Asexual Propagation
Softwood & Semihardwood stem cuttings
When
to take cuttings
after current or present seasons
growth has partially hardened
should be able to bend
Stem Cuttings
Collecting
cutting wood
parent plant that has made 2 to
6 inches new growth during
current year
early morning is the best time to
take cuttings
Stem Cuttings
Place
cutting in water
immediately after taking cutting
be sure to remember which is
the top of the cutting
cut bottom at an angle
cut top straight across
Stem Cuttings
Preparing
Container & Rooting
media
containers must have holes in
the bottom for drainage
medium should be sterile
mix medium before wilting to
assure uniform mixture
Stem Cuttings
Making
the cuttings
make as many 3 or 4 inch
cuttings as possible from each
shoot
cut bottom at an angle
allows more surface area to
contact rooting media for water
absorption
Stem Cuttings
include
2 or 3 buds on each
cutting
On hollow stems, cut just below
the node on the bottom and just
above the node on top
Stem Cuttings
Treating
and Inserting Cutting
“Root one F” rooting hormone
Chemicals which help cuttings
grow more quickly and grow a
larger number of roots
rooting hormones may contain
fungicide
Stem Cuttings
place
cutting in medium no
more than 2 inches deep
Do not press media around
cutting, water to settle around it
label cutting, include name of
rooting hormone used
Stem Cuttings
Controlling
the atmosphere
Keep R.H. close to 100%
plant loses water through leaves
(transpiration) can’t take up
water fast enough to
compensate without roots.
Stem Cuttings
Enclose
containers in clear
plastic
place out or direct sunlight
keep temp down
Stem Cuttings
Rooting
Check
for roots by holding
cutting and tugging gently
resistance = roots developing
growth on the tips or sides is
normal, but does not indicate
root growth
Stem Cuttings
harden
off when root ball is 2-3
inches
after hardening off can be
“lined out”
planted outside
Herbaceous Cuttings
Succulent
greenhouse plants
can make numerous cuttings
from parent plant
cuttings 2-6 inches long
Herbaceous Cuttings
remove
bottom leaves
roots will grow from the node
where leaves were attached
Use rooting hormoneROOTONE
not required
speeds rooting process
Herbaceous Cuttings
high
humidity
bottom heat helps speed rooting
Herbaceous Cuttings
Leaf
Cuttings
African Violet
Use leaf and petiole
Herbaceous Cuttings
Leaf-bud
cuttings
cut bud and leaf from stem
cut leaf to a smaller size
requires less moisture
Herbaceous Cuttings
firm
into soil, water and cover
in a moisture right container.
Can make many more cuttings
from parent plant than with
stem cuttings
rooting hormone should be
Herbaceous Cuttings
Root
Cuttings
Can be made from any plant
that will sprout or sucker from
the root.
Cut roots 1/8 to 1/2 inch in
diameter in pieces 1-4 inches
Herbaceous Cuttings
place
in sand in a flat
water
cover
with glass or plastic
when new shoots sprout move
plants to nursery row
ex: raspberry
