ONIONS.
Of this well-known garden vegetable there are quite a number of varieties.
1. The Large Red.—One of the most valuable.
2. The Yellow.—Large and profitable, keeping better than any other.
3. The Silver-skin.—The handsomest variety, excellent for pickling, brings the highest price of all, but is not quite so good a keeper as the red or yellow, and does not yield as well.
4. The White Portugal.—A larger white onion, often taken for the true silver-skin. It is a good variety. The preceding are all raised from the black seed, growing on the top.
5. The Egg Onion.—So called from its size and shape. On good rich soil, the average size may be that of a goose-egg, which it resembles in form. It is of a pale-red color, and more mild in flavor than any other. They are usually raised by sowing the black seed, very thick, to form sets for next year. Those sets, put out early, will form large onions for early market, that will sell more readily than any other offered.
6. The Top Onion.—So called because the seed consists of small onions, growing on the top of the stalks, in place of the black seed of other onions. These are good for early use, grow large, but are poor keepers.
7. The Hill or Potato Onion.—Of these there are several kinds, most of which are unworthy of cultivation. The Large English is the only valuable variety. The small onions, for sets, grow in the ground from the same roots, by the side of the main onion. Some of these grow large enough for cooking. The main onion is the earliest known, grows large, and has a mild, pleasant flavor;—they will mature at a certain season, whatever time you plant them; hence, they must be planted very early to produce a good crop. We have planted them on good ground so late as to get little more than the seed. They are fine for summer and fall use, but keep poorly. The foregoing are all that are necessary. They can all be brought forward by early planting of sets raised the previous season, by sowing the black seed so thick that they can not grow larger than peas, or small cherries.
Good sandy loam and black muck are the best soils for onions. Any good garden soil may be made to produce large crops; good, well rotted stable-manure and leached ashes are the best. The theory of shallow plowing, and treading down onion-beds is incorrect. The roots of onions are numerous and long. The land should be well-manured, double-plowed, and thoroughly pulverized. The only objection to a very mellow onion-bed is the difficulty of getting the seed up: this is obviated by rolling after sowing, which packs the mould around the seed, so as to retain moisture and insure vegetation. Fine manure, mixed in the surface of the soil for onions, is highly beneficial; on no other crop does manure on the surface do so much good. Mulching the whole bed, as soon as the plants are large enough, is in the highest degree beneficial, both in promoting growth, and keeping down weeds. An onion-bed must be made very smooth and level, to favor very early hoeing, without destroying the small plants. All root-crops that come up small, are tended with less than half the expense, if the surface be made very smooth and level. Never divide your onion-ground into small beds, but sow the longest way, in straight narrow rows, eighteen inches apart, for convenience of weeding and hoeing. Cultivate while very young, and work the soil toward the rows, so as to hill up the plants; this should be removed after they begin to form large bulbs. Breaking down the tops to induce them to bottom, is a fallacy: it will lessen the crop. Rich soil, deep plowing, thorough pulverizing, early sowing, and frequent hoeings, will insure success. Our system of double-plowing is the best for this crop. They will do equally well, some say improve, for twenty years on the same bed. Work the tops into the soil where the plants grow. Let the rows be very narrow and very straight, and you will save half the ordinary expense of cultivation.
To gather and preserve well, you should house them when very dry. A day's exposure to a warm autumn sun is very beneficial. Keep them in an open barn or shed until there is danger of frost. A warm, damp cellar always ruins them; keep them through winter in the coolest dry place possible, without severe freezing. Once freezing is not injurious, but frequent freezing and thawing ruins them. They are very finely preserved braided into strings and hung in a cool, dry room.
