BROCCOLI
Brassica oleracea botrytis asparagoides
The great importance of this crop is indicated by the long list of varieties and the still longer list of synonyms. As a vegetable it needs no praise, and our sole business will be to treat of the cultivation.
Of necessity we begin with generalities. Any good soil will grow Broccoli, but it is a strong-land plant, and a well-tilled clay should yield first-class crops. But there are so many kinds coming into use at various seasons, that the cultivation may be regarded as a somewhat complex subject. We will therefore premise that the best must be made of the soil at command, whatever it may be. The Cornish growers owe their success in great part to their climate, which carries their crops through the winter unhurt; but they grow Broccoli only on rich soil, and keep it in good heart by means of seaweed and other fertilisers. All the details of Broccoli culture require a liberal spirit and careful attention, and the value of a well-grown crop justifies first-class treatment. On the other hand, a badly-grown crop will not pay rent for the space it covers, to say nothing of the labour that has been devoted to it.
The Seed-bed.—Broccoli should always be sown on good seed-beds and be planted out; the seed-beds should be narrow, say three or three and a half feet wide, and the seed must be sown in drills half an inch deep at the utmost—less if possible; and where sparrows haunt the garden it will be well to cover the beds with netting, or protect the rows with wire pea guards. A quick way of protecting all round seeds against small birds is to put a little red lead in a saucer, then lightly sprinkle the seed with water and shake it about in the red lead. Not a bird or mouse will touch seed so treated.
The seed-beds must be tended with scrupulous care to keep down weeds and avert other dangers. It is of great importance to secure a robust plant, short, full of colour, and free from club at the root. Now, cleanliness is in itself a safeguard. It promotes a short sturdy growth, because where there are no weeds or other rubbish the young plant has ample light and air. Early thinning and planting is another important matter. If the land is not ready for planting, thin the seed-bed and prick out the seedlings. A good crop of Broccoli is worth any amount of trouble, although trouble ought to be an unknown word in the dictionary of a gardener.
Manuring Ground.—As a rule, Broccoli should be planted in fresh ground, and, in mild districts, if the soil is in some degree rank with green manure the crop will be none the worse for it. But rank manure is not needful; a deep, well-dug, sweet loam will produce a healthy growth and neat handsome heads. However, it is proper to remark, that if any rank manure is in the way, or if the ground is poor and wants it, the Broccoli will take to it kindly, and all the rankness will be gone long before they produce their creamy heads. Still, it must be clearly understood that the more generous the treatment, the more succulent will be the growth, and in cold climates a succulent condition may endanger the crop when hard weather sets in.
Method of Planting.—Broccoli follows well upon Peas, early Potatoes, early French Beans, and Strawberries that are dug in when gathered from for the last time. But it does not follow well upon Cabbage, Turnip, or Cauliflower; if Broccoli must follow any of these, dig deeply, manure heavily, and in planting, dust a little freshly slaked lime in the holes. The times of planting will depend on the state of the plants and the proper season of their heading in. But everywhere and always the plants should be got out of the seed-bed into their permanent quarters as soon as possible, for the longer they stay in the seed-bed the more likely are they to become drawn above and clubbed below. As regards distances, too, the soil, the variety, and the season must be considered. For all sorts the distances range from two to two and a half feet; and for most of the medium-sized sorts that have to stand out through the winter for use in spring, a distance of eighteen to twenty-four inches is usually enough, because if they are rather close they protect one another. But with strong sorts in strong soils and kind climates, two feet and a half every way is none too much even for safe wintering. Plant firmly, water if needful, and do not stint it; but, if possible, plant in showery weather, and give no water at all. Watering may save the crop, but the finest pieces of Broccoli are those that are secured without any watering whatever.
Autumn Broccoli.—To grow Autumn Broccoli profitably, sow in February, March, and April, the early sowings in a frame to insure vigorous growth, and the later sowings in the open ground. Plant out as soon as possible in fresh land that has been deeply tilled. If the soil is poor, draw deep drills, fill them with fat manure, and plant by hand, taking care to press round each root crumbs from the surface soil. This will give them a good start, and they will take care of themselves afterwards. When they show signs of heading in, run in shallow drills of Prickly Spinach between them, and as this comes up the Broccoli will be drawn, leaving the Spinach a fair chance of making a good stolen crop, needing no special preparation whatever. Another sowing of Broccoli may be made in May, but the early sowings, if a little nursed in the first instance, will pay best, because early heads are scarce, whereas late Broccoli are plentiful.
Winter Broccoli should not be sown before the end of March and thence to the end of April. As a rule, the April sowing will make the best crop, although much depends on season, soil, and climate. Begin to plant out early, and continue planting until a sufficient breadth of ground is covered. Within reasonable limits it will be found that the time of planting does not much affect the date when the heads turn in, and only in a moderate degree influences the size of them.
