13. Planting in the garden. — In most parts of the North the 

 early plants are not transferred to the open ground before May 10 

 to 15. When set earlier than this, severe frosts may injure the 

 plants or cause them to produce seed shoots. Good plants set in 

 the field not later than May 15 should be large enough to sell by 

 August 1. Plants for the late crop are generally set in the field 

 the latter part of June and throughout the month of July. 



It is always important to manage the soil so that it will be well 

 supplied with moisture at the time of transplanting. Cloudy 

 weather and high humidity are also favorable to successful trans- 

 planting, because these conditions reduce the loss of water by 

 transpiration from the leaves, so that the plants do not wilt so 

 much as when there is warm, bright, clear weather. 



There is the widest variation in planting distances for celery. 

 When the early crop is to be blanched by the use of boards (W : 133) 

 the rows need not be more than eighteen inches apart, though 

 most growers prefer about two feet. This allows ample space for 

 cultivation or for mulching. (W:132.) If the crop is to be blanched
