dressing of dry litter placed over the roots and round 

 the stem. The heads should be gathered just before 

 the central scales begin to unfold and while the outer 

 ones are still plump and fresh. In the autumn a good 

 dressing of manure should be laid on the surface of the 

 ground between the two rows. 



Celery 



Celery should be sown in March in gentle heat, and as 

 soon as large enough to handle the young plants should 

 be pricked out in boxes or small pots. When about 

 two inches high they should again be transplanted, 

 being kept in a cool glass-house or other fairly warm 

 place until May or June. They should then be planted 

 out in trenches as advised for Leeks, and in August 

 should be earthed up in the same manner. The final 

 earthing up should take place about the end of September, 

 and about a month later the crop will be ready for 

 gathering. If it is wished to keep the Celery through 

 the winter it must be covered with litter or dry leaves 

 during frost. It is impossible to give too much water 

 during the summer months. 



Good varieties are Sandringham and Major Clarkes. 



Celeriac 



Celeriac or turnip-rooted Celery is much easier to grow 

 than Celery, and is one of the most useful of winter 

 vegetables. It is valuable for soups and as a boiled 

 vegetable, having a flavour intermediate between that of 

 Celery and Salsify. The seed may be sown in March 

 in heat and the seedlings subsequently transplanted, 

 though the easiest method is to prepare trenches about 

 six or eight inches deep, half fill them with well-rotten 

 manure, thoroughly mix this with soil, lay on it a layer
