THE GREEN-HOUSE.

Some of the bulbs and some pots of mignionette 

 should be placed at that end or part of the house 

 where the flue enters, in order to receive a little more 

 heat than the average temperature of the house. This 

 will probably bring the bulbs into blossom soon after 

 Christmas ; especially some of the Crocuses, Aconites, 

 blue Hyacinths, and Van Thol Tulips. In that 

 situation the mignionette will flower freely, and fill 

 the air of the house with its grateful odour. 



Sect. VI. Management of Green-house Plants 

 in Spring, 



About the middle of February many of the green- 

 house plants will be observed to be beginning to grow. 

 Insects also at this time make their appearance, and 

 some tender species that had stood the shock of win- 

 ter now die off in a manner not easily accounted for. 



Many plants also begin to show their blossom buds 

 at this season ; and as the days lengthen apace, and 

 more light is supplied by nature, more heat and water 

 may be added by man to encourage vegetation, and 

 render the villa green-house not merely a protection 

 for plants during winter like that of the nursery-man, 

 but a place for enjoying plants when they are not to 

 enjoyed in the open garden. 



To the usual routine operations of the green-house, 

 the spring season adds those of destroying insects, 

 and propagating plants by seeds or cuttings or other 

 means.
