IOO CARE OF PLANTS. 



them than in a frame. Moreover they will grow 

 better because the air can be kept more moist, 

 diseases and insects can be kept down, and all con- 

 ditions necessary for growth can be managed to 

 better advantage. 



We mention the ordinary cold frame with 

 sash not because we favor it, but merely to show 

 that they have been given fair trial and have been 

 found wanting. This method of propagation ap- 

 plies particularly to the Campbell violet. If all the 

 conditions are carefully watched, fine plants can 

 be grown in this way. We do not advise 

 using boxes or flats with close bot- 

 toms as drainage is not so good and 

 the roots in consequence will not 

 develop so well. Roots need air at all 

 times, and where this is given through proper 

 soil, proper drainage, and proper watering, it is 

 astonishing the way the young plants start off and 

 grow. 



The third method of propagation and the one 

 generally followed by growers of Marie Louise, 

 consists in taking cuttings from the crowns any 

 time between the middle of January and the mid- 

 dle of March. These cuttings in many cases have 

 already made some air roots, but these should all 

 be trimmed off at the same time the cutting proper 

 is trimmed up. After trimming, the cuttings are 

 put in sand to root. The sand is an important 

 item. It should be moderately coarse and very
