288 SELECTION OF PLANTS. 



under the head "Perennials" 1 in this work ; but if the 

 weather is inclined to he severe this work should be post- 

 poned till next month, though the autumn is preferable 

 as they usually blow stronger than when planted at this 

 season. 



Choice Carnations and Pinks ? in pots that are in 

 frames, should have as much air as possible, so that the 

 frosts do not injure them, otherwise they will be drawn up 

 weak. They must not be watered very often, or they will 

 be liable to rot. 



If not done in autumn, plant Box for edgings and 

 Thrift if required. 



THE GREENHOUSE. 



January. 



Give air to the plants when the weather is dry and open. 

 The plants should be kept warm by fires when the weather 

 is severe, and especially when it thaws, or is foggy, as 

 damps are frequently almost as injurious as the frosts. 



Leaves that are decayed should be always removed, as 

 they will infect others. 



Succulent plants, such as Aloes, Ficoides, &c. should 

 not be watered this month. Water should be given very 

 sparingly to any plants this month, and by no means use 

 spring water. It will be necessary that the water be in 

 the house sometime before using, otherwise the plants 

 will be chilled. 



In frosty weather keep all close, as one frost let into the 

 plants may be attended with considerable loss. 



The windows of the greenhouse should not be opened 

 before nine or ten in the morning, and all shut by four or 

 earlier, if it be likely to freeze.
