Part 12 (1/2)

Immediately two or at most four leaves are formed either p.r.i.c.k off into other pans or boxes, or transfer singly to thumb pots, and as a rule the pots will be found preferable. The soil for these pans or pots should be stored in the greenhouse a few days in advance of the transfer, so that the compost may acquire the proper temperature and save the plants from an untimely check. In small houses place the plants near the gla.s.s that they may remain short in the joint, but on cold nights they must be taken down to avoid injury from fluctuations of temperature. In large houses, where the light is well diffused, there is no need to incur this trouble, for the seedlings will do equally well on the ground level. In due time s.h.i.+ft into six-inch pots, from which they can go straight to borders, or into a larger size if they are to be fruited in pots. About fourteen weeks will be required to prepare the plants for borders in the winter season, but a shorter period will suffice in spring and summer.

Plants from an August or September sowing will not mature fruit in much less than six months, while a March sowing will yield a return in four months or less. A great deal depends on the character of the season, and more on skill and attention. Those who sow in January or February should sow again a fortnight later, and onwards until the end of April, according to requirements. For winter supplies a first sowing may be made in June, in a cold frame, and prepared for transfer to fruiting pots in September.

==Treatment of Soil.==--In the first instance there need be no anxiety about soil. Any fairly good sandy loam will answer for the seed-pans, and if too stiff it may be freely mixed with sharp sand or the sifted sweepings from roads and gravel walks. A fibrous loam, cut from a rich pasture, and laid up in a heap for twelve months, will, with an addition of wood ashes and grit, make an ideal soil for pots or borders. As the plants advance, leaf-mould or thoroughly decayed manure in moderate quant.i.ty should be supplied; but, instead of incorporating it with the loam in the usual way, it will be found advantageous to place the manure immediately above the crocks, and the roots will find it at the right time. But the quant.i.ty of manure must not be overdone, especially in the earlier stages of growth, because excessive luxuriance neither promotes fruitfulness nor conduces to early ripening. After the fruit has set, a mulch of decayed manure will aid the plants in finis.h.i.+ng a heavy crop.

Manure which is only partially fermented will not do at all. The ammonia it liberates exerts so deadly a power that the plants are quickly scorched.

In its demand for potash the Tomato closely resembles the Potato, and of the two the former is the more exacting. So quickly does this crop exhaust the soil, that in small houses it is usual to take out the earth to a depth of fifteen or eighteen inches every second or third year, and replace it with virgin loam. Others grow the Tomatoes alternately in the bed and in pots, but this is only a partial remedy. Constant dressings of farmyard or stable manure result in the formation of humus, which, as it becomes sour, has to be sweetened by the solvent influence of lime.

The chief objection to the use of stable manure, however, even when well rotted, is that it induces a free growth of foliage instead of promoting an early development of fruit. The most enduring method is that which is based on chemical knowledge of the const.i.tuents of the soil, and the relation which the plant bears to it. One of the most successful growers for the London market almost entirely avoids the use of stable manure, and he is able, by applications of nitrate of potash, dissolved bones, and the occasional use of lime, to grow splendid crops in the same houses year after year.

All the conditions which answer for border work are applicable to pots, and a limited number of plants brought forward in succession will supply the requirements of a small household from early spring until near Christmas. The pot system is conducive to free setting and to early ripening, and for these reasons it is worth attention. The plants should be kept short in the joint by frequent s.h.i.+fts until the twelve-inch pot is reached, and this size will accommodate two cordons or one plant having two branches, each of which will require a separate stake for its support. Plunging the pots can be adopted to save labour in watering.

==Temperatures.==--No advantage is to be gained by attempting to force Tomatoes in a higher temperature than is consistent with healthy progress, although in winter there is great temptation in the direction of overheating. Full time for development in moderate heat will bring stout joints, and impart a vigorous const.i.tution that materially aids the plants in resisting the insidious attacks of disease. The waning autumn and dull winter days are the most troublesome periods of management, and it is remarkable that of two days equal in duration and apparently in other conditions, the autumnal appears to be less favourable than the spring day. But if, on the one hand, a high temperature is injurious, a low temperature must be avoided; although for a time it may not appear to be harmful. A temperature of 60 or 65 suits the seed-pans, and after transfer to pots and the roots have become established, the thermometer should not register less than 55 during the night. It may rise 10 by means of fire heat in the daytime, and during bursts of suns.h.i.+ne another 10 or 15 will be quite safe, always a.s.suming that the roots are not dry, and that the plants have free ventilation.

==Watering.==--The judicious administration of water forms an important feature in the culture of the Tomato. The plant is too succulent to endure drought with impunity, and it is mere folly to toy with the water-can. Saturate down to the roots, and then leave the plants alone until more water is wanted. No hard and fast rule can be stated as to frequency. It depends on the condition of the soil, the period of the year, and the age of the plants. Borders and soil for pots should be made sufficiently moist in advance, so that watering will not be necessary immediately after the plants are transferred. The prevalent opinion that excessive watering generates disease is not confirmed by our experience. Of course the watering should not be excessive for many reasons, but the diseases which are often attributed to over-watering are the result of atmospheric mismanagement.

==General Treatment.==--Authorities are not agreed as to whether branched plants or simple cordons yield the better results. In our judgment the single stem deserves preference, and it is now more extensively grown than any other form, although plants having two branches are almost equally popular. Certainly the cordon can be managed with extreme ease; it is admittedly the earliest producer, and there is a general consensus of opinion that the fruit it produces is unsurpa.s.sed in size and quality. The doubtful point is quant.i.ty, but even here the difference, if any, is too trifling to be worth the consideration of private growers. Cordons are formed by removing the laterals as fast as they appear, and when the fruit has set, or the requisite height is attained, the top is also pinched out.

The s.p.a.ce allowed for each plant varies greatly, especially among growers for market. Under gla.s.s every branched Tomato should be allowed at least three feet each way. For cordons we advocate a distance between the rows of three feet, and a s.p.a.ce of two feet in the row is not too much. The stems require support of some kind, and stakes are preferable to string; but of course the stems may be secured to wires whenever it is convenient to run the plants immediately under the gla.s.s.

Another point upon which authorities differ is the extent to which Tomatoes should be denuded of their foliage. Some growers condemn the procedure entirely; others reduce their plants to skeletons. Both extremes are objectionable, for when all the leaves are permitted to remain there is delay or partial failure in colouring the fruit, and the almost entire removal of foliage checks the root action injuriously. In practice it answers well to wait until the fruit has set, then by pinching out the leading point of each leaf, commencing at the bottom, ripening and colouring are promoted, and the health of the plant remains unimpaired.

In dull weather, and especially in short days, a difficulty is sometimes experienced in setting the fruit, particularly the first bunch. After fruit has begun to swell on one bunch, the remainder set with comparative ease. A rather higher temperature than usual combined with free movement of the atmosphere is generally sufficient to insure fertilisation. If a.s.sistance is necessary, however, water the plants early in the afternoon, and close the house rather before the usual time. The warm atmosphere will develop plenty of pollen, and a gentle shaking of the flower bunches with a slight touch from a hazel twig will liberate visible clouds, which will effectually set the fruit. Another method is to lift a flat label or paper knife against the flowers. The label becomes covered with pollen, and by gently touching each flower with a slight upward pressure a great number can be fertilised in a few minutes. A soft brush pa.s.sed over the flowers daily has the same effect.

Plants in the open ground need no such attention if they are in good health and the season is at all genial. When a bunch of flowers contains one that is fasciated or confused, the flower should be pinched out to prevent the formation of large and ugly fruit. The remainder of the bunch will be the finer for its absence.

==OUTDOOR CULTURE.==--For the open ground it is important to choose a variety that ripens early. The plants should be vigorous, and they must be carefully hardened before they are put out. Sow the seed in heat in February or March, and when large enough transfer the seedlings to single pots until wanted. Every effort should be made to avoid giving the plants a check, and if room is available they may be potted on to the six-inch size and allowed to form one truss of bloom before planting out, thus saving valuable time. The end of May is usually the right time for transfer to the open, but Tomatoes will not endure a keen east wind or nipping frost. During the prevalence of unfavourable weather it is advisable to wait a week or more rather than risk the destruction of the plants. When the temperature appears to be fairly reliable, put them into holes a foot deep and eighteen inches across, filled with light soil not too rich. For a few nights until the roots take hold slight protection should be at hand to a.s.sure safety; Sea Kale pots answer admirably, and are easily placed in position. In addition to beds all sorts of places are suitable for Tomatoes, such as under warm palings or walls, on sloping banks and in sheltered nooks, where they will thrive and yield valuable fruit. Stout stakes are required and should be promptly provided. Pinch out the lateral shoots, and as soon as the fruits commence to colour some of the largest leaves may be partially removed. Early in August nip out the tips of the leaders in order to encourage ripening. Thus in the open garden a supply of this delicacy may be insured for part of the year equal in quality to fruit which is grown under gla.s.s. (=See also page 181=.)

==The diseases of the Tomato== are dealt with in the chapter on The Fungus Pests of certain Garden Plants.

==TURNIP==

==Bra.s.sica Rapa==

The Turnip is not a difficult garden crop; indeed, the simplest management will produce an ample supply, and any fairly good ground will suffice for it. But whatever is worth doing is worth doing well, and a gardener may be pardoned for taking an especial pride in producing a sufficiency of handsome and tender Turnips. The great point is to insure a succession through a long season, or, say, the whole year round, for Turnips are always in request, and at certain periods of the year delicate young roots are greatly valued for the table.

The finest Turnips are grown in deep, sandy loam, kept in a high state of cultivation. Useful Turnips may be grown on any soil, but a handsome sample of the finest quality cannot be produced on heavy clay or thin limestone. In common with other fast-growing plants of the cruciferous order, Turnips must have lime in some form, and in many gardens it will occasionally be necessary to give a dressing of lime in addition to the ordinary manure. Superphosphate, bone, and old plaster or mortar from destroyed buildings, are all valuable in preparing the soil for this crop.

==Times of Sowing.==--An early crop of small bulbs may be grown by sowing in January on a very gentle hot-bed as prescribed for early Radishes, and it may be well to add, that in an emergency white Turnip Radishes may be made to take the place of Turnips, both to flavour soups and to appear as a dish in the usual way. Fast-growing Turnips may be sown on a sheltered warm border in February and March, to be carefully watched and protected when unkind weather prevails. In April and May sowings should be made consistently with the probable wants of the household, but the May sowings should comprise two or three sorts in the event of hot dry weather spoiling some of them.

The princ.i.p.al sowings for autumn and winter supplies are made in June and July, but seed may also be sown in August. Ground from which some crop, such as Peas, has just been cleared generally needs little preparation beyond breaking the surface with a hoe, followed by a good raking. Thin the plants early and let them stand finally at six to nine inches apart in the rows. For late crops seed is often sown broadcast, the roots being pulled as they mature.

==General Culture.==--It is advisable to sow Turnips in drills on a fine tilth, and it is an advantage to have a sufficiency of some stimulating manure near the surface to hurry the growth of the young plant, for the danger of fly belongs to the seed-leaf stage. Generally speaking, the Turnip fly does but little harm in gardens; but where it is much feared, the seed should be sown in prepared drills to encourage a quick growth.

Draw the drills twelve to fifteen inches apart, three inches deep, and about the same width, and almost fill them with rotten manure, or with a mixture of earth and guano, or wood ashes; cover this with a little fine soil to prevent injury to the seed; then sow, and lightly conceal the seed with earth as a finish. If the ground is sufficiently moist, growth will commence almost immediately, and the plant will come up strong, and very quickly put forth rough leaves. In the general management more depends on timely and judicious thinning than upon any other point. If Turnips are not well thinned, so that each plant can spread its green head unimpeded by the leaves of a neighbour, a good growth cannot be expected; and thinning by the hoe should be commenced as soon as the rough leaves appear. The operation must be repeated until the plants are at a suitable distance, and then comes the process of singling, which should be done by hand. It will be found that in many cases two or three little plants stand together looking like one. There must be only one left at each station, and that should be the shortest. The distances may vary from four to ten inches, according to the vigour of the variety and the kind of Turnips required. An easy and profitable plan is to allow a certain number of bulbs to swell to supply young Turnips, and, by drawing these, leave room for the remainder of the crop to attain its proper size for storing.

The Turnip likes a light soil, but does not well endure the occasional dryness to which light soils are subject. This fact accounts for many failures of the crop in a hot dry season, for suns.h.i.+ne suits the Turnip, but it must have moisture or suffer deterioration in some way. If, therefore, the soil becomes dry, and there is no prospect of rain, the Turnips should have water, not simply to moisten the surface, but to go to the roots, for frequent watering is not good for the crop, as it tends to spoil the beauty of the bulbs, and promotes a rank leaf-growth which is not wanted. An occasional heavy watering in dry weather will also do much towards the repression of the many enemies that beset this useful root--the jumpers, the grubs, the weevils, and the rest of the vermin will be routed out of their snug hiding-places in the dusty soil when the watering takes place, and the death of many will follow. But so long as the soil is fairly moist at the depth the roots are ranging, there is no need for watering, and the time it would consume may be utilised for other work.
