There is usually a good deal of loss in celery seed, so it is well to sow it very thickly, and then you may reasonably expect from 20,000 to 30,000 plants to the acre. An ounce of seed will plant about 200 feet of row, and if good, should give from 5000 to 10,000 plants, although where losses are very heavy the yield is frequently only 2000 to the ounce of seed. One pound of seed should give plants enough to set out four or five acres. Celery is grown both as an early-season and as a late crop, depending upon the location of the plot. On the higher lands, it is either an early or a succession-crop, following early cabbages, lettuce or other short-season crops. But on rich, bottom lands, it is a whole-season crop, as the land there is too wet to be worked early in the spring. Some growers raise two or three crops of celery in a season from one plot, the later or main crop being planted between the rows of the early crop. As celery may be set out as late as the middle or last of July, even in the Northern States, the main crop does not interfere with the early crop, which may be set out as soon as the ground is ready. For two crops, the soil needs more attention than where only one is raised, because cultivation and fertilizer must add and preserve the moisture which is natural to the lower levels. Celery needs potash and nitrogen, and these foods are supplied by unleached wood ashes and well-rotted stable manure. Coarse, new manures must not be used, as they make the soil coarse and also cause weeds. Only old, fine, well-rotted manure will do for the celery bed. When tillage is given the growing plant, care must be taken not to disturb the roots. The soil may be stirred only at the extreme end of the tiny rootlets, and if fertilizer is applied it must be placed at the same point. Some growers make tiny trenches between the rows and cultivate and fertilize there. Celery is one of the crops that call for thoroughly intelligent care. In many localities where the weather is hot or dry, sub-irrigation, by means of tile-drains, has supplied the needed moisture for this thirsty crop. There is an entirely new celery culture in the sterile sand of Florida by commercial fertilizer; but that is a subject by itself. The Florida Experiment Station will give particulars. The plants should be four or five inches high when transplanted and the stems stocky and green. They are set from 10 to 12 inches apart in the rows and the distance between the rows depends mainly upon the method of blanching. To bring a good price in the market, celery must always be blanched, although many growers prefer it in its natural condition for their own use.
