358 THE MONTHLY BULLETIN. 



they must be used sparingly and very carefully. One of the largest 

 growers in the state plows the ground toward the plants in the fall and 

 plows it away in the spring. He uses a gang plow and by going down 

 the row twice he can turn all the soil. He then follows with light 

 harrowing until the ground is level. 



COVER CROPS. 



A few of the growers are beginning to use cover crops. The main 

 objection to using cover crops, however, is that they become quite rank 

 in the spring and a little hard to handle. However, if they are plowed 

 under before they become too high, and if the proper precautions are 

 taken, they may be handled quite nicely. 



FERTILIZERS. 



At the present date very few fertilizers have been used in the logan- 

 berry patches. We are conducting experiments at the Oregon Experi- 

 ment Station, and have been conducting these experiments on the use 

 of fertilizers in loganberry production. We will give a report on the 

 same in the very near future. 



IRRIGATION. 



At the present time very few loganberry patches have been irrigated 

 as the loganberry is grown in a country where irrigation is rarely 

 practiced. Most irrigated districts have too severe winters and also 

 are subjected to considerable heat in the summer — more than the 

 loganberry desires. However, in some of the irrigated countries, logan- 

 berries are being grown to a limited extent. 



PRUNING. 



There is considerable difference of opinion as to the best method of 

 pruning and training. The majority of the growers are coming to 

 believe, however, that it is a good practice to cut out the fruiting canes 

 just as soon as the fruit has borne. We are urging this very strongly 

 at the experiment station because anthracnose, which is the worst 

 disease that attacks this plant, can be somewhat controlled \dy cutting 

 out the old canes and burning them promptly as soon as the fruit is 

 harvested. 



The question as to the proper time of training up the young plants is 

 also open to difference of opinion. i\Iost growers practice kicking in 

 the young shoots close to the vine during the early summer. They 

 sometimes put down little stakes every few feet in order to keep the 

 plants away from the cultivators and out of the way of the feet of the 

 pickers. Some growers practice, as soon as the old canes are taken out 

 in midsummer, putting the new shoots up on the wires and interwinding 

 them and spreading them at different times during the summer. Other 

 growers prefer to M^ait until fall and do the work at that time, while 

 still others maintain that the spring is the best time to put up the new 

 plants, believing that if they are left down all winter they are pro- 

 tected against excessive cold, should it occur. Some growers, however, 

 contend that if this is done, the yield is not so good, while others main- 

 tain that the yield is better. We are conducting experiments, however, 

 to prove such points. Some growers advocate spreading the vines out
