Lilies (Lilium longiflorum) 



Cultural Considerations. The secret of success 

 with lilies is in strong and vigorous bulbs. Lilies 

 forced for the Christmas market should be planted 

 in a rich soil thoroughly mixed with well rotted 

 stable manure. After having been potted, the bulbs 

 should be placed in a cold frame or in a cool dark 

 cellar to encourage the rapid rooting. After that 

 they are maintained at a temperature of 50, then 

 60, then 75 degrees F. in the house. Lilies for the 

 Easter trade are bought about the middle of Decem- 

 ber. Lilium speciosum var. rubrum is especially 

 well adapted for forcing. 



Diseases of Lilies 



Lilies are subject to quite a number of diseases all 

 of which are of economic importance.
