 At the close of the second 

 season the majority should 

 be large enough for sale. 



Lily bulbs are best dug 

 soon after their tops have 

 died. The shorter time they 

 remain out of the ground 

 and the cooler they are kept 

 the better. Small bulblets 

 should be allowed to remain 

 attached to the parent bulbs ; 

 but those, half an inch or 

 more across, may be sepa- 

 rated and grown in nursery 

 beds another season. 



112. Easter lilies from seed. 

 To avoid lily disease, G. W. 

 Oliver advocates growing 

 Easter lilies from seed rather 

 than from bulbs. He has 

 thus produced plants which 

 bloomed within seven months. 



113. Lily bulb disease is 

 caused by Rhisopus necans, 

 a parasitic fungus which ap- 

 parently cannot penetrate un- 

 broken tissues, but gains 

 entrance to the bulbs through 

 broken roots; for bulbs ex- 

 perimented with were not 

 diseased when dug. A brief 

 immersion in salicylic acid or 

 dilute corrosive sublimate 

 solution (1 to 100) will de- 

 stroy all spores on the bulbs. 

 Daffodils are subject to the 

 same disease. Precautionary 

 measures, such as rotation of 

 crops, avoidance of injury to 

 roots and destruction of ref- 

 use, are recommended. 

 When exported the bulbs 

 should first be dipped in the 

 fungicide and allowed to 

 sweat thoroughly before 

 shipment.
