Winter Managebient. 



All the stock plants intended to be preserved through the 

 winter, must be protected from frost in fined pits, or a cool 

 greenhouse. At the time of removal into winter quarters, 

 every dead leaf must be picked off, the pots washed clean, the 

 moss cleared off the surface, and a little fresh earth put on. 

 All straggling branches should be trimmed and tied up, and a 

 good syringing given to the shrubby species especially. As, 

 at the same time, most of the inmates of the greenhouse will 

 be taken in, it is desirable to fill the house with tobacco smoke, 

 two or three times, which will generally be found to destroy 

 all the green fly, or aphides on the plants, at this season. I 

 may here remark, that there is nothing so destructive to the 

 herbaceous species, as the green fly. I have known hundreds 

 of plants lost by their pernicious attacks; particular care must 

 therefore be taken, at all times of the year, against this pest. 

 In arranging these plants in the houses, the herbaceous spe- 

 cies should be placed nearest the glass, be sparingly watered, 

 and have abundance of air admitted on all favorable days. 

 The shrubby species will require rather more water, but the 

 treatment is the same, as to giving air. The cooler these 

 plants are kept during the dead season of winter, the better 

 specimens will they make for ornamenting the greenhouse, 

 when introduced into a growing heat, that is, providing they 

 do not get injured by frost. 



When fine specimens are desired, the plants may have a 

 shift into larger pots, in February. In performing this oper- 

 ation, a little of the top and side soil may be rubbed off with 

 the hand. The pots must be thoroughly drained, and a little 

 moss or rough soil put over the drainage; pot them moderate- 

 ly firm, and remove them into a pit or greenhouse, with a 

 temperature ranging from 50° to 55°, placing them close to 

 the glass ; they may then have sufficient water to wet the 

 soil through, and be kept as close to the glass as possible, for 

 a few days, which will encourage them to make fresh roots, 

 after which, air must be admitted at every favorable oppor- 

 tunity, being careful, however, to avoid cutting winds, which 

 are very injurious to the plants. Water when it is found ne-
