Two methods of asexual propagation

opinion

Asexual propagation is the best way to maintain some species, particularly an individual that best represents that species. Clones are groups of plants that are identical to their one parent and that can only be propagated asexually. The Bartlett pear "Two methods of asexual propagation" the Delicious apple are two examples of clones that have been asexually propagated for many years. Cuttings involve rooting a severed piece of the parent plant; layering involves rooting a part of the parent and then severing it; and budding and grafting are joining two plant parts from different varieties.

The potting soil, or medium in which a plant grows, must be of good quality. It should be porous for root aeration and drainage, but also capable of water and nutrient retention.

In order Two methods of asexual propagation a plant to form a new root system, it must have a ready moisture supply at the cut surface. Oxygen, of course, is required for all living cells. The coarse-textured media choices often meet these requirements. Most commercially prepared mixes are termed artificial, which means they contain no soil.

The basic ingredients of such a mix are sphagnum peat moss and vermiculite, both of which are generally free of diseases, weed seeds, and insects. Rooting media for asexual propagation should be clean and sterile. Cuttings are not susceptible to damping-off, but they are attacked by other fungi and bacteria which may come along in the medium.

Most commercially prepared media are clean when purchased.

Plant Propagation

The media should be low in fertilizer. Excessive fertility will damage or inhibit new roots. High-quality artificial mixes sometimes contain slow-release fertilizers. Coarse perlite alone can be used to start some cuttings.
