BROCCOLI. This is almost identical with the Cauliflower, except that it usually requires a longer season and matures in the fall. It is grown more generally in Europe than in this country. The special merit of Broccoli is its adaptability for late summer planting and its rapid growth in the late fall. It is said that a large proportion of Broccoli is used in the manufacture of pickles. The culture is the same as for Cauliflower,--deep, moist soil well enriched, cool weather, and the destruction of the cabbage worm.
The young plants may be grown in a coldframe or in a well protected border, sowing the seed about the 15th of May, transplanting into rows in July. In sections in which early fall frosts are not to be feared, the plants may be set two weeks later, say August 1, as all vegetables of the cabbage family make the best growth through the cool months of September and October. The plants should be set 18 in. apart in the rows, the rows being from 2 ft. to 3 ft. apart.
BROWALLIA ELATA is a very fine tender annual, giving a border or mixed bed a dash of amethyst blue not often found in flowers. It is a strong-growing plant with a profusion of bloom, and no doubt one of the choicest plants of its color in cultivation. There are other species with white flowers that serve as contrast, and may be grown with this.
All of the kinds may be taken up and potted in the fall, cutting the plant well back, and a profusion of bloom may be obtained through the winter months if attention is given to pinching off the seed pods. In the garden, let the plants stand 12 in. apart. The plants grow 1-2 ft.
high.
BRUSSELS SPROUTS. This is a vegetable that should be more generally known, as it is one of the choicest of the cabbage family, and may be had at its best after the season for cauliflower has pa.s.sed. It is the better for being touched by the fall frosts. The parts used are the b.u.t.tons or sprouts (miniature cabbage heads) that grow thickly along the stem. These should be cut off rather than broken. The very small hard "sprouts" or b.u.t.tons are the best. The culture is essentially the same as for late cabbage or broccoli. One ounce will sow 100 ft. of drill, or make upward of 2,000 plants. Set plants in field 2-3 ft. apart. They require the entire season in which to grow.
BUDDING. See _Grafting_.
BULBS. The outdoor culture of bulbs is extremely simple. They care for themselves throughout a greater part of the year, many of them flowering when no other plants are able to grow and bloom out of doors.
While all the so-called Holland bulbs will thrive in any kind of soil, they will all do better by being planted in a deep, sandy soil well enriched with well rotted manure. But do not let the manure come into direct contact with the bulb. Even heavy clay soil may be fitted for the growing of bulbs by the addition of sharp sand, either worked into the soil or placed directly under the bulb when planted. To make a bulb bed, choose, if possible, a sandy soil and throw out the top soil to the depth of 6 in. Put into the bottom of the bed about 2 in. of well rotted manure and spade it into the soil. Throw back half of the top soil, level it off nicely, set the bulbs firmly on this bed and then cover them with the balance of the soil; in this way one will have the bulbs from 3 to 4 in. below the surface. In the fall months the top of the ground is cooler than at the depth of 5 or 6 in. and the top of the bulb will not want to grow, while the bottom, which is always in a hurry, will send out roots, to push out the leaves and flowers the next spring.
When the weather is cold enough to freeze a hard crust on the soil, the bed should have its winter overcoat. This may be straw, hay, cornstalks or leaves spread over the bed to the depth of 6 in. if the material is coa.r.s.e; but if leaves are used, 3 in. will be enough, because the leaves lay close together and may smother out the frost that is in the ground and let the bulbs start. What we want is to keep them asleep until spring, because if they start too early the hard freezes of March and early April will spoil their beauty if the leaves or flowers are near or above the surface. Early in April, in New York, the covering may be removed gradually, and should all be off the beds before the leaves show above the ground.
If there is no sandy place for the beds, make them as directed, leaving the stones in the bottom of the bed for drainage. Then, when ready to set the bulb, place a large handful of sand where the bulb is to go and set the bulb on it. This will keep the water from standing around the bulb. Very fine results may be had on heavy soil by this method.
As to kinds of bulbs, select hyacinths, tulips or narcissus or daffodils, with snowdrops or crocuses of various colors around the edge.
For the culture of these and other bulbs, see the various articles throughout the book.
_The growing of flowering bulbs through the winter_ adds to the list of house plants a charming variety. The labor, time and skill required is much less than that of growing many of the larger plants more commonly used for winter decorations. The larger number of winter bulbs may be left out of doors until within four to six weeks of the time when they are wanted in flower. Hyacinths, narcissus, tulips, and crocus can be made to flower in the winter without difficulty. Secure the bulbs so as to be able to pot them by the middle or last of October, or if earlier all the better. The soil should be rich, sandy loam, if possible; if not, the best one can get, to which add about one-fourth the bulk of sand and mix thoroughly. If ordinary flower pots are to be used, put in the bottom a few pieces of broken pots, charcoal or small stones for drainage, then fill the pot with dirt so that when the bulbs are set on the dirt the top of the bulb is even with the rim of the pot. Fill around it with soil, leaving just the tip of the bulb showing above the dirt. If the soil is heavy, a good plan is to sprinkle a small handful of sand under the bulb to carry off the water, the same as is done in the beds outdoors. If one does not have pots he may use boxes. Starch boxes are a good size to use, as they are not heavy to handle; and excellent flowers are sometimes obtained from bulbs planted in old tomato cans. If boxes or cans are used, care must be taken to have holes in the bottoms to let the water run out. A large size hyacinth bulb will do well in a 5-inch pot. The same size pot will do for three or four narcissuses or eight to twelve crocuses.
After the bulbs are planted in the pots or other receptacles, they should be placed in a cool place, either in a cold pit or cellar, or on the shady side of a building, or, better yet, plunged or buried up to the rim of the pot in a shady border. This is done to force the roots to grow while the top stands still; as only the bulbs with good roots will give good flowers. When the weather gets so cold that a crust is frozen on the soil, the pots should be covered with a little straw, and as the weather gets colder more straw must be used. In from six to eight weeks after planting the bulbs, they should have made roots enough to grow the plant, and they may be taken up and placed in a cool room for a week or so, after which, if they have started into growth, they may be taken into a warmer room where they can have plenty of light. They will grow very rapidly now and will want lots of water, and after the flowers begin to show, the pots may stand in a saucer of water all the time.
When just coming into bloom the plants may have full sunlight part of the time to help bring out the color of the flowers.
BUSHES. See _Shrubs_.
CABBAGE. For an early crop, the plants must be started either in February or early March, or the previous September and wintered over in coldframes. This latter method was once a common practice by gardeners near large cities, but the building of greenhouses to replace the many hotbeds of the market-gardener has changed the practice in many localities, and now most of the early Cabbages in the north are grown from seed sown in January, February or March. The plants are hardened off in March and early April and planted out as early as possible. The private grower, or one with a small garden, may often procure his early plants from the market-gardener much cheaper than he can grow them, as usually only a limited number of early Cabbage plants are wanted; but for the midseason and main crop, the seed may be sown in May or June, setting the plants in July.
[Ill.u.s.tration: Early Cabbage]
For early planting, the number of varieties is limited to three or four.
For an intermediate crop the list is more extended, and the late varieties are very numerous. The early list is headed by the Jersey Wakefield, a variety which heads very quickly, and, although not one of the solid kinds, is generally grown. The Early York and Winnigstadt are good varieties to follow it. The latter especially is solid and of very good quality. For the midseason, the Succession and All Season are of the best, and for the winter supply the Drumhead, Danish Ball and Flat Dutch types are the leaders. One of the best of the Cabbages for table use is seldom seen in the garden--the Savoy Cabbage. It is a type with netted leaves, making a large, low-growing head, the center of which is very solid and of excellent flavor, especially late in the fall, when the heads have had a slight touch of frost. Savoy should be grown in every private garden.
The seed-bed should be made mellow and rich. A good border will do. The seed is sown preferably in rows, thus allowing thinning of the plants and the pulling of any weeds that germinate. The young plants will well repay attention to watering and thinning. The rows should be 3 or 4 in.
apart. When the plants are large enough to transplant, they may be planted where early vegetables have been grown. Set the plants from 18 to 24 in. apart in the row, the rows being 3 ft. apart for the medium-growing kinds. One ounce of seed will furnish about two thousand plants. All Cabbages require deep and rich soil, and one that holds moisture well.
The best remedy for the Cabbage worm is to kill the first brood on the very young plants with Paris green. After the plants begin to head, pyrethrum or salt water may be used. On a small area, hand-picking may be recommended.
The maggot is the most serious Cabbage pest. After studying the seventy odd remedies proposed, Slingerland concludes that 6 are efficient and practicable: growing the young plants in closely covered frames; tarred paper cards placed snugly about the base of the plants to keep the fly away; rubbing the eggs from the base of the plant; hand-picking of the maggots; treating the plants with emulsion of carbolic acid; treating them with carbon bisulfide. The insecticidal materials are injected or poured into the soil about the base of the plant.
Respecting these two insecticides, Slingerland remarks: "Always use the crude carbolic acid, as it is much cheaper than the purified and is nearly, if not quite, as effective. It will probably be safer if used as an emulsion than if simply diluted with water. We would advise that it be made by the follow formula: 1 pound of hard soap or 1 quart of soft soap dissolved in 1 gallon of boiling water, into which 1 pint of crude carbolic acid is then poured and the whole ma.s.s agitated into an emulsion, which will remain in this condition for a long time. In treating the plants, take one part of this standard emulsion and dilute it with 30 equal parts of water; it probably can be used stronger without injury to the plants. If the emulsion is cold and semi-solid, use several parts of warm water at first. Begin the treatment early, a day or two after the plants are up, or in the case of Cabbages and Cauliflowers the next day after they are set in the field, and repeat it once each week or 10 days until about May 20 in our state. While we have little faith in the preventive effects of the early treatments, we do believe that the emulsion will then kill many of the eggs and recently hatched maggots. If it could be applied with some force through a syringe or force pump, it might not be necessary to go to the trouble of first removing some of the earth from about the plants. It must be remembered that its success will depend on the eggs or maggots being hit with it. None of the Cabbages in our experiment were injured in the least by an application containing nearly twice as much of the acid, and there is but little danger of its injuring the tenderest foliage of radishes, turnips or onions; if any injury manifests itself on these crops, dilute the emulsion with 40 or 50 or more parts of water, instead of 30. A knapsack or wheelbarrow sprayer would prove a very useful instrument in applying the emulsion on a large scale."
The carbon bisulfide is best injected into the soil by means of a long-nosed syringe. Slingerland (Cornell Bulletin 78) ill.u.s.trates a specially made syringe or injector for this purpose: "Thus Cabbage plants can be treated once, and once is usually sufficient, at the rate of about 10 plants for 1 cent for the liquid, using about 1 teaspoonful to each plant. As the injector will last for years, and several neighbors might join in the purchase and use of one instrument, its cost would practically not influence this estimate of the cost of killing the maggots. We believe it is the cheapest, most effective, and most practicable method yet devised for fighting this pest on crops of Cabbages and cauliflowers; on crops of radishes, turnips, or onions it will probably be too expensive except where choice or new varieties are attacked. The carbolic acid emulsion will prove the most practicable on these last crops."
The club-root, which causes the roots to become greatly thickened and distorted, is difficult to manage if Cabbages or allied plants are grown continuously on land in which diseased plants have been raised. Changing the location of the Cabbage or Cauliflower patch is the best procedure.
If very different crops, as corn, potatoes, peas, tomatoes, etc., are grown on the land, the disease will be starved out in two or three years.
CACALIA. Ta.s.sEL FLOWER. LADIES" PAINT BRUSH. A quaint old annual, in two colors, scarlet and orange. It is easily grown, and makes a fine second-row plant for a border, contrasting well with Browallia or Ageratum. Sow where the plants are to stand. Let plants stand 10-12 inches apart. Grow 1-2 ft. high.
CACTUS. This cla.s.s of plants is often seen in small collections of house plants, to which they add interest, being altogether different from other plants. All Cacti are easy to grow, requiring but little care and enduring the heat and dryness of a living room much better than most other plants. Their requirements are ample drainage and a sandy soil.
Cactus growers usually make a soil by mixing pulverized plaster or lime refuse with garden loam, using about two-thirds of the loam. The very fine parts, or dust, of the plaster, are blown out, else the soil is likely to cement. They may be rested at any season by simply setting them away in a dry place for two or three months, and bringing them into heat and light when they are wanted. As new growth advances they should have water occasionally, and when in bloom they should be watered freely. Withhold water gradually after blooming until they are to be rested.
Some of the most common species in cultivation are the Phyllocactus species, often called the Night-blooming Cereus. These are not the true Night-blooming Cereuses, which have angular or cylindrical stems, covered with bristles, while this has flat, leaf-like branches; the flowers of these, however, are very much like the Cereus, opening at evening and closing before morning, and as the Phyllocacti may be grown with greater ease, blooming on smaller and younger plants, they are to be recommended. See _Cereus_.
The Epiphyllum, or Lobster Cactus, is one of the best of the family, easy of culture. It bears bright-colored blossoms at the end of each joint. When in flower, which will be through some of the winter months, this requires a richer soil than the other Cacti. Opuntias, or p.r.i.c.kly pears, are often grown as border plants through the summer. In fact, all the family may be planted out, and if a number of varieties are set in a bed together they make a striking addition to the garden. Be very careful not to bruise the plants. It is better to plunge them in the pots than to turn them out of the pots.
[Ill.u.s.tration: Caladium or Colocasia]
CALADIUM. Tuberous-rooted, tender perennial plants which are used for conservatory decorations, and also for subtropical and bold effects in the lawn. The plants which are commonly known under this name are really Colocasias. The plants should be rested during the winter, being kept in a warm cellar or under a greenhouse bench, where they are not liable to frost or dampness. The roots are usually kept covered with earth during the winter, but they are kept dry. Early in the spring the roots are put into boxes or pots and are started into growth, so that by the time settled weather comes they will be 1 or 2 feet high and ready to set directly into soil. When set out of doors, they should be given a place which is protected from strong winds, and one which does not receive the full glare of direct sunlight. The soil should be rich and deep, and the plants should have an abundance of water. Caladiums are most excellent plants for striking effects, especially against a house, high shrubbery or other background. If they are planted by themselves, they should be in clumps rather than scattered as single specimens, as the effect is better. See that they get a good start before they are planted in the open ground.
CALCEOLARIA. Small greenhouse herbs which are sometimes used in the window-garden. They are not very satisfactory plants for window treatment, however, since they suffer from dry atmosphere and from sudden changes of temperature. In the window-garden they should be protected from strong, direct sunlight. They are grown from seeds. If the seeds are sown in early summer and the young plants are transplanted as they need, flowering specimens may be had for the late fall and early winter. In the growing of the young plants, always avoid exposing them to direct sunlight; but they should be given a place which has an abundance of screened or tempered light. A new crop of plants should be raised each year. There is a race of shrubby Calceolarias, but it is little known in this country. One or two species are annuals which are adaptable to cultivation in the open garden, and their little, ladyslipper-like flowers are attractive. However, they are of secondary importance as annual garden flowers.
CALENDULA. These are the well known POT MARIGOLDS, and add a bright spot to any garden. Annual. Especially are they fine in the cool days of the fall, when many of the annual flowers have gone to seed. The places of short-lived plants may be filled by sowing seed of Calendulas in May, scattering them through the border and allowing the plants to grow where they come up. Easy of growth and hardy. 1-2 ft. high. Should stand 8-12 in. apart. Colors, yellow and orange.
[Ill.u.s.tration: California Poppy]
CALIFORNIA POPPY (_Eschscholtzia Californica_). Low perennial, poppy-like plant, grown as a hardy annual. It is certainly one of the best low-growing annuals, blooming through a long season and being at its best through the cool days of fall, after touched by frost. Most of the varieties have flowers of fine shades of orange or yellow, making a bright spot in the border at all times. They are like the pot marigolds, in that once planted they seed themselves. They are never out of place, and should be left to bloom wherever they may be. Flowers open only in sunshine. As cut-flowers they are excellent, a large bowl of them glowing like a golden ball, especially if they are emphasized by a few blue larkspurs or bachelor"s b.u.t.tons.
Propagated by seed, which would best be sown as soon as ripe, thus giving the plant an early start, and having bloom through the season.
They make attractive mats of foliage. 12-18 in. high. Let the plants stand 10-20 in. apart.
CALLA (properly _Richardia_). EGYPTIAN LILY. All things considered, this is one of the most satisfactory of winter house plants, lending itself to various conditions. The requirements of the Calla are rich soil and an abundance of water, with the roots confined in as small a s.p.a.ce as possible. If a too large pot is used the growth of foliage will be very rank, at the expense of the flowers, but by using a smaller sized pot and applying liquid manure the flowers will be produced freely. A 6-inch pot will be large enough for all but an exceptionally large bulb. If desired, a number of bulbs may be grown together in a larger pot. The soil should be very rich but fibrous--at least one-third well rotted manure will be none too much, mixed with equal parts of fibrous loam and sharp sand. The tubers should be planted firmly and the pots set in a cool place to make roots. After the roots have partially filled the pot, the plant may be brought into heat and given a sunny position and an abundance of water. An occasional sponging or washing of the leaves will free them from dust. No other treatment will be required until the flowers appear, when liquid manure may be given. The plant will thrive all the better at this time if the pot is placed in a saucer of water.
In fact, the Calla will grow finely in an aquarium. The Calla may be grown through the entire year, but it will prove more satisfactory, both in leaf and flower, if rested through part of the summer. This may be done by laying the pots on their sides in a dry, shady place under shrubbery, or if in the open slightly covered with straw or other litter to keep the roots from becoming extremely dry. In September or October they may be shaken out, cleaning off all the old soil, and repotted, as already mentioned. The offsets may be taken off and set in small pots and given a year"s growth, resting them the second year and having them in flower that winter.
The spotted Calla has variegated foliage and is a fine plant for mixed collections. This blooms in the spring, which will lengthen the season of Calla bloom. The treatment of this is similar to that of the common Calla.
CALLIOPSIS is a garden name for _Coreopsis_.
CALLIRRHOe. _C. pedata_ is a hardy annual which has large, graceful blossoms of violet or red. Is it a very free-blooming plant. Should be started in a frame and planted out where wanted. 2-3 ft. high and grows bushy. Plants should stand 1-2 ft. apart.
CAMELLIA. Years ago Camellias were very popular, but they have been crowded out by the informal flowers of recent times. Their time will come again. They are half-hardy woody plants, blooming in late winter and spring. During the blooming season keep them cool--say not over 50 at night and a little higher by day. When blooming is done they begin to grow, then give them more heat and plenty of water. See that they are well ripened by winter. Always screen them from direct sunlight. Do not try to force them in early winter, after the growth has ceased. Their summer quarters may be in a protected place in the open air. Propagated by cuttings in winter, which should give blooming plants in two years.
