they are more likely to winter-kill than upon one of a sandy or 

 gravelly nature, while upon the latter they need an extra amount 

 of plant food. 



Planting and Training. 



The time of planting, method of training and pruning are the 

 same as for the red raspberry. The distance at which they are 

 planted varies from two to four by eight feet where to be grown 

 in rows, to five by eight feet where to be grown in hills. In 

 fertilizing the blackberry field or plot the same kind and quantity 

 of fertilizer should be used as for the red raspberry. 



Varieties., Insects and Diseases. 



The varieties best adapted to the home garden or the field are 

 the same, and the Agawam, Snyder, and Taylor's Prolific are 

 certainly the best of those fully tested. No insects interfere 

 seriously with its growth, but the fall and spring "orange rust" 

 is often abundant and destructive. Spraying as for the raspber- 

 ries will in a measure overcome it, but it is better also to cut out 

 all rusted canes and leaves as soon as the}' appear.
