Chapter 17

The Vegetable Marrow will grow in any good soil, and although a tender plant, it is so accommodating that if the seed is sown on a piece of newly dug clay land in the latter part of May, or early in June, the plants will thrive and produce a heavy crop the same season. We put this as an extreme case, but we do not recommend such a careless mode of growing this valuable vegetable. The fact is, it pays better to grow it well than to grow it ill; and in a country where land and labour are costly, and the summer very uncertain, it is best to take such a thing in hand scientifically, and provide for it as many favourable conditions as possible. Three conditions are imperative: a moderate bottom heat from fermenting material; a kindly, loamy soil, quite mellow, in which the roots can run freely; and a sufficiency of water, for this is a thirsty plant. But the excessive use of manure is undesirable, as this only forces a rank growth of foliage at the expense of the fruit.

Frame culture is of some importance, because early Marrows are highly valued at good tables. For this business the neat-growing, small-fruited kinds should be chosen, as they yield a great crop in a small compass. The best place for an early crop of Marrows is a brick pit, with hot-water pipes for top heat, and a bed of fermenting materials for bottom heat. It is no difficult matter to obtain a supply in a house with Cucumbers, but it is better to grow the Marrows apart, as they require less heat and less moisture than Cucumbers. In making up the bed, it is well to employ leaves largely, say to the extent of one-half, the remainder being stable manure that has been twice turned. Such a bed will give a mild heat for a great length of time, and the plants can be put out upon it within three days of its being made up. When grown in a common frame, the arrangements are much the same as advised for the frame cultivation of the Cucumber, the chief points of difference being that Marrows should have less heat and more air. The temperature for Marrows under cover may range from 55° the minimum, to 80° the maximum; the safe medium being about 65° when the weather is cold and dull; running to 80° when strong sunshine prevails, and the plants are growing freely with plenty of air. As for the general management, a bed nine inches deep of good fibrous loam is required, with regular supplies of water of the same temperature as the pits, so that the bed is always reasonably moist, and every evening a slight syringing over the leaves and the walls before shutting up. The training out is a very simple matter. Let the vines run in their own way until they have made shoots eighteen inches long, then nip out the points. After this there must be no more stopping, but occasionally the laterals must be suppressed to prevent crowding. Give air freely at every opportunity, and be careful not to administer too much water, or the blunder will result in a deficiency of fruit.

To grow Marrows in the open air, the best course of procedure is to remove a portion of the top soil, to form a shallow trench four feet wide. Into this carry one foot to eighteen inches depth of half-rotten manure, or a mixture of equal parts of manure and leaves, and cover with the soil that was taken out. This will produce a very gentle hot-bed that will last until the natural ground heat is sufficient to keep the plants in vigorous health. The middle of May is quite early enough to make up the bed, and in the course of two or three days the plants may be put out. Cover with hand-lights or small frames, which on the following day should be tilted at bottom to admit a little air, and if strong sunshine occurs, a Rhubarb leaf may be laid over to subdue the glare upon the young plants. We will suppose these plants to have been raised in a Cucumber frame from seeds sown in April. If plants are not available, sow seeds in patches of two or three on the bed, and cover with inverted large flower-pots, and with a piece of tile to stop the hole. This plan hastens germination. Pots may also be used as protectors if glass frames are not at command, being taken off during the day and put on at night, the hole being left open to give a little air. During bad weather the pots should remain all day over the plants, but as soon as possible must be again taken off to keep the growth short, green, and vigorous. The plants should be put singly down the centre of the bed, three feet apart, and as a matter of course the seeds should be sown at the same distance, and each clump of two or three should be reduced to one when the plants are somewhat forward. It is advisable not to be in a hurry in thinning the plants, for the slugs will probably compel some modification of arrangements, so that sometimes it will be necessary to lift a clump, and divide the plants, to fill up gaps where the slugs have made a clearance. An occasional inspection in the after part of the day, and again in the early morning, will be the best course to keep down the slugs, as they may then be caught and disposed of; but a dusting of soot around each clump will do much to protect the plants against silent marauders. As for after-management, there is no occasion whatever for any stopping or training, but now and then a stout peg may be placed to keep some strong vine in order. The necessity for moisture must not be overlooked. If the ground becomes dry the plants will suffer, but with sufficient moisture they will continue growing and bearing until the frost destroys them. Cut the Marrows when quite young, for not only are they more useful on the table when small and tender, but the plants will bear five times as many as when a few are permitted to attain their full size. The explanation of the case is very simple. The production of the young fruits does not in any appreciable degree exhaust the plants; but when the fruits are allowed to develop, the plant is too severely taxed, and a succession is pretty well brought to a stop. The most delicately flavoured Marrows, as a rule, are the smallest; these when cooked should be served whole, or at most only cut into halves, and of course there is no occasion to remove the seeds.

A YEAR’S WORK IN THE VEGETABLE GARDEN

The following monthly notes are not intended to supersede the detailed instructions on the several kinds of Vegetables which appear in the preceding pages. The present object is to call attention to the work that must be done, and the work that must be prepared for, as the changes of the seasons require and the state of the weather may permit; yet some amount of detail is included. Merely to offer reminders would be to exclude the great mass of amateurs, and the less experienced of practical gardeners, from participation in the advantages of these monthly notes, and to restrict their use to a few practical men who are masters of every detail of the business of gardening. The routine under each month is generally in harmony-with that already recommended, but certain variations of practice are suggested which may prove of service in some districts and under particular circumstances.

A work on gardening demands of the reader the exercise of judgment. If blindly followed, it may prove as often wrong as right; for it is not in the power of the authors to influence the weather in favour of their directions, or to insure to those who may follow their guidance a single one amongst the many conditions requisite to success. Although the times named for certain operations are the best as an average, peculiarities of climate and of season will require some modifications, which each one must discover for himself; and after the seed of any vegetable has been sown it is not always needful to give subsequent reminders of successional sowings. These naturally follow in accordance with the requirements of each particular garden. With such allowances duly made, these notes will, it is hoped, prove thoroughly practical, and tend materially to aid the cultivator in obtaining from the vegetable garden an abundance of everything in its season, and of a quality of which he need not be ashamed.

JANUARY

Work in the garden during the opening month of the year is entirely dependent on the weather, and it is futile to enter on a vain conflict with Nature. When heavy rains prevail keep off the ground, but immediately it will bear traffic without poaching be prepared to take advantage of every favourable hour. Much may be done in January to make ready for the busy spring, and every moment usefully employed will relieve the pressure later on. Survey the stock of pea-sticks, haul out all the rubbish from the yard, and make a ‘smother’ of waste prunings and heaps of twitch and other stuff for which there is no decided use. If properly done, the result will be a black ash of the most fertilising nature, such as a mere fire will not produce. Should the soil be frost-bound wheel out manure and lay it in heaps ready to be spread and dug in where seed-beds are to be made. If the weather is open and dry, trench spare plots and make ready well-manured plots for sowing Peas and Beans. So far as may be convenient, all preparatory work should be pushed on with vigour, and every effort must be made to lay up as much land in the rough as possible; for the more it is frozen through the greater will be its fertility, and the more beautiful, as well as more abundant, the crops.

It is a matter of the most ordinary prudence to be prepared to resist the shock of a severe frost. When this event occurs, many suffer loss because they are not prepared for it. Good brick walls and substantial roofs are needed for the safe keeping of fruits and the more valuable kinds of roots; but when rough methods are resorted to, such as clamping and pitting, there should be a large body of stuff employed, for a prolonged frost will find its way through any thin covering, no matter what the material may be. As there is not much to do now out of doors, it is a good time to look over the notes which were made concerning various crops in the past season, and to attend to the seed list.

Seed sowing should be practised with exceeding caution; but great things may be done where there are warm, sheltered, dry borders, and suitable appliances for screening and forwarding early crops. Under these favourable conditions, we advise the sowing of small breadths of a few choice subjects towards the end of the month; and, this being done, every care should be taken to nurse the seedlings through the trying times that are before them. Such things as tender young Radishes, Onions, small Salads, Spinach, Cabbage, and Carrots never come in too early; the trouble often is that they are seen in the market while as yet they are invisible in the garden. Hedges of Hornbeam, Laurel, or Holly, to break the force of the wind, are valuable for sheltering early borders, and walls are great aids to earliness by the warmth they reflect and the dryness they promote.

The soil for these early crops should be light and rich, and the position extra well drained, to prevent the slightest accumulation of water during heavy rains. Supposing you have such a border, sow upon it, as early as weather will permit, any of the smaller sorts of Cabbage Lettuce, Onion, Long Scarlet Radish, Round Spinach, Cabbage, and Carrot. All these crops may be grown in frames with greater safety, and in many exposed places the warm border is almost an impossibility. Reed hurdles and loose dry litter should be always ready when early cropping is in hand; and old lights, and even old doors, and any and every kind of screen may be made use of at times to protect the early seed-beds from snow, severe frost, and the dry blast of an east wind.

Forcing is one of the fine arts in the English garden. It is an art easily acquired up to a certain point, but beyond that point full of difficulty. Every step in this business is a conflict with Nature, and in such a conflict the devices of man must occasionally fail. A golden rule is to be found in the proverb ‘The more haste the less speed.’ Whatever the source of heat, it should be moderate at first, and should be augmented slowly. The earlier the forced articles are required the more careful should be the preparation for them, and the more moderate the temperature in the first instance. There must be at command a constant as well as sufficient temperature: when a forced crop has made some progress a check will be fatal to success. The beginner should acquire experience with Rhubarb and Sea Kale, then with Asparagus and Mushrooms and Dwarf French Beans, and so on to ‘higher heights’ of this branch of practical gardening.

Artichokes, Globe, are not quite hardy, and must be protected with litter.

Asparagus beds to be heavily manured, if not already done, but the beds need not be dug. Be content to lay the manure on, and the rains will wash the stimulant down to the roots in due time. In gardens near the coast seaweed is the best of manure for Asparagus, and the use of salt can then be dispensed with.

Beans, Broad, may be sown in frames, and towards the end of the month in open quarters. For early crops select the Longpod varieties. Sow on ground deeply dug and well manured.

Cabbage may be planted out at any time when weather permits, provided you possess, or can obtain, the plants; and it is of the utmost importance to secure them from a reliable source, or varieties may be planted which will in a few weeks send up flower-stems instead of forming tender hearts. At every season of the year vacant plots should be kept going with a few breadths of Cabbage. With our variable climate they may be acceptable, even in the height of summer, if there has been a hard run upon other vegetables, or some important crop has failed outright.

Cauliflower may be sown on a gentle hot-bed, or in a pan in the greenhouse, or even in a frame, to make a start for planting out in March or April.

Cress, to be enjoyed, must be produced from a constant succession of small but frequent sowings. All the sorts are good, but different in flavour, and they should be used only while young and tender. Sow at intervals of a few days in pans, as in the case of Mustard, until it is possible to cultivate in the open air, and then give a shady position during summer on a mellow and rather moist soil.

Cucumbers are never ready too soon to meet the demand in early spring. They are grown in houses more or less adapted to their requirements, and also in frames over hot-beds. At this time of year, however, frames are somewhat troublesome to manage, and in trying weather they are a little hazardous, although later in the season there is no difficulty whatever with them. For the present, therefore, we shall confine our remarks to house culture. Almost any greenhouse may be made to answer, but the work can be carried on most successfully and with the greatest economy in houses which are expressly constructed for Cucumbers. For winter work a lean-to, facing south, possesses special advantages. But for general utility, if we had to erect a building on a well-drained soil, it should be dwarf, sunk three feet in the ground, with brick walls up to the eaves, and lighted only from the roof. Such a structure is less influenced by atmospheric changes than a building wholly above ground. The size, of course, is optional; and quite a small house will supply an ordinary family with Cucumbers. But a small house is not economical either in fuel or in labour. A building thirty feet long by twelve feet wide, six feet high at the sides, and eight and a half feet high at the ridge, will not only grow Cucumbers and Melons, but will also be of immense service for many other plants. A division across the middle by a wall rising four feet, surmounted with a glass screen fitted to the roof, and finished with a door partially of glass, will greatly augment its usefulness. There should be an alley down the centre four or five feet wide, bounded by walls reaching four feet above the floor. These walls should be nine inches thick for two feet six inches of their height, but for the upper parts the brickwork need only be four and a half inches thick. This arrangement will provide a ledge on the inner side of each wall, and the main walls should also have ledges corresponding in height, on which to lay slates to carry the soil. To insure drainage, allow a space of about an inch between the slates, and place tiles or an inverted turf over every opening to prevent the soil being washed away. The hot-water pipes will be in chambers immediately beneath the plants. Openings in the alley walls, fitted with sliding doors, will admit the heat direct into the house whenever it may be desirable. Ventilation should be provided for under the ridge at each end, as well as in the roof. In such a house it is easy to grow Cucumbers all the year round, except, perhaps, in the dead of winter, when the short, dark days render the task difficult, no matter how perfect the appliances at command. The division in the centre will be found valuable at all times, and especially when one set of plants is failing; for another set can be brought into bearing exactly when wanted. But whatever the structure may be, the mode of culture remains substantially the same in any case. Now, as to soil, a compost made of mellow turfy loam and leaf-mould in equal parts will be effective and sweet. In the absence of leaf-mould, use two parts of loam and one of thoroughly decayed manure with a few pieces of charcoal added. Sweetness is not absolutely necessary for success, but nevertheless we like to have it, so that a visit to the Cucumber-house may be a source of pleasure. This it cannot be if rank manure has been used. Raise the seed singly in small 60-pots, and sow enough, for however good the seed may be a proportion will almost certainly fail from some cause at this critical period. Give the plants one shift into the 48-size, to keep them going until they are ready for putting into the beds. Cucumbers grow with great rapidity, and should never know a check, least of all by starvation. Upon the slates make as many heaps of soil as are required, and in the centre of each heap put one plant. As the roots extend, add more soil until the heaps meet and finally become level with the top of the brickwork. This treatment will supply food as the roots develop, and help to maintain the plants in bearing for a long period. Stout wires running parallel with the length of the house, a foot below the glass, will carry the vines. Temperature should never fall below 60° at night; but as the season advances, if the thermometer registers 90° on sunny days, no harm will be done, provided the roots are not dry, and the air be kept properly moist by plying the syringe. On dull days one good sprinkling over the foliage will suffice, and it should be done in the morning. In warm sunny weather, however, two or three syringings will be beneficial; but the work must not be done so late as to risk the foliage being wet when night comes on. There will be occasions when it may be advisable to avoid touching the leaves with water, if there is no probability of their drying before nightfall. In such a case the moisture can be kept up by freely sprinkling the floor and walls. Cucumbers cannot thrive if they are dry at the roots, but although there should be no stint of water, it must be given with judgment; and it is of the utmost importance that the drainage should be effectual, for stagnant water is even more injurious than a dry soil. A few sticks placed in various parts of the bed, reaching down to the slates, will serve as indicators. Draw and inspect them occasionally, and a pretty correct idea of the condition of the soil will be obtained. The water should be of the same temperature as the house; if applied cold the plants will sustain a serious check. In the event of the bed falling somewhat below the proper temperature, the water may with advantage be a few degrees higher than usual.

Horse-radish should be planted early, to insure fine roots for next Christmas beef.

Leek.—Those who wish to produce stems of superb size and beautiful texture must sow in heat during this month or early in February, for a longer period of growth is requisite than for ordinary crops. When sufficient root growth has been made, transplant into larger pots, and in due course transfer these to a frame where the plants may be gradually hardened off for putting out into specially prepared trenches in April.

Lettuces will soon be in demand, and the early hearts will be particularly precious. Sow a few sorts in pans, in frames, or on gentle hot-beds, to be ready for planting out by-and-by.

Melon.—Although the Melon is a fruit, its culture naturally forms part of the routine of a vegetable garden. Up to a certain point it may be grown in the same house with Cucumbers; but after that point is reached, the two plants need widely different treatment. Cucumbers are cut when young, and must be grown in a warm and humid atmosphere from beginning to end. Melons need warmth, and at the commencement moisture also; but the fruit has to be ripened, and after it is set dry treatment becomes essential for the production of a rich flavour with plenty of aroma. In large gardens, three crops of Melons are usually grown in the same house in one season. A light soil is advisable at the beginning of the year, but later in the season a heavier compost may be employed. For the first sowing select an early variety, and at the beginning of this month put the seed in separate pots. Re-pot the plants once, and they will be ready for the beds by the first week of February. Melons from this sowing should be fit for table in May, which is quite as early as they can be produced with any sugar in them. Until the fruits begin to swell the treatment advised for Cucumbers will suit Melons also. Afterwards the watering will need careful management. It would be an advantage if the fruit could be finished off without a drop of water from the time they are about two inches in diameter, but the hot pipes render it almost impossible. Still, water must not be given more frequently than is actually necessary to keep the plants going, and when it is applied let there be a thorough soaking. At the same time ventilation will demand constant attention, and, provided the temperature can be maintained, it is scarcely possible to give air too freely. In the early stage of growth, and in mild weather, if the thermometer registers 65° at 9 P.M., the cultivator may sleep peacefully so far as Melons are concerned. As the season advances, the temperature may be increased to 70° by night, and 75° to 90° by day. With reference to stopping, it may be sufficient to say that it is a waste of energy to allow the plant to make a large quantity of vine, which has afterwards to be cut away. By judiciously pinching out the shoots, the plant can be equally spread over the allotted space. The flowers must be fertilised, and in this respect the treatment differs from that advised for Cucumbers. The practice has the advantage of allowing the fruits to be evenly distributed over the vine, and from four to six, according to the size of the variety, will be enough for each plant to ripen.
