CURRANTS. The Currant, being one of the hardiest and most productive of fruits, is often neglected, the patch allowed to become foul with grass, never thinned or trimmed, the worms eating the leaves until, in the course of time, the plants weaken and die. Along the fence is no place to plant Currants, or, indeed, any other fruit; plant out in the open, at least 5 feet from anything that will interfere with cultivation. No fruit crop will respond more readily to good care than the Currant.

Clean cultivation and a liberal use of manure or fertilizers will certainly be followed by well paying crops. One- or two-year-old plants may be set 4 by 6 feet. Trim the bush by cutting off most of the suckers below the surface of the ground. If the season is dry, a mulch of straw or leaves will assist the plants to establish themselves.

The red and white Currants bear mostly on two-year-old or older wood. A succession of young shoots should be allowed to grow to take the place of the old bearing wood. Cut out the canes as they grow older. The partial shade afforded by a young orchard suits the Currant well, and if the ground is in good condition no bad results will follow to the orchard, provided the Currants are removed before the trees need the entire feeding space.

A Currant patch should continue in good bearing for 10 to 20 years, if properly handled. One very important point is to keep the old, weak canes cut out, and a succession of two to four new ones coming from the root each year. For home use, White Imperial and Moore's Ruby are excellent. Prince of Wales is a heavy bearer and excellent for cooking.

Wilder, Victoria, Cherry and White Grape are meritorious varieties.

To combat the Currant worm, spray thoroughly with Paris green to kill the first brood, just as soon as holes can be seen in the lower leaves--usually before the plants are in bloom. For the second brood, if it appear, spray with white hellebore. For borers, cut out and burn the affected canes.

CUTTINGS. Cuttings are parts of plants which are inserted in soil or water with the intention that they shall grow and make new plants. They are of various kinds. They may be classified, with reference to the age of the wood or tissue, into two classes; viz., those made from perfectly hard or dormant wood (taken from the winter twigs of trees and bushes), and those made from more or less immature or growing wood. They may be classified again in respect to the part of the plants from which they are taken, as root Cuttings, tuber Cuttings (as the ordinary "seed"

planted for potatoes), stem Cuttings and leaf Cuttings.

[Illustration: The planting of dormant wood Cuttings]

Dormant wood Cuttings are used for grapes, currants, gooseberries, willows, poplars and many other kinds of soft-wooded trees and shrubs.

Cuttings are ordinarily taken in fall or winter, but cut into the proper lengths and then buried in sand or moss where they do not freeze, in order that the lower end may heal over or callus. In the spring these Cuttings are set in the ground, preferably in a rather sandy and well drained place. Usually, hardwood Cuttings are made with two to four joints or buds, and when they are planted, only the upper bud projects above the ground. They may be planted erect, as the picture shows, or somewhat slanting. In order that the Cutting may reach down to moist earth, it is desirable that it should not be less than 6 inches long; and it is sometimes better if it is 8 to 12 inches. If the wood is short-jointed, there may be several buds on a Cutting of this length; and, in order to prevent too many shoots from arising from these buds, the lowermost buds are often cut out. Roots will start as readily if the lower buds are removed, since the buds grow into shoots and not into roots. Cuttings of currants, grapes, gooseberries, and the like may be set in rows which are far enough apart to admit of easy tillage either with horse or hand tools, and the Cuttings may be placed from 3 to 8 inches apart in the row. After the Cuttings have grown for one season, the plants are usually transplanted and given more room for the second year's growth, after which time they are ready to be set in permanent plantations. In some cases, the plants are set at the end of the first year; but two-year plants are stronger and usually preferable.

[Illustration: Root Cutting, which has given rise to a shoot]

Root Cuttings are used for blackberries, raspberries, and a few other things. They are ordinarily made of roots from the size of a lead pencil to one's little finger, and are cut in lengths from 3 to 5 inches long.

The Cuttings are stored the same as stem Cuttings and allowed to callus. In the spring they are planted in a horizontal or nearly horizontal position in moist, sandy soil, being entirely covered to a depth of 1 or 2 inches.

Softwood or greenwood Cuttings are always rooted under cover; that is, in a greenhouse, coldframe or dwelling house. They are usually made of wood which is mature enough to break when it is bent sharply. When the wood is so soft that it will bend and not break, it is too immature, in the majority of plants, for the making of good Cuttings. One to two joints is the proper length of a greenwood Cutting. If of two joints, the lower leaf should be cut off and the upper leaves cut in two, so that they do not present their entire surface to the air and thereby evaporate the plant juices too rapidly. If the Cutting is of only one joint, the lower end is usually cut just above a joint. In either case, the Cuttings are usually inserted in sand or well washed gravel, nearly or quite up to the leaves. Keep the bed uniformly moist throughout its depth, but avoid any soil which holds so much moisture that it becomes muddy and sour. These Cuttings should be shaded until they begin to emit their roots. Coleus, geraniums, fuchsias, and nearly all the common greenhouse and house plants, are propagated by these Cuttings or slips.

Leaf Cuttings are often used, for the fancy-leaved begonias, gloxinias, and a few other plants. The young plant usually arises most readily from the leaf-stalk or petiole. The leaf, therefore, is inserted into the ground much as a green Cutting is. Begonia leaves, however, will throw out young plants from the main veins when these veins or ribs are cut.

Therefore, well-grown and firm begonia leaves are sometimes laid flat on the sand and the main veins cut; then the leaf is weighted down with pebbles or pegs so that these cut surfaces come into intimate contact with the soil beneath. The begonia leaf may be treated in various other ways and still give good results. See _Begonia_.

In the growing of all greenwood Cuttings, it is well to remember that they should have a gentle bottom heat; the soil should be such that it will hold moisture and yet not remain wet; the air about the tops should not become close and stagnant, else the plants will damp off; and the tops should be shaded for a time.

[Illustration: Cuttings inserted in a double pot]

An excellent method of starting Cuttings in the living room is to make a double pot, as shown in the picture. Inside a 6-inch pot, set a 4-inch pot. Fill the bottom, _a_, with gravel or bits of brick, for drainage.

Plug the hole in the inside pot. Fill the spaces between, _c_, with earth, and in this set the Cuttings. Water may be poured into the inner pot, _b_, to supply the moisture.

CUTWORMS. Probably the remedy for Cutworms most often practiced in gardens, and which cannot fail to be effective when faithfully carried out, is hand-picking with lanterns at night or digging them out from around the base of the infested plants during the day. Bushels of Cutworms have been gathered in this way, and with profit. When from some cause success does not attend the use of the poisoned baits, discussed next, hand-picking is the only other method yet recommended which can be relied upon to check Cutworm depredations.

By far the best methods yet devised for killing Cutworms in any situation are the poisoned baits; hand-picking is usually unnecessary where they are thoroughly used. Poisoned bunches of clover or weeds have been thoroughly tested, even by the wagon-load, over large areas, and nearly all have reported them very effective; lamb's quarters (pigweed), pepper-grass and mullein are among the weeds especially attractive to Cutworms. On small areas the making of the baits is done by hand, but they have been prepared on a large scale by spraying the plants in the field, cutting them with a scythe or machine, and pitching them from wagons in small bunches wherever desired. Distributed a few feet apart between rows of garden plants at nightfall, they have attracted and killed enough Cutworms often to save a large proportion of the crop; if the bunches can be covered with a shingle, they will keep fresher much longer. The fresher the baits, and the more thoroughly the baiting is done, the more Cutworms one can destroy. However, it may sometimes happen that a sufficient quantity of such green succulent plants cannot be obtained early enough in the season in some localities. In this case, and we are not sure but in all cases, the poisoned bran mash can be used to the best advantage. It is easily made and applied at any time, is not expensive, and thus far the results show that it is a very attractive and effective bait. A tablespoonful can be quickly dropped around the base of each cabbage or tomato plant, small amounts can be easily scattered along the rows of onions, turnips, etc., or a little dropped on a hill of corn, cucumbers, etc. It was used on sweet potato hills in New Jersey last year, and "served as a complete protection, the Cutworms preferring the bran." It is well to apply it on the evening of the day the plants are set out.

The best time to apply these poisoned baits is two or three days before any plants have come up or been set out in the garden. If the ground has been properly prepared, the worms will have had but little to eat for several days and they will thus seize the first opportunity to appease their hunger upon the baits, and wholesale destruction will result. The baits should always be applied at this time wherever Cutworms are expected. But it is not too late usually to save most of a crop after the pests have made their presence known by cutting off some of the plants. Act promptly and use the baits freely.--_M. V. Slingerland._

[Illustration: Protection from cutworms]

Cutworms may be kept away from plants by making a collar of stiff paper or tin about the base, as in the picture; but this is not practicable on a large scale.

CYCLAMEN. A tender greenhouse tuberous plant, sometimes seen in the window-garden. Cyclamens may be grown from seed sown in April or September in soil containing a large proportion of sand and leaf-mold.

If sown in September, they should be wintered in a coolhouse. In May they should be potted into larger pots and placed in a shaded frame, and by July will have become large enough for their flowering pot, which should be either a 5- or 6-inch one. They should be brought into the house before danger of frost, and grown cool until through flowering. A temperature of 55 suits them while in flower. After flowering, they will need a rest for a short time, but should not become very dry, or the bulb will be injured. When they start into growth, they should have the old soil shaken off and be potted into smaller pots. At no time should more than half the tuber be under the soil.

Tubers large enough to flower the first year may be obtained from the seedsmen at moderate prices; and unless one has facilities for growing the seedlings for a year, purchase of the tubers will give the best satisfaction. The soil best suited to the Cyclamen is one containing two parts leaf-mold, 1 part each of sand and loam.

DAFFODILS are a kind of Narcissus. They are hardy, and require the treatment recommended for Crocus. They may be naturalized in the grass, but they usually do not persist long on account of our hot, dry summers.

Daffodils have been much improved of late. Plant in the fall, 4-6 in.

deep. Excellent old garden plants.

DAHLIA. The Dahlia is an old favorite which, on account of its formal flowers, has been in disfavor for a few years, although it has always held a place in the rural districts. Now, however, with the advent of the cactus and semi-cactus types (or loose-flowered forms), and the improvement of the singles, it again has taken a front rank among late summer flowers, coming in just in advance of the Chrysanthemum.

[Illustration: Dahlia]

The single varieties may be grown from seed, but the double sorts should be grown from cuttings of young stems or from division of the roots. If cuttings are to be made, it will be necessary to start the roots early either in a hotbed or house. When the growth has reached 4 or 5 inches, they may be cut from the plant and rooted in sand. Care should be taken to cut just below the joint, as a cutting made between two joints will not form tubers. The most rapid method of propagation of named varieties is to grow from cuttings in this way. In growing the plants from roots, the best plan is to place the whole root in gentle heat, covering slightly. When the young growth has started, the roots may be taken up, divided, and planted out 3 to 4 feet apart. This plan will ensure a plant from each piece of root, whereas if the roots are divided while dormant, there is danger of not having a bud at the end of each piece, in which case no growth will start.

[Illustration: Dahlia]

The Dahlia flourishes best in a deep, rich, moist soil, although very good results can be had on sandy soil, provided plant-food and moisture are furnished. Clay should be avoided. If the plants are to be grown without stakes, the center of each plant should be pinched out after making two or three joints. By doing this the lateral branches will start near the ground and be stiff enough to withstand the winds. In most home gardens the plants are allowed to reach their full height, and are tied to stakes if necessary. Dahlias are very susceptible to frost.

The tall kinds reach a height of 5-8 feet.

After the first frost, lift the roots, let them dry in the sun, shake off the dirt, trim off tops and broken parts, and store them in a cellar as you would potatoes. Cannas may be stored in the same place.

DAISY. The perennial English Daisy, or _Bellis perennis_, is a prime favorite as an edging plant. The cheerful little flowers show early in the spring, and with a little care bloom continuously through a long season. They should be given well enriched, moist soil, and be mulched through hot weather. The usual method of propagation is by division of the crowns, made in cool weather. They may also be grown from seed, but the chances are that many inferior flowers will be produced. Set the plants 3 or 4 inches apart. Height 3 to 5 inches. The colors are white, pink and red. Hardy if mulched in winter, but best results are obtained if plants are renewed frequently.

Many other plants are called Daisy, particularly the wild Asters, the Ox-eye Daisy or Whiteweed, and the Paris Daisy (_Chrysanthemum frutescens_).

DAMPING OFF is the rotting off of cuttings or young plants near the surface of the soil. It is the work of fungi; but these fungi are injurious because they find conditions congenial to their rapid growth.

Prevention is worth more than cure. See that the soil is wet clear through, not wet on top and dry beneath. Keep it as dry as possible on the surface. Avoid soggy soils. On peaty soils, sprinkle sand or coal ashes to keep the top dry. Give the plants free circulation of air. Give them abundance of room. If Damping Off threatens, transplant.

DANDELION. This common weed would hardly be recognized if seen under cultivation in the vegetable garden. The plants attain a large size and the leaves are much more tender. The seed may be selected from the best field-growing plants, but it is better to buy the French seed of the seedsmen.

Sow in spring in well manured soil, either in drills or in hills 1 foot apart. A cutting of leaves may be had in September or October, and some of the stools may stand until spring. The delicacy of the leaves may be improved by blanching them, either by the use of boards or earth. One trade packet of seed will supply a large number of plants. The whole plant is destroyed when the crop of leaves is taken.

DATURA. BRUGMANSIA. Large-growing annuals with large, trumpet-shaped flowers. The coloring of some of the flowers is very attractive, but the odor of the plant is unpleasant. Plants should be set 4 feet apart. They grow 3-4 feet high, bear large leaves, and therefore make good low screens. Frost kills them. Sow seed where plants are to grow; or, better, start them in the house three or four weeks before the weather is fit for planting outside. Some of the Daturas are weeds. The great spiny seed pods are interesting.

DELPHINIUM. See _Larkspur_.

DEWBERRY. The Dewberry may be called an early trailing blackberry. The culture of this, as of the blackberry, is very simple; but, unlike the latter, some support should be given to the canes, as they are very slender and rank growers. A wire trellis or large-meshed fence-wire answers admirably; or (and this is the better general method) they may be tied to stakes. The fruits are large and showy, which, combined with their earliness, makes them desirable; but they are usually deficient in flavor. The Lucretia is the leading variety in cultivation.

[Illustration: Lucretia Dewberry]

Lay the canes on the ground in winter. In the spring tie all the canes from each plant to a stake. After fruiting, cut the old canes and burn them (as for blackberries). In the meantime, the young canes (for next year's fruiting) are growing. These may be tied up as they grow, to be out of the way of the cultivator. Dewberries are one to two weeks earlier than blackberries.
