Chapter 12

Treatment of Soil.—The soil for Peas must be rich, deep, and friable, and should contain a notable proportion of calcareous matter. Old gardens need to be refreshed with a dressing of lime occasionally, or of lime rubbish from destroyed buildings, to compensate for the consumption of calcareous matters by the various crops. For early Peas, a warm dry sandy soil is to be preferred; for late sorts, and especially for robust and productive varieties, a strong loam or a well-tilled clay answers admirably, and it is wise to select plots that were in the previous year occupied with Celery and other crops for which the land was freely manured and much knocked about. Heavy manuring is not needed for the earliest Peas, unless the soil is very poor, but for the late supplies it will always pay to trench the ground, and put a thick layer of rotten manure at the depth of the first spit, in which the roots can find abundant nutriment about the time when the pods are swelling. In all cases it is advisable not to enrich in any special manner the top crust for Peas. When the young plant finds the necessary supplies near at hand, the roots do not run freely but are actually in danger of being poisoned; but when the plant is fairly formed, and has entered upon the fruiting stage, the roots may ramify in rich soil to advantage. Hence the desirability of growing Peas in ground that was heavily manured and frequently stirred in the previous year, and of putting a coat of rotten manure between the two spits in trenching. As regards the last-named operation, it should be remarked that as Peas require a somewhat fine tilth, the top spit should be kept on the top where the second spit will prove lumpy, pasty, or otherwise unkind. In this case bastard trenching will be sufficient; but when the second spit may be brought up with safety, it should be done for the sake of a fresh soil and a deep friable bed. The use of wood ashes, well raked in immediately in advance of sowing, will prove highly beneficial to the crop, for the Pea is a potash-loving plant.

Method of Sowing.—It will always pay to sow in flat drills about six inches wide, but the V-shaped drill in which the seedlings are generally crowded injuriously is not satisfactory. Two inches apart each way is a useful distance for the seed, although more space may be given for the robust-growing maincrop and late varieties. It is wise policy, however, to sow liberally in case of losses through climatic conditions, birds or mice; and if necessary superfluous plants can always be withdrawn. The depth for the seed may vary from two to three inches: the minimum for heavy ground and the maximum for light land.

Early Crops (sown outdoors).—Early Peas are produced in many ways. The simplest consists in sowing one or more of the quick-growing round-seeded varieties in November, December, and January, on sloping sheltered borders expressly prepared for the purpose, and provided with reed hurdles to screen the plants from cutting winds. Where the assaults of mice are to be apprehended, it is an excellent plan to soak the seed in paraffin oil for twenty minutes, and then, having sown in drills only one inch deep, heap over the drill three inches of fine sand. If this cannot be done, sow in drills fully two inches deep, for shallow sowing will not promote earliness, but it is likely to promote weakness of the plant. It is not usual to grow any other crop with first-early Peas, but the rows must be far enough apart to prevent them from shading one another, and, if possible, let them run north and south, that they may have an equable enjoyment of sunshine. As soon as the plant is fairly out of the ground, dust carefully with soot, not enough to choke the tender leaves, but just sufficient to render them unpalatable to vermin. When they have made a growth of about three inches, put short brushwood to support and shelter them, deferring the taller sticks until they are required. Then fork the ground between, taking care not to go too near to the plant. Sticks must be provided in good time, lest the plant should be distressed, for not only do the sticks give needful support, but they afford much shelter, as is the case with the small brushwood supplied in the first instance.

On fairly warm soils the first opportunity should be taken to sow one of the early dwarf marrowfat varieties in the open ground. This may be in February or early March, but it will be useless to make the attempt until the ground is in a suitable condition. Sow in flat drills as already described, the distance from row to row depending upon future plans. If no intercropping is to be done, eighteen inches between the rows will generally suffice for dwarf-growing Peas, but many gardeners prefer to allow three feet and to take a crop of Spinach on the intervening space.

Early Crops (sown under glass.)—We now come to the modes of growing early Peas by the aid of glass. The surest and simplest method is to provide a sufficiency of grass turf cut from a short clean pasture or common. There is in this case a risk of wireworm and black bot; but if the turf is provided in good time and is laid up in the yard ready for use, it will be searched by the small birds and pretty well cleansed of the insect larvas that may have lurked in it when first removed. Lay the turves out in a frame, grass side downwards, and give them a soaking with water in which a very small quantity of salt has been dissolved. This will cause the remaining bots and slugs to wriggle out, and by means of a little patient labour they can be gathered and destroyed. In January or February sow the seed rather thickly in lines along the centre of each strip of turf, and cover with fine earth. By keeping the frame closed a more regular sprouting of the seed will be insured; but as soon as the plants rise, air must be given, and this part of the business needs to be regulated in accordance with the weather. All now depends on the cultivator, for, having a very large command of conditions, it may be said that he is removed somewhat from the sport of the elements, which wrecks many of our endeavours. There are now three points to be kept in mind. In the first place, a short stout slow-growing plant is wanted, for a tall lean fast-growing plant will at the end of the story refuse to furnish the dish of Peas aimed at. Give air and water judiciously, and protect from vermin and all other enemies. A little dry lime or soot may be dusted over the plants occasionally, but not sufficient to choke the leaves. All going well, plant out in the month of March or April, on ground prepared for the purpose, and laying the plant-bearing turves in strips, without any disturbance whatever of the roots. Then earth them up with fine stuff from between the rows, and put sticks to support and shelter them.

A more troublesome, but often a safer method, is to raise plants in pots, or in boxes about four and a half inches deep and pierced at the bottom to insure free drainage. Old potting soil will answer admirably, and the seeds should be put in one inch deep and two inches apart. Place the pots or boxes in any light cool structure as near the roof-glass as possible, but make no attempt to force either germination or the growth of the plants. When fair weather permits, transfer to the open in March or April. A good succession may be obtained by sowing a first-early dwarf variety and a second-early kind simultaneously.

Main crops require plenty of room, and that is really the chief point in growing them. Supposing the ground has been well prepared as already advised, the next matter of importance is the distance between the rows. The market gardener is usually under some kind of compulsion to sow Peas in solid pieces, just far enough apart for fair growth, and to leave them to sprawl instead of being staked, because of the cost of the proceeding. But the garden that supplies a household is not subject to the severe conditions of competition, and Peas may be said to go to the dinner table at retail and not at wholesale price. Moreover, high quality is of importance, and here the domestic as distinguished from the commercial gardener has an immense advantage, for well-grown ‘Garden Peas’ surpass in beauty and flavour the best market samples procurable. To produce these fine Peas there must be plenty of space allowed between the rows, and it will be found good practice to grow Peas and early Potatoes on the same plot, and to put short sticks to the Peas as soon as they are forward enough. By this management the first top-growth of the Potatoes may be saved from late May frosts, and the Peas will give double the crop of a crowded plantation. The general sowings of Peas are made from March to June, but as regards the precise time, seasons and climates must be considered. Nothing is gained by sowing maincrop Peas so early as to subject the plant to a conflict with frost. It should be understood that the finest sorts of Peas are somewhat tender in constitution, and the wrinkled sorts are more tender than the round. Hence, in any case, the wrinkled seeds should be sown rather more thickly than the round to allow for losses; but robust-habited Peas should never be sown so thickly as the early sorts, for every plant needs room to branch and spread, and gather sunshine by means of its leaves for the ultimate production of superb Green Peas.

Late Crops.—To obtain Peas late in the season sowings may be made in June and July, and preference should be given to quick-growing early varieties. Ground from which early crops of Cauliflower, Carrot, Cabbage, Potatoes, &c., have been removed is excellent for the purpose. In dry weather thoroughly saturate the trench with water before sowing, and keep the seedlings as cool as possible by screening them from the sun.

Staking.—This important operation must not be unduly deferred, as the plants are never wholly satisfactory when once the stems have become bent. Commence by carefully earthing up the rows as soon as the plants are about three inches high. In the case of early varieties, light bushy sticks of the required height, thinly placed on both sides of the row, will suffice. Maincrop and late Peas, however, should first be staked with bushy twigs about eighteen inches high, these to be supplemented with sticks at least one foot taller than the variety apparently needs, as most Peas exceed their recognised height in the event of a wet season. No attempt should be made to construct an impenetrable fence, for Peas need abundance of light and air. Neither should the stakes be arched at the top, but placed leaning outwards.

General Cultivation.—On the first appearance of the plant, a slight dusting of lime or soot will render the rising buds distasteful to slugs and sparrows, but this is more needful for the early than the later crops. When maincrop Peas have grown two or three inches, they are pretty safe against the small marauders. As the plant develops, frequently stir the ground between the rows to keep down weeds and check evaporation. The earthing up of the rows affords valuable protection to the roots of the plants, and a light mulch of thoroughly decayed manure will prove very helpful in a dry season. In the event of prolonged dry weather, however, measures must be taken to supply water in good time and in liberal quantity. The advantage of deep digging and manuring between the two spits will now be discovered, for Peas thus circumstanced will pass through the trial, even if not aided by water, although much better with it; whereas similar sorts, in poor shallow ground, will soon become hopelessly mildewed, and not even water will save them. In giving water, it will be well to open a shallow trench, distant about a foot from the rows on the shady side, and in this pour the water so as to fill the trench; by this method water and labour will be economised, and the plant will have the full benefit of the operation.

The enemies Of Peas are fewer in number than might be expected in the case of so nutritive a plant. Against the weevil, the moth, and the fly, we are comparatively powerless, and perhaps the safest course is occasionally to dust the plants with lime or soot, in which case the work must be carefully done, or the leaf growth will be checked, to the injury of the crop. Light dustings will suffice to render the plant unpalatable without interfering with its health, but a heavy careless hand will do more harm than all the insects by loading the leafage with obnoxious matter. The great enemy of the Pea crop is the sparrow, whose depredations begin with the appearance of the plant, and are renewed from the moment when the pods contain something worth having. Other small birds haunt the ground, but the sparrow is the leader of the gang. Ordinary frighteners used in the ordinary way are of little use; the best are lines, to which at intervals white feathers, or strips of white paper, or pieces of bright tin are attached. In the seedling stage the plants may be protected by wire guards, and even strands of black thread tied to short stakes will prove serviceable. We have found the surest way to guard the crop against feathered plunderers is to have work in hand on the plot, so as to keep up a constant bustle, and this shows the wisdom of putting the rows at such a distance as will allow the formation of Celery trenches between them. We want a crop to come off, and another to be put on while the Peas are in bearing; and early Potatoes, to be followed by Celery, may be suggested as a rotation suitable in many instances. Even then the birds will have a good time of it in the morning, unless the workmen are on the ground early. However, on this delicate point, the ‘early bird’ that carries a spade will have an advantage, because the sparrow is really a late riser, and does not begin business until other birds have had breakfast, and have finished at least one musical performance.

Early Peas under Glass.—So greatly esteemed are Peas at table that in many establishments the demand for them is not limited to supplies obtainable from the open ground. Sowings may be made from mid-November to mid-February, according to requirements and the extent of accommodation available, from which the crops may be expected to mature from mid-March onwards. Where a large glass-house, such as is used for Tomatoes, &c., is at command, early Peas may be grown without prejudice to other crops. Assuming that a good depth of soil exists, thoroughly trench and prepare it as for outdoor Peas. Select a tall-growing variety, of which there are a number that do well under glass. Sow in a triple row, placing the seeds about three inches apart each way, and in due course support the plants with stakes. A cool greenhouse or a frame will also carry through an early crop of Peas, but for these structures pots should be used and only dwarf-growing varieties sown. A ten-inch pot will accommodate about eight seeds, and these should be planted one and a half inches deep. When a few inches high insert a few bushy stakes to carry the plants. A compost consisting of two parts loam, one part leaf-soil or well-decayed manure, with a small quantity of wood ashes, will suit Peas admirably. At no time is a forcing temperature needed. From 50° to 55° at night, with a rise of about 10° by day will suffice, and free ventilation must be given whenever possible with safety. Apply water carefully, but never allow the roots to become dust-dry.

Peas for Exhibition.—On the exhibition table handsome well-grown Peas always elicit unstinted admiration, and the magnificent pods of the newer varieties are certainly worthy of the utmost praise bestowed upon them. In all cases where vegetables are grown for competition at Shows the amount of success achieved depends largely on the intensity of the cultivation adopted, and in this respect no other subject will respond more readily to liberal treatment than will the Garden Pea. Deep digging, generous manuring, and copious watering during dry weather, in the manner already described, are fundamental essentials. Another matter of no less importance is the selection of suitable varieties. It is now the general custom to start the early sorts in pots or boxes under glass (see page 104), and some growers treat mid-season Peas in the same manner. Of this system it may be said that it offers the fullest opportunity of giving attention to the young plants and allows of the strongest specimens being selected for transfer to open quarters. The number of sowings will, of course, depend on individual requirements. At the time of transplanting give each plant plenty of space for development, and it will be well to stake the rows immediately. Keep the plants under constant observation, especially while quite young, when they are liable to destruction by garden foes. The flowering should be limited to the fourth spike, and from the time the pods appear assistance must be given in the form of liquid manure or a mulching of well-rotted dung. Remove all lateral shoots and promote vigorous healthy growth at every stage. Some means should be adopted to prevent injury of any kind to the pods, which when gathered should be well filled, carrying a fine bloom free from blemish.

POTATO

Solarium tuberosum

The potato has been designated the ‘King of the Kitchen Garden,’ and perhaps ‘the noble tuber’ should be so regarded. Of its importance as an article of food it is impossible to speak too highly, and the dietetic value of the Potato appears to be always advancing. The known deficiency of flesh-forming constituents naturally associates this vegetable with meat of various kinds, poultry, game and fish, and in this proper association the root is probably capable of superseding all other vegetable foods, bread alone excepted. It is far from our intention to recommend abstention from Asparagus, Cauliflower, Peas, and Sea Kale, and to regard Potatoes as a sufficient substitute for these and other table delicacies; but it is well to remember that by virtue of its starchy compounds the Potato has a direct tendency to promote health and that freshness of complexion that generally prevails among well-fed people.

Forcing Potatoes.—The demand for new Potatoes exists long before the first of the outdoor crops grown in this country can be lifted. To meet such a demand is not a difficult matter where the necessary amount of glass is at command, and by adopting the method here given supplies may be maintained through the winter and onwards until the first-earlies from the open ground are available. It may be said at once that for culture in pots and boxes under glass a high temperature is neither requisite nor desirable. Sturdy healthy growth is essential to the formation of a crop of tubers, and if the plants be forced into an attenuated condition the labour will have been in vain. Another matter which needs to be specially mentioned is the choice of suitable varieties. Only dwarf-growing kinds, thoroughly adapted for forcing, should be considered. The date of planting will necessarily be regulated by the time at which the crop is required. But a few weeks in advance of planting, the sets should be sprouted by placing them on end in shallow boxes, packed with damp light soil and stood near the light in a slightly warm pit or house. When the sprouts are formed rub off all but the two strongest. Good turfy loam, a small quantity of manure from a spent Mushroom bed, and a little bone meal, will make an excellent compost for the pots or boxes. Two sets will suffice for a ten-inch or twelve-inch pot, or five tubers may be placed in a box measuring about four feet long by one foot wide. Perfect drainage must be insured. Plant the sets with care, taking up as much soil as possible with the mass of fibrous roots which will have formed during the period of sprouting. The operation may best be accomplished by only half filling the pots or boxes at first, and when the sets are in position add a further two inches or so of soil. Water sparingly, especially at the outset. As root growth increases add more soil and give the plants an occasional application of tepid liquid manure. At all times avoid excessive heat, and if the crop can be finished off gradually in a cool house so much the better.

Where sufficient accommodation cannot be found for forcing Potatoes in pots or boxes, an excellent crop may be grown on a gentle hot-bed made up in the usual manner, and covered to a depth of at least nine inches with a compost of three parts light loamy soil to one part leaf-mould. After putting on the frame, keep the lights closed for a few days. But a great heat is not wanted, and undue forcing at any stage will lead to disaster. Partially exhausted hot-beds which have been used for other purposes will also be found to answer admirably. Prepare the sets in the manner already advised for pots and boxes, and plant them with the least possible disturbance to the fibrous roots, three inches deep, in rows fifteen inches apart, allowing twelve inches between the tubers in the row. Whenever the weather is fine afford the plants a little air. Increase the amount gradually as growth develops, but close the frames early in the afternoon and give them the protection of mats at night should the outside temperature be low. Water must be given in moderation. It should always be of the same temperature as the frame, and as soon as the haulm commences to turn yellow watering must be discontinued. Little earthing up is needed, but when the foliage is about nine inches high the addition of a small quantity of warm soil along the rows will be beneficial.

Early Potatoes outdoors are produced in various ways, and by very simple appliances. The Potato will not bear the slightest touch of frost. It is a sub-tropical plant, and will endure considerable heat if at the same time it can enjoy light, air, and sufficient moisture. In some respects it may be likened to the Lettuce, for if crowded or overheated, or subjected to sudden checks, it bolts—in other words, it produces plenty of top and no bottom, just as Lettuces similarly treated produce flowering stems and no hearts. We will here propose a very simple and practical procedure for obtaining a nice crop of Potatoes in the month of June. This system fairly mastered, endless modifications will be easily effected as circumstances and judgment may suggest.
