The native Ferns transplant easily to the garden, and they make an attractive addition to the side of a house, or as an admixture in a hardy border. The Ostrich and Cinnamon Ferns are the best subjects. Give all outdoor Ferns a place which is protected from winds, otherwise they will shrivel and perhaps die. Screen them from the hot sun, or give them the shady side of the building. See that the soil is uniformly moist, and that it does not get too hot. Mulch with leaf-mold in the fall.

FERTILIZERS. Soil is productive when it has good physical texture, plant-food, and a sufficient supply of moisture. Even though it has an abundance of plant-food, if its texture is not good, it will not raise a good crop. Soil has good texture when it is open, mellow, friable, rather than loose and leachy, or hard and cloddy. Commercial Fertilizers add plant-food, but usually they have only a small influence in correcting faulty texture. Therefore, before concentrated Fertilizers are applied to land, it should be gotten into good physical condition by judicious tillage and by the incorporation of vegetable mold or humus.

The leading source of humus in most gardens is stable manure. See _Manure_.

The plant-food in commercial Fertilizers is largely in a soluble or quickly available condition. Therefore, a little Fertilizer applied late in the fall or early in the spring will tend to start the plants off quickly in the spring and to cause them to become established before the trying weather of summer. For garden purposes, it is usually advisable to buy one of the so-called complete Fertilizers; that is, one which contains nitrogen, potash and phosphoric acid. If a luxuriant growth of stalk and foliage is wanted rather than flowers or fruit, an application of nitrogen alone is usually advisable. The most readily available nitrogen in commercial form is that which is afforded by nitrate of soda and sulfate of ammonia. In garden practice this may be applied at the rate of 300 to 400 pounds an acre, although this quantity is more than is profitable to use in most general field or agricultural conditions.

If it is desired to have stout, stocky plants, with early and profuse bloom, it is ordinarily advisable to use somewhat sparingly of nitrogen and to use a little more heavily of potash and phosphoric acid. This is especially true of the leguminous plants, which have the power of appropriating atmospheric nitrogen, and among such plants are sweet peas. Heavy fertilizing of sweet pea land with strong stable manure tends to make the vines grow too tall and to bear comparatively few flowers. For dressing of lawns, a Fertilizer which is comparatively rich in nitrogen is usually to be advised.

An important value of commercial Fertilizers is to use them to start off the plants quickly in the spring. The food is available and acts at once. When used for this purpose, the Fertilizer may be applied in the hill; but when it is desired for the enriching of the land and for the support of the crop throughout the season, it should be applied to the entire surface. Always avoid putting the Fertilizer on the crown of the plant, or directly in contact with it. It is usually better to work the Fertilizer in lightly. For most garden operations, it is better to apply in spring.

FEVERFEW. See _Pyrethrum_.

FIG. The Fig is little grown in the East except as a curiosity, but on the Pacific coast it has gained more or less prominence as an orchard fruit. The trees are usually planted at distances of about 18 to 25 feet apart. Figs will stand considerable frost, and seedling or inferior varieties grow out of doors without protection as far north as Virginia.

Many of the varieties fruit on young sprouts, and, inasmuch as the roots will stand considerable cold, these varieties will often give a few Figs in the northern states. Figs have been fruited in the open ground in Michigan. In all frosty countries, however, the Fig should be laid down during the winter time. The following notes from Professor Massey, of North Carolina, indicate how this may be done:

"The light hoar-frosts that have occurred here affected vegetation only on low grounds, and today (November 5) our gardens on high ground show no signs of frost. Lima beans and tomato vines are as green as in summer time, and this morning we gathered ripe Figs from our trees in the garden--the latest I have ever known Figs to ripen. As the early crop of Figs ripens in July (if it escapes the winter frosts, for the fruit is now set on the trees), and the late crop begins in August and continues to ripen in succession till frost, it is easy to see what a desirable fruit the Fig is. In this section it is easy to have a great abundance of Figs, and it is possible almost anywhere in the United States to have both early and late crops in abundance by taking a little trouble to protect the trees in winter. Years ago the writer grew Figs in abundance in a very cold locality in northern Maryland, and never failed to get a good crop. Where the winter temperature seldom drops lower than 18 or 20 above zero, Figs will need no special protection if sheltered from cold winds. In colder climates they should be branched from the ground, and, after the leaves have fallen, be bent to the ground in four bundles and covered with earth, making a sharp mound over the center and sloping off like a four-pointed star or cross, as shown in the cuts, taken from Bulletin 74 of North Carolina Experiment Station."

FLOWER BEDS. Two classes of subjects are to be considered in the discussion of Flower Beds: those concerned with the location of the bed; those concerned with the actual making of the bed itself. Most persons do not consider the former subject. If one wants a flower garden in which there is to be a collection of plants grown for the plants' sake, the garden should be placed at the rear or one side, and may be laid out in regular fashion like a vegetable garden. If the flowers are to be a part of the home picture,--that is, a part of the place itself,--then they may be freely distributed amongst the border planting, or as edgings along groups of shrubbery. It is rarely, if ever, allowable to place formal beds in the lawn in home grounds. The place for carpet-bedding is usually in parks or other public areas, in sections which are set aside and devoted to that particular purpose, the same as another section may be devoted to a zoological garden, play-ground or to other specific use. Flowers which are grown in the middle of the lawn have little relation to other planting, and they have no background to show them off to good advantage. It is also difficult to grow them in small beds in the grass, since they are exposed to sun and wind, and the grass roots absorb the food and moisture. In the formal bed, every effort must be made to keep it prim, otherwise it becomes displeasing; whereas, if the flowers are planted more or less promiscuously in large, irregular borders, or along the edge of shrubbery, the failure of one or even of a dozen plants is not a serious matter. The growing of plants in formal designs requires so much care and attention that a large part of the fun of plant-growing is lost. Such plant-growing should ordinarily be left to those who make a business of it.

In making a Flower Bed, see that the ground is well drained; that the subsoil is deep; that the land is in a mellow and friable condition, and that it is rich. Each fall it may have a mulch of rotted manure or of leaf-mold, which may be spaded under deeply in the spring; or the land may be spaded and left rough in the fall, which is a good practice when the soil has much clay. Make the Flower Beds as broad as possible, so that the roots of the grass running in from either side will not meet beneath the flowers and rob them of food and moisture. It is well to add a little commercial fertilizer each fall or spring.

FLOWERING MAPLE. See _Abutilon_.

FORGET-ME-NOT. This old favorite grows so easily, looks so cheerful, and with a little care will bloom so long, that it should have a place in every collection of flowering plants. It is perennial, but the best results may be had by dividing the roots as often as every other year; or seedlings may be taken up from around the old plants. They require a moist soil, with shade a part of the day. They will thrive exceedingly if grown in a frame like pansies. Easily grown from seeds, usually blooming the first fall. Excellent for low edgings. Height 6 inches.

FOUR-O'CLOCK. MIRABILIS. Tender annual, a plant of old-fashioned gardens, and always interesting. Grows 2 to 3 feet high. Drop seeds where the plants are to stand, thinning them to 12 to 18 inches apart.

The colors are white and pink. There are variegated-leaved forms; also dwarfs. Excellent for the back row in a bed of annuals.

[Illustration: Foxglove]

FOXGLOVE, or DIGITALIS. Foxgloves make most effective border plants, either as a background or planted among other things. The tall flower-spikes are covered during the blooming period with funnel-shaped drooping flowers in various colors and with fine markings. Some of the newer varieties have flowers that rival the Gloxinias in shadings and markings. The plants are perfectly hardy, growing in one situation for a number of years; but, as with many other perennials, they are all the better for being divided at intervals. They may be grown readily from seed. Sow in boxes under glass or in the border where wanted. They bloom the second year. A rich, deep soil and partial shade suit their requirements. Period of bloom, July and August. Height 2 to 4 feet.

FRAME. See _Hotbed_ and _Coldframe_.

FREESIA. One of the best and most easily handled winter-flowering bulbs.

The white or yellowish bell-shaped flowers are produced on slender stalks just above the foliage, to the number of six to eight in a cluster. They are very fragrant, and last for a considerable time when picked. The bulbs are small, and look as though they could not produce a growth of foliage and flowers, but even the smallest mature bulb will prove satisfactory. Several bulbs should be planted together in a pot, box or pan, in October, if wanted for the holidays, or later if wanted at Easter. The plants bloom from ten to twelve weeks from planting, under ordinary care. No special treatment is required; keep the plants cool and moist through the growing season. The soil should contain a little sand mixed with fibrous loam, and the pot should be well drained.

After flowering, gradually withhold water and the tops will die down, after which the roots may be shaken out and rested until time to plant in fall. Care should be taken to keep them perfectly dry. The bulbs increase rapidly from offsets. Plants may also be grown from seed, which should be sown as soon as ripe, giving blooming plants the second or third year. Height 12 or 15 inches. Easy to bloom in the window. The white form (_Freesia refracta alba_) is the best. See _Bulbs_.

FRITILLARIA, or FRITILLARY. Bulbous plants, the commoner species hardy.

Only the Crown Imperial is well known in this country. This is an old-fashioned plant, which takes care of itself when once planted. The other hardy Fritillarias are treated like tulips.

FROST. The light frosts of late spring and of early fall may be prevented by any means which will keep the air in motion, or which will fill the air with moisture or cloud-like vapor, so that there is less radiation from the ground. When frost is expected, it is well to water the plants and the ground thoroughly. This will ordinarily protect them from two or three degrees of still frost. The water should be applied just at nightfall. On larger areas, it is often practicable to make a smudge. In order to be effective, the smudge must be rather dense and lie over the whole area, and it should be kept up until the danger from frost is past. Material which burns very slowly and with much smoke is preferable. Moist manure or straw or other litter is useful. Materials which are dry enough to blaze are of little use. Ordinarily, frost comes towards morning. It is well to have the piles of rubbish ready at nightfall and have them lighted toward the latter part of the night, when the frost is expected. The smudge should be kept up until sunrise.

It is well to have these piles of smudge material on all sides of the area; or if the area is on a slope, it may be sufficient to have them on the upper side, for there is usually a movement of air down the hillside and the area will thereby be covered with the smudge. For a thorough protection, it is best to have many small piles rather than a few large ones. If the piles are placed every ten feet around the areas, better results are to be expected. There are especially prepared tar-like materials for use in smudging plantations, but they are little used in this country, although some of them are excellent.

[Illustration: Fuchsia]

FUCHSIA. Well-known window or greenhouse shrub. It is readily grown from cuttings. Soft, green wood should be used for cuttings, and it will root in about three weeks, when the cuttings should be potted. Take care not to have them pot-bound while in growth, but do not over-pot when bloom is wanted. Given warmth and good soil, they will make fine plants in three months or less. In well protected, partially shady places they may be planted out, growing into miniature bushes by fall. Plants may be kept on from year to year; and if the branches are well cut back after blooming, abundant new bloom will come. But it is usually best to make new plants each year from cuttings, since young plants usually bloom most profusely and demand less care. Fuchsias are amongst the best of window subjects.

FUMIGATION is mentioned under _Insects_.

FUNGI. Flowerless, leafless plants, living mostly on food (either living or dead) which has been prepared by other plants or by animals, Molds, mushrooms and puff-balls are familiar examples. Some of the parasitic kinds cause great damage to the plants or animals on which they live.

Examples of these injurious parasitic kinds are apple-scab fungus, potato mildew, grape mildew, corn smut fungus, and the like. Most of these are combated by spraying with materials containing copper or sulfur.

FUNKIA, or DAY LILY. Hardy perennial herbs, growing in dense clumps and bearing attractive foliage. They are of the easiest culture. _F.

subcordata_, the white-flowered species, is commonest. Of blue-flowered forms there are several, of which _F. ovata_ (or _F. caerulca_) is perhaps the best. Funkias are excellent for borders, or as a formal edging to long walks or drives. There are variegated forms. Funkias grow 12 to 24 inches high, and the flower clusters stand still higher.

Propagated by dividing the roots. Day Lily is a name applied also to species of Hemerocallis, which are yellow-flowered lilies.

GAILLARDIAS are plants that should have a place in every garden, either as border plants or for cutting. The flowers are very showy and lasting in bouquets, as well as on the plants. The double form has perfect balls of color. Gaillardias are both annual and perennial. The perennials usually have flowers much larger than the annuals; and they bloom the first year if seed is started early. These are also propagated by seed or cuttings. If from seed, it should be sown under glass in February or March, setting out the young plants where wanted when danger of frost is over. The cuttings may be made of the new growth in the fall and wintered over in the house. Set 2 feet apart. Height 2 feet, blooming from July until hard frosts. The perennials are usually orange.

[Illustration: Gaillardia picta]

The annual kind (_Gaillardia picta_ of florists) is probably the best kind for the home garden. It is of the easiest culture. Hardy. Two feet.

Sow seeds where plants are to bloom. The colors of the flowers are in rich shades of yellow and red.

GALANTHUS. See _Snowdrop_.

GARLIC. An onion-like plant, the bulbs of which are used for flavoring.

Little known in this country except amongst those of foreign birth. It is multiplied the same as multiplier onions--the bulb is broken apart and each bulbule or "clove" makes a new compound bulb in a few weeks.

Hardy; plant in early spring, or in the South in the fall. Plant 2 to 3 inches apart in the row.

GAS PLANT is _Dictamnus_.

GERANIUM. What are generally known as Geraniums are, strictly speaking, Pelargoniums, which see. The true Geraniums are mostly hardy plants, and therefore should not be confounded with the tender Pelargoniums.

Geraniums are worthy a place in a border. They are hardy perennials, and may be transplanted early in the spring, setting them 2 feet apart.
