Illustrative material: A potato tuber, cuttings of the currant

Roots Come from Buds. We have now learned how 

 to rear young plants by planting their seeds. Many kinds 

 of plants may also be reared from buds. Some kinds are 

 reared from buds more often than from seeds. We

 is by layering. Without being cut off, one or more 

 branches of a plant are covered with soil. Sometimes the
