Vegetative (Asexual) Propagation
Types of Vegetative Propagation
• Cuttings (stem cuttings, leaf cutting, root cuttings):
Begonias, Gardenias, Pineapples, Coleus
• Separation/Division: Irises, Sempervivum, Lilies
• Grafting: Roses, Walnuts, Apples, Apricots
• Layering: Diffenbachia, Rubber Tree (Ficus elastica)

• Use sections of the stem
which have leaves.
• Treat with rooting
hormone to promote root
growth.

Leaf Cuttings
• Uses a leaf section,
petiole, or a cutting of the
leaf.
• The cutting is then treated
with hormones to
stimulate root growth.

Layering
• This method is used mainly
with plants which naturally
reproduce this way
(blackberries & vines).
• A section of the stem is
scraped and buried.
• Roots grow from the buried
stem.

• The removal of corms or
bulblets from a parent
plant.
• The small corm or bulb is
then used for planting

Grafting
• Material from two
different woody plants are
directly joined.
• Used to create plants with
disease resistant or
dwarfing root stocks.
• Plants are specially cut
and spliced together.
