THE PRODUCTION OF CELERY SEED 133 



sowing in a spent hotbed or in a cold-frame, allow- 

 ing the plants to remain in the bed, with sufficient 

 protection to prevent the roots becoming frozen, 

 until the following spring. During the early spring 

 the plants should be lifted and the most perfect ones 

 planted in rows where they may be cultivated dur- 

 ing the first part of the season, or until they shoot 

 to seed. The flower stems are from 2 to 3 feet in 

 height and the flowers and seeds are borne in um- 

 bels or clusters. As the seeds become ripened they 

 should be gathered and spread on cloth screens in 

 a shaded place until dry. The seeds should then be 

 stored in a dry place until wanted for planting dur- 

 ing the following winter or spring.
