The radishes came up quick, filling the garden canopy completely that fall, and the following spring we found the plot was clean of weeds and rows of open holes were left where the radish roots had been growing. Well, we had a few extra onion plants that spring and decided to plant them in these holes, since we already had very clear lines laid out for us and a clean seedbed. What we got were the best looking onions that have ever come out of our gardens.
The onion is one of the important market-garden and truck crops in the United States and is very generally grown in home gardens. It thrives best on alluvial and drained muck soils under a temperate climate, but may be grown under a very wide range of soil and climate conditions. Onions are grown to perfection on the alluvial soils of the Nile River Valley in Egypt, under the sea breezes of the South Sea Islands, on the delta lands along the sea coast, on sandy uplands, in the arid regions under irrigation, and on reclaimed swamp lands. There is perhaps no extensive area in the United States or its possessions where the onion, in one or more of its forms cannot be successfully grown, at least for home and local use.
