beverage. It thrives and is grown extensively in the Pacific 

 Coast states, but will not succeed in cold climates. The 

 loganberry is propagated by tip-layering, is trained on some 

 form of trellis, and is cultivated in the same way as the black- 

 berry. The phenomenal berry is somewhat similar to the 

 loganberry. Since localities where it will succeed are limited, 

 it is not cultivated extensively. 



THE EASPBERRY 



317. Among the raspberry types are the red, black, purple, 

 and yellow. The red raspberry propagates by suckers so 

 readily that it is likely to become a nuisance. On this account, 

 many growers plant in hills and cultivate in both directions. 

 Red raspberries are propagated commercially by root-cut- 

 tings. Black raspberries, or " black-caps/' are multiplied by 

 tip-layering. The yellow and the purple varieties may be 

 propagated by either or both of the methods just mentioned, 

 depending on the variety. 



All types of raspberries succeed best in cool climates, con- 

 tinuous hot weather being very unfavorable. They require 

 thorough cultivation and plenty of moisture, but the land 

 should be well drained. They succeed on a wide range of soils. 



Although some of the red raspberries tend to produce fruit 

 in the autumn on the same season's growth, for practical 

 purposes the fruit of all varieties may be said to be, borne 

 upon growth of the previous season. Therefore, old wood 

 can be cut out after fruiting or early in the following spring. 

 It is customary to head the young wood of the black rasp- 

 berries back to a height that will cause stocky, well-branched, 

 fruitful plants. This should be done with red raspberries also 

 in most cases. 



CURRANTS AND GOOSEBERRIES

 in cool climates. They withstand intense cold and survive
