24 GREENHOUSE MANAGEMENT. 



feet, according to the size of the plants, and tying the 

 shoots to it. 



For the successful growing of hybrid roses in solid 

 beds, the houses should be so arranged that the glass 

 upon at least one side of the roof can be taken off. 

 This should be done by the first of July, to assist them 

 in ripening off, and if rain comes the roof should at once 

 be replaced. As soon as the plants are pruned the glass 

 should be replaced and a regular temperature maintained, 

 if the plants are to flower at Christmas. 



ROSES IN POTS AND BOXES. 



If only a few plants are usjd for forcing, they may 

 be grown in nine-inch pots, or in long boxes six inches 

 wide, and about the same depth. This method is par- 

 ticularly desirable for hybrid perpetuals. The small 

 plants should be grown the same as for the beds, and 

 should receive their final shift not later than the first of 

 July. The tea roses will do best if kept growing in the 

 house, although some florists think it well to harden 

 them by placing them out of doors when they are in 

 eight- or nine-inch pots and plunging them to their 

 rims in sand or coal ashes, the same as should be done 

 with the hybrids. They will need frequent syringing, 

 but care should be taken not to give enough water to 

 the soil to admit of their becoming water-soaked. By 

 the middle of August, the pots will be filled with roots, 

 and the teas should be removed to a cold frame, or a 

 cool house. 



The hybrids should be dried off, and will need the 

 same attention as those in solid benches, until the wood 

 becomes hard, when they should be pruned, and after 

 being first placed in a cold frame, should be gradually 

 brought in to heat. With the same care in watering, 

 syringing and ventilating as is given the roses in the 

 beds, they will bloom by Christmas. A house of hybrid 

 teas in bud is shown in Fig. 5.
