small and short that the plants are essentially surface 

 feeders. 



If radishes are to be grown in hot weather, the land 

 should be as cool as possible and supplied 

 with abundance of moisture to keep them 

 growing continuously. It is well to grow 

 the regular summer radishes, as Stras- 

 burg, but as there may not be a market 

 for them, the small spring radishes may 

 have to be carried into the summer. 



For the market, 

 radishes are washed 

 and tied in 

 bunches of 4 to 10, 

 with the tops left 

 on. They should 

 be kept moist until 

 sold. If the tubers 

 are graded to size, 

 shape and color 

 they make very at- 

 tractive produce. 

 The radish is annual and biennial. Eoots maturing 

 late may be kept over winter and planted in the spring, 

 when they quickly run to seed. Spring and summer rad- 

 ishes run to seed the same season if left in the ground, but 

 the best seed is produced from plants that are transplanted 

 when young. Little radish seed is grown in North 

 America, probably largely because of the high price of 

 labor. 



Probably the most popular variety is French Breakfast,
