If young green onions with thin, succulent tops are desired very early in spring, it will be an interesting experiment to sow the seed the latter part of August or early in September. Another method is to leave a row of onions in the garden where they ripened. When the autumn rains begin, they will start to grow again. The winter will not harm them, and even in April there will be a strong growth of green tops. The seed stalk should be picked off as soon as it appears in spring, or else the whole strength will speedily go to the formation of seed.
It should be remembered that good onions can not be produced very far to the south by sowing the small gunpowder-like seed. In our own and especially in warmer climates a great advantage is secured by employing what are known as “onion sets.” These are produced by sowing the ordinary black seed very thickly on light poor land. Being much crowded, and not having much nutriment, the seed develop into little onions from the size of a pea to that of a walnut, the smaller the better, if they are solid and plump. These, pressed or sunk, about three inches apart, into rich garden soil about an inch deep, just as soon as the frost is out, make fine bulbs by the middle of June. For instance, we had in our garden plenty of onions three inches in diameter from these little sets, while the seed, sown at the same time, will not yield good bulbs before August. There is but little need of raising these sets, for it is rather difficult to keep them in good condition over the winter. Any seedsman will furnish them, and they are usually on sale at country stores. Three or four quarts, if in good condition, will supply a family abundantly, and leave many to be used dry during the autumn. Insist on plump little bulbs. If you plant them early, as you should, you will be more apt to get good sets. Many neglect the planting till the sets are half dried up, or so badly sprouted as to be wellnigh worthless. They usually come in the form of white and yellow sets, and I plant an equal number of each.
