CUCUMBER

Cucumis sativus The Cucumber is everywhere valued. Its exceeding usefulness explains its popularity, and happily the plant is of an accommodating character. In large establishments, Cucumbers are grown at all seasons of the year; in medium-sized gardens, summer Cucumbers are generally deemed sufficient, and there



is no difficulty in growing an abundant and continuous supply of the finest quality. The winter cultivation demands suitable appliances and skilful management; but a very small house, with an efficient heating apparatus, will suffice to produce a large and constant supply, and therefore winter Cucumbers need not be regarded as beyond the range of practice of any ordinary well-kept garden. Frame Cucumbers are the most in demand, and the easiest to grow. The very first point for the cultivator is to determine when to begin, for the rule is to begin too early, and to waste time and opportunity in consequence. We will suppose the Cucumbers are to be grown in a two-light frame, for which will be required four good cartloads of stable manure. This should be put in a heap three weeks before the bed is made up, and the bed will have to last until the season is sufficiently advanced to sustain the heat without any further fermentation. Considering these points, it will be understood that it is a far safer proceeding to begin the first week in April than the first week in March, and unless the way is clearly seen, the later date is certainly preferable, for it reduces to a minimum the conflict with time in the matter of bottom heat. Make up the heap; then, early in March, turn it twice, and at the end of the month prepare the bed, firming the stuff with a fork as the work proceeds, but taking care not to tread on the bed. Put on the lights and leave the affair for five or six days; then lay down a bed of rich loamy soil of a somewhat light and turfy texture, about nine inches deep. It is now optional to sow or plant as may be most convenient. Strong plants in pots, put out at once, will fruit earlier than plants from seeds sown on the bed. But sowing on the bed is good practice for all that, and if this plan is adopted a few more seeds must be sown than the number of plants required, to provide a margin for enemies; any surplus plants will generally prove useful, for Cucumber plants seldom go begging. If it is preferred to begin with plants, the question of providing them must be considered in good time. The seed should be sown at least a month in advance, and should be brought forward on a hot-bed or in a cool part of a stove. Many a successful Cucumber grower has no better means of raising plants than by sowing the seeds in a box or pan of light rich earth, kept in a sunny corner of a common greenhouse, with a slate or tile laid over until the seeds start, and by a little careful management nice thrifty plants are secured in the course of about four weeks. In some books on horticulture a great deal is said as to the soil in which Cucumber seed should be sown. We advise the reader not to make too much of that question. Any turfy loam, or even peat, will answer; but a rank soil is certainly unfit. The object should be to obtain short, stout plants of a healthy green colour; not the long-drawn, pallid things that are often to be seen on sale, and which by their evident weakness seem destined to illustrate the problems of Cucumber disease. Having made a beginning with strong plants on a good bed, the two matters of importance are to regulate the temperature and the watering. In the first instance, it will be necessary to shade the plants a little, but as they acquire strength they should have more light and more air than are usually allowed to Cucumbers. A temperature averaging 60 deg. by night and 80 deg. by day will be found safe and profitable, as promoting a healthy growth and lasting fruitfulness. But the rule must be elastic. You may shut up at 90 deg. without harm, and during sunshine the glass may rise to 95 deg. without injury, provided the plants have air and are not dry at the roots. But it is of great moment that the night temperature should be kept near 60 deg. and not go below it. If the thermometer shows that the night temperature has been above the proper point owing to the heat of the bed, wedge up the lights about half an inch in the evening, and as the season advances increase this supply of night air, for it keeps the plants in health, provided there is no chill accompanying it. As regards watering, the important point is to employ soft water of the same temperature as the frame, and therefore a spare can, filled with water, must be always kept in the frame ready for use, and when emptied should be filled again and left for the next watering. Twice a day at least the plants and the sides of the frame should receive a shower from the syringe. It is better to syringe three times than twice, but this must be in some degree determined by the temperature. The greater the heat, the more freely should air and water be supplied; on the other hand, if the heat runs down, give water with caution, or disaster may follow. In case of emergency the plants will go through a bad time without serious damage if kept almost dry, and then it will be prudent to give but little air. Sometimes the heat of the bed runs out before there is sufficient sun heat to keep the plants growing, but if they can be maintained in health for a week or so, hot weather may set in, and all will come right. But to carry Cucumbers through at such a time demands particular care as to watering and air-giving. As regards stopping and training, we may as well say at once, that the less of both the better. Free healthy natural growth will result in an abundant production of fruit, and stopping and training will do very little to promote the end in view. But there is something to be done to secure an even growth and the exposure of every leaf to light. When the young plant has made three rough leaves, nip out the point to encourage the production of shoots from the base. When the shoots have made four leaves, nip out the points to promote a further growth of side shoots, and after this there must be no more stopping until there is a show of fruit. The growth should be pegged out to cover the bed in the most regular manner possible, and wherever superfluous shoots appear they must be removed. Any crowding will have to be paid for, because crowded shoots are not fruitful. If a great show of fruit appears suddenly, remove a large portion of it, as over-cropping makes a troublesome glut for a short time, and then there is an end of the business; but by keeping the crop down to a reasonable limit, the plants will bear freely to the end of the season. Every fruiting shoot should be stopped at two leaves beyond the fruit, and as the crop progresses there must be occasional pruning out of old shoots to make room for young ones. An error of management likely to occur with a beginner is allowing the bed to become dry below while it is kept quite moist above by means of the syringe. Many cultivators drive sticks into the bed here and there, and from time to time they draw these out and judge by their appearance whether or not the bed needs a heavy watering. To be dry at the root is deadly to the Cucumber plant, and to be in a swamp is not less deadly. It must have abundance of moisture above and below, but stagnation of either air or water will bring disease, ending in a waste of labour. The greenhouse cultivation of the Cucumber for a summer crop only is the most profitable and simple as well as the most interesting of all the methods practised. In many gardens the houses that have been filled during the winter with Geraniums and other plants are very poorly furnished during the summer, and present a most unsightly appearance. Now, it is a very easy matter to render them at once profitable and beautiful, for when clothed with green vines bearing handsome Cucumbers, such houses are attractive and pay their way amazingly well. To carry out the routine properly, the house should be cleared at the end of April, the plants being removed to pits and frames. If possible, make up the beds on slates laid close over the hot-water pipes, and use a bushel or more of soil under each light to begin with. First lay on the slate a large seed-pan, bottom upwards, and on that a few flat tiles, and then heap up a shallow cone of nice light turfy loam. Start the fire and shut up, and raise the heat of the empty house to 80 deg. or 90 deg. for one whole day. The next day plant on each hillock a short stout Cucumber plant, or sow three seeds. Proceed as advised for frame culture, keeping a temperature of 60 deg. by night and 80 deg. by day, with a rise of 5 deg. to 10 deg. during sunshine. Ply the syringe freely, give air carefully, and use the least amount of shading possible. It will very soon be found that by judicious management in shutting up and air-giving, the firing may be dispensed with, and then it remains only to syringe freely and train with care. The plants should not be stopped at all, but be taken up direct to the roof and be trained out on a few wires or tarred string, in the first instance right and left, and afterwards along the rafters to meet at the ridge, and form a rich leafy arcade. The fruits will appear in quantity, and must be thinned to prevent over-cropping. As the plants grow, earth must be added to the hillocks until there is a continuous bed, on which a certain number of shoots may be trained where there is sufficient light for them. It is best to begin as advised above, with the aid of fire heat to start the crop for the sake of gaining time; but if this is not convenient begin without fire heat in the last week of May, and the plants will produce fruit until the chill of autumn makes an end of them, and the house is again required for the greenhouse plants. Winter Cucumbers thrive best in lean-to houses with somewhat steep roofs, as such houses are less liable to chill during cold windy weather, and they catch a maximum of the winter sunshine. In a mild winter, Cucumbers may be grown in any kind of house that can be maintained at a suitable temperature, and the markets are supplied from rough constructions that do duty for many purposes. But in hard weather, the steep lean-to, with bed along the front, and tank to give equable bottom heat, will prove the most serviceable, as it will neither allow snow to lodge on the glass, nor suffer any serious decline of temperature during the prevalence of sharp frost and keen winds. For late autumn supply any kind of house will suffice, but best of all an airy span. A brick pit will answer every purpose from October to March with good management, and fermenting materials will afford the needful heat. In such cases trenches should be provided for occasional renewal of the bottom heat. But a roomy house and a service of hot water justly stand in favour with experienced cultivators, as combining the necessary conditions with convenience of management. For winter culture, plants are raised from seeds and from cuttings. Seedling plants are the most vigorous, but they require a little more time than cuttings to arrive at a fruiting state. For pot culture cuttings are preferable, as only a moderate crop is expected, and quickness of production is of great importance. It is usual to sow the first lot of seeds on the 1st of September, and to sow again on the 1st of October and the 1st of November; after which it is not advisable to sow again until the 1st of February for the spring crop. If the management is good, the first sowing will be in fruit by the time the third batch of seed is sown, say, by the first week of November, and thenceforward throughout the winter there should be no break in the supply. The management of Winter Cucumbers turns upon details chiefly, and will be found in the end to depend rather upon care than skill. The general principles are the same as in growing Cucumbers in frames, the task for the cultivator being to carry them out successfully. Begin by sowing the seed singly in small pots in light turfy loam, or peat with which a fair proportion of sharp sand has been mixed. These pots to be placed in a heat of 70 deg. to 75 deg., and for plants to last long the lower temperature is preferable. As regards the next stage, the plants may be trained up rafters, or spread out on beds, the first being always the better plan where it happens to be convenient. But the prudent cultivator will not be tied to rules; he will cut his coat according to his cloth, and while he has a house of Cucumbers trained to the roof, he will, perhaps, also have a pit filled with plants on beds. To stop severely is bad practice, for vigorous growth is wanted; but a certain amount of stopping must be done to promote an even growth, and to distribute the fruit fairly both in space and time. We have already admitted that in some books on gardening too much has been said about soil. In many places a suitable turfy loam, or a good fibrous peat, may be obtained, and the accidents that have befallen Cucumbers have usually been the result of bad management in respect of heat, water, and air, rather than the use of unsuitable soil. But it must not be supposed that we are careless about this matter. Neither a pasty clay, a sour sticky loam, nor a poor sandy or chalky soil will produce fine Cucumbers. On the other hand, rank manure and poor leaf-mould are both unfavourable materials. There is nothing like mellow loam, which can be enriched and modified at discretion, without going to extremes. Ridge Cucumbers are grown in much the same way as recommended for Vegetable Marrows. They may be put on hillocks or beds, and in either case a foundation of fermenting material is required to insure a crop in the early part of the summer. For a late crop, the natural heat of the soil will be sufficient should the summer prove to be fine, but in a cold season Ridge Cucumbers are disappointing. Of the many methods of growing them, one of the best is to lay out the ground in four-feet beds by taking out the soil to a depth of fifteen inches, and spreading about that depth or more of half-rotted manure, to which may be added any leaves and other litter that may be handy. Cover with a foot depth of good loam. About mid-April sow the seeds in three-inch pots or in boxes and place in a cool greenhouse. After careful hardening, plant out about the third week of May. If preferred, seeds may be sown on the bed early in May. Give the plants the protection of a hand-light should the weather prove unfavourable, and some care will be needed to keep them moving fairly until the season is so far advanced as to allow for the removal of the lights. Put the plants at thirty inches apart down the middle of the bed, and when growing freely, nip out the points once only. A crop of Lettuce may be taken from the beds while the plants are advancing.
