CULTURE UNDER GLASS 75 



sweet peas. In the warmer states sweet 

 peas are grown out of doors during the 

 winter, requiring but very little shelter. 



For sweet peas under glass it is neces- 

 sary to have a suitable house (see Frontis.) . 

 The sides of the house should be at least 

 eight feet high, the upper being of glass. 

 If the houses are but seven feet high, the 

 side rows strike the glass when the vines 

 are about half grown, thereby giving half 

 a crop. The ridge of the house should be 

 from twelve to fifteen feet high. The 

 higher the vines grow, the more and bet- 

 ter flowers. For December and January 

 cuttings, large houses are necessary so that 

 the sun may penetrate every corner. 

 Sweet peas sown in October as, for exam- 

 ple, after chrysanthemums, will not bloom 

 before February, 



The ideal soil is sandy loam. Red shell 

 soil is good if taken about six inches below
