 to be small. 



PROPAGATION 



The dewberry propagates naturally from tips, like the 

 black raspberry. If increase of plants is important, these 

 tips should be buried when their growth is about com- 

 pleted. Covering the whole cane to induce rooting along 

 its entire length would seem to be feasible, if speedy 

 methods are desired. Such a cane cut into pieces should 

 form many plants; and the prostrate habit of the plant 

 would favor such a method. 



Dewberries can also be propagated by root-cuttings, 

 the same as blackberries. The method for doing this is 

 explained in the chapter on blackberries. Since it is a 

 general rule that those plants which naturally propagate 

 by suckers also propagate most easily by root-cuttings, 

 a little more care may be demanded, and a larger percent- 

 age of failure may be expected than with blackberries. 



PLANTING 



The same general rules given for the planting of the 

 blackberry will apply to the dewberry, except that the 

 furrow to receive the plants need not be quite so deep. 

 The distance apart at which they are to be placed will be 

 largely determined by the method of training to be em- 

 ployed. If to be trained to single stakes, four feet apart 

 each way will be satisfactory; if to wire trellises, six feet 

 by perhaps three feet in the row will be more convenient. 

 If to be trained on low, flat, slat or wire trellises, even 

 a greater distance between the rows will be needed. This
