FORCING FLOWERS AND PLANTS. 173 



in the cold frame till October, be removed to the gieenhouse 

 temperature tiU !N'ovember, and then removed to the forcing- 

 house, being at a temperature of forty-five by night, or even 

 fifty; and fifty-five to sixty, or, with sun, sixty-five in the 

 day, — beyond this it ought not to be allowed to get. "When 

 the roses put forth their branches, remove all but those 

 growing in a good direction for the head of the following 

 year; and as soon as the buds are seen anywhere, let them 

 be taken off, as they only retard the growth of the wood. 

 Continue them in the house to make all their growth, and 

 keep taking off their buds. The wood will perfect itself in 

 the course of the winter ; and when the warm spring months 

 come, they may be taken away, be re-potted in larger-sized pots 

 and plunged into the ground, with a proper support to keep 

 them from injury by winds. These plants will have ripened 

 their wood much earlier than the roses bloomed out of doors, 

 and will, therefore, be so much the sooner ready to start again. 

 When, therefore, they are put into the greenhouse in the 

 early part of September, they will be half inclined to start 

 without heat ; because they will have had their full period of 

 rest, and will naturally want to grow. Thus the growth 

 which required a good deal of forcing, and a long period of 

 heat the previous year, will be almost spontaneous the second, 

 and a much less heat will do, or if the same heat, not of so 

 long continuance. We have, however, besides the advantage 

 of easier forcing, better forcing ; the plants will not want so 

 much heat nor want it so long, so that the growth will be 

 stronger. 



Before, however, we place the roses in the greenhouse, we 

 have to prune them, as we would out-of-door roses in the 

 early spring ; regard must be had to the shape of the head, 

 the number of branches we require, and where we want 

 them. Cutting back to one, two, or, three eyes, according to 

 the number of branches we want, must be attended to at 

 once, before they are allowed to shoot at all ; because the 

 vigour of the plant would be wasted in the buds we intended 

 to remove. This second year, therefore, the roses will be a 

 better form, as well as stronger in their growth. As soon as 

 the roses indicate the presence of the aphis, let the house be 

 closed and fumigated with tobacco ; there is nothing else that 

 will effectually remove or destroy them. And when the buds 

 are bursting, the plants may be removed to the conservatory,
