BLACK RASPBERRIES. 



Pruning. 



LACK raspberries are usually headed back when from i ^ 

 to 2 feet high. It is important that this heading-in be 

 done about as soon as the canes reach the desired height 

 rather than to leave them until considerably higher and 

 then to cut them off to the required point, for the laterals 

 then start low and the bush becomes stout and self-sup- 

 porting. It is a very general mistake to head back rasp- 

 berries too late or too high, causing the laterals to start nearer the top of the 

 cane and thereby making it top- 

 heavy. Fig. coo is a good cane, 

 and Fig. coo shows several un- 

 desirable canes. The laterals are 

 cut back the following spring to 

 a length of 12 to 18 inches, the 

 same as blackberries are. This 

 treatment also applies to the pur- 

 ple-cane varieties, like Shaffer, but 

 not to the reds, for these are 

 rarely headed-in at all. 



The red raspberries are very 

 seldom evaporated, and only the 

 Cuthbert is used for that purpose, 

 so far as I know. The red ber- 

 ries generally pay better when 

 given to the open market. Of 

 the purple berries, only the Shaf- 

 fer is dried in Western New York, 

 and it is doubtful if it is profita- 

 ble when thus handled, for it loses 

 too much in drying, and the mar- 

 ket for dried red and purple ber- 

 ries is very small. 



There are really only two im- 

 portant varieties in the evaporating 

 industry in. Western New York, 

 the Ohio and the Gregg.

 Yield of Raspberries. 



How much will an acre of raspberries produce, taking the average of three 

 crops ? Opinions differ widely. We could begin with zero on the one hand, 

 and rise to 6,000 quarts. In an inquiry made here in 1893, the average of 58
