HORTICULTURE

Detailed explanation-1: -Gardeners use several general methods to propagate plants asexually. These include taking cuttings, layering, division, grafting, budding and developing new plants from tissue cultures in a lab.

Detailed explanation-2: -Layering is a method of asexual propagation in which a stem is made to produce roots while still attached to the parent plant. The parent plant provides the new plant with water and nutrients while the roots are forming. Layering can be used for plants that are difficult to propagate using other methods.

Detailed explanation-3: -Grafting is a method of asexual plant propagation that joins plant parts from different plants together so they will heal and grow as one plant. This technique is used to propagate plants that do not root well from cuttings, to utilize superior root systems, or to maintain clonal production.

Detailed explanation-4: -The major methods of asexual propagation are cut-tings, layering, division, and budding/grafting. Cuttings involve rooting a severed piece of the parent plant; lay-ering involves rooting a part of the parent and then sev-ering it; and budding and grafting are joining two plant parts from different varieties.
