Advantages of vegetative propagation :

1. Plants produced by vegetative reproduction are genetically similar to parental type. Thus, the best varieties of potatoes, oranges, apples, etc., can be preserved by vegetative reproduction without loss of their fine quality. In this way, pure lines of desired types can be selected and propagated all over the world. 

2. This is quick method and by this method flowers and fruits can be produced early. 

3. This is more sure method of producing new plants than that of seed reproduction.

4. It is more economical for the plant because no energy is wasted in producing large and showy petals, nectar, fruits, seeds, etc. as in sexual reproduction.

Disadvantages of vegetative propagation : 

1. Due to overcrowding of large number of plants near the parent plants, there is severe competition between the members of the same species. Thus, many plants become weak and stunted. 

2. Over the time there may be degeneration of species due to lack of sexual stimulus. 

3. Due to absence of genetic Variability in vegetative reproductive structure, there may not be evolution of new species.
