LOGANBERRY CULTURE IN THE NORTHWEST. 



By C. L. Lewis, Chief, Division of Horticulture, Oregon Agricultural College, 



Corvallis, Oregon. 



No phase of northwest horticulture has attracted more attention 

 during the past few years than that of loganberry growing. There has 

 been a wonderful development during this period. Tliousands of 

 acres have been planted and the industry now seems to be pretty well 

 established. 



About four or five years ago there was a considerable slump in logan- 

 berry growing. At that time the yield had reached considerable pro- 

 portions and there was no market for the product. They would not 

 ship very far, canning was unsuccessful, no one had attempted the 

 evaporation of the fruit and the juices had not been tried out. Con- 

 sequently the market was very limited and was easily overstocked. 

 The use of the berries through many new channels the last few years 

 has greatly stimulated the planting and development of the industry. 

 However, during the past year there has been very little planting owing 

 to the fact that many people feared the industry was being overdone. 



CULTURAL RANGE. 



The principal cultural range in the Pacific Northwest runs from the 

 Cascade ^lountains to the ocean, including a long strip of land in 

 western Washington and western Oregon. The loganberry will thrive 

 where the atmospheric conditions are not too dry, where the heat is not 

 too excessive and where very cold winter temperatures do not exist. 

 LTnless these conditions can be complied with, loganberry culture is 

 not very profitable. 



SITES AND SOILS. 



The berry is not particular as to the soil in which it grows. It grows 

 from the alluvial river bottoms to the red clay hills. It only demands 

 a soil of fair depth and of good drainage. However, it yields the best 

 in rich mellow loams. 



PROPAGATION. 



The plants are very easily propagated by tips. There is a belief by 

 some men that while the plants can be propagated by cuttings that 

 those plants propagated in this way are not as long lived as those which 

 come from good rooted li])s. 



TILLAGE. 



The tillage is very much the same as that which is adapted to other 

 small fruits. However, the larger growers are lieginning to feel that 

 there is danger in too much disking, and if disks are used in the patches,
