VARIETIES OF CELERY 183 



packed in a car. Celery is shipped to all the principal cities of the 

 United States and Canada, and carries successfully. 



The Yield. An estimated yield per acre is about 1200 dozen 

 bunches, which may be worth $300 gross. The average cost of 

 growing the crop is placed at from $60 to $100 per acre. 



Varieties. Formerly the White Plume was the chief variety 

 grown for shipment, but it is now chiefly used where an early crop 

 is particularly desired. The Golden Self-blanching is now chiefly 

 grown, especially for eastern shipment and California seedsmen 

 offer improved strains Green Top. It will be well for home grow- 

 ers to try also some of the higher quality varieties offered by the 

 seedsmen when they are ready to take particular pains to grow them 

 well. Such varieties are Columbia, White Globe, Giant Pascal and 

 Winter Queen. These varieties are popular with market gardeners. 



Celery Blight. Occasionally atmospheric conditions favor the 

 growth of a leaf fungus known as celery blight, and great losses 

 have resulted in some years. Recent experience shows that the 

 blight is subject to control by spraying the plants with the Bordeaux 

 mixture, as described in Chapter XXXVIII, as soon as signs of the 

 incroachment of the disease appear, or when weather conditions in- 

 dicate the danger to be imminent. Special publications on this sub- 

 ject can be had from the University Experiment Station at Berkeley. 



CELERIAC. 



The turnip-rooted celery is very desirable for cooking and salad 

 purposes. It is grown in nearly the same way as ordinary celery 

 except that it is allowed to make free top growth without blanching, 

 as the root is the edible part. The Large or Giant Smooth Prague 

 is the variety chiefly grown.
