The Culture Of Vegetables And Flowers From Seeds And Roots 16th
Chapter 35
A word is necessary as to soil. The Begonia is a gross feeder, and to develop its fine qualities there must be a liberal employment of manure. As a matter of fact, it is scarcely possible to make the soil too rich for this flower.
CHIONODOXA
Glory of the Snow
The varied blue tints of the Chionodoxa, its more open blossoms, and larger size, distinguish this flower from its older and justly prized rival, the Scilla. Indeed, the Chionodoxa is exquisitely beautiful, and of great value for pot culture, beds, or borders. Five bulbs may be grown in a 48-sized pot, and in the border not less than half a dozen should be planted in a group. Employed as a single or double line, it also produces a striking bit of colouring. The bulbs should be planted in autumn four inches deep, the distance between being not more than three inches. Any ordinary garden soil will grow this flower, and it is advisable to allow the bulbs to remain undisturbed for several years, as the effect will be the greater in each succeeding spring.
CROCUS
This brilliant harbinger of spring will thrive in any soil or situation, but to be brought to the highest possible perfection it should be grown in an open bed or border of deep, rich, dry sandy loam. The bulbs should be planted during September, October, and November. If kept out of the ground after the end of the year they will be seriously damaged, and however carefully planted, will not flower in a satisfactory manner. Plant three inches deep in lines, clumps, or masses, as taste may suggest, putting the bulbs two inches apart. If convenient, let them remain undisturbed two or three years, and then take them up and plant again in well-prepared and liberally manured soil. A bed of mixed Crocuses has a pleasing appearance, but in selecting bulbs for the geometric garden it is more effective to employ distinct colours, reserving the yellow for the exterior parts of the design to define its boundaries, and using the blue and the white in masses and bands within. In districts where sparrows attack the flowers, they may be deterred from doing mischief by stretching over the beds a few strands of black thread, which will not interfere with the beauty of the display, and will terrify the sparrows for a sufficient period to save the flowers.
The named varieties are invaluable for pot and frame culture, and to force for decorative purposes; for though the individual flowers are short-lived, the finest bulbs yield a long succession of bloom, and in character Crocuses are quite distinct from all other flowers of the same early season. When grown in pots and baskets, the bulbs should be placed close together to produce a striking effect. A light, rich soil is desirable, but they may be flowered in a mixture of charcoal and moss, or in fibre, or moss alone. When required in quantity for ornamental baskets and similar receptacles, it is wise to plant them in shallow boxes filled with rotten manure and leaf-mould, and to lift them out separately, and pack them when in flower in the ornamental baskets. A perfect display of flowers in precisely the same stage of development can thus be secured, and successional displays may follow as long as supplies remain in the boxes.
CROWN IMPERIAL
Fritillaria imperialis
A noble plant which needs a deep, rich, moist soil, and an open situation, to insure the full degree of stateliness, but it will make a very good figure in any border where it can enjoy a glimmer of sunshine. There are several distinct varieties, the flowers of which range in colour from palest yellow to the deepest shade of orange and reddish buff, and there are others which have variegated leaves. They should be planted in autumn eighteen inches apart, allowing from four to six inches of soil above the crowns.
CYCLAMEN
Although it is advisable to raise Cyclamens from seed every year, occasions arise when it is necessary to store the bulbs for a second season, and the best method of treating them during the period of rest must be considered. As the production of seed weakens the corms, preference should be given to those which have not been subjected to this tax on their energies.
At the close of the flowering season the bulbs should be gradually reduced to a resting state by withholding moisture. When the foliage turns yellow the pots may be laid on their sides in a cold frame, if available, or in any other convenient place where they will not be forgotten, until about the middle of July. They should then be placed upright, and have a supply of water. After fresh growth has fairly commenced, shake the bulbs out of the pots, remove most of the old soil, and re-pot in a compost consisting of mellow turfy loam and leaf-mould, with a sufficient admixture of silver sand to insure drainage. The corm should be so placed in the pot as to bring the crown about level with the rim, and every care must be taken to avoid injuring the young roots. Place the pots in a close frame for a few days, after which ample ventilation should be given to maintain a robust condition. The lights may remain constantly open until there is danger from autumn frosts. Specimens that show a great number of flower-buds should be assisted occasionally with weak manure water.
_C. Coum_ and _C. europæum_ are rarely well grown, for although quite hardy, the climate of this country does not suit them in their season of flowering, which is the early spring. The cool greenhouse is the safest place for them, except in sheltered spots, where they may be planted out on a border of peat, or amongst ferns in a rockery. When grown in pots, light turfy loam and peat in equal quantities, with a fourth part of cow-manure and a liberal addition of sand, will form an excellent compost for them. The pots should never be exposed to the drying action of the sun or wind, but should be plunged to the rim in coal-ashes. The best time for potting or planting them is September or October.
Instructions on raising Cyclamens from seed will be found at page 256.
DAFFODIL—_see_ NARCISSUS, _page_ 344
DOG’S-TOOTH VIOLET
The red and white varieties are as hardy as any plant in our gardens, and by their neat habit and elegant leaves and flowers they are admirably adapted to plant in quantities in the front of a rockery, in either peat or sandy loam and leaf-mould. They are equally suitable for edging small beds in gardens where spring flowers are systematically grown; in fact, they are true ‘spring bedders.’ Autumn is the proper time to plant the bulbs. But Dog’s-tooth Violets are also worth growing in pots, especially where an unheated ‘Alpine house’ is kept for plants of this class. Several bulbs may be put in a pot of the 48-size.
FERRARIA—_see_ TIGRIDIA, _page 350_
FREESIA
The singularly graceful form, wide range of beautiful colours, and delicious perfume of this flower have made it an immense favourite; and happily there is no Cape bulb which can be grown with greater ease in the frame or cool greenhouse. One characteristic is very marked, and it is the disproportion between the small bulb and the fine flowers produced from it.
Procure the bulbs as early in the autumn as possible, and lose no time in potting them. Any light rich soil will answer, but that which suits them best is composed of two parts of loam, one of leaf-mould, and one of peat, with enough sand or grit added to insure drainage. Commence with pots of the right size, for the roots are extremely brittle, and there must be no risk of injuring them by re-potting. The 48-size will accommodate several bulbs. Place under a south wall, and cover with leaf-mould until top growth commences, and then remove the covering.
At the end of September transfer the pots to a cold frame, and when the plants attain a height of four inches, support them with neat sticks, which should not be inserted too near the bulbs. Watering will require judgment, for too much moisture turns the foliage yellow. When the pots are full of roots, liquid manure twice a week will be helpful.
After the blooming season has passed, encourage the foliage to wither by withholding water. The roots may be stored away in their own pots until the following August.
FRITILLARIA
Fritillarias produce bell-shaped flowers, varying in colour, but generally of a purplish tint, and beautifully spotted. They thrive in a good deep loam, but may be grown in almost any soil, and do well under the shade of trees. They are quite hardy, and, like most other bulbs, should be planted in autumn. Fritillarias are occasionally grown in pots kept in a cold frame, but they will not endure forcing in the least degree, and the mixed border is the best position for them. These flowers make a charming ornament when grown in bowls filled with moss-fibre.
GLADIOLUS
The Gladiolus is adapted for many important uses and it associates admirably with Dahlias, Hollyhocks, Pyrethrums, and Phloxes in the furnishing of clumps on the lawn and in the mixed border. It is perfectly in harmony with surroundings when planted in American beds or in the shrubbery. For supplying cut flowers it is invaluable, as they retain their freshness in a vase for many days, and a plentiful supply should be grown in reserved spots expressly for this purpose.
Culture in Pots.—The early-flowering varieties are of especial value for decorating greenhouses and conservatories during spring and early summer. The corms of these Gladioli are small, and a 32-sized pot will accommodate several. The soil should be decidedly rich, and it must be porous, because water has to be given freely when the plants are in full growth. Pot the corms in autumn, and cover with leaf-mould until the roots are developed, when successive batches can be brought forward and gently forced for a continuous supply of elegant flowers during April and May. A mild temperature of about 55° is quite sufficient for them.
Culture in the Open Ground.—The autumn-flowering Gladioli are grown in the open ground, and preparations should begin well in advance of planting time. Almost any soil can be made to answer, but that which suits them best is a good medium, friable loam with a cool rich subsoil, and each grower must decide for himself how far this is within reach naturally, or can be secured by resources at command. Thus, a light soil may be made suitable by placing a thick layer of rotten cow-manure a foot below the surface, and a heavy, retentive loam can be reduced to the proper state by the admixture of lighter material. On the surface spread a liberal quantity of manure and dig it in, leaving the soil in a rough state to be disintegrated by frosts. Before the planting time arrives it is worth some trouble to free the ground from wire worms, or they will play havoc with the growth just as it is appearing above ground. Potatoes serve admirably as traps for these pests.
Gladioli are peculiarly liable to injury from wind, so that a sheltered, but not a shaded, position should, if possible, be chosen for them. The time of planting depends partly on the district, partly on the season; but the soil must be in suitable condition and fine weather is necessary. From the middle of March to the middle of April should afford some suitable opportunity of getting the bulbs in satisfactorily. Give the land a light forking, not deep enough to bring up the manure, and make the surface level. The rows may be twelve or eighteen inches apart; we prefer the greater distance, because of the convenience it affords in attending to the plants when growing; nine inches is sufficient space in the rows.
There are two methods of putting in the bulbs, each of which has advocates among practised growers. One is to take out the soil with a trowel to the depth of six or seven inches for each corm, then insert about two inches of mixed sand and powdered charcoal or wood ashes; lay the root upon it, and carefully cover with fine soil. If that process is considered too tedious, draw a deep drill with a hoe, and at the bottom put the light mixture already named; place the roots at regular distances upon it, and lightly return the top soil. The operation should be so performed as to leave the crown of the corm four inches below the surface. When planting is completed, give the bed a finishing touch with the rake.
An eminent grower strips off the outer coat or skin of each bulb before planting to ascertain that there is no disease; and this cannot otherwise be discovered. No doubt the procedure prevents the bed from showing blanks, but that object can be more safely attained by growing a reserve in pots. There is, however, another practice which possesses very decided advantages, and it is to break the skin at the crown of the bulb to allow the foliage free exit. The skin is so tough that it is frequently the means of distorting the plant in its attempt to force an opening.
The bed for a time needs little attention, except to keep it free from weeds, and this is best done by hand. When the shoots reach about a foot high, tying must be resorted to in earnest. The most effectual plan, of course, is to put a separate stake to each plant, and for exhibition specimens this is certainly advisable. But rows can be secured by a stake at each end, with two or three strands of strong material carried across, to which each flower must be tied. Whatever method is adopted, care should be taken to avoid cutting the plant, while holding it secure from damage in a high wind. Let the material which is placed round the flowering-stem be soft and wide, such as list, which answers admirably.
Water must be freely and regularly given during dry weather, either in the morning or in the evening; and a mulch of old manure spread over the bed will prevent evaporation, and save the ground from caking hard.
Another important matter is shading. For ordinary purposes this is not essential; but as it very much lengthens the duration of the flower, it is worth attention on that ground alone, and for exhibition it is indispensable. Whether shading is provided by separate protectors made expressly for the purpose, or by home-made contrivances of canvas or wood, the point to be quite certain about is security, or an accident may wreck well-grounded hopes.
The lifting and storing of the corms affect the quality of the next year’s flowers so much that it is important to accomplish lifting at the most suitable time, and the storing in the best manner. By the middle or end of October, on some fine day, take up the roots, even if the foliage be still green; tie a label to each variety, and hang them in some airy place until they can be cleared of soil and leaves. Remove each stem with a sharp knife, and lay out the bulbs to dry for another fortnight. They can then be stored in paper bags or in boxes on any dry shelf which is safe from vermin and frost.
An article on the culture of the Gladiolus from seed will be found on page 267.
GLOXINIA
Gloxinias may be had in bloom almost all the year by judicious management. When required for early flowering, those that start first should be selected and carefully shifted into other pots, and be kept near the glass, as they depend much on light for rapid and luxuriant growth. A moist atmosphere, with the temperature about 60° to 65°, greatly facilitates the growth of Gloxinias, but they may be grown well in greenhouses or in pits heated by hot water. The most suitable soil is a light fibrous loam, combined with a little peat and silver sand. Manure water during the growing period twice a week is helpful, but it should be discontinued when the flowers show colour. The plants love shade, and at no time should suffer from drought. Storing Gloxinias for their season of rest, _i.e._ the winter, must be carefully attended to, as losses frequently occur during this stage. It is also important that the plants should not be ‘dried off’ too quickly; place them in a light, airy position, and by a gradual reduction of moisture the leaves will fall off naturally. The bulbs may then be stored away on a shelf, in an even temperature of about 50°, each bulb being closely surrounded by cocoa-nut fibre and peat in equal parts to prevent excessive dryness, which, like too much damp, often causes the loss of the bulb.
Besides growing the same plants from year to year, it is always desirable to have a fresh stock coming on, as the old bulbs may deteriorate after two or three years. This can easily be managed by successive sowings of seed, as advised at page 268.
HEMEROCALLIS—_see under_ LILIES, _page 343_
HYACINTH
One of the most valuable characteristics of the Hyacinth is the ease with which it can be flowered in a variety of ways by very simple modes of treatment. It may be employed as a hardy, rough-weather plant for the garden border, or as a grand exhibition and conservatory flower. The bulbs may be planted at any time from September to the middle of December, with the certainty of their blooming well, if properly cared for; but the prudent cultivator will plant them as early as possible in the autumn, and so manage them afterwards as to secure the longest period of growth previous to their flowering. They can be forced to flower at Christmas, but the more slowly the flowers are developed the finer in the end will they be. To obtain good bulbs is a matter of the utmost importance, and it may be useful here to remark that the mere size of a Hyacinth bulb is no criterion of its value—nor, indeed, is its neatness of form or brightness of appearance. The two most important qualities are soundness and density. If the bulbs are hard and heavy in proportion to their size, they may be depended on to produce good flowers of their kind. The bulbs of some sorts are never large or handsome, while, on the other hand, many others partake of both these qualities in a marked degree.
One other matter in general relating to the treatment of Hyacinths needs to be referred to. Harm has often been done by the practice of massing the flowers, whether in pot groups or in garden beds, without consideration of colour harmonies. Yet no other bulbous flower offers such a wide choice of delightful colours, or is so eminently adapted to artistic blending, as the Hyacinth. By eschewing the dull blues and allied shades and by bringing into association exquisite tones of mauve, pink, apricot, salmon, pale yellow, rich lilac, bright red, &c., it is easy to demonstrate that there are possibilities in Hyacinths which may never have been suspected before. The following are a few of the charming blends which may be made, and will especially appeal to those who grow Hyacinths indoors: (i) Apricot, cream, and pale blue; (2) cream, pale pink, and rose-pink; (3) bright pink and pale blue; (4) bright red, rich blue, and pure white; (5) rose-pink and rich blue; (6) pale yellow and rich blue; (7) deep mauve and pale mauve; (8) cream and pale blue; (9) bright blue shades (dull, washy, and nondescript blue, purple, and violet tints must be avoided); (10) blush pink and rose-pink; (11) apricot and cream; (12) pale lavender, cream, and apricot. These examples will show that charming effects can be secured either with two or with three varieties. Colour-grouping may also be carried out in the garden, but in this case great care must be exercised to get varieties of clear, bright hues which flower at the same time, such as Inimitable Bedding Hyacinths. Modern taste further dictates that the bare soil shall be hidden, and this end is best served by providing a groundwork of dwarf plants, such as Daisies, Forget-me-nots, double white Arabis, and mauve Aubrietia. Another course is to mix Hyacinths with Daffodils of the Chalice or Star section; there is no better variety than Sir Watkin, but others may be used.
