116 MARKET GARDENING. 



or runners V-shaped, three feet long, twelve inches deep, 

 and four or five inches wide at the rear end. The driver 

 rides, and the rows, when opened, are about two inches 

 deep and four inches wide. 



Before a crop of celery can be expected to grow lux- 

 uriantly, the land must be prepared thoroughly. This 

 previous cultivation for celery must include deep cul- 

 ture. Celery roots demand plenty of room. The writer 

 has walked over a celery field after potatoes, where plants 

 had been set out four weeks, and, by digging down 

 twelve inches, found celery roots filling all the soil. 

 Get the cultivation deep ; carry the manure along and 

 keep weeds out of sight, and, where possible, irrigate 

 during dry seasons. 



Transplanting may be done in the latter part of 

 June for early crops, but celery grown in market gardens 

 as a second crop is not usually put in until the ground is 

 entirely cleared of the preceding crops. The cabbages and 

 other vegetables being disposed of early in July, the 

 celery planting can then begin. It is not desirable to 

 forward celery for marketing in the early autumn, be- 

 cause there is not much demand for it until poultry 

 appears in market. About the 15th of July to middle 

 of August is usually, in the latitude of Philadelphia, the 

 season for transplanting out in the field ; but the first 

 weeks of July give best results, the plants having the 

 help of July rains in their new position, while later set- 

 ting must sometimes be followed by irrigation. 



The transplanting may be all done at once, or in 

 two or three successive crops. In midsummer there is, 

 as a rule, but little rain, while wet weather is desirable, 

 for the planting can be not only better done in rainy 

 weather, but the plants need the excess of moisture to 

 enable them to take root during a season of heat. Every 

 arrangement should, therefore, be made beforehand, so 

 that a seasonable rain may be taken advantage of. In
