FLOWER DEPARTMENT. 



Dahlias. — When there is a great number of plants to set out, ope- 

 rations maj' be commenced the latter part of the month; but if only a 

 few are to be transplanted, it is best to put them into the border a- 

 bout the first of June, and from that time to the 15th. Those ])lant- 

 ed late produce the best flowers in September. 



Jioses, of the monthly and other tender sorts, may now be turned 

 out of the pots into the border. 



Camellias will need attention; water freely, and syringe over the 

 foliage at least three times a week.

Pansies may be transplanted in the border, and seeds may be sown 

 now for a succession of plants. 



Verbenas may now be turned out into the border. 



Geraniums will now be flowering: give plenty of water and air. 



Ericas may be propagated by cuttings now.

 this month.

 its appearance, the plants should be syringed with whale oil soap, 

 every three or four days. 



Perennial flower seeds may be planted the latter part of this 

 month.
