Softwood & Semi-hardwood 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 relative humidity 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 in 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 hormone- ROOTONE 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 weaker
strength.
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 long.
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
