Earthing up is often performed in a rough way, as though the plant were made of wood instead of the most delicate tissue. The first earthing should be done with a hand-fork, and quite loosely, to allow the heart of the plant room to expand. The result should be a little ring of light earth scarcely pressing the outside leaves, and leaving the whole plant as free as it was before. A fortnight or so later the earthing must be carried a stage further by means of the spade. Chop the earth over, and lay it in heaps on each side of the plant. Then gather a plant together with both hands, liberate one hand, and with it bring the earth to the plant half round the base, and, changing hands, pack up the earth on the other side. Be careful not to press the soil very close; also avoid putting any crumbs into the heart of the plant; and do not earth higher than the base of the leaves. As soon as may be necessary repeat this process, carrying the earth a stage higher; and about a week from this finish the operation.

The top of the plant must now be closed, and the earth carefully packed so high that only the very tops of the leaves are visible. Finish to a proper slope with the spade, but do not press the plants unduly, the object being simply to obtain a final growth of the innermost leaves in darkness, but otherwise free from restraint.

The Bed System answers particularly well for producing a large supply of Celery with the least amount of labour. This method of cultivation is also especially suitable for raising Celery intended to be served when boiled, or for soups. Celery beds are made four and a half feet wide and ten inches deep, the soil which is taken out being laid up in a slope round the outside of the bed, and the bank thus formed may be planted with any quick crop, such as Dwarf Beans. The ground will need to be heavily manured in the same manner as for the trench system. Space the plants six inches apart in single or double lines, as may be preferred, and allow not less than twelve inches between the rows. Water must be given to each row as planted; afterwards the surface to be several times chopped over with the hoe or a small fork, and watering repeated until the plants have made a start. An easy means of blanching is by the use of stiff paper collars as described below; another simple method is to place mats over the tops of the plants when nearly full grown. The bed system is not only economical, but convenient for sheltering in winter, and should have the attention of gardeners who are expected to supply abundance of Celery throughout the winter and spring, for in such cases a large sample is not required, but quality and continuance are of importance.

It is a great point to keep Celery unhurt by frost far on in the winter, and the advantage of growing the late crops on dry light soil, and on the bed system, will be seen in the ease with which the plants can be preserved. On heavy soil Celery soon suffers from frost, but not so readily on a soil naturally light and dry. Moreover, the bed system allows of many methods of protection, with whatever materials are at command. In heavy soil fine crops of Celery for autumn use may be grown, but in consequence of the liability of the plant to suffer by winter damp, it is advisable to plant late crops on the level, and earth up from the adjoining plots in order to keep the roots dry in winter. Another step towards securing a late supply consists in bending the tops on one side at the final earthing, which prevents the trickling of water into the heart of the plant during heavy rain or snow.

Celery for Exhibition.—From the opening paragraph it will be gathered that to produce extra fine specimens of Celery for exhibition very generous treatment of the plants is necessary. Apart from the choice of varieties—and only the finest strains should be considered—four points are of especial importance to the cultivator. The ground must be liberally enriched; at no period should the plant receive a check or suffer for want of water; there must be the closest inspection at frequent intervals to prevent disfiguration of the stalks or leaves by slugs, snails, or the Celery fly; and finally the operation of blanching will need great care and discretion. These points have already been dealt with at some length. But on the question of blanching it may be well to add that in order to insure perfect specimens, free from blemish, artificial means of some kind must be adopted in place of earthing up in the ordinary way. The use of strips of good quality brown paper will prove both simple and effectual. These strips need not exceed a width of five or six inches, fresh bands being added as growth develops. Tie them securely with raffia or twine, making due allowance for expansion of the plant, and when in position carefully draw the soil towards the base.

The numerous enemies of Celery, such as slugs, snails, the mole-cricket, and the maggot, do not seriously interfere with the crop where good cultivation prevails, but the Celery fly appears to be indifferent to good cultivation, and therefore must be dealt with directly. Dusting the leaves occasionally with soot has been found to operate beneficially. It should be done during the month of June on the mornings of days that promise to be sunny. If the soot is put on carelessly it will do more harm than good; a very fine dusting will suffice to render the plant distasteful to the fly. Syringing the leaves with water impregnated with tar has also saved plants from attack. Where the eggs are lodged the leaves will soon appear blistered, and the maggot within must be crushed by pinching the blister between the thumb and finger. Leaves that are much blistered should be removed and burned, but to rob the plants of many leaves will seriously reduce the vigour of growth.

Celeriac, or Turnip-rooted Celery, is much prized on the Continent as a cooked vegetable, and as a salad. In ordinary Celery the stem forms a mere basis to the leaves, but in Celeriac it is developed into a knob weighing from one to five pounds, and the root is more easily preserved than Celery. When cooked in the same manner as Sea Kale, Celery is well known as a delicacy at English tables, and the cooked Celeriac ranks in importance with it, though it affords quite a different dish. The stem or axis of the plant is used, and not the stalks. To grow fine Celeriac a long season is requisite; and therefore it is advisable to sow the seed in a gentle heat early in March, and afterwards prick out and treat as Celery; but after the first stage the treatment is altogether different. For the plantation a light and rich soil is required, and where the staple is heavy, a small bed can easily be prepared by spreading six inches depth of any sandy soil over the surface. The plants must be put out on the level a foot and a half apart each way, and be planted as shallow as possible. Before planting, trim carefully to remove lateral shoots that might divide the stems, and after planting water freely. The cultivation will consist in keeping the crop clean, and frequently drawing the soil away from the plants, for the more they stand out of the ground the better, provided they are not distressed. They must never stand still for want of water, or the roots will not attain to a proper size. The lateral shoots and fibres must be removed to keep the roots intact, but not to such an extent as to arrest progress. When a good growth has been made, and the season is declining, cover the bulbs or stems with a thin coat of fine soil, and in the first week of October lift a portion of the crop and store it in sand, all the leaves being first removed, except those in the centre, which must remain, or the roots may waste their energies in producing another set. The portion of the crop left in the ground will need protection from frost, and this can be accomplished by earthing them over with soil taken from between the rows.

Celeriac is cooked in the same manner as Beet, and requires about the same length of time. The stems, bulbs, or roots (for the knobs, which are true stems, are known by various names) are trimmed, washed, and put into boiling water without salt or any flavouring, and kept boiling until quite tender; they may then be pared, sliced, and served with white sauce, or left uncut to be sliced up for salads when cold.
