"This exquisite vegetable resembles the cauliflower in growth, appearance, and flavour, and is supposed to have originated from it. Some of the varieties produce white heads, others purple, sulphur coloured, etc. It is cultivated with less trouble than the cauliflower, and heads with more certainty. The autumn is the season in which it is generally perfected, but with proper management may frequently be had throughout the winter and spring.
"The varieties are extensive, and differ in the time of ripening, as well as hardiness. Those we have cultivated with most success are the purple cape, sulphur coloured, and early cauliflower broccoli. There are also several other autumnal kinds, such as the green cape, early purple, early white, cream-coloured, or Portsmouth, etc.; but the purple cape is much the most certain to head, indeed the only one to be relied on in this climate. Our plan of cultivation has been, to sow the seed from the middle to latter end of spring; transplanting them when they attain the size at which cabbage plants are generally put out.
"Should the weather prove very dry at the periods in which it is proper to sow, some difficulty may be found in getting the seed to vegetate; in that case choose a spot shaded from the mid-day sun, and cover the bed with straw litter, lightly spread over the surface, which suffer to remain until the seeds sprout, when it should be immediately removed. Bass mats or cloths are sometimes used for this purpose; they should be removed every evening, and replaced in the morning, else the seed loses the benefit of the dew.
"A few observations only are necessary as to the progressive culture of the broccoli. Having, in the first place, selected a deeply dug, rich piece of ground, and planted them therein as you would cabbage plants, allowing them rather more room, do not neglect to hoe and stir the ground, keeping it perfectly clean and free from weeds; when they are six or eight inches high, land them up, that is, with the hoe draw around the base of the plants some of the loose soil, forming it like a basin, the stock of the plant being the centre. If dry weather ensue, give an occasional watering, which will greatly facilitate their growth.
"The earlier sowings will commence heading early in the autumn; the latter sown plants, many of them will show no appearance of heading before winter. On the approach of black frost they are to be removed to some sheltered situation, and "laid in," after the manner of winter cabbage; that is, burying the stalk entirely up to the lower leaves, the crown projecting at an angle of 45 degrees. They are more tender than the cabbage, and require to be protected against severe frost, which may readily be done by setting over them frames, such as are placed on hotbeds, and cover with shutters, or by setting boards on edge around them, the back the highest, on which lay a covering of boards similar to a roof. Thus they are sheltered from frost, and undue quantities of rain. As the winter advances, and the frost becomes more severe, give an additional covering, of straw scattered loosely immediately over the plants inside the board covering. In this situation they will remain secure, some of them heading from time to time during the winter, and most of them producing fine heads in spring.
Care should be observed to remove the straw covering on the arrival of spring, and to raise the shutters or boards in fine weather, that air may be freely admitted, removing them entirely the latter part of March.
"It is the practice of some who have light dry cellars, to place them therein, when removing them in the autumn, burying the roots and stalks as above directed. In that situation they require no further care or protection. Broccoli is sometimes sown about the middle of September, the plants pre-served in frames during winter, and put out in the spring. They are by no means certain to succeed well at that season; a few nevertheless might be thus managed, as they will generally head in the autumn, when failing to do so during the summer months.
"All the Brassica or Cabbage tribe is subject to be preyed upon by various insects, the most destructive of which in this country is the 'Black Fly' (Haltica nemorum); and in such immense quantities do they sometimes appear, and so voracious their appetite, that extreme difficulty is found in protecting the young plants from their depredations. As soon as they appear, take wood ashes, mixed with one-third air-slaked lime, and sprinkle over the entire plants, first wetting the leaves that the dust may adhere; this should be repeated as often as it flies off. or is washed off by rain. An application of lime water is also beneficial; it is disagreeable to the fly as well as the slug; the latter insect preys much upon them in damp weather. But the most certain preventive is a solution of whale-oil soap - a solution of common soft-soap or brown-soap, would probably answer the purpose; the alkali therein is particularly offensive to that troublesome intruder." - Rural Register.
