GENERAL RULES OF CULTURE. 



During growth, copious syringing should be given, to 

 destroy the red spider, the great enemy of greenhouse bulbs.

They should not be allowed to ripen seed. After bloom- 

 ing, the leaves ■ should be grown until the tips begin to 

 turn yellow ; when water should be less freely administered, 

 and the plants be gradually dried off. When thus at rest, 

 the pots should be turned on their sides, placed on shelves 

 under the greenhouse stage, or in a shed or cellar, and so 

 remain until the season for repotting. Bulbs with ever- 

 green foliage should never be entirely dried of; but the 

 supply of water should be greatly reduced until the plants 

 again show signs of growth.
