secured the plants will form sufficient foliage to 

 exclude the light and blanch themselves. 



Planting in single rows 3 feet apart, with the 

 plants 4 inches apart in the rows, for blanching with 

 boards will undoubtedly give the best possible 

 yield, but requires 29,000 square feet of boards to 

 blanch an acre at one time. Twelve-inch boards 

 will blanch a double row, with the plants 6 inches 

 apart each way, and by planting the double rows 4 

 feet apart on centers, 21,000 square feet of lumber 

 is sufficient to blanch an acre at one time, and the

number of plants is the same in either case. 

 Blanching with earth requires that the spaces or 

 alleys between the rows shall be at least 4 or 5 feet, 

 and where the plants are set in double rows this 

 space should be at least 6 feet on centers. 



Where the land for growing celery is extremely 

 fertile and the area limited in size, the plan of 

 planting in solid beds may be resorted to, but is not
