strawberry Rust. 



674. Sir, — I notice this season that on some of my strawberry plants which I take 

 to be anthracnose. Is the Bordeaux mixture as good as any for this fungus ? 



IloBT. Scott, Carluke, Scotland. 



The disease to which our correspondent refers is no doubt the strawberry 

 leaf rust which so largely interferes with vigorous growth of the plants of many 

 varieties. The Bordeaux mixture is the best remedy so far as we know. The 

 vines should be first sprayed with this mixture when the first fruits are set and 

 again as soon as the crop is harvested, and even a third application may be 

 given if the foliage shows the rust later in the season. In addition to this it 

 may be well to give an application of ammoniacal carbonate of copper just as 

 the first fruits are ripening, because at this time the Bordeaux mixture would 

 cling to the fruit and make it unsalable. 



Renewal System. 



ftTtS. Sir, — In the August No. you speak of training grapes the renewal system. 

 Would you please explain what this means? C. M., Montreal, Que. 



This has been explained several times in back Nos. of the Canadian Hor- 

 ticulturist, but, if desirable, will be given again with illustrations at the proper 

 season. It is the method of training adopted with continental varieties of grapes 

 by which the new growth is annually cut back to the old wood. Usually two 

 arms are grown upon the lower wires about two feet from the ground. These 

 are allowed to grow about four feet in length, when from each of them three or 

 four upright stems are turned. Every spring these are cut back to within one 

 bud of the old wood, or with some varieties every other upright stem is annually 

 cut back. In this way the new growth is always kept near the ground, the 

 vines are trained in a tidy shape and the finest fruit is produced. 



A Cheap Greenhouse. 



676 ■ Sir, — Would you please inform me whether a greenhouse 25x12 could be 

 satisfactorily heated from the furnace in the house ? Also, what would be the probable 

 cost of a greenhouse of that size. 0. F. B. , Kingscotirt, Ont. 



On pages 74 and 310 of volume 1892, some cheap greenhouses are 

 described and illustrated. Possibly one of these might meet the requirements 

 of our correspondent. We would ask any of our readers acquainted with this 

 kind of work to please write us an article fully answering our correspondent. If 

 drawings could be furnished to illustrate the article, we would have them 

 engraved and be much obliged for the trouble taken by the writer.
