CUTTINGS AND LAYERINGS 



new plants by this method. The golden bell, or Forsythia, very 

 naturally multiplies by this method. Plants which are not com- 

 monly propagated by layering may be induced to do so if the twig 

 is wounded at the point where it is covered with soil, and if the 

 weather conditions are favorable. Willows, poplars, dogwoods 

 and others will easily form new plants in this way. 



The Strawberry has a special plan of propagation. Its run- 

 ners take root at the nodes. (Fig. 31.) 



Mound Layering.— This method obtains its name from the 

 fact that the soil is mounded up among the lower stems or branches. 

 The method is resorted to because of the fact that root division is

Fig. 31. — StrawberrieB and many other plants naturally multiply by means of runners which 

 take root at the tip or at nodes.

 soil. Plants may then be multiplied by division. 



too slow, or may not be possible because of there being only one 

 stem arising from the ground. 



When the soil is mounded up among the lower branches for a 

 season, roots will be sent from the lower branches into this soil. 

 (Fig. 32.) At the end of the growing season the whole plant may 

 be taken up and divided by cutting these newly rooted branches 

 away from the others. These may be planted as separate 

 individuals. 



Common Examples of Mound Layering. — The lilac, gooseberry, 

 quince, althea and others may be easily propagated by this method. 

 Indeed, the method is a very sure one, as it does not in any way 

 endanger the life of the parent.
