SUMMER PRUNING OF ROSES. . 



Sir,— Some of our roses have thrown up very high shoots. Should they be cut back, 

 and when ? 



Wm. McM., Niagara. 



Mr. EUwanger, in his book on " The Rose," advises the pruning of roses 

 early in the spring, emphasizing the importance of attending to it while the 

 plants are dormant and before the sap has pushed towards the upper buds. 

 The chief objects of this pruning are for the formation of symmetrical plants and 

 to promote the formation of bloom buds. He advises a severe pruning of deli- 

 cate growers, and a moderate pruning of vigorous growers. Besides this 

 pruning in March, he says that summer pruning is desirable with many varieties 

 of hybrid perpetuals, as soon as the June blossoming is over, in order to induce 

 the formation of flower buds later in the season. 



SUMMER PRUNING. 



Sir.— Should I do any summer pruning of young vines, or should I leave them alone 

 the first year until fall ? 



E. B. E., Peterboro'. 



Young grape vines should by all means receive attention during the first 



year of their growth. The proper way is to allow only one shoot to grow up 



from the root the first season ; all others should be rubbed off. This one shoot 



should be trained up to a stake,- that it may acquire an upright habit of growth. 



THE WHITE SPOTTED RICHARDIA. 



Sir, — The Spotted Calla received this spring is growing finely, but there are seven 

 small shoots, also, coming up from the bulb. Should these be permitted to grow now, and 

 detached later on ? or ought they to be broken down at once so as not to weaken the larger 

 one ? 



A. Smallfield, Renfrew. 



These suckers may be removed at any time when repotting the plants, and 

 used for propagation, which is very easy. It will not be wise to disturb the 

 plants at this season of their removal. The term Calla, so commonly given this 

 plant, properly belongs to a European marsh plant, Calla palstris. 



A FRUIT EVAPORATOR. 



Sir, — How and where might I get a fruit evaporator? 



E. B. E. 



We have received no catalogues of any Canadian manufacturer of evapor- 

 ators, but we have received several from the States. One of these is from the 

 American Manufacturing Co., Waynesboro', Penn., and another from the Zimmer- 

 man Machine Co.,. Cincinnati, Ohio. We would advise our correspondent to 

 write to one of these firms.
