Cutting Propagation Floral Careers Plant Propagation
Plant Tissue Types • Meristematic: these are composed of actively dividing cells and are responsible for plant growth. • apical meristems • lateral meristems (vascular cambium) • Permanent: these are composed of cells that are no longer dividing. They form the structure of the plant.
Types of Cuttings • Stem Cuttings • Leaf-Bud Cuttings • Stem Sections • Leaf Cuttings
Stem Cuttings • Section of stem about 4-6 inches long and having at least 2 nodes. • The basal end of the cutting is inserted into a rooting medium.
Three Possibilities for Root Formation • At the nodes. • At the cut end of the stem. • Between the nodes. • All 3 involve meristematic tissues.

Leaf-Bud Cutting • Consists of a leaf blade, petiole, and a portion of the stem containing a bud.
Successful Cutting Propagation • Make and plant the cuttings in such a way that all 3 rooting possibilities exist. • Use a rooting hormone. • Provide bottom heat. • Maintain moisture and humidity. • Avoid direct sunlight.
Propagation Medium • A good medium should be well-drained, yet have some moisture retaining capabilities: • 2 parts coarse perlite • 1 part sphagnum peat moss

Stem Sections • House plants that can be propagated using this method include: • Hawaiian Ti Plant • Dracaena • Dumbcane • Chinese Evergreen
Leaf Cuttings • A select group of house plants can be propagated using leaf cuttings. • Examples include: • Snake Plant • Begonia • African violet • Peperomia
