What are two major forms of propagation used in establishing turfgrasses and the advantages and disadvantages of each?
What will be an ideal response?
The two major forms of propagation are sexual and asexual propagation. The main
advantage of sexual propagation is that it is inexpensive; however, the main
disadvantage is that more time is required to establish a high-quality turf. Asexual
propagation has the advantage of being able to establish high-quality turf very rapidly;
however, the main disadvantage is that it is expensive.
