The Practical Garden-Book Part 17

If used when small (2 to 3 inches in diam.), and not allowed to become hard and tough, it is of superior quality. It should be more generally grown. The culture is very simple. A succession of sowings should be made from early spring until the middle of summer, in drills 18 inches to 2 feet apart, thinning the young plants to 6 or 8 inches in the rows.

It matures as quickly as turnips. One ounce of seed to 100 feet of drill.

[Ill.u.s.tration: Lantana]

LANTANA is a popular greenhouse pot-plant, and is occasionally seen in window-gardens, being grown for the profusion of its orange-red, heliotrope-shaped flowers. In the South, and sometimes in the North, it is planted out for the summer. It is very easy to grow, and also to propagate by means of cuttings. Although the flowers of the common species are ill-scented, the profusion of bloom makes it desirable.

LARKSPUR. DELPHINIUM. The Larkspurs are among the very best hardy plants, being free-flowering and having a good habit. They should be in every mixed border, particularly the perennial kinds. The tall flower-spikes, showing above the cut foliage, give the plant a striking effect. The flowers are in shades of blue in most varieties. The plants are propagated by division of root or from seed. The latter method will give good results, although the resulting plants are not likely to be the same variety as the seed plant.

As winter approaches, a covering of coa.r.s.e litter should be thrown over the crowns of the perennial kinds. The plants will come into bloom in late June and continue for a long season. Plants should be set 3 to 5 feet apart if in rows, but they are seen to better advantage when mixed with other border plants. Height of plants from 3 to 5 feet.

The annual Larkspur may be grown from seed sown in heat and transplanted to the ground in May; or seed may be sown where the plants are wanted and the seedlings thinned to 1 foot. These seedlings will bloom in June, and continue through the summer. Plants grow from 8 to 18 inches high.

LATHYRUS. See _Pea, Everlasting_; also, _Sweet Pea_.

LAWNS. In order to have a good Lawn, two things are essential: first, a pleasing surface or contour; second, a dense, firm sod.

Inasmuch as the Lawn is, or should be, a permanent thing, it is necessary that the greatest care be exercised to grade the land and to thoroughly prepare it before any seeds are sown. About a new building the filling should be allowed to settle, so that the finished surface will slope gradually away from the foundations and the steps. If the land is very hard clay, or if the place is rather low, it is always well to lay tile under-drains at frequent intervals. Everything should be done to cause the land to be deep and loose, so that the gra.s.s roots will run far into the soil and not be pressed for lack of moisture in a dry time. If the land has not had applications of manure in recent years, it is well to plow in, or to spade in, a liberal quant.i.ty of well-rotted litter from the barnyard. Work this into the soil as deeply as possible. If the hardpan is rather high, it is well to subsoil the area or to trench it (that is, to spade it up two or three spades deep).

If the land is apparently not fertile in plant-food, it is well to add a dressing of some commercial fertilizer to the surface when the gra.s.s seed is sown. This will start the gra.s.s quickly and allow it to get a foothold before the severe weather of midsummer comes.

[Ill.u.s.tration: It is fun to make a garden]

[Ill.u.s.tration: A garden corner]

The kind of gra.s.s seed to sow will depend upon the region and also upon the personal tastes of the owner. The one standard Lawn gra.s.s is June gra.s.s or blue gra.s.s (_Poa pratensis_). The seeds of this gra.s.s are sold in the hulls, and therefore the bushel weighs only fourteen pounds. Not less than two and one-half to three bushels should be sown to the acre.

In the southern states, June gra.s.s will not hold, and Bermuda gra.s.s is used, being sown about as thick as recommended for the June gra.s.s. There are various prepared Lawn gra.s.s mixtures which are excellent, but the June gra.s.s alone will give a very excellent Lawn in a short time.

Whether one shall sow white clover in his Lawn depends mostly upon his personal taste. If he likes the white clover, it is well to put in a quart or two of seed to the acre, sowing it separately from the June gra.s.s in order to get an even distribution. Some persons like to see the white clover in certain parts of the Lawn. It thrives very well where the land is rather moist. In parts of the East, Rhode Island bent gra.s.s is used for lawns.

[Ill.u.s.tration: A nursery]

The gra.s.s seed should be sown in the cool of the year. It may be sown in September and thereby become established before winter; or it may be sown very early in the spring. In newly made Lawns, it is a good plan to grade the area thoroughly in the fall, allowing it to settle in the winter; and then, if the surface remains even, to sow the gra.s.s seed on one of the latest snows in spring. By sowing it on the snow, one can see that it is distributed evenly; and when the snow melts, the seed is carried into the land and does not need covering. It is well to sow three or four quarts per acre of timothy seed, for the timothy germinates very quickly, and makes a green area the first season, but is killed out as soon as the June gra.s.s gains a foothold. Timothy will not stand the continued cutting, whereas the June gra.s.s will. The timothy, therefore, serves as a temporary covering to the land, indicating where the borders are, and thereby outlining the area for the Lawn mower to cut. The timothy seed should be sown separately from the June gra.s.s in order to insure even distribution. On hard lands it is well to sow two or three quarts per acre of crimson clover seed. The long roots of this plant tend to improve the physical condition of the soil; and when they decay, they leave nitrogen in the soil for the gra.s.s to use. Since crimson clover is an annual plant, it will not do any permanent mischief in the Lawn.

[Ill.u.s.tration: A lawn, with planting on the sides]

The first season the weeds will probably come up thickly, especially if the land is rich. These weeds should not be pulled, for whenever one is pulled out of the ground, many gra.s.s plants are rooted up and the surface is made uneven. The only way in which to keep down weeds is to mow them frequently with a Lawn mower. They will not appear in any great numbers the second year, unless there should be some perennial weeds, like dandelion or dock; and these may be pulled out the first fall or the following spring.

It is rare that one secures a perfectly good and uniform sod from one sowing of seed; especially is this true if the soil varies in different parts of the area. If the surface contour is satisfactory, it is unwise to dig up the areas on which the seed has not caught. It is best to rake them over with a steel rake in fall or spring, sowing on a little commercial fertilizer rather rich in nitrogen, and sow more seed. Nearly every Lawn will need patching in this way from year to year. If the Lawn is attended to in fall and spring by sowing gra.s.s seed, the weeds will rarely do serious mischief. When weeds are troublesome on the Lawn, it means that there is not sufficient gra.s.s, and every effort should be made to get more gra.s.s. Therefore, when the perennial weeds are pulled out, sow more gra.s.s seed.

[Ill.u.s.tration: A picturesque rill on the lawn]

When narrow-leaved plantain bothers, it is an indication that the land is too poor and dry for gra.s.s. In such cases, the land usually lacks humus or vegetable matter; and in various severe incursions of the plantain, it may be necessary to spade up the weedy areas and to work rotted manure into the soil. Usually, however, the plantain can be killed out by enriching the soil and sowing more gra.s.s seed. The common practice of sprinkling Lawns is nearly always pernicious, since the water is not supplied in sufficient amount to wet down very far, and the gra.s.s tends to make surface roots. When the watering is omitted the plants suffer. The more a Lawn is sprinkled, the more the gra.s.s depends upon the sprinkling. If it is necessary to water the Lawn, the water should be allowed to run directly from the hose until the surface area is completely soaked. It is best to do this at nightfall. When the water is applied by means of a sprinkler, a large part of it evaporates and does no good to the ground. The fundamental treatment of the Lawn is to have the land so deep and porous that the gra.s.s roots strike deep into the soil and do not need the surface water. A Lawn which is well made will need watering only in unusually dry times.

Mow the Lawn frequently when it is growing rapidly,--in spring and early summer. In the fall mow less frequently, and let it go into the winter with a long coat of gra.s.s. If the Lawn is mown as often as is needed, it will not be necessary to rake off the tr.i.m.m.i.n.gs. In fall, top-dress the Lawn with commercial fertilizer at the rate of 500 pounds to the acre.

If the Lawn has not been raked clean of all the tr.i.m.m.i.n.gs and decayed refuse which covers the surface of the ground, it is not necessary to dress it with stable manure; for manure is unsightly, unsavory, and often brings in weeds. Many persons make the mistake of raking the Lawn clean in late fall.

Closely a.s.sociated with the making of the Lawn is the general arrangement of the planting. It is the common fault to scatter the planting. Much better effects are secured by ma.s.sing or grouping the planting. See _Borders_ and _Flower Beds_. Particularly along the boundaries and about the foundations of buildings, the shrubbery and other plants may be ma.s.sed to excellent effect. In large places there should be more or less ma.s.s planting along the walks and drives. In the curves and retreats of these plantings one will find many pleasant corners; and here the children may have their play-houses and their pets. A little brook winding across a corner or along one side of a Lawn may make a pleasant picture if it is allowed to take on a half-wild character.

[Ill.u.s.tration: A layer]

LAYERS are parts (usually stems) of plants laid down on the earth while still attached to the parent, with the expectation that they will take root and can then be separated as independent plants. All vine-like plants can be propagated readily by means of Layers; so can most soft-wooded plants, as willows, maples, currants, etc. It is usual to put down the branches in the fall. In a year they should be ready to be severed from the parent. They may also be made in spring, before growth starts. See that the layered part rests in moist earth. Usually roots arise more freely if the shoot is cracked or notched at the buried point. The Layer may be held down by a forked stick ("pegged down"), or by a stone or clod. See that the shoot does not throw up suckers behind the layered part.

LEEK. This belongs to the onion family, and is used mostly as flavoring for soups. Well grown Leeks have a very agreeable and not very strong onion flavor. Leek is of the easiest culture, and is usually grown as a second crop, to follow beets, early peas, and other early stuff. The seed should be sown in a seed-bed in April or early May and the seedlings planted out in the garden in July, in rows 2 feet apart, the plants being 6 inches apart in the rows. The plants should be set deep if the neck or lower part of the leaves is to be used in a blanched condition. The soil may be drawn towards the plants in hoeing, to further the blanching. Being very hardy, the plants may be dug in late fall, and stored in the same manner as celery, in trenches or in a cool root-cellar. One ounce of seed to 100 feet of drill.

LETTUCE is probably the most extensively grown salad vegetable. It is now in demand, and is procurable, every month in the year. The winter and early spring crops are grown in forcing-houses and coldframes, but a supply from the garden may be had from April to November, by the use of a cheap frame in which to grow the first and last crops, relying on a succession of sowings for the intermediate supply. Seed for the first crop may be sown in a coldframe in March, growing the crop thick and having many plants which are small and tender; or, by thinning out to the distance of 3 inches and allowing the plants to make a larger growth, the plants pulled up may be set in the open ground for the next crop. Sowings should be made in the garden from April to October, at short intervals. A moist location should be selected for the July and August sowings. The early and late sowings should be of some loose-growing variety, as they are in edible condition sooner than the cabbage or heading varieties.

[Ill.u.s.tration: Plant of heading lettuce]

The cabbage varieties are far superior to the loose-growing kinds for salads. To be grown to perfection, they should have very rich soil, frequent cultivation and an occasional stimulant, such as liquid manure or nitrate of soda. The Cos Lettuce is an upright-growing type much esteemed in Europe, but less grown here. The leaves of the full grown plants are tied together, thus blanching the center, making it a desirable salad or garnishing variety. It thrives best in summer. One ounce of seed will grow 3,000 plants or sow 100 feet of drill. In the garden, plants may stand 6 inches apart in the rows, and the rows may be as close together as the system of tillage will allow.

LILY. Bulbous plants of many kinds. It has been said of this family of plants that it has no "poor relations," each of them being perfect in itself. Many of the choicest kinds are comparatively unknown, although easy to cultivate. In fact, all of the Lilies may be grown with comparative ease. A light, rich, well-drained soil, mellow to the depth of at least 1 foot, a handful of sand under each bulb if the soil is inclined to be stiff, and planting so that the crown of the bulb will be at least 4 inches below the surface, are the general requirements. One exception to the depth of planting is _Lilium auratum_, or Golden-Banded Lily. This should be planted deeper--at least 8 inches below the surface--as the new bulbs form over the old one and soon bring the bulbs to the surface if they are not planted deep.

While Lilies may have partial shade, they should never be planted near or under trees. The shade or protection of tall-growing, herbaceous plants is sufficient. In fact, the best results, both as to growth and effect, may be had by planting amongst low shrubbery or border plants.

Most kinds are the better for remaining undisturbed for a number of years; but if they are to be taken up and divided, or moved to other quarters, they should not be allowed to become dry. The small bulbs, or offsets, may be planted in the border, and if protected will grow to flowering size in two or three years. In taking up bulbs for division it is best to do so soon after the tops die after blooming. At least this should be done early in the fall, not later than October, giving the plants a chance to become established before freezing weather. A mulch of coa.r.s.e litter or evergreen boughs should be placed over the bulbs after the ground has become frozen, to be gradually removed as the spring advances.

[Ill.u.s.tration: Easter Lily]

As pot-plants some Lilies are very satisfactory, especially those that may be forced into bloom through the winter. The best kinds for this purpose are _L. Harrisii_ (Easter Lily), _L. longiflorum_, and _L.

candidum_. Others may be forced with success, but these are the ones most generally used. The winter culture of these for forcing is the same as for Hyacinths (in pots), which see. The article on _Bulbs_ gives directions for both outdoor and indoor growing which are directly applicable to Lilies.

LILY, CHINESE SACRED. See _Narcissus_.

LILY-OF-THE-VALLEY. A perfectly hardy little plant, bearing racemes of small white bell-shaped flowers in early spring. For ordinary cultivation, sods or mats of roots may be dug from any place in which the plant is colonized. Usually it thrives best in partial shade; and the leaves make an attractive mat on the north side of a building, or other shady place, in which gra.s.s will not grow. The plants will take care of themselves year after year.

For forcing indoors, imported roots or "pips" are used, as the plants are grown for this particular purpose in parts of Europe. These roots may be planted in pots, and treated as recommended for winter-flowering bulbs, under _Bulbs_. Florists force them in greater heat, however, often giving them a bottom heat of 80 or 90; but skill and experience are required in order to attain uniformly good results in this case.

LINE. A garden Line is one of the most convenient things connected with garden operations. It is always wanted when long rows of seed are to be sown, and it is also necessary in laying out walks or drives. A very simple, yet handy, holder for a line is shown on the margin. The pin is driven in the soil at the starting point, and the line is unwound as the operator walks towards the end of the row. A line should be 100 feet long for common garden operations.

LOBELIA. Some of these are well-known garden plants, being used very freely as edging for ribbon beds or basket plants. They require a loose, rich soil, and some stimulant when in full flower. The flowers continue through a long season. They propagate freely from seed. _Lobelia Erinus_, in blue, 6 inches high, is one of the most popular of all annual edging plants. In Europe various perennial Lobelias are popular, but they are seldom seen in American gardens.
