from seed, enough sets should be planted to make an early supply for the table; if no sets are at hand in the fall, to plant for the spring crop of scallions, they could be grown by sowing the seed about a month earlier than you would plant the sets for the same purpose.
In sowing seeds for sets the same directions apply as given for the crop of bulbs, excepting that the seed is sown much more thickly, so that the bulbs will touch each other and stand two or three wide in the row. If they do not seem to be making the proper growth as the season advances, they should be thinned to the proper extent to enable them to grow to the right size, one-half inch in diameter, though my own trouble is that they usually grow too large; to remedy this when they are nearly the proper size I allow them to become choked with grass and weeds, which checks their growth, but when this is done they must be watched that this mass of stuff does not rot them off when ripe. I think a better way would be to go along the row with a straight-edged hoe or spade and cut off some of the roots. The main object in having the sets of this small size is that they shall not run to seed when planted out in the spring. Any sets which exceed three-quarters of an inch in diameter should be used for pickling or cooking. When the sets begin to ripen it will sometimes facilitate the process to bend all the green tops over close to the bulbs, as it helps to dry and shrivel the tops more quickly. When thoroughly ripe they should be gathered at once, the tops and roots pulled off, and should be spread out
