that they may develop into full size and symmetrical heads. The trees may be planted as close as 10 or 15 feet apart for temporary effect; but as soon as they begin to crowd they should be thinned.

Shelter-belts.SeeWindbreak.

Shrubbery.Shrubs have two kinds of values or uses: first, they are useful for their own sakes or as individual specimens; and second, for use in the making of foliage masses or groups. Ordinarily they are used only for the former purpose in home grounds; but their greatest use is, nevertheless, in heavy masses about the borders of the place or in the angles of the building. That is to say, they should contribute to the general design of the place or to its pictorial effect. If they are planted in Shrubberies or masses, the flowers are still as interesting and as showy as they are when the bushes are planted alone. In fact, the flowers usually show to better advantage, since they have a heavy background of foliage. In the Shrubbery mass the bushes are more easily cared for than when they are scattered as single specimens over the lawn. The single specimen which is irregular, or ragged, or untidy, is an undesirable object; but such a specimen may contribute an indispensable part to the border mass. In the border they do not need the attention to pruning that they do in the lawn. The main part of the Shrubbery mass should be made of the stronger, larger growing and coarser Shrubs; and the more delicate ones, or those with highly colored leaves or showy flowers, may be placed near the inner edge of the plantation. Shrubs which are valued chiefly for their flowers or showy foliage, as, for example, theHydrangea paniculata, may be planted just in front of a bold Shrubbery mass, so that they will have a background to show off their beauties. Further directions for the lay-out of the grounds will be found under the articlesLawnsandBorders.

It is ordinarily best to plow or spade the entire area in which the Shrubs are to be set. For a year or two the ground should be tilled between the Shrubs, either by horse tools or by hoes and rakes. If the place looks bare, seeds ofquick-growing flowers may be scattered about the edges of the mass. The larger Shrubs, like lilacs and syringas, may be set about 4 feet apart; but the smaller ones should be set about, 2 feet apart if it is desired to secure an immediate effect. If after a few years the mass becomes too crowded, some of the specimens may be removed. Throw the Shrubs into an irregular plantation, not in rows, and make the inner edge of the mass more or less undulating and broken. It is a good practice to mulch the plantation each fall with light manure, leaf-mold or other material. Even though the Shrubs are perfectly hardy, this mulch greatly improves the land and promotes growth. After the Shrub borders have become two or three years old, the drifting leaves of fall will be caught therein and will be held as a mulch. It is often advisable not to remove these leaves, but to allow them to remain year after year, where they make a fine covering of leaf-mold. When the Shrubs are first planted, they are headed back one-half or more; but after they are established they are not to be pruned, but allowed to take their own way, and after a few years the outermost ones will droop and meet the greensward.

Good Shrubs are numerous. Some of the best are those to be found in woods and along roadsides. They are hardy. Of Shrubs which are generally adaptable for the North, the following are excellent:

Silene, orCatchfly. Some of the Silenes are hardy annuals of very easy culture. Sow seeds where the plants are to stand; or, if early results are desired, seeds may be started in boxes. The plants thrive in any garden soil, even if it is not very rich. Colors red, or sometimes running to white. One foot. Let plants stand 6 to 10 inches apart.

Smilaxof the florists is closely allied to asparagus. While it cannot be recommended for house culture,the ease with which it may be grown and the uses to which the festoons of leaves may be put, entitle it to a place in the conservatory or greenhouse. Seed sown in pots or boxes in January or February, the plants shifted as needed until planted on the bench in August, will grow fine strings of green by the holidays. The plants should be set on low benches, giving as much room as possible overhead. Green-colored strings should be used for the vines to climb on, the vines frequently syringed to keep down the red spider, which is very destructive to this plant, and liquid manure given as the vines grow. The soil should contain a good proportion of sand and be enriched with well-rotted manure. After the first strings are cut, a second growth fully as good as the first may be had by cleaning up the plants and top-dressing the soil with rotted manure. Slightly shading the house through August will add to the color of the leaves. The odor from a vine of Smilax thickly covered with the small flowers is very agreeable.

Snapdragon, orAntirrhinum. An old garden favorite, flowering freely through a long season. The dwarf strain is well adapted for bedding or borders. Any light soil, well enriched with rotted manure, will grow Snapdragons to perfection. Distinct varieties should be propagated by cuttings, as they do not come true from seed. Sow seed early in the spring.

Although bloom may be obtained the first year, late sown plants sometimes persist over winter and bloom early in the spring. Snapdragons make good window plants.

Snowdrop(Galanthus). This is one of the earliest flowers of spring, always welcome. It should be planted in the edge of the border. The bulbs may be planted in October in any good border soil and left undisturbed for years; or they may be potted at that time, and after forming roots be gently forced into bloom in winter.

Snowflake(Leucoium).Culture same as forSnowdrop.

Sodding.In general, the best way to secure a lawn is by the sowing of seed (seeLawn), since it is the least expensive way. For small areas, and along the sides of walks and drives, sods may be used. The results are quicker. Unless the sod is of the right kind, however, and very carefully laid, the results are not so good as with seed.
