54 THE BOOK OF VEGETABLES 



Storage. In severe climates the plants may be taken 

 up with as much soil as possible, when hard freezing is 

 due, and set closely, but without crowding, in a pit, 

 frame, or cellar. Keep the roots moist. South of New 

 York City the plants may usually stand out-of-doors. 



Diseases and pests. See under Cabbage. The root 

 maggot is the worst. For aphis, use kerosene emulsion, 

 tobacco-water, pyrethrum, before the sprouts set. After- 

 wards^ hot water. 



BUCK'S-HORN PLANTAIN (Plantago Coronopus), 

 an annual salad-plant, grown for its young leaves. 

 Little known in America. 



Soil should be moist. 



Sow thinly in rows a foot apart, one-half inch deep, 

 in May. Thin to four inches. 



Culture. Give good culture, and water in a drought. 



Pick the young leaves as needed, for mixing in 

 salads. 



BURDOCK, EDIBLE, or GOBO (Lappa edulis). A 

 Japanese development of the common Burdock, grown 

 for its roots. Vilmorin-Andrieux commend it cautiously, 

 and urge an attempt to develop the Burdock as the 

 beet and carrot have been. 



Soil deep, well tilled, and not freshly manured. 



Distances. Rows eighteen inches to two feet apart ; 

 thin to nine inches in the rows.
