cut off when about three or four inches in 

 length. Cut them off just below a leaf joint, 

 and insert the cuttings in sharp clean sand. 

 A four-inch pot will hold several cuttings 

 until rooted. Place sufficient small pieces of 

 broken pot in the pot, before putting in the 

 sand for the cuttings, to act as drainage ; this 

 prevents the cuttings from rotting oftentimes. 

 Place the pot of cuttings in a warm shaded 

 place in the window, where the temperature 

 is about 60°. Pot the cuttings Off singly 

 into small pots when rooted, which will 

 usually be in four or five weeks from the 

 time they were put in the sand. 



Chrysanthemums like rich, fairly light soil. 

 Press the soil firmly around the roots when 

 potting or repotting chrysanthemums, as 

 loose potting does not suit them at any stage 

 of their growth. The pinching and after 

 treatment of the young plants will be about 

 the same as recommended for the old plants 

 before mentioned. 



Aphis or green fly, and the tiny mites call- 

 ed red spider, are the only insects likely to 

 trouble chrysanthemums in winter. Tobacco 

 water will do away with the aphis, and a 

 sprinkle of cold water, once or twice a week 

 on the foliage, will keep down red spider. 



Old plants of chrysanthemums can be 

 successfully wintered over out of doors or in 

 frames in favorable winters, if given some 

 protection. Some of the hardy pompone 

 varieties will even live in some of the most 

 favored localities, such as the Niagara 

 district, without protection, but the tender 

 hybrid Japanese and Chinese varieties sel- 

 dom winter over successfully even in frames, 

 or when protected, unless great care in re- 

 gard to hardening off, etc., is given them 

 early in the season, and close attention to 

 ventilating and covering given them during 

 the changeable weather conditions experi- 

 enced in early spring time. 



Qrafting Cacti. 



Sir, — How do you graft the Cactus and what 

 would you graft a Lobster Cactus on. 



H. D. K. 



The Lobster Cactus (Epiphyllum truncat- 

 um) succeeds best grafted on the Pereskia 

 aculata or Pereskia Bleo stock. The Per. 

 eskias mentioned grow readily from cuttings 

 placed in sand. Cleft-graft a small lobe or 

 two of the Lobster Cactus on to the Pereskia 

 stock in spring time, when the growth of the 

 Cactus is young and in a growing state. 



Clematis. 



Sir, — How do you propagate Clematis Jack- 

 manni, and can you recommend a good blue 

 Clematis ? 



H. L K. 



The Clematis is propagated by layering, or 



by root grafting. Clematis Raymond, pale 

 blue, and Clematis Hybrida Sieboldiana are 

 the best blues, the first variety preferred.

Tea Roses. 



Sir, — Is it possible to make a tree rose from the 

 H. P. Rose Mrs. John Laing grafted on the briar 

 stock, so that the rofe will be as vigorous and 

 hardy as when grafted low down^ or grown on its 

 own roots. 



Toronto. H. S. Keddle. 



Tree or standard roses of any kind are not 

 a success in Canada, planted out of doors. 

 Even low-grafted roses have to be protected 

 by junction of stock and graft (or bud) dur- 

 ing the winter months, by banking earth or 

 some protective material around them un- 

 less very deeply planted.
