The Practical Garden-Book Part 25

[Ill.u.s.tration: Strawberries]

STRAWBERRY. The saying that Strawberries will grow on almost any soil is misleading, although true. Some varieties of Strawberries will grow on certain soils better than other varieties. What these varieties are can only be determined by an actual test, but it is a safe rule to select such varieties as prove good in many localities. As to the methods of culture, so much depends on the size of the plot, the purpose for which the fruit is wanted, and the amount of care one is willing to give, that no set rule can be given for a garden in which but few plants are grown and extra care can be given. Large fruits and a number of them may be had by growing to the single plant, keeping off all runners and relying on numerous fruit-crowns on one plant for the crop of berries. Or Strawberries may be grown by the narrow matted-row system, in which the runners, before rooting, should be turned along the rows at a distance of from 4 to 6 inches from the parent plant. These runners should be the first ones made by the plant and should not be allowed to root themselves, but "set in." This is not a difficult operation; and if the runners are separated from the parent plant as soon as they become well established, the drain on that plant is not great. All other runners should be cut off as they start. The row should be about 12 inches wide at fruiting time. Each plant should have sufficient feeding ground, full sunlight, and a firm hold in the soil. This matted-row system is perhaps as good a method, either in a private garden or field culture, as could be practiced. With a little care in hoeing, weeding and cutting off runners, the beds seem to produce as large crops the second year as the first.

[Ill.u.s.tration: Well planted Strawberry]

The old way of growing a crop was to set the plants 10 to 12 inches apart, in rows 3 feet apart, and allow them to run and root at will, the results being a ma.s.s of small, crowded plants, each striving to obtain plant-food and none of them succeeding in getting enough. The last, or outside runners, having but the tips of their roots in the ground, are moved by the wind, heaved by the frost, or have the exposed roots dried out by the wind and sun.

[Ill.u.s.tration: Pot-grown Strawberry]

Ground rich in potash produces the firmest and best flavored berries.

Excessive use of stable manure, usually rich in nitrogen, should be avoided, as tending to make too rank growth of foliage and berries of a soft texture.

Except in the case of a skillful grower in a favored locality, the fall setting of plants is not to be recommended. The preparation of the soil and care of the plants more than overbalance the partial crop obtained the following spring.

In the single-plant or hill system the plants should be set 12 inches apart, in rows 3 feet apart. In the narrow matted row system the plants should be set 18 inches apart, in rows 3 feet apart. The first method requires about 14,000 plants per acre, the second about 8,000 plants.

The winter treatment of a Strawberry bed should consist in covering the plants, when the ground is frozen, in November or December, with straw or hay. Salt marsh hay, if obtainable, is the best, as no weed seeds are introduced. Cover the soil and the plants to the depth of 3 to 6 inches.

As soon as growth begins in spring, rake the mulch off, allowing it to lie between the rows; or, if the soil is hard or weedy, it may be taken off the patch entirely, the ground tilled, and then replaced for the purpose of holding moisture and keeping the berries clean.

Usually, Strawberries may be fruited twice or three times; but on rich soil, with extra good care, the first crop may be very heavy, and the patch may be plowed up thereafter. Some varieties do not produce pollen, and not more than two rows of these should be planted without a row of a pollen-bearing kind.

The rust and mildew may be held in check by Bordeaux mixture. It is usually sufficient to spray after the blooming season (or at any time the first year the plants are set), in order to secure healthy foliage for the next year.

SUNFLOWER (_Helianthus_). People who know only the coa.r.s.e annual Sunflower are not aware of the beauty which it is possible to secure with the herbaceous perennials belonging to that family. No border should be without a few of the hardy species. Their blooming period extends from early in August until heavy frost. The color runs from light lemon to the richest orange, and the range of growth from 3 to 10 feet, thus enabling one to scatter them through the border without any formal arrangement. They are of the easiest culture. Plants may be dug in the wild or bought of nurserymen. The domesticated double _Helianthus multiflorus_ is always valuable.

[Ill.u.s.tration: Wild Sunflower Plant]

Of the annual Sunflowers, there are some which are not generally cultivated that should receive more attention. The silver-leaved species from Texas (_H. argophyllus_), and the small, light lemon-yellow variety, are two of the best.

SWAINSONA. This makes a very desirable house plant, blooming through the late winter and early spring months. The blossoms, which resemble those of the pea, are borne in long racemes. The foliage is finely cut, resembling small locust leaves, and adds to the beauty of the plant, the whole effect being exceedingly graceful. It may be grown from seed or cuttings. Propagate a new stock each year. The flowers are large and pure white. The plant has been called the "Winter Sweet Pea," but the flowers are not fragrant.

SWAN RIVER DAISY (_Brachycome iberidifolia_) is a charming little border plant, growing to the height of 12 to 15 inches, and bearing quant.i.ties of blue or white flowers. The flowers last a long time when cut, and give a vase of flowers a light, graceful effect. The seed should be sown in boxes, hotbed, or windows; or, in warm garden soil, the seed may be sown where the plants are to stand. Only half hardy, and should not be planted out until settled weather. Annual.

SWEET CORN. See _Corn_.

SWEET HERBS. The Herb garden should find a place on all amateurs'

grounds. Herbs may readily be made profitable by disposing of the surplus to the green grocer and the druggist. The latter will often buy all that the housewife wishes to dispose of, as the general supply of medicinal herbs is grown by specialists, and goes into the hands of the wholesaler and is often old when received by the local dealer. The seedsmen's catalogues mention upwards of forty different Herbs, medicinal and culinary. The majority of them are perennial, and will grow for many years if well taken care of. However, it is better to resow every three or four years. The annual kinds are raised from seeds each year. Beds 4 feet square of each of the Herbs will supply an ordinary family.

SWEET PEA. No annual receives greater attention these days than the Sweet Pea. Sweet Pea exhibitions are held in several sections of the country, the press gives considerable s.p.a.ce to the discussion of varieties, and the public generally is interested in the growing or buying of the flower. On any occasion the Sweet Pea is in place. A bouquet of shaded colors, with a few sprays of galium or the perennial gypsophila, makes one of the choicest of table decorations. Deep, mellow soil, early planting and heavy mulching suit them admirably. Sow the seeds as soon as the ground is fit to work in the spring, making a drill 5 inches deep. Sow thickly and cover with 2 inches of soil. When the plants have made 2 or 3 inches growth above the soil, fill the drill nearly full, leaving a slight depression in which water may be caught.

After the soil is thoroughly soaked with water, a good mulch will hold the moisture. To have the ground ready in early spring, it is a good plan to trench the soil in the fall. The top of the soil then dries out very quickly in the spring and is left in good physical condition.

Frequent syringing with clear water will keep off the red spider that often destroys the foliage, and attention to picking the seed pods will lengthen the season of bloom. If the finest flowers are wanted, do not let the plants stand less than 8-12 inches apart.

[Ill.u.s.tration: Sweet Pea]

A succession of sowings may be made at intervals through May and June, and a fair fall crop obtained if care is taken to water and mulch; but the best results will be secured with the very early planting. In the middle and southern states, the seed may be planted in fall, particularly in lighter soils. It is easy to get soils too rich in nitrogen for Sweet Peas; in such case, they will run to vine at the expense of flowers. If the plants are watered, apply enough to soak the soil, and do not water frequently.

SWEET POTATOES are grown from sprouts planted on ridges or hills, not by planting the tubers, as with the common or Irish potato. The method of obtaining these sprouts is as follows: In April, tubers of Sweet Potatoes are planted in a partially spent hotbed by using the whole tuber (or if a large one, by cutting it in two through the long way), covering the tubers with 2 inches of light, well firmed soil. The sash should be put on the frames and only enough ventilation given to keep the Potatoes from decaying. In ten or twelve days the young sprouts should begin to appear, and the bed should be watered if dry. The sprouts when pulled from the tuber will be found to have rootlets at the lower end and along the stems. These sprouts should be about 3 to 5 inches long by the time the ground is warm enough to plant them out. The ridges or hills should be prepared by plowing out a furrow 4 to 6 inches deep. Scatter manure in the furrow and plow back the soil so as to raise the center at least 6 inches above the level of the soil. On this ridge the plants are set, placing the plants well in to the leaves, and about 12 to 18 inches apart in the rows, the rows being from 3 to 4 feet apart. The after cultivation consists in stirring the soil between the ridges; and as the vines begin to run they should be lifted frequently to prevent rooting at the joints. When the tips of the vines have been touched by frost the crop may be harvested, the tubers left to dry a few days, and stored in a dry, warm place. To keep Sweet Potatoes, store in layers in barrels or boxes in dry sand, and keep them in a dry room. See that all bruised or chilled potatoes are thrown out.

SYRINGING plants with water has two general offices: to clean the plants of pests or of dirt; to check evaporation or transpiration from the plant itself.

Gardeners look upon water as a good insecticide. That is, if it can be thrown upon the plants somewhat forcibly by means of a syringe or pump, or by the hydrant hose, it will wash off the insects and drown many of them. The water should be applied in a fine and somewhat forcible spray.

Care should be taken that the plant is not torn or bruised. The red spider is one of the most serious pests on house plants, and, in a dry season, on plants about the lawn. It thrives in a dry atmosphere. It usually lives on the under sides of the leaves. Syringing the plants frequently will destroy the pests. The thrips and slugs on rose bushes can nearly always be kept in check if one can spray or syringe his plants frequently. See _Spraying_.

Syringing to check transpiration from the foliage is very useful with plants which are recently transplanted. For instance, when carnations are taken from the field and placed in the house, it is well to syringe them occasionally until they have become established. The same is true with cuttings.

In Syringing plants, it is well to take care that the ground does not become too wet; otherwise the plant may suffer at its root. In the house, plants should rarely be syringed except when the weather is bright, so that they may soon dry off. The plant should not go into the night with wet foliage. Out of doors in hot weather, it is best to syringe toward nightfall. The foliage will ordinarily not suffer in such cases. With plants in the house, it is necessary to keep the leaves dry most of the time in order that fungi may not breed. This is true of carnations, which are very liable to attacks of the rust.

Plants are sometimes syringed or sprayed to protect them from frost. See _Frost_.

TERRACES may be desirable for two reasons: to hold a very steep slope; to afford an architectural base for a building.

It is rarely necessary to make a distinct Terrace in the lawn. Even if the lawn is very steep, it may be better to make a gradual slope than to cut the place in two with a Terrace. A Terrace makes a place look smaller. It is always difficult to make and to keep in repair. The surface is not readily cut with a lawn mower. Unless the sod is very dense, the upper corner tends to wash off with the rains and the foot tends to fill in. Nature does not have straight banks unless they are rock. The ill.u.s.tration in the margin shows how it is possible to treat a sloping lawn. In the distance is a distinct, sharp-angled Terrace; but in the foreground this Terrace has been carried out into the lawn, so that the slope is an agreeable one.

[Ill.u.s.tration: A slope is better than a terrace]

If it is necessary to Terrace a yard in order to hold it, the Terrace would better be at one side rather than in the middle. In that case, one is able to secure a good breadth of lawn. If the Terrace is at the outer side next the street, a perpendicular, mason-work, retaining wall may be constructed. If it is on the inner side of the lawn, it may be placed close to the building and be made to appear as a part of the architecture: it may be made the base of the building. If this is done, there should be a bal.u.s.trade around the edge of the Terrace to give it architectural feeling. The descent from the Terrace to the lawn may be made by means of steps, so as to add to the architectural aspect of the place. Terraces are most in place about buildings which have many strong horizontal lines; they do not lend themselves so well to buildings in the Gothic style. The general tendency is to make too many Terraces. The cases are relatively few in which they may not be dispensed with.

THINNING of fruit has four general uses: to cause the remaining fruit to grow larger; to increase the chances of annual crops; to save the vitality of the tree; to enable one to combat insects and diseases by destroying the injured fruit.

The Thinning of fruit is nearly always done soon after the fruit is thoroughly set. It is then possible to determine which of the fruits are likely to persist. Peaches are usually Thinned when they are the size of one's thumb. If Thinned before this time, they are so small that it is difficult to pick them off; and it is not so easy to see the work of the curculio and thereby to select the injured fruits. Similar remarks will apply to other fruits. The general tendency is, even with those who Thin their fruits, not to Thin enough. It is usually safer to take off what would seem to be too many than not to take off enough. The remaining specimens are better. Varieties which tend to overbear profit very greatly by Thinning. This is notably the case with many j.a.panese plums, which, if not Thinned, are very inferior.

Thinning may also be accomplished by pruning. If one knows where the fruit buds are, cutting them off will have the effect of removing the fruit. In the case of tender fruits, like peaches, however, it may not be advisable to Thin very heavily by means of pruning, since the fruit may be still further Thinned by the remaining days of winter, by late spring frost, or by the leaf-curl or other disease. However, the proper pruning of a peach tree in winter is, in part, a Thinning of the fruit.

The peach is borne on the wood of the previous season's growth. The best fruits are to be expected on the strongest and heaviest growth. It is the practice of peach-growers to remove all the weak and immature wood from the inside of the tree. This has the effect of Thinning out the inferior fruit and allowing the energy of the tree to be expended on the remainder. Apples are rarely Thinned; but in many cases, Thinning can be done with profit. On all home grounds, fruits should be Thinned whenever the trees are very full. In general, the best time to thin the fruit, as already said, is when the fruits have become large enough to be seen and handled. The discarded fruits should be burned if they contain insects or fungi.

THUNBERGIA. Tender climbers, making very pretty low screens. They are at their best when grown along the ground where the moisture keeps them free from the attacks of red spider. Some of the kinds are very fine vase or basket plants. All may be grown easily from seed. Annuals, 4 to 6 feet. Flowers white and yellow.

[Ill.u.s.tration: Thunbergia alata]

TILLAGE. By Tillage is meant the stirring of the soil. Tillage is the fundamental operation in agricultural practice. Most farmers till for three reasons: to get the seed into the land; to keep the weeds down; and to get the crop out of the land. The real reason for Tillage, however, is to ameliorate the land; that is, Tillage makes the soil mellow and fine, and an agreeable place in which plants may grow. It enables the soil to hold moisture, to present the greatest feeding surface to roots, to allow the circulation of air, and intensifies many chemical activities. Tilling the soil is the first means of making it productive. If one understands the many forces that are set at work, the Tilling of the soil becomes one of the most interesting and exciting of all agricultural operations.
