26 THE GRAPE CULTURTST. 



deep ; press the soil down firmly, but not so hard as to 

 break the roots. When the plants are potted, place them 

 again in the frames, give them water to settle the soil 

 about their roots, and keep the air somewhat confined for 

 a few days until they have become well established in the 

 soil, when a little more air may be given them. Keep the 

 temperature at 85 to 95 during the day and 70 to 80 

 at night. When the plants have made four to six inches 

 of stem, they may be taken out of the frames and placed 

 in another house which, if they are to remain under glass 

 during the season, should have been made ready for their 

 reception. 



Some propagators do not use frames within the house at 

 all, but depend entirely upon keeping the air moist and 

 hot as well as sufficiently confined by the ordinary methods 

 of heating and ventilating the house. While an experi- 

 enced propagator will usually succeed in this way, for 

 those who have not had experience in propagating, the 

 frames are much safer, and are enough better to pay the 

 extra cost even for the use of the most skillful. 



When the plants are first potted in the small pots they 

 will require so much more room than before, that it will 

 often be found inconvenient to furnish frames enough to 

 hold them ; in such cases they may be set upon shelves in 

 the open house, and they will do well in such a position if 

 care is given in keeping the atmosphere within the house 

 moist and warm, as well as in shading the plants and avoid- 

 ing direct currents of cold air from the outside through 

 doors or when ventilating the house. 



To get good, large, and strong plants, they will require 

 re-potting at least three times during the summer. At 

 each change the pots used should be increased in size 

 about two inches. The same compost may be used for 

 each re-potting, and the ball of earth around the roots 

 should not be broken, neither should the plants be placed 

 more than a half inch deeper than before. The proper
