FORCING OF ROSES. 181 



place all the young shoots from the top of the 

 stock above the graft should be shortened but 

 not taken off. 



In May, shoots from Tea- scented, China, 

 Bourbon, and Noisette Koses, grown in pots in 

 the greenhouse, will be fit to graft. In June, 

 shoots from roses of the same families, growing 

 against walls or in other warm situations in the 

 open air will be fit; in the last-named month, 

 artificial heat for the grafts may be dispensed 

 with, and a close frame, well shaded with mats in 

 sunny weather, and the plants sprinkled morning 

 and evening, will do very well, unless the weather 

 be windy and cool ; the grafts will then require 

 close moist heat, either from manure or hot water ; 

 in the former case, a common cucumber bed and 

 frame, kept closely shut, will answer every pur- 

 pose. These summer-grafted rose-trees are nicely 

 adapted for pot culture: those grafted in April 

 and May will bloom beautifully in the green- 

 house till the end of December. 



When the 4-inch pots in which the stocks 

 have been grafted become filled with roots, the 

 plants may be shifted into 7-inch pots, and 

 plunged in old tan or sawdust in a gentle hot- 

 bed, in a sunny exposed situation, till the end of 

 September, if the weather be warm and dry ; if 

 wet and cold, they should be removed to the 

 greenhouse early in the month : from the green- 

 house they may be repotted into 8 or 9-inch pots,
