Tip Layering. — When the tips of certain woody plants are bent 

 over and covered with soil they may form roots and new shoots. 

 Then when the parent branch is cut off a new plant is left growing 

 at the point where the rooting took place. Black raspberries are 

 most commonly propagated by this method. (Fig. 30.) 



Plan with Raspberries. — After the crop of berries has been 

 picked is the best time to begin the propagation by tip layering. 

 Cultivate the soil between the rows thoroughly so that it is mellow 

 and moist and free from weeds. In a rather straight row by the 

 side of the parent plants bend down the longest canes, slightly 

 break them on the under side a few inches from the tip and cover 

 them with some soil at the wounded points. Scores or hundreds 

 of tips may be thus treated in a short time. If necessary clods of

earth may be placed on them to hold them down. In light sandy 

 loam it is sometimes necessary to hold them with pegs thrust 

 deep into the soil. In a few weeks these may be examined and 

 found to be provided with roots. The tips of the twigs which were 

 not covered will form fresh leaves or new shoots. When new 

 growth is thus established, cut off the parent canes connected with 

 the old plants. This may be done with a spade or pruning shears. 

 The new row of young plants may be left in place until late autumn 

 or early spring. They are then taken up and planted in the new 

 berry patch where they are to remain.
