Chards are the blanched summer growth of Globe Artichokes, and are by many preferred to blanched Cardoons. In the early part of July the plants selected for Chards must be cut over about six inches above the ground. In a few days after this operation they will need a copious watering, which should be repeated weekly, except when heavy rains occur. By the end of September the plants will have made much growth and be ready for blanching. Draw them together, put a band of hay or straw around them, and earth them up, finishing the work neatly. The blanching will take fully six weeks, during which time there will be but little growth made—hence the necessity for promoting free growth before earthing up. Any Chards not used before winter sets in may be lifted and preserved by packing in sand in a dry shed.
The Artichoke is hardy on dry soils when the winter is of only average severity. But on retentive soils, which are most favourable to the production of fine heads, a severe winter will destroy the plantations unless they have some kind of protection. The usual course of procedure is to cut down the stems and large leaves without touching the smaller central leaves, and, when severe frost appears probable, partially earth up the rows with soil taken from between; this protection is strengthened by the addition of light dry litter loosely thrown over. With the return of spring the litter is removed, the earth is dug back, and all the suckers but about three removed: then a liberal dressing of manure is dug in, care being taken to do as little injury to the plants above and below ground as possible. At the end of five years a plantation will be quite worn out; in somewhat poor soil it will be exhausted in three years. But on any kind of soil the cultivation of this elegant vegetable is greatly simplified by sowing annually, and allowing the plants to stand for two years only, as already advised.
JERUSALEM ARTICHOKE
Helianthus tuberosus
The Jerusalem Artichoke is a member of the Sunflower tribe, quite hardy, and productive of wholesome roots that are in favour with many as a delicacy, and by others are regarded as worthless. It is said that wise men learn to eat every good thing the earth produces, and this root is a good thing when properly served; but when cooked in the same way as a Potato it certainly is a very poor vegetable indeed. It is a matter of some interest, however, that in respect of nutritive value it is about equal to the Potato; therefore, in growing it for domestic use nothing is lost in the way of food, though it needs to be cooked in a different way.
The Jerusalem Artichoke will grow anywhere; indeed, it will often yield a profitable return on land which is unsuitable for any other crop, but to insure a fine sample it requires a deep friable loam and an open situation. We have grown immense crops on a strong deep clay, but it is not a clay plant, because it soon suffers from any excess of moisture. To prepare the ground well for this crop is a matter of importance, for it roots freely and makes an immense top-growth, reaching, when very vigorous, a height of ten or twelve feet. Trench and manure in autumn, and leave the land rough for the winter. Plant in February or March, using whole or cut sets with about three eyes to each, and put them in trenches six inches deep and three feet apart, the sets being one foot apart in the trenches. When the plants appear, hoe the ground between, draw a little fine earth to the stems, and leave the rest to Nature. Take up a portion of the crop in November and store in sand and dig the remainder when wanted, as recommended in the case of Parsnips. The tubers must be dug with a fork by opening trenches and cleaning out every scrap of the roots, for whatever remains will grow and become troublesome in the following season.
Asparagus officinalis
Asparagus is a liliaceous plant of perennial duration, and it demands more generous treatment than the majority of Kitchen Garden crops. Under favourable conditions it improves with age to such an extent as to justify the best possible cultivation. Plantations that have stood and prospered for twenty or even thirty years are not uncommon, but a fair average term is ten years, after which it is generally advisable to break up a bed, the precaution being first taken to secure a succession bed on fresh soil well prepared for the purpose. Plantations are made either by sowing seeds or from transplanted roots; and although roots are extremely sensitive when moved, success can, as a rule, be insured by special care and prompt action, assuming that the proper time of year is chosen for the operation. The advantage of using roots is the saving of time, and in most gardens this is an important consideration. Fortunately roots may be planted almost as safely when two or three years old as at one year.
Soil.—Asparagus will grow in any soil that is well cultivated; a deep rich sandy loam being especially suitable. Calcareous soil is by no means unfavourable to Asparagus; still, a sand rich in humus is not the less to be desired, as the finest samples of European growth are the produce of the districts around Paris and Brussels. The London Asparagus, which is prized by many for its full flavour and tenderness, is for the most part grown near at hand, in deep alluvial soils enriched with abundance of manure. Nature gives us the key to every secret that concerns our happiness, and on the cultivation of Asparagus she is liberal in her teaching. The plant is found growing wild on the sandy coasts of the British Islands—a proof that it loves sand and salt.
