Dreer's Open-air vegetables (1897) Dreer's Open-air vegetables . dreersopenairveg00dree Year: 1897 CHAPTER XV. ONION The onion is botanically a lily. Its root is a bulb, made up of successive layers or scales. It is naturally hardy. The simplest way to grow onions is to buy the sets in the spring, and plant them just under the surface of the soil, as soon as the :IZETAKER OXIOX. , , , j ground can be worked. The next advance in onion cultivation is to raise them from seed, which is an operation usually requiring two years. The latest method is to produce full-sized onions the first year, direct from seed, by transplanting. The onion may be grown for several successive years on the same soil, if fertilized each year, as it shows less need of '' rotation '' than most of our garden crops. It delights in rich soil, cool weather and high culture. Hot, dry weather quickly checks its growth, causing it to ripen. The top dies, and for a time the bulb lies dormant; but if left in the soil it is liable to begin a new growth after a rainfall. Success in storing onions depends mainly upon ripening them thoroughly and then keeping them dry, with the least possible atmospheric change. They do best when spread in thin layers, in shaded and well ventilated places. They must never be handled when frozen ; and it is important not to bruise them when moving them from the field or afterward.
